The continuous increase in global energy consumption has made the global energy crisis increasingly apparent. Developing renewable energy to alleviate the energy crisis and achieve sustainable energy development has become a major measure for energy development in various countries around the world. Wind power has become an important direction for global energy development due to its huge reserves, renewable, widely distributed, and pollution-free characteristics worldwide. In recent years, the world's installed wind power capacity has grown at an average annual rate of approximately 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. As a new type of energy, wind energy has a low utilization efficiency, which has become a bottleneck restricting its development. Therefore, improving the utilization efficiency of wind energy is very important.
Wind power relies on wind turbines to convert wind energy into electrical energy. The wind turbine's rotor is composed of three blades made of fiberglass or nylon. The wind blows the wind wheel to rotate and converts the low-speed rotation on the wind turbine shaft (approximately 18-33 r/rain) into the high speed required by the generator (800r/rain or 1500 r/min) through a variable speed gearbox, which is transmitted to the generator shaft to rotate and generate electricity.
