What is the working principle of wind electric power generation ?

Wind energy has a certain kinetic energy, and wind energy is converted into mechanical energy by a wind turbine, and the generator is driven to generate electricity. The working principle of wind electric power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation by the speed increaser to promote the generator to generate electricity. According to the current windmill technology, a wind speed of about 3 m/s can start generating electricity.

The working principle of wind electric power generation is very simple. The simplest wind turbine can be composed of two parts: the blade and the generator. The kinetic energy of the air flow acts on the impeller, converting the kinetic energy into mechanical energy, thereby pushing the blade to rotate. If the rotating shaft of the impeller is connected with the rotating shaft of the generator, the generator will be powered.
