The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity. Simply put, wind power generation is the process of converting wind energy into mechanical energy and then converting mechanical energy into electrical energy. Wind power industry is one of the emerging industries in China. Driven by the policy and market demand, the national wind power industry has achieved rapid development and become an important part of China's new energy system.
Wind is a kind of pollution-free energy, which is very environmentally friendly and can generate a lot of electricity, so more and more countries pay more attention to wind power generation. China is also gradually developing the wind power industry in the western region. In the future, with the maturity of wind power generation technology, more wind energy resources will be developed and utilized.
Current situation of wind power generation in China;
China is rich in wind energy resources, and the total amount of wind energy resources that can be developed and utilized in China is 250 million kilowatts. Southeast coast, Shandong-Liaoning coast and its islands, northern Inner Mongolia, northern Xinjiang, Gansu and other areas are rich in wind energy resources, with an annual average wind speed of 26m/s and an effective wind energy density of ≥200w/㎡, which has good development and utilization conditions.
Develop small and medium-sized independent wind power systems in remote areas with abundant wind power resources and no electricity shortage in China to solve the domestic electricity consumption and some production electricity consumption in these areas; In the south where wind power resources are abundant and the power grid is accessible, we should focus on developing large-scale grid-connected wind power systems to supplement and partially replace conventional energy sources and improve local environmental quality.
