China’s wind power generation and application of the current situation and prospects
As environmental issues become increasingly prominent, gradually strained energy supply, wind power as a clean renewable energy generating methods have been more and more people all over the world welcomed and valued. At the same time, wind power and new energy power generation technology is the most mature and the largest developed one of the conditions of the wind power generation. Therefore, in recent years, China’s wind power generation has also been the cause of the development soon.
1 China’s wind energy resources
Wind energy resources is due to the formation of the Earth’s surface atmospheric flow of a kinetic energy resources in general, characterized by the ground near the lower wind speed, wind energy will be small; and from the ground the greater the higher the wind speed, the wind also greater, which in the estimation of wind energy resources, is one of the key factors height. In this paper, and 10m from the high wind estimates.
Because China is a vast country, a long coastline with rich wind resources, but the complexity of terrain conditions, the wind energy resources is not evenly distributed. According to Chinese Academy of Meteorological Sciences more than 900 weather stations across the country is estimated that land-based wind energy resource reserves of 3.226 billion Theory kw, wind energy resources can be developed reserves of 253 million kw, mainly concentrated in the northern regions, including Inner Mongolia, Gansu, Xinjiang, Heilongjiang, Jilin, Liaoning, Qinghai, Tibet, and Hebei provinces, autonomous regions. Wind energy resource-rich coastal areas and islands, its development is about 1000 million kw, are mainly distributed in Liaoning, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi and Hainan provinces, cities and districts. However, these northern provinces, autonomous regions and as a result of flat, easily accessible, it is conducive to building a connected large-scale wind farm, for example, Dabancheng wind farm in Xinjiang and Inner Mongolia Huitengxile, such as wind farms.
2 of the development of wind power and status
China’s wind power is in the 20th century, late 50’s research and experimental work, when in Jilin, Liaoning, Xinjiang and other provinces, autonomous regions to build capacity in small 10kw wind farm, but subsequently at a standstill. The 20th century after the mid-70s in the world under the influence of the energy crisis, especially in rural and pastoral areas, islands and other pressing local needs for electricity, driven by China in some areas and departments of the wind power research, pilot and promote the use of give attention and support, but at this stage, the wind power equipment operation are independent. Until 1986, built in Shandong Rongcheng and China’s first wind farm network to run after the grid from wind farm construction operation into the exploration and demonstration phase, but is characterized by the capacity of both the size and small stand-alone. To have been built in 1990 and four-grid wind power, with a total installed capacity of 4.215mw, its largest stand-alone capacity of 200kw. On this basis, the wind power generation since 1991 has gradually started to enter the promotion phase, to 1995, the country has become to build five wind power grid model, the total installed capacity of 36.1mw, the largest stand-alone capacity of 500kw. After 1996, wind power has entered a stage of expanding the scale of construction, which is characterized by the scale and installed capacity of wind farms are larger, the largest stand-alone capacity of 1300kw. From 1996 to the end of 2002, China’s total installed capacity of wind power has reached 470mw
