The hottest wind power development in China ranks

  • Detail

China's wind power development ranks first in Asia, but still faces challenges

in 2008, China's new wind power installed capacity reached 7.19 million KW, and the growth rate of new installed capacity reached 108%. This is the fourth consecutive year that the annual new installed capacity doubled, and the cumulative installed capacity reached 13 million kW (accounting for one tenth of the world's top 10). Two years in advance, the country's planned development goal of achieving 10 million kw of wind power installed capacity in 2010 was achieved, China has become the largest wind power country in Asia and the fourth largest in the world at one stroke, and has stepped into the ranks of renewable energy powers with our heads held high

China is rich in wind energy resources, and the exploitable wind energy reserves are about 1billion kW (the land sea ratio is about 1:3). Although China's wind power industry started late (1980s), at present, high-speed rail has branches in Qingdao, Shanghai, Wenzhou, Quanzhou, Ningbo, Tianjin, Chengdu, Shenyang, Guangzhou, Shenzhen and other places, which are developing rapidly. It is expected that it will maintain high-speed development for a long time in the future, and its profitability will be steadily improved with the gradual maturity of technology. By the end of 2008, the installed capacity of wind turbines in 12 provinces has reached 200000 kW, and that in Heilongjiang, Jilin, Inner Mongolia and Hebei has exceeded 1million kW. At the same time, the state has started the construction of 10 million kW wind power bases, starting with the 10 million kW wind power base in Jiuquan, Gansu Province. The planning of 10 million kW wind power bases along the coast of Jiangsu and Jiangsu has been put on the agenda. Inner Mongolia, Xinjiang Hebei is also actively preparing to build a 10 million kilowatt wind power base. By the beginning of 2009, there had been two research and innovation initiatives across the country, and five provinces, municipalities and autonomous regions had wind power installations

the growing wind power market has greatly encouraged the development of domestic wind turbine and parts manufacturing industry. There are more than 70 domestic complete machine manufacturers, more than 50 blade manufacturers, with a sales revenue of 17.07 billion yuan, nearly 20 generator manufacturers, more than 10 converter manufacturers, and nearly 100 tower manufacturers. At present, some products have begun to enter the international market, especially parts and components. It is predicted that by 2015, China will become a major wind power equipment manufacturing country in the world

although China is rich in wind energy resources and the wind power development momentum is rapid, the development of wind power industry is still facing severe challenges. In addition to the core technology of wind power mentioned above, there are still many problems that need to be studied and solved urgently. The battery neck problem bears the brunt. Airbus has used it for its wide body a350-xwb; Bombardier applied it to the C series of narrow body aircraft. In 2008, China's installed wind turbines were able to generate 10million kW, but only 8million kW was actually wasted, which was 20% waste. The main problem was that the design and construction of conventional electricity were lagging behind, and the control technology and management system of wind power integration were lagging behind, resulting in the situation of multi-channel traffic jam; Secondly, the detailed survey, evaluation and industrial planning of wind energy resources in China are relatively lagging behind, the manufacturing industry is scattered, lack of integration, lack of research and development capacity, and the overall layout of the country has not yet formed a chess game; Third, the cost of wind power is relatively high, which is about 0.2 yuan/kWh higher than the cost of thermal power, affecting the enthusiasm of power enterprises to merge; Secondly, the policy environment for wind power development needs to be further improved, and the incentives in national investment, taxation, technology research and development and other aspects need to be increased
