Permanent magnet direct drive small wind turbines with unit reliable, simplify the structure, operation and low noise advantages of wind power into the area of today’s cutting-edge technology products.
Back in February 2008, China South Locomotive and Electric Corporation on joint Goldwind start joint R & D offshore wind power generation products. They have absorbed the mature 1.2 MW and 1.5 MW wind generators permanent magnet synchronous on the basis of merit, just 2 months time, completed the run with low speed, simple structure, small number of parts, reliability high, maintenance and other technical features of the 2.5 MW offshore wind turbine development, delivery Goldwind work into the test assembly.

China South Locomotive and Electric Company is the core component of our rail transportation equipment – traction motor and transformer technology leader. In 2004, the company and the Xinjiang Gold Wind Technology Co., Ltd. 形成 strategic cooperation partners, established the Chinese Wind Engineering Research Center Technical Yanjiuzhongxin electrical, and mass production has born out of 750KW, 800KW, 1.2MW and 1.5MW wind generator . Has become an annual output of 2,000 MW in China’s biggest wind turbine manufacturers.

According to the China South Locomotive and Electric company called: to the middle of this month, only a short period of four years, the company’s megawatt-class wind power generator production, from 50 to 380 units to 1,500 units to 2,000 units , to have scaled the four steps. This year will be delivered 60 sets of wind technology companies to gold, 600 will be delivered next year. These products have been successively Tongliao, Dabancheng, Dafeng, Jiangsu and other high-volume use of wind power.

China has rich wind energy resources offshore, offshore wind energy resources in 10 meters water depth of about 100 million kilowatts, 20 meters water depth of offshore wind energy turbines resources of approximately 300 million kilowatts, 30 meters water depth of offshore wind energy resources of approximately 490 million kilowatts, the amount of wind energy in China sea value is 3 times the land-based wind energy, has broad development prospect. Wind power has the characteristics of environmental pollution, a 2.5 wind turbine generator 21.9 million a year degrees, families can meet electricity 12166.

China’s first large offshore wind farm – 100 MW of Shanghai Donghai Bridge all set before offshore wind farm and power generation. 34 wind turbines large impeller rotation will be the East China Sea wind energy into electricity by undersea cable, pouring into the Shanghai power grid.

China’s first large offshore wind farms all the fans and power generation

BEIJING China’s first large offshore wind farm – 100 MW of Shanghai Donghai Bridge all set before offshore wind farm and power generation. 34  small wind turbines large impeller rotation, the East China Sea wind energy into electricity, through the submarine cable, pouring into the Shanghai power grid. Annual wind generators capacity is expected to reach 267 million kwh, which can meet more than 20 million Shanghai residents a year demand. Shanghai World Expo is also the first time to spend this new green energy.

My own design, built by the East China Sea Bridge wind farm of 34 3 MW wind turbine, with a total installed capacity of 102 MW, annual energy use of design hours 2624 hours, 267 million kwh in electricity access, with our fully self- intellectual property rights, the State Development and Reform Commission in May 2008 approved a large-scale offshore wind power project. Total investment of 2.365 billion yuan in the offshore wind farm east of Donghai Bridge in Shanghai, 1 to 4 km coastline south of the Pudong New Area of Shanghai from 8 to 13 km area. Where the average water depth of 10 meters, 90 meters above the sea surface height of the design average wind speed 8.4 m per second.

East China Sea Bridge wind farm development and construction projects to improve the self-China offshore wind power equipment wind power generator  manufacturing capacity, China has accumulated experience in offshore wind power construction and management and promote energy conservation, etc. Shanghai is of great significance. It is estimated that the East China Sea Bridge wind farm of 34 turbines and power generation, after all, compared with coal-fired power plants a year, saving 86,000 tons of standard coal, reduce emissions of carbon dioxide, 237,400 tons of greenhouse gases, energy saving efficiency significant.

It is learned that the East China Sea Bridge wind farm Phase II (100,000 kilowatts level) preliminary work has been approved by relevant departments, plans to start the second half. Phase II will provide unit capacity greater and more advanced technology demonstration platform provides fans. Shanghai also plans to build another four offshore wind farm: Fengxian 100,000 kilowatts, Pudong 400,000 kilowatts of two wind farms, preliminary work has started; Fengxian 300,000 kilowatts, Hengsha 200,000 kilowatts of two wind farms also done in the long-term planning. This four wind farm is completed, Shanghai’s total installed capacity of offshore wind power will reach 1.1 million kilowatts. In addition, a single blade 56.4 meters, the wind wheel diameter of 116 meters, sea fans, “Big Mac” – 3.6 megawatt wind turbines, recently re-equipped base in Shanghai Electric Harbor successful offline and will be realized in August and Network Operation. This is our most technologically advanced independent research and development, the largest wind turbine capacity from Shanghai Electric Wind Power Equipment Co., an independent research and development trial.

