Background

A wind power generator is a device that converts wind energy into electric energy. It generally includes wind wheels, rotors, generators, and control systems. When the wind wheel is pushed to rotate by wind, the rotor drives the generator to generate electric energy. The wind driven generator can be installed in a wind farm on land or at sea, and generates electricity by using natural wind energy. As a clean energy device, the wind driven generator has the characteristics of reproducibility and environmental protection, and is valued and applied by more and more countries and regions. Wind power generation has become one of the important renewable energy sources worldwide through continued technological improvements and industrial developments.
