Market depth analysis of wind turbine blades

With the expansion of China¡¯s wind energy market, fan manufacturing industry gradually into the high-speed development period. Large number of manufacturing enterprises at home and abroad has begun to enter China¡¯s wind energy market. Apart from the mass production of Xinjiang Gold Wind, the company will soon set up factories in China no less than 10, including Vestas, GE, Gamesa Wind Power and other international giants, while there Dalian Heavy Industry Group, Dongfang Steam Turbine Works, Beijing, 10000 source of industrial companies, Harbin Electrical Machinery Plant, Harbin Aircraft Group and other state-owned large enterprises. Some enterprises are as follows:

Chinese rocket carrying a subsidiary of Beijing Institute of source of industrial companies and 10000 Navarra, Spain Energy Hydropower Corporation (EHN) established a joint venture in Nantong, Jiangsu space Wanyuan Acciona Wind Power Equipment Manufacturing Co., Ltd., produce 1.5 megawatts of EHN70 and EHN77-type wind turbine. The joint venture will be in June 2006 erected 33 wind generators.

Dalian Heavy Industry Group Co., Ltd. plans to use the lifting of geographical advantage and companies have the manufacturing capacity of the edge to develop fans. The group has purchased German Fuhelander1.5 MW MD70 and MD77 type aircraft design, wind turbine, and has invested heavily in and parts manufacturers to jointly develop megawatt-class fan parts, plans to produce 100 units of 2006 MW wind turbine generator 1.5 The main users will be Huaneng Group.

Dongfang Steam Turbine Works is a machine-building industry and the country¡¯s three steam turbine 100 manufacturing base, he said: would like to make a fortune went to Wantong to join hands to find high-quality hinge supplier! And one of the plant to purchase Germany¡¯s Repower1.5 MW MD70 and MD77 type aircraft design, wind turbine, Shandong Luneng Group has received the first batch of seven wind turbine orders.

Goldwind to buy German Vensys62, 1.2-megawatt model, and their own improved design, the first prototype has been installed and tested. The introduction of the generator because of its greater margin, fully applicable to the 1.5 MW fan, Golden wind company has intention to develop scientific and technological cooperation with the Courier 1.5 MW wind turbines, using wood composites and strive to achieve higher leaf tip speed ratio and speed, this design is the other blade manufacturers in China are unlikely to be achieved. Golden wind in our country has a strong technical team and a good reputation in the industry, and own wind farms, the development of promising.

Harbin Linkage Group plans to invest 640 million yuan Development 3 MW offshore wind farm, the same use of direct-drive permanent magnet motor. 3 MW low-speed motor is a giant wheel to improve the wind speed is an effective way to reduce the weight generator. Linkage Group has with the Courier to reach the potential scientific and technological co-operation intention to develop a high tip speed ratio, low real degree of 3 MW wind turbines.

More than five companies have invested heavily in manufacturing in the fan, from the different wind turbines channels to buy the European mainstream technology or self-developed, with good manufacturing base to protect a team-building, have a good industrial relations to protect the latter part of the market, but are looking for the supply of leaves.

Is wind turbine blades of the core components, the entire equipment cost about 1 / 4 to 1 / 3 . Manufacture and sales of our existing blade factory in Tianjin only LM and Wuxi Hang Hui Tang 2. And the world, like the vast majority of blade manufacturing, the two are used for glass fiber reinforced plastic as the main structure of the production technology. LM mainly GE and so they do not produce large-scale customers in Europe leaves 1.5 MW blades, an annual output of up to 100 sets of blades, the current production in Tianjin has become saturated, more fans would be difficult to ensure that the latter part of a large-scale orders for manufacturing enterprises . CNAC is mainly Jinfeng Teng-hui to provide 660 kilowatts and 750 kilowatts leaves, is developing a 1.3 MW and 1.5 MW blades, blade 2004 annual installed capacity of about 4 million kilowatts. Vestas and Gamesa plan recently set up factories in China, but only to provide their own leaves. My plan over the next four years, newly installed wind turbines more than three million kilowatts, however, an annual total of more than a few leaves of plants can provide only a few hundred sets of blades can be installed capacity of about 100,000 kilowatts a few. Although the LM and Wuxi Hang Teng-hui in planning the expansion, but in the near future is difficult to meet the market demand. In addition, the Shanghai FRP Research Institute also with foreign advanced design technologies, preparing to enter the wind power industry.