Shanghai New Energy and Industrial Development, as the leading one of the 3.6 megawatt offshore wind turbine, the overall level has reached the leading domestic. A single 3.6 MW offshore wind turbines per year out of 900 million kWh, saving about 3,150 tons of standard coal in the coal, are zero emissions. 3.6 MW offshore wind generating units with an open control system according to user needs, different wind modification; also use the remote monitoring, automatic fire protection system.

July 22, a lift up to 88 meter test tower, opened in Lake Science and Education Industrial Park. According to reports, the test tower to the top of the world’s leading equipment, household wind turbine. Taihu New Town Science and Education Industrial Park in the Zhongxiu Science Park, covers an area of 30,000 square meters, will become the world’s renewable energy wind power generation of new products, world-class elevator controller, physical network sensor system design, development, production and sales centers . Among them, Weber Wind Technology Co., Ltd. specializes in producing high-efficiency household wind generators system, all sold to European countries. Sino-US joint venture Zhongxiu Kang Dike Elevator Technology Co., Ltd., R & D high-speed elevators, high-speed elevator control system, key technology and equipment and technology, to develop precise control system in the domestic high-speed, high-speed elevator applications.

Since 2004, driven by national policy, China’s wind power industry with Chinese-style machine speed leaps and bounds. Up to now, the whole company at least 80 more than the size of most enterprises and capacity has expanded each year and for the fans now do not have to worry about sales. With the Chinese government made commitments to the world: for 2020, China’s non-fossil energy in the primary energy consumption ratio of 15% of GDP unit carbon emissions below 2005 levels by 40% -45%, wind machine wind generator manufacturers warm again one was excited. Needless to say, the wind power generator industry will flourish, but to make more smooth the road ahead is required to respond to these challenges well.
Difficult to balance the scale of production
The field of wind power are often full of optimism, as the country of seven million kilowatts of wind power base level determination, machine wind turbines  manufacturers generally follow the principle of the nearest building of production bases, the rapid expansion of production scale, a scale larger than general shops.
However, the expansion of the scale as the double-edged sword, if the wind power industry development as well as expected, the machine manufacturers can seize this rare opportunity, increase sales, large-scale benefits to enterprises. If the wind power industry in the situation of stagnation or economic crisis, a situation similar to production, the large-scale enterprises to become cumbersome, liquidity shortage will be inevitable.
What factors will affect the wind power turbines industry the scale of production?
Now, hard to bear the brunt of wind power. In accordance with the existing network architecture and load capacity, National Grid Electric Power Research Institute predicts that by 2020 wind power capacity of up to 1 million kilowatts of installed capacity of the national planning objective is 150 000 000 -2 100 million kilowatts, 1 / 3 or more grid capacity could not affect the wind farm owners for investment. When large-scale power generation groups meet the state’s non-hydroelectric renewable energy accounting for 8%, the expansion of installed capacity of power are gone, fans will demand the risk of stagnation.
Moreover, whether the continuation of state policy is also important factors. Policy support to a large extent, funding support, such as tax breaks, financial subsidies, land support. When our economic situation has continued to maintain growth when, Duiyu support wind power Chanye not a Wen Ti, and once Chuxianquanguo or the world economic situation, the situation down, small wind turbines industry Zijin there may be Ying Xiang Hui.
Representative from the world view of the country’s development process, policies continued support very few intermediate ups and downs will likely stage.
Overseas markets blocked
China’s  home wind turbines machine enterprises begin to consider a few years ago to open up overseas markets, but the actual situation is not optimistic. Goldwind Yu Yao, Director of Public Affairs, “China Energy Report,” told reporters: “We need to be addressed three questions: First, market access certification; Second, bank credit facilities. On overseas markets, especially European and American markets, banks in the import and export a very important role to play, many fans of the funds the buyer to purchase access to bank credit by the bank in order to ensure the safe use of funds, resources and assessment of Chinese fans will organize enterprise products, price, enterprise strength, credit so inspected; Third, politicians in Europe and America have a fear that low prices of Chinese products, taking into account the protection of the local vertical wind turbines manufacturing industry, will be more Chinese companies not only expect to sell their products on the market, more To do something in the local investment, particularly in the past two years by the financial crisis, this tendency will become more intense. ”
Three questions which are not easy to solve, and market access certification in China is difficult to have a say in the international arena; fans the quality of products and credit needs of the test of time; trade friction is a long topic.
China’s wind power equipment, mainly by building wind turbine generators farms to absorb the domestic, and overseas markets at present does not seem so urgent. However, there is indeed overseas markets higher profits and greater development space, and have to make up for the role of changes in the domestic market situation, so wind power business to expand overseas markets is a matter of time.
Grab market unit price of imports decreased
Of wind turbines compared with the foreign unit, the main competitive advantage is price. Foreign-funded enterprises in China’s market share continued to decline from 2007, in order to reverse this trend, many foreign enterprises have gradually decreased fan blower prices, and wind generators manufacturer domestic brands is gradually narrowing the gap. That the foreign fans before the price higher than the 20% -30% local product views are out of date, and now the price gap between 10% -20% of enterprises to China’s unprecedented fan pressure.
As the fans continued to decline in price in recent years, although prices are part of the space, and machine business can be passed on to the parts cost way to temporarily ease the company, but is difficult to predict how long it can persist.
Difficult to master core technologies
Most of China’s wind power machine with foreign companies through joint development or purchase of the drawings the way to develop. “Standing on the shoulders of giants” may be subject to the giant, independent innovation is easier said it is hard.
For example, the fan control system design has been the weak link in our fans, a larger percentage of imports, several self-developed products has yet to achieve good results. Fan control system to realize the task of not only fans of the highly automated control and power to the grid, but also must pass the appropriate control to achieve the maximum wind energy capture and load to a minimum. In addition, because wind turbines in China a growing portion of the grid, wind power generation grid compatibility problem of the poor gradually exposed and the user on the different winds, the interconnection between the different types of fans are also required higher and higher, the fan control system is also put forward new tasks.
Sophisticated control system similar to this technology will become a long-term fan technology shortcomings. In addition, professionals such as wind power generators , fans etc would influence the quality of China’s wind power machine business challenges, wind power machine industry will soon face the new market environment, plan ahead is essential.

