BTG bypass system designed and ran the characteristic

Summary: Mainly introduce the composition, function and protection control system of BTG bypass system which Zhuhai power plant 700MW aircrew uses, combine and design characteristic and real running situation, think the apparatus of the system of BTG bypass is reliable, the regulation of the control system is accurate fast, its good one makes and controls the important insurance that the function is aircrew’s safe operation quickly.

1.Apparatus and the system is always contracted by Japanese Mitsubishi Company to sums up the first stage of 2* aircrews in Zhuhai power plant of electric group in Guangdong of Guangdong Province, one hot the middle, circulate the intersection of steam dome and stove by force, have high connecting the intersection of bypass and system in series by two of low pressure. Bypass apparatus of system to regulate the bypass system by hydraulic power that Company produces, BTG of Swedish, the high, low-voltage bypass each has independent high pressure that resists the fuel station, adjust through electric liquid servo valve. The high, low-voltage bypass regulates the whole journey and holds, closes and needs 20- 30s normally, under the accident state, the high, low-voltage bypass can realize that open 3s all open quickly With closing closing completely quickly ,The high-pressure bypass reduces the warm water and is come from managing for the jellyfish, it is that the high pressure standing with the oil of high-pressure bypass resists the fuel system too that the high-pressure bypass reduces the warm water regulating valve, controlled by the electric liquid servo valve. The low-voltage bypass reduces the warm water and comes from condensing the water pump and exporting mother to manage. When this bypass of systematic designing requirements finish following function aircrews’ starting under the circumstances that the control system cooperates, drain device of vapour congealed into not in accordance with parameter requirement steam, make vapour that boiler export warm pigeonholing and washing vapour that requiring warm and vapour pigeonhole match transferring to, by vapour as soon as possible through bypass, thus shorten the time of starting and reduce working medium losses and start the expenses after the steam turbine trip, channel the surplus steam that the boiler produces into the vapour congealing device, the boiler maintains at the lowest load and runs steadily, realize and shut down the operation way not stopping the stove and drain the surplus steam into the vapour congealing device through the bypass after the generator get rid of load, the boiler runs under the lowest load steadily, keep the steam turbine dallying or leading the factory to run when the boiler vapour is pressed too high with the electricity, bypass open, reduce to empty to arrange vapour, prevent boiler from exceed, pigeonhole and retrieve working medium and protect the heat exchanger and then, , , until heat exchanger offer by the intersection of bypass and system coherent to flow return circuit again, make heat exchanger to receive abundant cooling again, avoid damaging braisedly.

2.The pressure of high-pressure bypass of control method of high, low-voltage bypass system of the control method of the high, low-voltage bypass system is controlled while starting in the aircrew, the high-pressure bypass controls the vaporized pressure of the starting course. The presuming value of pressure of the high-pressure bypass, for the presuming value of pressure of the main steam, it is a function of the load order, the control logic of the high-pressure bypass valve is shown as in Fig. 1, the high-pressure bypass controls the temperature to be 340 ℃, the low-voltage bypass controls the temperature to be 150 ℃.

3.In the aircrew starts when the bypass controls logic to be cool and lights a fire, when the main vapour pressure reaches 5.5MPa, the high-pressure bypass and low-voltage bypass open a minimum opening. The opening of high-pressure bypass is that 18%, two pieces of opening of low-voltage bypass are 8% respectively. When the mainly vaporized pressure exceeds 6.0MPa, the high-pressure bypass begins to be made and maintained the mainly vaporized pressure in 6.0MPa big gradually. When hotter vaporized pressure exceeds, low-voltage bypass begin, turn on loud gradually, keep and then hot vaporized pressure in 0.8MPa. Hot light a fire, while already as the pressure of the steam dome rising after igniting, the high, low-voltage bypass begins to turn on to minimum opening. When the mainly vaporized pressure exceeds 8.0MPa, the high-pressure bypass begins to open big gradually, maintain the mainly vaporized pressure in 8.0MPa. When hotter vaporized pressure exceeds 0.8MPa, low-voltage bypass begin, turn on loud to keep and then hot vaporized pressure in 0.8MPa gradually. Extremely hot fire, after there are burning devices to put into operation, high low-voltage bypass begin, open to minimum opening promptly. When the mainly vaporized pressure exceeds, the high-pressure bypass begins to open big gradually, maintain the mainly vaporized pressure in 11.2MPa. When hotter vaporized pressure exceeds, low-voltage bypass begin, turn on loud gradually, keep and then hot vaporized pressure in 0.8MPa. After the steam turbine washes transferring to and load, enter the increase of vapour quantity with the vapour machine, the high, low-voltage bypass is closed gradually.

Thesis summary: Tender evaluation most key link under bidding, a commonly used one think method most low to comment, mark a price law, comprehensive point system, the intersection of value and the intersection of coefficient and law,etc. at present. It should be from evaluating this particular tender evaluation method of the factor that the electric goods and materials call for bid and appraise the method, evaluate the reasonable assignment of the factor coefficient, stipulate wastely that mark the standard, offers requirement and tender price and revises the method etc. and improves the tactics.

