9.5m/S 1.0MW Wind Power Turbine Generator

 

 

 

We convert the kinetic energy of the wind into mechanical energy, and then convert the mechanical energy into electrical energy. This is wind power. The principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to promote the generator to generate electricity. The equipment required for wind power generation is called a wind turbine. This kind of wind turbine can be divided into three parts: wind wheel (including tail rudder), generator and iron tower.