With the rapid development of wind turbine, wind power generator can meet the special environmental requirements, resistance to twisting, cold resistance, salt spray, oil, UV resistant, soft, mobile features such as wind power cables will be the focus of the development of the next few years .

Stator with extra high voltage cables, round cable will replace the rectangular copper bars, can not have generators and network transformers, and thus significantly reduce the cost.

In accordance with the principles of optimal design, large motor stator slot is rectangular, tank coil or bar has chosen rectangular conductor of the electric field intensity distribution along the surrounding ranges, and the four corners of the Ministry of up to 9KW/mm, The four sides which has only 3KW/mm. This will result in a significant waste of insulating materials. The cable has a circular cross-section does not exist the problem, uniform electric field. Fundamentally eliminate the concentration field corner, insulation thickness of inequality and can not be thinning and so on. This reform can use the electric field from the 2.5KW/mm increased to 15KW/mm. This round cable used industrial mass production of cross-linked polyethylene insulated, low cost, while the voltage it can be up to 500KW, a number of factors affect the voltage selection, such as grid connection, local Tiaojie rules, the maximum surface wind output unit, to the site distance, the impact on the environment. Generator output voltage to the high level of the grid, no need for another step-up transformer and the network. Round for the wind generator does not need a cable for metal shielding, though they have the same insulating material and solid extrusion technology, is popular on the market with standard items.

Wind power in Finland, Denmark and other countries is very popular; western China is also strongly advocated. Efficient small-scale wind power generaotr system, but it is not only composed by a generator head, but a certain technology in the small  wind turbine + charger + digital inverter. Wind turbine by the nose, swivel, rear wing, leaf form. Each part of the very important functions of various parts: leaves used to receive through the nose into the wind power; tail so that leaves always opposite to the direction of the wind to get the most out of the wind; swivel head can rotate in order to achieve flexibility tail to adjust the direction of the function; head of the rotor is permanent magnet, the stator windings cutting magnetic lines to produce electricity.

Fluctuating wind power generation due to wind, so the output is 13 ~ 25V AC change, subject to the charger rectifier, battery charger store again, so that electricity generated by small wind turbines into chemical energy. Then protect the inverter circuit, the battery inside the AC 220V chemical energy into electricity, can guarantee the stability of use.

