A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine is generally composed of components such as the wind wheel, generator (including the device), reversing device (tail fin), tower, speed-limiting safety mechanism and energy storage device.
The working principle of a wind turbine is relatively simple. Under the action of wind force, the wind wheel rotates, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