With the rapid development of China’s electric project construction, the bidding system must use application and popularization in the electric purchase of goods and materials of China. However, a lot of electric Huahai Materials Co.s in China will still face a lot of questions in the course of managing bid at present. Call for bid to electric goods and materials on one hand itself have, call for bid procedure to be unstandard, question not unified of the way that all parts evaluate the tender; On the other hand to the bid administrative department of goods and materials, the existing statistical analysis means is not flexible, inquire, check inconvenient to lead to the fact consuming a large number of manpower and materials, the inefficiency; Further aspect is most important on the other hand too, the intersection of China and electric goods and materials appear reasonable effective the intersection of appraisal and method yet call for bid, at present.

What is called method of evaluating the tender, it is the concrete method of using the tender evaluation standard already confirmed in bidding documents to evaluate, compare, choose to be recommended the bidding candidate. Improve the electric purchase of goods and materials and appraise the method, to constructing the harmonious power industry, have positive meanings.

First, appraisal method used at present

1 Comment the marking a price law the most low

Most low to comment, mark a price law mean, regard price as main factor, confirm, win a bid candidate tender evaluation method of supplier, namely on the premise of all meeting the substantive requirement of bidding documents, evaluate the lowest quotation according to the unified price key element, in order to propose the candidate supplier as winning a bid of the bidder of the lowest quotation or win a bid of the supplier’s tender evaluation method. Evaluate the tender in the committee according to the tender evaluation standard confirmed in bidding documents in advance, convert factors such as relevant technology, commercial affair, supply range beyond the price,etc. into the currency, and calculate the corresponding weighting, then add these data and tender price, calculate, obtain new the intersection of valuation and price, namely evaluate the tender price, evaluate the tender the cheapest bidder will give a recommendation as the bidding candidate.

2 Comprehensive point system

The comprehensive point system refers to on the premise of meeting the substantive requirement of bidding documents to the maximum extent, after evaluating synthetically according to every factor stipulated in bidding documents, must assign the supreme bidder as winning a bid of the candidate supplier or tender evaluation method to win a bid of the supplier in order to evaluate the tender. The comprehensive point system usually divides the score into two parts, namely: Technology divides and divides with the commercial affair. Technology divide include, throw the intersection of newspaper and the intersection of apparatus and technological situation mainly ‘ Apparatus technical indicator, brand,etc. , submit a tender and supply the market conditions condition with ‘ Financial situation, prestige, achievement,etc. , after-sale service situation The intersection of stock and issue, guarantee, maintain respond to, the intersection of quality and duration of insurance,etc. , to response intensity of bidding documents,etc.; Commercial affair give it is the intersection of bid and quotation of supplier that score, concrete score evaluate the tender ” the method of scoring ” in the method according to bidding documents generally Calculate and obtain, adopt and grade synthetically the main factor needing to consider is: Price, technology, financial situation, prestige, achievement, service, and the response intensity and corresponding proportion or right value to bidding documents,etc..

3 Coefficient law of value

The products or service which bid invitor provides for bidder through combined wisdom and organized activity carries on value analysis to actually evaluate the tender, should say, to evaluate the tender is more rational than to evaluate the tender with the law of comprehensive assessment by analytical method of value. The tender evaluation method after the analytical method of introducing value is improved to the point system is called the coefficient law of value. The value coefficient here, refer to bid invitor’s proportion between fee and income. , as the intersection of bid invitor and fee, other every evaluation quantized to have result and comprehensive assessment assign regard as the intersection of bid invitor and income promptly in factor by tender price that evaluate, the latter except that before namely value coefficient. The expression formula is:

Value coefficient =Tender price divided / evaluated in comprehensive assessment

The value coefficient demonstrates the bid invitor pays benefit that the unit cost obtains. The bid of value with supreme coefficient, can make the bid invitor realize the greatest value of the unit cost, namely realize the maximization of fund value, so the bid that the coefficient law of value is supreme with the value coefficient wins a bid.

Second, appraise the method and improve the tactics

1 Evaluate the factor and choose

Have been chosen the particular tender evaluation method, just mean needing to make the corresponding tender evaluation standard in bidding documents clearly. The standard should stipulate clearly that all evaluate factor and weight coefficient to evaluate the tender, this is a requirement for evaluating factor openness, it is for the response clearly that makes the evaluation factor that the bid invitor puts forward get the bidder too. The evaluation factor of submitting a tender can generally be divided into technological factor and commercial factor two big class. Technology the intersection of evaluation and factor include service ability and the intersection of appearance and performance mainly ‘ Aesthetics , applicability, dependability, maintenance, security, the commercial affair evaluation factor mainly includes the goodwill of the products, bidder’s prestige and achievement, tender price, project deliver one, terms of payment, after-sale service, technical training, other favorable conditions for a check etc.. The evaluation factor of products service ability mainly has products technological advance and ripe, function quantity and characteristic,etc.. It needs mainer technical indicator and production technology to judge the technological advance of the products; It needs to compare products surface material, surface handsome in appearance are dealt with etc. to judge appearance performance; It needs to compare whether the products function work well, be enough or have expansion ability and products required to meet the particular environment or meet the ability that the environment changes to judge the applicability; Judge the mean free error time MTBF that dependability needs to compare the products , the international standard quality system that the products pass authorizes, measures the report of test and assessment of the department in the authority, or analyze design reliability of the products, making reliability,etc.; Judge the maintaining maintenance tactics of needing to analyze product design, such as standardized intensity, maintenance design or guaranteeing the avoiding maintaining and designing etc. of high dependability of products spare part; It accords with the regulation of national standard to judge the security index of needing to be which examines the products of security, especially force the standard regulation, has already authorized through the safety sign of the authoritative organization. The concrete choice of the technology evaluation factor to the bidding project, should consult expert’s opinion, catch and mainly evaluate the factor, and consult the national standard or sector standard of the subject matter, technological content and index of evaluation factor that will choose are clear and thinning.