Usually people think that wind generators solely by the decision, always wanted to buy a bigger wind turbine, which is not correct. The current to the battery charging wind turbines only, the energy stored by the battery up, people eventually use electric power, size and battery size more closely. Power depends on the size of even the size of wind, not just the size of the power head. On the mainland, a small wind turbine will be more appropriate than large. Because it is easier to drive and a small amount of wind power generator, continuous small wind, strong wind better than the moment a large supply of energy. When no wind it can also be caused by normal use of wind power, that is a 300W wind turbine can also be a large battery and inverter with the use, access to 500W or 1000W power out even more.

Use of wind generators, wind energy is pouring into our family used to the standard electricity, the savings level is obvious, a family only 20 yuan a year of electricity cost of battery fluid. Now the wind turbine performance than a few years ago a great improvement, previously used only in a few remote areas, wind generators connected directly to power a 15W light bulb, one out of a dark and often damage the bulb. Now, advances in technology, advanced chargers, inverters, wind power as certain scientific and technological content of the small systems, and can under certain conditions, instead of the normal electricity. Mountain to the system can not be a perennial money-lights; highway signs used it to do the night lights; mountain children can study up under fluorescent lights; urban high-rise rooftop wind turbine can also be used, which not only save but also real Green Power. Domestic wind generators, not only to prevent blackouts, but also increase the zest for life. In the tourism area, border, school, military and even behind the mountain, wind turbine generator procurement is becoming a hot one. Radio fans could use their own technology in wind power for the mountain people service, people watch TV and lighting synchronized with the city, but also make their own enrichment work.

Under construction in the Jingan “gold star” business in Hong Kong, will be the first use of wind power generator in a Class A office buildings – 1788 International Centre, it is learned, 1788 International Center uses a combination of the world’s leading energy saving technology, are the first buildings in Puxi through the global common certification of the first LEED Gold office. Put into use in March 2010 after will be the “gold star” green “landmark.”
1788 International Center of “window wall” to replace the glass curtain wall, double glazed windows recessed in the aluminum window frames inside, and each window can open 70 degrees maximum, this design can save about 30% of the building air-conditioning energy. Group of rooftop wind turbines with 6, it generates the supply of building wind energy lighting used in public channels, each light that one can save 2 million yuan electricity. Building a capacity of 200 tons will be set up in the water tank to collect rain water, the small wind turbines central air-conditioning cooling tower condensing water for irrigation, building cleaning and cleaning floors of the toilet tank water washed it for Building a saving of 12 %.

May 18 started the first round of offshore wind power generator tender, two offshore wind power project located in the coastal Jiangsu Province, Sheyang 2, the installed capacity of 300,000 kilowatts; two “intertidal zone” project is located in Dafeng and Dongtai, The 200,000 kilowatts.
China Guangdong Nuclear Wind Power generator Co., Ltd., Assistant General Manager Lu Hao said that some investors may vote once for each project, it may be more than 40 batches. Each item does have more than 10 bids buyers. The above person said, involved more than 20 companies bidding.
Insider, and launched in June this year, “Western Province 6 280 MW photovoltaic project tender” different, offshore wind power tender and bidding to buy the Client must first sign a confidentiality agreement, in order to get the value of more than 20,000 yuan the tender documents, tender bidders handed deadline in early September.
Also imposes the tender the bidder must be an independent legal person, either individually cast, it can be of the Commonwealth. But no matter what form, the bidder must be a funded or funded Holdings (more than 50% equity stake) in the joint ventures. Researcher Liu Sheng Wang of China Merchants Securities, said Chinese companies bidding requirements may be related to “sea” is the special geographical attributes.
The tender is also another important restriction is that bidders must have completed or under construction, wind farms, and the capacity of these wind farms to be equal to or higher than the scale of the investment project. In short, the bidder needs to be experienced wind power turbines operators. This limitation may be a lot of interest in the wind, but no experience of private enterprise get in the door.
Fan manufacturers choose
China Guangdong Nuclear One insider says, offshore wind power unit is best to be bigger, “because the cost of offshore lifting and transport costs are high. Although a 3-megawatt turbines and two 1.5 MW of fan power the same amount, but the 3 MW of fan operation and maintenance costs much less than 1.5 megawatts. ”
Shanghai Electric Group Vice President, Shanghai Electric Power Group, told the newspaper, president arsenic trioxide, do the best maritime international major fan wind generators manufacturers are Siemens, domestic fans in this business just started, “In addition, this round of bidding also provides the sea, Fan manufacturers want to have (at sea) to run the fan performance, compliance with the requirements of wind power equipment company in the country should not be much. ”
Shanghai Electric Group, another senior, said the first batch of bidding on the wind power equipment factory are also provided, which have a 100 MW wind turbines station to run performance, while the type of fan participation in the tender, should also have a station in operation. In addition, the bidding model needs to be 2 MW (and above) models.
Arsenic trioxide, said Shanghai Electric developed the far the largest fan unit – 3.6 MW fan, the fan on May 20 this year, passed the FBI and the ground network of full load power test, in early August will be implemented and Network Operation in line with relevant regulations. The Goldwind, Sinovel and others have more than 2 MW fan products.

