Use the strategic vision of wind power production – wind power equipment, new en
Present, the community that the rapid development of wind power, mainly in the following two points: First, power grid construction building faster than the wind power grid bottlenecks increase; Secondly, too much wind power equipment manufacturers, there is excess capacity Tendency .
Present, the community that the rapid development of wind power, mainly in the following two points: first, Power supply Building faster than power grid construction, wind power and network bottlenecks increase; Secondly, too much wind power equipment manufacturers, there is excess capacity Tendency.
As a random and intermittent wind power characteristics, development and construction of wind power in China is relatively concentrated, a single wind farm installed capacity of large scale projects, and most end or weak areas in the network, large-scale wind power development on the local network security operation, scheduling, Power supply Structure configuration, power supply and a coordinated operation, power consumption and outgoing and so will have a greater impact, therefore, large-scale wind power, there is still difficult to access network.
If the whole environment and resources to analyze the situation, they concluded that wind power development is not excessive, but the network is lagging behind. All the wind power system, certification, standards are still imperfect. Further speed up construction of power grids, from policy co-ordination of interests, should be the focus of the next step.
From a macro perspective, in 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 energy storage technology, nationwide power dispatch will be gradually realized, consumers will be satisfied that this part of the wind power is not a problem.
Second question, China's wind Motor Group manufacturing and more dispersed, small scale, and to introduce and assimilate foreign technology-based, independent R & D less, the community said the wind power machine manufacturing company has reached more than 70, showing as willing to enter wind power manufacturing industry, many companies, but really have the ability to machine manufacturing company is still one of the few.
2008, the Dalian sharp Goldwind, Dongfang Steam Turbine annual production of all three companies reached over 1 million kilowatts, fan manufacturers are the first echelon; in the second tier of the fan manufacturer in Zhejiang arrival , Shanghai Electric , Ming Yang, Xiang electricity, annual output in the 10 to 25 million kilowatts. In addition, there are five companies had just started a small batch production, annual output of less than 10 million kilowatts. Other Enterprises, is still in prototype manufacturing or even just "thinking" stage of manufacture. Therefore, more than 70 the number of enterprises are not the same as equipment capacity.
Considered after 2010, China's annual new wind power installed capacity of 10 million kilowatts will be about 80% if the localization of equipment, the domestic market demand will reach eight million kilowatts. With the new countries Energy Policy of gradual release, the international market for fans of the domestic market demand will be 3 to 4 times. 2010, the international wind power equipment for the 50 million kilowatts in demand, if our equipment can account for 20% of the market, when the annual demand will reach 10 million kilowatts.
Thus, by 2010, China's annual production of wind power facilities should be around 20 million kilowatts, taking into account the capacity utilization of 70%, the formation of the total capacity of 30 million kilowatts is not not too.
Industry competitive in the final analysis is the competition among enterprises, the Chinese wind power equipment industry, the scale first and western countries to achieve the same order of magnitude, while upgrading the capacity to further improve the level of autonomy of wind power equipment and technical content, training international competitiveness. Therefore, judge whether the excess production capacity, to look into the global market, China's wind power equipment company in the future, is "going out", to the international market.
Currently the world's largest power equipment companies top 5 family traditions are Danish Vestas, the United States, GE, Spain's Gamesa, India's Suzlon and Germany's Nordex, the five companies in 2008 annual output of 5.58 million kilowatts, respectively, 5.24 million kilowatts, 337 kilowatts, and 2.53 million kilowatts and 107 kilowatts. According to this order of magnitude calculation, annual output of China's machine manufacturing enterprises the highest Dalian sharp, needs to be expanded to 4 times the capacity and Vestas matched.
