Wind turbine equipment into China-made top priority China's
wind power equipment market share by most of the possession of foreign manufacturers, China's
wind power industry dependent on foreign technology, in particular, a number of core equipment to rely on imports, the realization of wind power equipment in China has become a top priority.
According to the Danish wind advisory body BTM "international wind energy development - global market trends in 2006" predicted that China in 2011 the total wind power installed capacity will reach 17,400,000 kilowatts. In the industry predicted that by 2020 China's total wind power installed capacity is expected to reach 30,000,000 kilowatts -5000. This means that in the future for a long time, China's wind power equipment demand to remain strong growth. In addition, energy shortages and rising oil prices, continued to increase pressure on environmental protection, national industrial policy with the strong support, will be to promote wind power industry continued growth.
However, China's
wind generators development because of various factors, slightly less than its potential. At present, the megawatt-class wind turbine capacity has become the mainstream of the international market, and our independent megawatt-class manufacturing capacity of wind power unit of the few manufacturers; core technology and independent innovation capability is still relatively low, the production of key parts and components Supply capacity is weak.
In order to encourage domestic
wind genrators equipment manufacturers to increase R & D efforts to promote wind power industry bigger and stronger, the Ministry of Finance recently announced that domestic enterprises will have to develop, manufacture wind power generating units and the import of critical components, raw materials paid by the Import tariffs and import-related value-added tax policies to implement front-end retreat. Industry experts believe that it will be to a certain extent, to stimulate domestic manufacturers of wind power enthusiasm for research and development, so that the wind power industry into the track of healthy development.
Lack of core technology into the development bottleneck
"This is a sunrise industry, we are very optimistic about the development of wind power." Enter the wind power equipment manufacturers in the field less than two years of a wind power companies said: "Now that our technologies are bought, why we do not Can do? "
The person in charge, then exposed China's wind power industry's embarrassment: wind power and broad prospects, the Government's strong support, but eating a piece of "cake" of the domestic wind power equipment manufacturers is the lack of core technology.
It is understood that our country from the 1970s to develop large-scale wind power unit, in 1997 only to the countries in the "wind", with the support of scientific research from the market. However, due to a lack of basic research and the accumulation of human resources and other reasons, our own research and development of wind power capacity of a serious shortage of wind power equipment design and manufacturing level is relatively backward, on the whole, is still in the track and the introduction of foreign advanced technology stage.
Although China has mastered the following 750 kilowatt wind turbine capacity of the whole and parts of the design and manufacturing technology to achieve the production, but this is equivalent to the international community in the mid-1990s. Most of China's wind power equipment manufacturing enterprises remained in the low-end equipment design and manufacturing level, and the domestic level VSCF MW generating units are still developing, megawatt-class blade, gearbox and the generator is only small batch production. "At present, China's wind power unit in the control systems, bearings, fan blades, gear box, and other aspects of the existence of large parts of the contradictions between supply and demand. Although the entire wind power industry developed rapidly, but wind power equipment manufacturers is an obvious capacity Insufficient, particularly in the most-megawatt capacity of wind power unit, electronic control system and bearing almost no production capacity. "CCID Consulting Industry Research Center senior energy consultant, said Lu Kun, the whole, domestic wind power technology research and development still weak , The wind power industry chain development imperfect production capacity of wind power equipment, large-scale wind power equipment is heavily dependent on imports, which are constraining China's wind power industry development.

Moreover, with the domestic unit growth in travel time by the lack of experience brought about by quality problems have begun to emerge as a result of design flaws led to the gear box of tooth fracture, as a result of high levels of hydrogen-containing materials led to the rupture of the main shaft and so on. At the same time, the industry has been existing in the "light weight machine parts" of the existing wind power led to the irrational product mix is continuing.
"At present, China's wind power equipment market share by most of the possession of foreign manufacturers, China's wind power industry dependent on foreign technology, in particular, a number of core equipment to rely on imports, the realization of wind power equipment in China has become a top priority." Chinese Wind Energy Association Shi Pengfei, vice chairman, said, "In addition, wind power serious shortage of technical personnel, the introduction of rapid technological capacity to form after the after-sale maintenance problems are quite severe."
Policy to promote their own R & D
Ministry of Finance on the implementation of wind power equipment manufacturers import tariffs on parts and components and import value-added front-end or back of the policy will promote the wind power industry to a higher level across. "An industry source said.
"In the wind power equipment in the field, and we are still a wide gap between the developed countries. Megawatts in installed capacity level has become a mainstream market, domestic enterprises must grasp of the world development trend of wind power equipment, with international practice." Shi Pengfei, introduced Said that at present, the international wind power equipment manufacturing enterprises progressive globalization, large-scale and integration. "This may be the preferential tax policy on domestic wind power equipment -

At present, a number of wind power equipment manufacturers have begun to intervene in megawatt-class wind turbine research and development, production, megawatt-class wind turbine manufacturers go a long way in the spring up all over the domestic trend. Does this mean that China's wind power equipment manufacturers in this area has the strength to the world's advanced level?
Huarui Wind Power Technology Co., Ltd., a insiders said, "when Boeing would also like to enter the wind power unit in the field of manufacturing, technical clearance, however, finally gave up, it can be said that the development of megawatt-class wind power unit is not difficult to Asia In the manufacture of aircraft. "
According to the industry, domestic wind turbine manufacturing technology to rely on the vast majority of foreign countries, there are three models: One is the introduction of foreign technology and design drawings, or with foreign design companies design, manufacture and production at home, the wind Production technology 1.5 MW wind power unit is jointly developed with foreign countries; Second, the foreign purchase of a mature wind power technology in China for the production license, such as the East's 1.5-megawatt steam turbine unit; Third, a joint venture with foreign companies, foreign Mature technology in domestic production, such as aerospace NCR be able to produce 1.5 megawatts of wind power unit. Shenyang University of Technology, only the 1.5-megawatt wind power unit is on its own R & D production.
"Domestic wind power equipment manufacturers rely on foreign technology start-megawatt-class wind turbine capacity, exposing domestic manufacturers lack the ability to research and development." Lu Kun said that as the domestic wind power equipment for the core technology of foreign dependence, not only have to pay a The use of pen technology costs, causing corporate profits decline, and megawatt-class wind turbine capacity of many of the difficult parts production.
According to the disclosure of scientific and technological wind data, analysts predict gold wind 1.5 MW wind turbine technology group at 21.66 percent gross margin. Gordon said shares of electricity, the company producing the 2-megawatt wind turbine output to reach about 140-150 of Taiwan in order to achieve break-even.
Shi Pengfei of the view that the wind power unit in deplorable conditions for 20 years running, high technical requirements. To produce a good performance, high reliability and large installed capacity of wind power unit must have a process of accumulation of experience, and have to go through wind power to run the pilot test alone is clearly not to buy foreign technology, enterprises need to have their own R & D实力.
National Development and Reform Commission, Energy Research Institute, the development of renewable energy Wang Zhongying, director of the Center pointed out that "wind power technology to enhance China's basic research capabilities, as soon as possible to establish state-level wind power technology research and development institutions, coordinate the technical resources available to carry out the basic public - Technology research and development, should establish and improve the wind power equipment, technical standards, testing and certification system to promote technological progress of wind power, wind power to ensure product quality, reduce the cost of the promotion; should build large-scale wind energy laboratory facilities to support new products and test Certification testing; in view of the majority of key technology companies is still in the digestion and absorption of sound or stage should be set up to promote independent innovation and industrial development incentive policy
