China And Healthy Development Of Wind Power Equipment Manufacturing Industry Should Take Two
With the wind power industry in China in recent years
, the rapid development of wind power equipment manufacturing sector over-investment and the herd phenomenon phenomenon. In this connection, the State Development and Reform Commission issued "on the inhibition of overcapacity in some industries and duplication to guide the healthy development of industry, a number of views."
Wind power in China to achieve healthy development of equipment manufacturing industry should grasp the good in both directions. First, we must increase independent innovation, the company bigger and stronger, increase market competitiveness; 2 to increase the "going out" efforts to actively participate in international market competition, greater and more extensive development of survival and development.
Wind power equipment manufacturing industry is not pessimistic about the prospects
Data show that, in China's wind turbine manufacturing machine has more than 80, but there are many companies ready access to them. 2010 China's wind energy production capacity more than 20 million kilowatts, while the wind power installed capacity of about 1,000 million kilowatts.
On the current data, China's wind power equipment, especially the fans really excess capacity signs. However, from a development perspective, the development of China's wind power industry has great potential, great space. Wind power equipment manufacturing industry in particular, the development prospects of fans may not be as pessimistic as most people think.
2008 China's total installed generating capacity of nearly 800 million kilowatts, while only 10 million kilowatts of wind power, less than 1% of them. By 2020, China's wind power installed capacity will reach 100 million kilowatts, of the total electricity installed capacity will reach 1.5 billion kilowatts of wind power in the ratio of the power network will reach 6%. Then, with the smart grid and storage technology, nationwide power dispatch will be gradually realized, will be completely resolved in Inner Mongolia and Gansu in Northwest small loads, large amount of wind power online, send difficulties in practical problems, to achieve the full acquisition of wind power. Is huge potential for wind power industry.
Domestic fan manufacturers can be divided into three "echelon." Gold Wind Science and Technology, Dalian sharp, Oriental Steam three companies 2008 annual output was 100 million kw, is the first echelon; Zhejiang Province arrived in Shanghai Electric , Hunan Electric, China's aerospace companies such as the annual output of 10 000 sources in 10 to 250,000 kilowatts, is the second echelon; Another five companies are beginning to small batch production, annual output of less than 10 kilowatts, can be grouped into the third echelon.
Other companies actually manufactured at the prototype or even just "thinking" stage of manufacture. Therefore, 80 more than the fan manufacturer only figures which can not be equated with production capacity of equipment. China's wind turbine manufacturing industry currently the biggest problem is the large number of small scale, lack of independent technology development efforts, especially in machine manufacturing capacity truly a small number of enterprises.
Enhance independent innovation capability is the key
Constraints of wind power equipment manufacturing industry in China and healthy development of the most difficult situation, R & D capability of independent innovation is weak, many of the technical need to rely on foreign R & D institutions to achieve. Embodied in the overall design of large wind turbines and poor load calculation, control systems, Generator , Gear boxes, Bearing Poor design and production capacity. Meanwhile, China's manufacturing industrial base is relatively weak, fan bearings, control system Parts Also need to be imported from abroad.
Face of increasingly fierce competition in the market, the Chinese wind power equipment manufacturing industry has been aware of the "Independent innovation, research and development high-end product" is the key survival and development. In recent years, Goldwind, China Aerospace 10,000 sources such as wind power equipment company representatives to further increase the capacity of independent innovation, continue to improve the competitiveness of core technology.
Million of China's space launch vehicle technology of Chinese Academy of source as a subsidiary, from 1995, independent research and development 600 kW variable pitch wind Generator Technology, developed with independent intellectual property rights WD646 type 600KW wind turbine pitch; in 2003, when the composition of MW wind turbines for the wind power mainstream world, the China Aerospace International Strategy by Cooperation A way to quickly digest and master the most advanced level of international megawatt-class fan technology; 2006 joint venture with Spanish company produced 1,500 kilowatts AW1500 type VSCF wind turbines off the assembly line, and in that time to achieve mass production, respectively Zhangbei, Rudong, Jiangsu, Zhejiang, China Cixi so many wind farms in use, availability reached 98%.
