Analysis of methods to improve the efficiency of wind power generation

The continuous increase in global energy consumption has made the energy crisis more apparent worldwide.


The continuous increase in global energy consumption has made the energy crisis more apparent worldwide. Developing renewable energy to alleviate the energy crisis and achieve sustainable energy development has become a major measure for energy development in countries around the world. Wind energy has become an important direction for global energy development due to its enormous reserves, renewable, widely distributed, and pollution-free characteristics. In recent years, the world's wind power installed capacity has been growing at an average annual rate of about 30%. As a major consumer of fossil fuels in the world, China is facing a serious environmental pollution crisis caused by fossil fuel power generation. Wind energy, as a new type of energy, has become a bottleneck in its development due to its low utilization efficiency. Therefore, improving the utilization efficiency of wind energy is very important.

Wind power generation relies on wind turbines to convert wind energy into electrical energy. The rotor of a wind turbine consists of three blades made of fiberglass or nylon. The wind blows the wind turbine to rotate, and through the variable speed gearbox, the low-speed rotation on the wind turbine shaft (about 18-33 r/rain) is converted into the high-speed rotation required by the generator (800 r/rain or 1500 r/min), which is transmitted to the generator shaft to rotate and generate electricity.
