Principle of operation of the wind turbine. When the wind blows through the turbine. The kinetic energy of the wind Making the rotating blades of the turbine. And a mechanical power out. The mechanical energy from the rotation axis of the wind turbine is converted to electrical energy. The generator is connected to the axis of rotation of the wind turbine. Supplying electricity through electrical control systems. And power supply into the system. The amount of electricity produced is dependent on the speed of the wind. The length of the blades And the installation of wind turbines.