Electric Liaocheng power plant 2027t/h ” W ” of China The flame boiler is formed burntly and accumulating the dreg reason analysis

Summary: This text directs against the mountain electric Liaocheng power plant 2027t/h ” W ” of China The flame boiler is formed burntly and accumulating the dreg phenomenon, combine apparatus of this boiler, system, way characteristic of running, network analysis boiler is formed burntly and accumulating the danger, boiler of the dreg to form burntly and accumulating condition, course, 2027t/h ” W ” that the dreg forms Flame it is burnt accumulating concrete reasoning of dreg for boiler to form, propose, solve boiler, form burnt accumulating the intersection of dreg and difficulty that problem store in. Form burntly and accumulating the dreg problem, guarantee boiler security, economical operation in order to solve, on the basis of testing, analyzing, summarizing in a large amount, have taken a series of feasible measure, do a large number of work, make a boiler of our factory # form burntly and accumulating the dreg phenomenon and is basically controlled. But special because of the boiler structure of our factory, in addition very complicated that the knot is burnt and original, accumulates the dreg, vary with external condition, the boiler stills have possibility to continue happening to form burntly, accumulates the dreg. As a long-term task, every professional and technical personnel also needs to continue making great efforts, suggest ways and means in order to solve and form burnt, this difficult problem of storing up the dreg fundamentally finally.

Brief introduction of an apparatus

The # of electric the first stage of the project 2* 600MW aircrew of Liaocheng power plant of China of mountain a unit finished 168 test run smoothly on September 11, 2002, transferred and produced as a trial. The boiler adopts the products of British Mitsui Babcock company, the type is MBEL-2027/17.30-1 type; Pattern for precritical circulating naturally and the intersection of W and flame, single burner hearth, one hot the middle, equilibrate, ventilate, solid state rank the dreg steam dome stove; The boiler adopts the whole steelframe of high strength bolt to suspend the structure in midair.

Covered with and cooled the wall with water around the boiler furnace, cooling the wall with water makes up the main part of the circulatory system. The cross section of burner hearth is the octagon under the circumstances that the stove pushes the area, the cross section of upper burner hearth is the rectangle. Burner hearth size It is long and * * high mm wide : 26680* 10488* 51153 Top ; 26680* 21642* 51153 It is the biggest . It is that the membrane type composed of one block of tubes of fin that the case of second line of a couplet drawses cools the wall with water to cool the wall with water. The back wall cools the wall with water after the stove elevation 40298mm punishes the fork, a part cools the wall with water vertically upwards, form the top of the back wall to suspend in midair and manage; Another part branching cool with water wall make up the boiler and roll over the flame corner roll over, in the tube. Make up and roll over cooling the wall with water and in charge of being distributed as sector on the horizontal flue bottom of the angle of flame, form the horizontal flue bottom and cool the wall with water and export the convection to restrain. In addition, cooled the wall with water and punished the fork in elevation 27500mm from side to side in the back wall, a small part formed the underpart of the stove wall to suspend upwards in midair and manage, another part cools with water and rolls over and forms the stove to join in the wall tube. For guarantee, it circulates to be safe and reliable, whorl cool the wall with water in charge of in the intersection of corridor and the intersection of entry and position adopt until the intersection of stove and bottom arrive, it is fluorescent lamps that other parts cool the wall with water.

Ago and back wall cool the underpart of the wall with water form 50 degrees ‘ With contained angle of the horizontal plane The stove bottom of Model V, form the cold hod. The underpart of the steam dome connects 6 out and concentrates on dropping and managing, then is dispersed the delivery pipe by 64 and cools the case connection of every second line of a couplet of the wall with water.

Boiler ceiling and tail flue coal device the above in the province Ago, back wall, both sides wall and lasting parting until ceiling lasting heat exchangering, in order to guarantee the tightness of the furnace roof and flue.

Have rejected one grade of over heat exchangers of heat exchanger and the end before the top of burner hearth has been fixed up vertically, assign heat exchanger at the horizontal flue, assign at low temperature passing heat exchangering and the intersection of province and coal device respectively from top to bottom in the intersection of tail and the intersection of flue and shaft; The exhaust gas turns to and flows through empty pre- devices, electric dust removers after coal device of province, is discharged through the chimney by the air-introduced machine.

The structural sketch map of W flame boiler is shown in Fig. 1:

Structural sketch map of Fig. 1W flame boiler

Pass heat exchanger adopt second spray water, reduce warm, decorate in pass heat exchanger and reject, pass heat exchanger and reject, pass heat exchanger and the end between the grades of over heat exchanger ago ago at low temperature separately, reduce the warm water and come from the feed water pump and export the pipeline behind the electronic door. Heat exchanger adopt inject hot the intersection of temperature adjustment and way of wind into stove bottom and then, set up and then hot steam spray water and reduce the warm device at the intersection of heat exchanger and hot vaporized pipeline of entrance, it reduces warm water and comes from the feed water pump grade.

The boiler is furnished with two three points of turning of storehouse round air preheaters, the exhaust gas flows from top to bottom in the preheater, the air flows from bottom to top, the once wind / outlet temperature of wind two times designed is 366.7 ℃/ 335 ℃.