One side is the rising tide of new energy investments, while it is a massive clean energy grid can not be wasted; as a rich space for development of new industries in recent years has caused a lot of questions … …, experienced a growth spurt years China’s wind power generator industry, began to appear a lot of confusion and tangled, the development of China’s wind power is not winding path puzzle.
In 2005, “Renewable Energy Law” was promulgated specifically to support wind power and other new energy industries. In the supporting policies support large-scale wind power generators development in China started, and to cause raspberry wind speed became the world TV state.
Similar to other industries, China’s wind power development can not avoid refined to have contracted the development – Governance – further development of the industry with Chinese characteristics ills. In 2009 by the ministries as wind power industries with excess capacity, the public did have to wind power is “crazy” point of view to allocating public opinion.
However, wind power is really hopeless disease yet? Reporters interviewed on issues related to China’s wind power expert, honorary chairman of the China Electrotechnical Society Mr. Zhou Heliang.
Zhou Heliang first attributed to the current small wind turbines development in China a few prominent contradictions:
First, wind power is difficult
At present wind power has become China’s wind power industry, the outstanding bottleneck. Determine the characteristics of wind power turbines is difficult to maintain the stability of its load, but can not synchronize with the power load changes, there must be other wind power commitment to adapt to changes in load demands, to increase power generation capacity adjustment, peak shaving capability and storage capacity, which requires optimization of the power structure, increasing investment and operation of pumped storage units, to increase the scale of construction peaking power. “Therefore, the development of wind power development plan to enter a whole, Canada
Construction of large power input. ”
In addition, to strengthen the research and forecast wind. Now, the country has built 400 wind towers. “But this is not enough, the research on wind energy laws should be further strengthened,” Zhou Heliang that “to build wind power prediction and forecasting system, wind power and grid companies to promote cooperation and coordination.” In addition, Zhou Heliang stressed that ” countries to access power assessment, not evaluation capacity. Yinwei installed easy, and the net hard. “Once the Internet power to as targets, the State of all aspects of the unit to be an incentive to boost the enthusiasm, including the wind farm, grid companies, particular grid. “Because wind power, mainly rely on grid companies to promote.”
Wind energy resource-rich areas now, most of the local grid system is small, electric load Shao, pairs of wind power consumption is satisfied Nenglibuzu, which Kanchuwoguo cross-network interconnection small-scale, Li Yu wind power in a larger scope Xiao Na. To solve this problem, the key is to increase the intensity of cross-network construction.
Zhou Heliang that the development of wind power to the grid and network synchronization with both non-development, the formation of diversified, balanced development pattern. In the wind energy resource-rich areas, construction of wind power base, building a large network, but also small and medium sized wind farm construction according to local conditions, to meet the remote and inaccessible areas of the electricity demand.
Secondly, the whole plant overcapacity
At present, many domestic fans machine china wind generators  manufacturers, the National Family Style electric machine assembly has been hundreds, manufacturers, and the market share of 60% of the total concentrated in the gold wind, sharp and East China gas in the hands, the three-year domestic available production enterprises with more than 2 million kW, and the remaining 40% of the market share of family property to lower the machine nearly a hundred works by intense competition.
To prevent redundant construction, the Ministry of Industry in March 2010 issued a wind power equipment manufacturers access to draft standards to improve the access threshold for wind power equipment, reduce excess capacity. Meanwhile, National Grid is also studying the development of relevant technical standards and network specifications. In this regard, Zhou Heliang that reduce excess capacity should aim at capacity, more importantly, to improve equipment quality, performance, level of direction.
Third, the equipment reliability issues highlighted
Strong support in recent years in policy, through the introduction of technology, China has basically mastered the megawatt-class wind turbine manufacturing technology, has formed blades, gearboxes, generators and control systems and other major components of the wind power equipment industry chain, but Since most wind power company, heavy manufacturing, light innovation, re-introduction of light absorption, the key of wind power equipment and core technology subject to foreign, independent innovation capacity of wind power technology into weakness, equipment quality, especially the quality of key components Urgent increase. Coupled with the rapid development of China’s wind power industry, launched a large number of fans rushed the equipment from the research and development to the actual running time is shortened, so that lack of preparation as a result of R & D fan is running a series of problems emerged.
