China's southeast coastal areas are rich in wind energy resources, with an average annual wind speed of 4 m/s. The township industries in these areas are developing rapidly, with large electricity consumption and poor conventional energy, and some places connected to the power grid are also seriously short of electricity. In order to meet the needs of low-lift and large-flow water lifting operations such as farmland irrigation, aquaculture and salt making in salt fields, local users have been using some low-lift wind-driven water lifting devices. For example, Putian, Fujian uses wind power to extract water to make salt, Tianjin suburb uses wind power to remove salt to raise seedlings, and xintai city, Shandong Province uses pneumatic air pump to irrigate farmland. , and achieved certain economic benefits. Popularization and application of wind-driven water pumping units in the above areas is of great significance to the development of agriculture, fishery and sideline production. On the other hand, the inland areas with good wind energy resources in China, such as northern Inner Mongolia, Gansu and Qinghai, have an average annual wind speed of 4~6 m/s and a cumulative wind speed of 3~20 m/s of 4,000 ~ 5,000 h/year. This is a vast grassland special zone, with scattered population and difficult power grid access. Using deep well wind-driven water pumping unit to provide drinking water for herdsmen and livestock or irrigate small grassland has obvious social benefits for improving the living and production conditions of local herdsmen. In addition, Gansu, northern Xinjiang and the lower reaches of Songhua River are also rich in wind energy, which is suitable for developing wind power to lift water.

Since the early 1980s, China has taken small-scale wind power generation as one of the measures to realize rural electrification, mainly researching, developing and demonstrating the application of small-scale rechargeable wind turbines used by farmers. At present, the technology of units below 1 kW has matured and been widely popularized, forming an annual production capacity of 1 10,000 units. In the past 10 years, 5000~8000 sets were sold in China every year, and more than 100 sets were exported abroad. At present, small wind turbines of 100, 150, 200, 300, 500W and 1, 2, 5 and 10 kW can be produced in batches, with an annual production capacity of over 30,000 units and the maximum sales volume of100. In remote areas with no power grid, about 600,000 residents use wind energy to realize electrification. Up to 1999, China has produced 185700 small wind turbines, ranking first in the world.

The research and manufacture of large-scale wind turbines in China is accelerating. Yi Tuo Manufacturing Wind Power Equipment Co., Ltd., a joint venture between China Yi Tuo Group Co., Ltd. and Spanish power company MADE Renewable Energy Company, and Xi 'an Wade Wind Power Equipment Co., Ltd., a joint venture between Xi 'an Aeroengine Company and NORDEX Company of Germany, have produced 660 kW and 600 kW 1 main generator sets respectively, which have been installed in Yingkou Wind Farm in Liaoning Province for grid-connected power generation. The localization rate of these two units reached 40%. In addition, Zhejiang Dayun Wind Power Equipment Factory produced four 250 kW wind turbines on the basis of producing 200 kW wind turbines, which were installed in Nan 'ao Wind Farm in Guangdong. This is the best wind turbine with independent intellectual property rights in China.

The number of wind farms is increasing, and the installed capacity is increasing. From the construction history of wind farms in China, 1986 After the first wind farm funded by the Ministry of Aviation and the Shandong Provincial Planning Commission was built in Rongcheng, Shandong Province, wind turbines were introduced from all over the country to build wind farms, and the installed capacity increased year by year. 1990 cumulative installed capacity of 4000 kW, maximum single machine capacity of 200 kW；; 1993 cumulative installed capacity 14500 kW, with a maximum single machine of 500kw; 1995 cumulative installed capacity of 3 .75kW；; By the end of 1997, there were 433 wind farms installed in China, with a capacity of 166700 kW and a maximum single machine of 600 kW. 1998 has a total installed capacity of 224,000 kilowatts; 1999 reached 262,400 kilowatts.

The unit capacity of wind turbines is increasing year by year. There are mainly two kinds of domestic units installed in wind farms: one is a scientific research prototype or several units produced in the later stage, which need to be improved due to technical and quality problems; The other is to cooperate with foreign manufacturers, and some parts can basically run normally with domestic substitutes. Most imported units are mature commercial units with high reliability. There are two types of this device: variable pitch adjustment type and fixed pitch stall adjustment type. Before 1996, the single machine capacity was 150~300 kW. Later, the main installed unit was 600 kW.