Boiler furnished with 2 move leaf adjustable the intersection of axle and forced draught blower, 2 at odds with the community or the leadership pairs of person who suck of flowing etc. air-introduced machine, 2 at odds with the community or the leadership pair suck formula one air blower and 2

Because boiler this use anthracite, adopt the intersection of Model W and the intersection of flame and firing method, fix up under the 48 slot type penetrating, assigning spouting of burning etc. evenly at fire push around burner hearth, assign two time wind spout and a wind spout interval,20% airs combustion-supporting as three winds in the past, last burner hearth at the underpart openings of back wall.

Accumulating the dust in order to remove on the heated surface of boiler, has assigned 22 pieces of V92 type short extension-type to blow the dust device around the burner hearth; Until screen type pass heat exchanger and grade pass heat exchanger, heat exchanger again and assign 28 RK-SL type blow dust device by long extension-type by wall by elementary over both sides of heat exchanger the end; Assign 6 RK-SB half extension-type blow the dust device in the intersection of province and the intersection of coal device and the intersection of both sides and wall. It blows gray mediums to be to come from person who reject pass the intersection of heat exchanger and export, unite steam of case.

The slot type makes the main characteristic of shooting burning device:

? The upper coal powder is concentrated, and low-speed once wind / fuel mixture, in order to heat fast and light a fire ahead of time;

? Wind two times of high speed, in order to promote the long flame to launch;

? It is not the air of swirl that sends into, in order to limit the initial turbulence, supports to mix gradually;

? Wind three times of low-speed, in order to make the whole flame launch, and exercise restraint in burning in products NOx takes shape;

? Gush out four lines of coal powder trough of group of firing device to fix up each time, in order to keep outside recycling mode and internal flame penetrability.

Lower the intersection of burner hearth and hyperpyrexia load area assign the refractory brick to defend, fire, bring: Stove join below in front and at the back of the intersection of refractory brick and total coverage is for 616m2, include 60% front wall and back wall ‘ ,4 intact ones pour the angle ‘ Four small corners of the lower burner hearth ,There is no refractory brick on wall on both sides of burner hearth.

The boiler is designed the equilibrium to ventilate, very single side runs. One the intersection of wind and bellows decorate under turning round layer, cold, through entering the machine for rubbing coal and drying and carrying the coal powder and entering burner hearth after the regulation hot wind, the wall has powder pipelines of wind of 12 once respectively in front and at the back of the boiler.

Annular two bellows decorate in lower top of burner hearth, in front of boiler, draw No. 6 respectively at the the intersection of back wall and bellows 2 times. Enter burner hearth downwards, offer the air amount required to burn from the pushing department of the boiler. Front the intersection of wall and 6 No. two tunnel for electronic guard, can regulate two air volume at any time in operation. Windscreen board two times on the back wall is manual guards.

It is on the bottom that wind entry three times is fixed up in a lower part of the burner hearth, about 20m places of elevation. Draw from annular bellows two times, the No. of the front and back wall every 6. Because of making powder system in order to press the blowing type directly, wind three times here is different from the negative pressure type and make that kind of refered wind three times with light coal powder in powder system. On the bottom to assign No. 6 Branch to start the oil gun on front wall of the burner hearth. So main function of the wind three times is for No. 6 Branch to start the oxygen demand of oil gun when the boiler is started, and under the normal running state, air volume of the wind three times should increase with rising of the boiler load, the amount of oxygen offered for coal powder air current of tip, lengthen the time of catching fire, and prevent forming the reducing atmosphere in the burner hearth of underpart. The burner hearth bottom pours into the hot wind, connects tunnel two times exported from the empty pre- device, there is No. 2 in all, have one regulation guard all the way while being every, divide for No. 2 Branch respectively behind regulating the guard, No. 4 Branch enters the burner hearth underpart altogether. Only fix up the bottom on the back stove wall. The vapour of the heat exchanger is warm that the function of the hot wind of stove bottom is regulated in operation, temperature and flow reach the maximum when about 80% BMCR. Its another function is stripped as the first grade before the boiler is started.

Though the budget of European government faced the predicament, the regenerated energy facilities of Europe reached record-breakingly and horizontally and probably increased powerfully over the next 10 years last year. This is EU Committee EuropeanCommission View jointly in a report which the research center delivers in Brussels. This report showed, ones that will not sanctioned supporting solar energy power generating economy on the German parliament in development speed of the regenerated energy were cut down, encouraged the similar cut down and is slowed downing of the respect with Spain in the solar energy last year.

German solar energy company has warned, the cutting down of proposal stimulates rewarding and damaging its solar energy industry, but the reputable scientist of main author, joint research center of the new report takes exception to warning deserved, very capable in describing the serious situation that is obviously exaggerated to persuade the Congressman’s group on the question of solar energy. Though the solar energy panel manufacturers of Germany may face the challenge, there will be good profits in the installation company.

EU Committee estimates, in 2009, European public utilities company and developer install 10.2 gigawatt GWs of new wind-power electricity generation playground and 5.8 gigawatt GWs of light and bend over board and solar energy heat and generate electricity, the power of power generating of regenerated energy accounts for 62% of the power of all new power generating. Last month, European Union that member state submit to Brussels plan declare their purpose, install a large number of apparatuses in order to meet regenerated energy of European Union to guide the plan E.U.’ sRenewableEnergyDirective The goal set up last year, this would promote the European use for regenerated energy, from accounting for 20% from 8.5% to 2020 of total energy consumption.