Zhou Heliang that equipment reliability issues will affect the development of large wind power in China worry that China’s wind power equipment manufacturers need to focus on wind power main and auxiliary machine optimization and matching, to improve equipment reliability to make a great effort.
Fourth, public technical service system lags behind
Years of wind power in the context of rapid growth, most businesses Jizhong the device Zhi Zao, Er Wind Power Industry R & D platform and public services Ti Xi Ji Shu Mei You  industry is far from the pace of development of effective production, and research integrated technology R & D system still in a primitive being. Zhou Heliang, said wind power industry, public technical service system is a national act, by the government to lead.
In this regard, Zhou Heliang made the following recommendations: improve the standard system (including the key components and common parts), perfect quality certification system, the motor must be load test, leaves must be static and dynamic fatigue test, must be analog converter test , simulation and real load test; establishment of the South, the North Wind national test, mandatory for new fans to live life test; set up research and innovation platform – National Wind Technology Center, to accelerate the process of absorption and innovation ; learn from the Netherlands kM mode, the key components of wind power generator to establish national testing center; establishment of a national monitoring center fan operation time to collect wind speed, temperature fluctuations, humidity, power failure, power consumption data; establishment of a national wind energy information center, complete information statistical system, the authority for issuing notice; the full development of wind power professionals, including wind power design, process and installation, commissioning, operation and management personnel at all levels of technology development, management, operations and senior skilled workers to address the talent shortage of wind power.
Fifth, the wind power technical services required to develop
“We now have a wind power industry, the obvious question, is the wind generators farm’s operation and management level is too low, mostly attention to wind power installed capacity building, the expense of running.” Zhou Heliang visited a number of wind farms, he found “To maintain, repair capability, or maintenance, management capabilities are not keep up.”
Zhou Heliang recommended to explore the formation of professional and technical services operation of wind power company, the establishment of regional wind power plant and wind farm maintenance parts library, the development of modern wind power technology services. This is similar to the field of real estate property management, specifically with professional property management companies provide the owners with a full range of social service.
Sixth, be careful to promote offshore wind power
Now, offshore wind power is becoming a new favorite in the field of wind power in China. Although offshore wind power with wind energy resources are very stable and do not take up land resources, the advantages of minimal environmental impact. However, compared to land-based wind power, the offshore wind farm building is not only large investment and high technical difficulty, but also faces the sea ice, a series of typhoons and the risks of uncontrollable factors.
“China’s first offshore wind development on the face of technology, equipment and project development experience, reliability constraints,” said Zhou Heliang develop offshore wind power in China, or novice, need to be treated with caution. In the conditions allow, you can give priority to the development from the load center near offshore wind resource conditions are particularly good demonstration project. At the same time, once decided to develop, enhance the development of an appropriate scale should be possible, using the country’s most mature technology and equipment. Offshore wind power investment is 2.5 times the land wind, and offshore wind power equipment maintenance costs high, thus requiring offshore wind power machine equipment must have high reliability to be guaranteed.
Zhou Heliang emphasized that windmill power as a new industry, will inevitably have some problems, but this is the industrial development process itself, the problem is the way forward in the conflict, because these problems must not be unworthy, the negative role in development of wind power and significance.
Zhou Heliang analysis, wind power industry also need 3 to 5 years to enter into maturity. Mature stage was marked by conflicts over access to basic solution, there is no obvious contradiction. “Another important indicator of the mature stage is a fan run time can be in more than 2000h,” Zhou Heliang, the “wind farm in the country is now about 1 / 4 of the wind turbine is idle, the utilization rate of less than ideal requirements. according to several typical wind farm is estimated that annual operating at 1800h fans around, only profit, loss of wind power can not always, or else there would be no development potential. ”
“These are all a process, these five years, we have solved MW of wind power the problem from scratch,” Zhou Heliang finally stressed that “the next stage, we will address the optimization of wind power turbines development. As long as we gradually and steady development of wind power, to avoid big ups and downs, wind power industry will weather a new strategy to achieving the national goal of energy saving a major force.
