ABSTRACT:
A wind turbine hybrid braking system is presented. The system includes a generator coupled to a main shaft of the wind turbine for generating and transmitting power. A mechanical brake is coupled to the main shaft for applying reaction torque upon braking of the wind turbine. The system further includes an electrical braking circuit coupled to the generator for acting in conjunction with the mechanical brake and dissipating active power via controlled switching.