The regenerated energy is guided and planned, that the general headquarters lie in Abu Dhabi AbuDhabi now according to helping to discuss and decide International regenerated energy organization InternationalRenewableEnergyAgency ency Officer say,goal European country is with them,in order to preventing from to come from Luxembourg Luxembourg European Court of Justice EuropeanCourtofJustice Heavy punishment. The goal that should be fulfilled is a really binding goal. This can not be neglected.

The light of Germany and Spain bends over and stimulates rewarding – -The purchase tariff needs public utilities company to buy the generating equipment of regenerated energy at high price – -Cut down, the reason is they, to having too generous price of the solar energy panel. It is a course not perfect to weave the purchase tariff meticulously, because the government lacks the internal information for producing cost. Yaeger – agree Germany and tariff of Spain make too high by the intersection of Val and dish, having offered the too high profit for Utilities Electric Co., thus impose on public utilities and unfair cost of their consumers.

Look forward to the future, German expecting extensively the anxiety that the change caused has been really further stimulated and increased to purchasing price of regenerated energy passed – -It is temporary at least. Public utilities generated electricity on the solar energy of the roof the price that must be paid to Utilities Electric Co. has dropped by 13%, in October, further cut down by 3 percentage points. The expert predicts, the developer is eager to finish the project before cutting down and stimulating the fund in Germany, they will install up to 8 gigawatt GWs of apparatuses in 2010. It is estimated, Europe only bends over the power generator and probably doubles, from 5.4 gigawatt GW to 56,000 gigawatt GW of last year.

Germany will be a strong market after 2010, because of the new regulations, make Germany further adjust and fix the purchase tariff of the solar energy power generator at a certain level. The intersection of Germany and environment department hopes the annual installation amount is among 3 gigawatt GW to 3.5 gigawatt GW. If the demand is lower than this range, the purchasing price will be improved automatically. By 2020, 40- 50 gigawatt GWs of solar energy is stiff to run in Germany, this is probably all nuclear energy, coal and a high level most of half of power plant of natural gas certainly, in average year, the annual solar energy is stiff to offer the operation at full capacity of about 1000- 1500 hours, the utilization ratio is only 11%- 17%, and the traditional power plant can run with the supreme capacity in most of the time.

Because the country of taking the lead in race like Germany and Spain has cut down and stimulated rewarding, the other countries of European Union, are promoting one’s own industry actively such as France, Italy and Britain. According to European Union’s regenerated energy order E.U.RenewableEnergyMandate ,Britain must make its capacity of regenerated energy increase by 5 times, is up to 15% by 2020. For ty offer and purchase the intersection of solar energy and panel and other small-scale the intersection of regenerated energy and system go on power that generate electricity offer and purchase April such as order such as regenerated energy Price.

The British coalition government elected in May of this year is considering the purchasing price used in the power generating project of the scale of public utilities. The purchasing price will be supplemented – -Instead of replacing – -The regenerated energy debt RenewablesObligation directed against the electric retail trader in 8 exists in it ,In the following ten years, regenerated energy quota standard set is probably 3 times of growth, reach 30% which transport the electricity.

The second economic recession that a lot of economists predict next year may make the governments of various countries cut down the support to regenerated energy. But he says, the employment opportunity advantage offered by regenerated energy will inhibit that kind of possibility. He say according to estimate regenerated energy offer 500,000- 70 employment opportunity of Wan for Europe. Among them is less than 20% of the posts that is the manufacturing industry, may transfer to abroad.

Bigger worry is the support that the government will not convene the party, in order to reform the transmission system of Europe. What the electric wire netting of Europe is still used limitedly is interconnected and formed after the electric wire netting of every country is pieced together, opposition to the new transmission line of electricity of monopoly and place that it is deep-rooted that this is. So, assemble badly and become the very crux that intermittent regenerated energy that European Commission estimates generates electricity. The strong one is interconnected to let every area and its neighbouring country share the extra regenerated energy in most of the time, import the electricity when the wind subsides, the sunlight can’t shine.

An important electric connecting wire between Spain and France is advancing because of the involvement on the senior level – -But only neat NicolasSarkozy in the Sa ‘s of French president Nicholas Agree, share, transmit electricity line lay in case of underground cost permitted with the intersection of Spanish and colleague of him. The expert says, has already struggled for 20 years for this lifeblood between France and Spain, have reached a solution. The Sa ‘s is neat and EU Committee is that this has paid push work hard very.

Drive, discharge the electric automobile of any harmful gas only by the electronic motor, come on stage with glittering appearance in Japan again as the car in environment protecting mode of new generation. Nissan Motor is after Mitsubishi motor corporation introduced the small-scale electric automobile iM IE V last June, December 20, the electric automobile ” LEA F ” researching and developing it Introduce to the market ceremoniously. Has sold 6000 by the end of March of 2011 in the original plan, the result is booked quickly, users order the car now, should be to could see the car now after April of 2011.

Electric automobile ” LEA F ” Can take 5 people, can walk 200 kilometers to charge once, it is equivalent to 1/3 of the ordinary car, the lowest price is 3764250 Japanese yen 100 Japanese yen is nearly equal to 8.05 yuan ,Remove the government and subsidize the part, users only spend 2984250 Japanese yen, are similar to price of ordinary medium-sized car. Can be charged with the home power, avoid the power consuming peak, it is cheap to charge the electric rate at night, the car owner goes out, can be operated and charge with the mobile phone.

