What is the principle of windmill power generation?

1. Windmill power generation principle: Wind turbines are mainly composed of wind turbines and generators. Wind turbines convert horizontally flowing wind energy into mechanical energy, and generators convert mechanical energy into electrical energy.

2. China is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 654.38+0 billion kW, of which the land wind energy reserves are about 253 million kW (calculated by the height data above the ground 10m) and the offshore wind energy reserves are about 750 million kW, accounting for 654.38+0 billion kW. By the end of 2003, the national installed capacity was about 567 million kilowatts.

Wind is one of the pollution-free energy sources. And it is inexhaustible. For coastal islands, grassland and pastoral areas, mountainous areas and plateau areas with water and oil shortage and inconvenient transportation, it is very suitable and promising to use wind power according to local conditions. Offshore wind power is an important field of renewable energy development, an important force to promote wind power technology progress and industrial upgrading, and an important measure to promote energy structure adjustment. China is rich in offshore wind energy resources, so accelerating the construction of offshore wind power projects is of great significance for promoting coastal areas to control atmospheric smog, adjust energy structure and transform economic development mode.

The attempt to use wind power to generate electricity began as early as the early 20th century. In the 1930s, Denmark, Sweden, the Soviet Union and the United States successfully developed some small wind power generation devices by applying the rotor technology of aviation industry. This kind? Small wind turbines are widely used in windy islands and remote villages, and their power cost is much lower than that of small internal combustion engines. But at that time, the power generation was low, mostly below 5 kilowatts.
