A wind turbine is a device that uses wind energy to drive blades to rotate, thereby generating electricity. Wind generator is generally composed of wind turbines, generators, tails, towers, speed-limiting safety mechanisms and energy storage devices. The principle of a wind turbine is relatively simple: the wind wheel rotates under the action of the wind, and converts the kinetic energy of the wind into the mechanical energy of the wind turbine shaft. The generator is driven by a wind turbine shaft to generate electricity.