Nissan Motor had technological advantages to develop the electric automobile, produced and met the crisis in management the day before yesterday 10, but the study on key part battery of electric automobile and motor has not been disconnected, so can produce the key part with very strong competitiveness. Toyota Motor Corporation puts forth effort to develop the mixed motive force car, gets ahead of others in mixed motive force car at present. Nissan wants to change the inferior position of oneself in technology through developing the electric automobile. However, the car in environment protecting mode of new generation does not have electric automobile only, except Toyota Motor Corporation plans as using the car except encouraging electric automobile to compete in the market in 2012 at short range, as generally taking advantage of using the car and also introducing and charging the mixed motive force car PH V ,In power-saving technology, Toyota Motor Corporation strives to continue keeping one’s own advantage within some time of future. Honda Motors Co. is unwilling to be lag behind too, determine to introduce the electric automobile and charge the mixed motive force car in 2012.

In addition, people seem to have higher expectation to the electric automobile. Electric automobile and battery which charges the mixed motive force car can store the power consumption from one day to 3 days of general family, so, can be conversely for use in family and electric. Intellectual electric wire netting enter common people after the house in the future, wind-powered electricity, solar energy person who generate electricity regenerated energy to can charge the mixed power bus to charge for the electric automobile, electric automobile and charge the mixed power bus, charge, can also offer the power for family, make the car become the battery walking. Energy operation method, perhaps very great change will take place in the life style of the family.

The ordinary car supplements energies to lean against the service station, there are more than 40,000 service stations in Japan, spread all over it all over China, very convenient, not enough that needn’t worry about petrol to go away by car. It is different if electric automobile goes away, it is insufficient to charge the apparatus, will meet trouble. Whether the electric automobile could popularize the key and have enough charging stations, Nissan Motor makes an appointment and sets up 200 charging stations in China, Mitsubishi motor corporation makes an appointment and sets up the charger in 700 shops of China, two companies have already reached an agreement, the electric automobile can be shared and set up 900 all over China are charging the apparatus. By 2020, the government plans to set up 5000 and charge facilities. But it is still very inconvenient to buy the electric automobile at present, first, charge few apparatuses by the expressway, it is pitiably little to second, charge facilities, whether have bottom to could reach the next customer of charging station after a charging station is charged in the heart. Because originally charged and run 200 kilometers at one time, on condition that block up and use the air conditioner, can only walk 100 kilometers. If the car rechargable battery wears out, the travel distance is shorter, drop anchor on the road and suffer unspeakably. So car owner fill just electricity must decide where does it charge next time. In order to solve this problem, Nissan Motor has specially disposed the information system for the electric automobile, the intersection of battery and surplus send out the warning to the car owner when being enough to hold electric consumption, can find the nearest charging station through Internet. When set out, can confirm charging the state through the intellectual mobile phone. The subject not still solved at present is to charge the speed, are charged for 30 minutes once, can supplement 80% of the electric consumption, and the ordinary car refuels and only spends one minute. So, it is a subject to be solved urgently to develop the fast charger charged more quickly.

From world-wide to come, look, because last oil crisis and U.S.A. of century strengthen the environmental regulation, appeared the electric automobile to develop hotly for several times, but because charged travel distance near once, charge long time, can not popularize. Now because people pay attention to the environmental protection and development of information technology more and more, electric automobile become of new generation best choice of car, according to folk to investigate the intersection of organization and the intersection of Fuji and economic prediction of Company, by 2016, the market scale of world of the electric automobile will reach 370,000, will reach 1,750,000 by 2020. Orld contends for, during the a very long time in the future, the car in environment protecting mode of new generation will become the main battle field that the manufacturer of car of the world contends for.

The network news of international energy: The lasting rise of long-term aridity and fuel price of surrounding area of the power station has already brought the serious energy shortage situation to Tanzania, action of forcing state-run Utilities Electric Co. to adopt and frequently losing electrical power.

State-run development of the country of Tanzania Company National Development Corporation, is abbreviated as NDC Hold the share of 50% of this project and electricity of east African and pool Co., Ltd. Power Pool East Africa Limited, a privately owned company . The concrete financing detail is still not clear at present.

Tanzanian electricity mostly come from with the water and electricity dam, the natural gas generation stored in island Songosongo of open waters is close to 300 megawatts.

It is reported,Tanzania to demands electric last 900 megawatts,but last 800 megawatts generations one’s own of it.

State-run electric supply company TANESCO of Tanzania Had already announced since January 1, 2011, would raise 18.5% of the tariffs.

” wind energy kingdom ” Denmark develops the wind energy industry in a more cost-effective manner in recent years, wind-power electricity generation increases steadily. At present, develop the windward strength power generating field of large-scale sea and reduce the developing focus that the cost of electricity-generating of windward strength of sea has already become Danish wind-powered electricity trade. On the whole, industry’s prospect of Danish wind energy becomes better. What deserves to be mentioned is, China and Danish wind energy cooperate in having enormous potentiality.

Wind-power electricity generation increases steadily

Danish timber, coal and other mineral resources located in North Europe are relatively poor, but there is strong wind energy, its smooth terrain and long coastline are the advantage of developing wind energy. At present, wind-power electricity generation account for the intersection of Danish and 20% that electricity supply probably, in steady-state growth. The wind-driven generator of Denmark is in the world-lead level too.

