Observation on China's wind power industry: half is sea water and half is flame

China's wind power generation has developed rapidly

from July 8 to 10, 2009, the Sixth Asian Wind Energy Conference and international wind energy equipment exhibition was held in Beijing, and 445 enterprises from 22 countries and regions exhibited the latest products and technologies

at this meeting, the government, relevant experts and even representatives of wind power equipment manufacturers shared a common feeling: after experiencing the stage of leapfrog development, China's wind power equipment investment has shown an overheated momentum

the wind power industry has achieved leapfrog development

"under the background of the international financial crisis, China built 1.34 million kw of wind turbines from January to May 2009, showing a positive growth. The high growth rate of wind power equipment is not only much higher than that of other equipment, but also much higher than the development rate of international wind power." At the beginning of the wind power equipment manufacturing conference, Zhang Xiangmu, director of the equipment industry department of the Ministry of industry and information technology, announced the brilliant achievements of wind power equipment in the first half of 2009

at the meeting on the same day, Gao Hu, deputy director of the Energy Research Institute/renewable energy development center of the national development and Reform Commission, said that it is estimated that by 2020, China's installed capacity of wind energy is expected to exceed 100million kW, and will become the world's largest country in wind energy development at that time. In the "renewable energy medium and long term development plan" issued by the national development and Reform Commission in 2007, the long-term plan for the installed capacity of wind power in 2020 is still 30million kW. With the strong support of the government, China's wind power is ushering in greater development opportunities

data shows that the introduction of a series of industrial support policies such as the renewable energy law has promoted the rapid development of China's wind power industry. The total installed capacity of wind power in China was 1.26 million kW in 2005 and 2.6 million KW by the end of 2006. By the end of 2007, the total installed capacity was 5.9 million KW, an increase of 126% over 2006. In 2007, 3.3 million kw of new wind turbines were added, which was more than the total of the past 21 years, and was 20% more than the total, achieving the original target of 2 to reduce the conversion rate of China's new material technology achievements by 5 million kW in 2010. By 2008, China's installed capacity was about 12.153 million KW, with a cumulative increase of 106%

"the doubling of wind farms in the megawatt level for two consecutive years fully shows that China's wind power construction has entered the track of leapfrog development since 2005, and has now become the world's second largest wind power market after the United States. Even so, the overall development of China's wind power market is not high." Shi Pengfei, vice chairman of the wind energy professional committee of the China Renewable Energy Society, pointed out in an interview

Shi Pengfei said that in general, China has great potential for developing wind energy, with a total of 700million to 1.2 billion kw on land and at sea. By 2008, the installed capacity was only about 1% of the exploitable capacity. In the future energy structure, wind power can become an important part

UHV can effectively improve wind power transmission capacity

Tian Jun, regional and sustainable development consultant of the Asian Development Bank, was the second to speak at the meeting

after reviewing China's efforts to develop wind power and actively respond to the problem of global warming, Tian Jun stressed that the development of wind power in China is very different from that in Europe and the United States. China's wind power resources are far away from the load center, mostly in the terminal position of power, and the special geographical distribution of resources has brought great difficulties to the entry of wind power in China

Tian Jun judged that the development of wind power in China no longer depends on the development of China's manufacturing industry in the previous two years, but on the development of electricity. Tian Jun thus concluded that from a large-scale perspective, China must take the road of adding UHV to wind power to realize long-distance transmission of wind power; From a small scale, China must pay attention to small-scale decentralized users and develop wind power equipment suitable for their use

Gao Hu supported Tian Jun's judgment in his speech. Gao Hu believes that Chinese style is classified according to control methods: 1. Manual control and microcomputer servo control experimental machines; The distribution of energy presents the characteristics of "one line": one mainly refers to the three northern regions of China - the vast areas of northeast, North China and northwest, and the first line refers to the eastern coastal area represented by Jiangsu, which focuses on the production of high viscosity akulon film sea. According to the development plan formed by the national development and Reform Commission, China will carry out centralized development and construction in Inner Mongolia, Xinjiang, Gansu, Jilin, Hebei, Jiangsu and other places, so as to form seven ten million kW wind power bases, and most of these areas are just the weak links of electricity

problems such as insufficient power construction and merger technology caused by historical debt have led to only 80million kW of China's 120million kW installed capacity being connected to electricity in 2008, and nearly 1/3 of wind power equipment is idle or semi idle

the turnaround is gradually coming with the large-scale construction of UHV power in China

on January 16, 2009, China's first UHV AC test demonstration project was fully completed. At the same time, the Sichuan Shanghai ± 800 kV HVDC demonstration project is under intense construction, and the curtain of UHV construction in China is being fully opened. According to the relevant plans of the State Power Corporation of China, it is estimated that from 2009 to 2010, the investment in UHV will reach about 83 billion yuan, including 57billion yuan in UHV AC and 26billion yuan in UHV DC. By the early stage of the 12th Five Year Plan, the "two vertical and two horizontal" UHV backbone power will be initially built

at the beginning of July this year, Liu Zhenya, general manager of the State Power Corporation, said that wind power is a clean energy, which is strongly supported by the State Power Corporation. He hoped that everyone would emancipate their minds and work together to promote the sound and rapid development of the new energy industry. On the same day, Liu Zhenya also inspected a station site of the future Ximeng Shanghai West high voltage transmission and transformation project in Inner Mongolia. The feasibility study of the project has begun in March. Zhao Shuanglian, vice chairman of Inner Mongolia Autonomous Region, made it clear that if the project can be started, it will greatly improve the power transmission capacity of eastern Mongolia, promote the intensive development of coal resources and wind resources, and drive the coordinated development of regional economy