Began since the eighties of last century, Denmark began to develop regenerated energy relying mainly on wind energy and biomass energy in a more cost-effective manner. Denmark has already become leading the runner of regenerated energy field of the world nowadays, its proportion in China’s total energy consumption of regenerated energy increases year by year. By May of 2010, there will be 5052 typhoon strength turbines in Denmark, the total installed capacity reaches 3545 megawatts.

According to the wind energy development plan by 2020 that the Danish wind energy association puts forward, the proportion that wind-power electricity generation accounts for total generation should rise to 50% from present about 20%. Danish climate and Ministry of Energy are released the research report and claimed on September 28 this year, Denmark is expected to shake off dependence on fossil energies such as the coal, petroleum and natural gas,etc. completely in 2050.

The maritime wind-powered electricity becomes the developing focus

At present, develop the windward strength power generating field of large-scale sea and reduce the developing focus that the cost of electricity-generating of windward strength of sea has already become Danish wind-powered electricity trade.

The data of world wind energy association reveal, it has already sea windward strength turbine aircrew equipped 2500 megawatts in the whole world to be present. The insider expects, by 2020, only the total installed capacity of the maritime wind-powered electricity in Europe will reach 40,000 megawatts, this is equivalent to 5 times of Denmark’s total generation at present.

“The market of windward strength power generating of sea develops powerfully. We can see, by 2015, the installed capacity of the maritime wind-powered electricity will increase by 5 times, on this basis, increase by 3 times by 2020. This market has enormous export potentiality for us, so we must develop maritime wind-powered electricity technology in order to guarantee the international competitiveness of Denmark in the field of wind-powered electricity in a more cost-effective manner, ” Danish wind energy association’s Vice President Jacob and Hall’s Sri Lankan specially says.

According to the report of the Danish energy administration, the Danish energy administration has explored and appointed 23 maritime wind electric fields of the surrounding waters of Denmark since 2007, it is estimated the total installed capacity of 23 wind electric fields will reach about 4600 megawatts.

It is easy to find out, it is the center of the Danish wind energy industry in the future to develop maritime wind-powered electricity. And to the wind electric field by land, the planning of Denmark is, increases the quantity of the large-scale air blower and eliminates some outdated small-scale air blowers.

China’s red wind energy has broad prospect of cooperating

China has already regarded developing new energy and energy-conserving emission reduction as strategy direction and fundamental state policy of economic and social sustainable development. And Danish technology and experience in developing regenerated energy and enabling especially the wind and tackling climatic change occupy world top. No matter between the aspects of government or enterprises, China and Denmark have very good cooperation will and potentiality.

Denmark is that Europe launches the cooperative countries of technical assistance of regenerated energy with China initially. 2005,of be if you can’t last wind energy the two governments, last cooperative partnered,it and start by regenerated energy technical assistance project at 2006 – -China’s red wind energy development projects, the bilateral collaborative project of red first wind energy field in this is too. It is February this year,of start both sideses red in being getting wider to involve surface by regenerated energy development projectses red. In addition, the renewable energy cooperation among the red cities of China has been further developed.

Denmark links Stuss global and leading air blower manufacturers, and a forerunner of China wind-power electricity generation market too. Since installed the first batch of air blowers of the Chinese market in Shandong and Hainan Province 1986, linking Stuss at present, already 13 provinces in China have installed the air blower, and there is the largest integrated wind energy apparatus manufacture base in the world in Tianjin.

Link Stuss and regard China as the global wind-powered electricity field to develop the most important market all the time, and is increasing its input in Chinese financial resources and manpower constantly. On October 12 this year, link Stuss and announce formally that establishes the technological research and development centre in China, this is the first technological research and development centre that an international air blower manufacturing company set up in China.

Danish climate and energy minister Lu grams of Friess recently when being interviewed by reporter of Xinhua News Agency too to in red to last great expectations at clean energy and cooperation prospect of fields in environment protecting mode. He says: “Denmark is the energy efficiency and neutral forerunner of carbon, and the development of China is very fast, add experience and speciality on the clean energy of Denmark, cooperative possession enormous potentiality and broad prospect in these fields in Denmark and China. ”

The network news of international energy: According to a report that comes from the Scottish government, probably there are 1/4 of the electric demands in Scotland it is to come from the regenerated energy and generate electricity at present.

The statistical data in 2009 released according to last week, in the electricity consumption of Scotland, the regenerated energy generates electricity and probably occupies 27% of the share. And Scottish regenerated energy generation probably accounts for 43% of British regenerated energy generation.

Scottish wind-power electricity generation, wave can generate electricity and generate electricity to increase with the solar energy by 37% in 2009, among them mainly wind energy generates electricity.

Scotland raise their regenerated energy power generating goal from 50% in 2020 to 80% recently. The capacity of power generating of regenerated energy while already building up and preparing in Scotland at present is 7GW, this impel Scotland can surmount regenerated energy generate electricity up to 31% of the tentative goals by 2011. In the regenerated energy of total 7GW generates electricity, wind-power electricity generation is probably 2.55GW, secondly it is the water and electricity, it is probably 1.5GW.

On December 20, Russian president Medway and Jeff began it to India’s two – day state visit. On the political platform of world of this year, India deserves to be called star light and glitters, because 5 permanent members of the United Nations Security Council all visit India in succession, the total trade contract signed is up to 50 billion dollars especially.

And this Medway and Jeff visits India, both sides have signed 30 cooperative agreements in fields such as military affairs, nuclear energy, medicine, information technology,etc.. Both sides hope to realize the goal that the bilateral volume of trade reach 20 billion dollars by 2015. The data of the Russian Embassy in India reveal, up to now, the bilateral volume of trade of Russia and India is 10 billion dollars.

An undoubted one is, the nuclear power will become cooperative keywords of two countries in the future. Because of the fast development with economy, Indian government plans to newly build 20 nuclear power stations, increase installed capacity of nuclear power of 60,000 megawatt by 2030, its market value is up to 150 billion dollars. As to this enormous market of nuclear power, big countries of nuclear power such as France, U.S.A.,etc. both want to open the gate and get a cup of custard, leaders such as U.S.A., France,etc. visit India this year, discuss nuclear cooperation inevitably too, Russia and India talk, put the nuclear power cooperation to the first place even more this time.

Wish to receive the introduction according to Indian foreign minister Kerry, in the field of civil nuclear energy, Indian atomic energy department and Russian national Atomic Energy corporation Rosatom Have signed a cooperation agreement on the development of nuclear reactor technology. Sergey, president of Rosatom, prolong in the base department say at least until place build 18 of nuclear reactor in India three future such as Russia to reporter, this excludes in the Nation of the south of India at present – -Thaimil receives the nuclear power station of nurse of Koola of construction of Nation of Germany, it is reported, this nuclear power station is expected to be on active service in the first quarter of 2011. Prolong in the base subject say, Indian leader has reaffirmed this time that will offer the plan that selects site for the fact that Russia builds the third nuclear power station in India.

As to the agreements of nuclear power and arms which India sign with Russia, Pakistani respect reacts strongly, Pakistani foreign minister’s spokesman Abdul and Baster says, these agreements may strengthen the unstability of South Asia area.

Since Russian period, Russia is the intimate cooperative partner of India, for a long time, Russia is the main arms source country of India, but, with the power of the position on the world arena of India, India hopes to reduce the reliance on Russia too at present. The cooperation of U.S.A. and India taking civil nuclear cooperation as sign is walking close, this makes Russia rather uneasy too.

Then, is Russia totally ready to enter the market of Indian nuclear power? If also there is worry at present, that is probably August of this year, a nuclear energy responsibility bill which the Indian parliament passes. This bill agreed to be open to private investor the market of Indian nuclear energy, but the nuclear accident presumed the compensation standard with very high upper limit at the same time: Once the nuclear accident happens, the compensation ceiling is up to 320 million dollars. The Indian finance and economics network Sify thinks, as to the nuclear energy responsibility bill, Russia has not been really ready yet, Russia fails to really meet the market of Indian nuclear power after this bill is issued too at present. Meanwhile, the fast neutron pile type of Russia will be also having competition from AP1000 of U.S.A. and European pressurized water reactor.

Want, launch the intersection of nuclear power and cooperation, the intersection of country and competition of Company, unavoidable and Japan, France, U.S.A.,etc. of Russia, with India. As to this, the says that the researcher of Indian energy security research institute fits east Cordeaux, in the following 15 years, India will become the main market of overseas nuclear power of Russia. Larry, former foreign minister of India, special Mansingh says, Russia will be a very important cooperative partner in India according to regular energy and unconventional energy.

And the news, in this talks, the Russia-Indian two countries still strengthen intergovernmental agreements of cooperative signing of the oil gas field, Indian Premier Singh says, this is an agreement reached through the fact that both sides make great efforts, this reflects the economic complementarity of the two countries too.

According to Russia ” businessman’s newspaper “, the special horse Sistema of state-run investment company west Sri Lankan of Russia With Indian National Oil Company ONGC Have signed a cooperative agreement. According to Reuter, the west special horse Company of Sri Lankan has already agreed to consider letting the Indian petroleum giant participate in the assorted oil company of Palestine, the west special horse Company of Sri Lankan has most shares of the assorted oil company of Palestine. Say in a statement which the west special horse Company of Sri Lankan issues at time when Russian president visits New Delhi, both sides still agree to consider strengthening the investment in the each other energy field in the future.

As to this, Britain ” Financial Times ” thinks, this measure of Indian National Oil Company is to indicate publicly India hopes to reduce the reliance on the petroleum of Middle East area. Indian National Oil Company have size 1 the intersection of petroleum and the intersection of event and 20% share, forest of Kazakhstan, Sa through the intersection of subsidiary and ONGC Videsh. And this cooperation between Russia and India has much benefits to west special horse Company of Sri Lankan, because this company manages telecommunications mainly, looking for the global cooperative partner in order to strengthen its expansion in the field of oil gas too at present, it is believed that the west special horse Company of Sri Lankan united by marriage with Indian National Oil Company expands an important step of its oil gas industry.

? ? The network news of international energy: ? Because Pakistan can’t supply power generating company with the sufficient petroleum, Pakistan’s electric shortage is up to 3000MW, this causes the time that the subregion loses electrical power to rise to 5-9 hours.

What received can believe news, Pakistani Utilities Electric Co. can’t totally satisfy power plant’s demands for fuel according to ” Pakistani observer “. Only there is 1500MW in the generation of power plant of public department, if the fuel gets China’s supply, its generation will increase to 2500MW.

The fuel used to generate electricity that PSO supplies is 16000 tons, the demand is 23000 tons by contrast.
