A brake system (52) for controlling a rotational speed of a drivetrain (40) for a wind turbine (10) is provided. The drivetrain is coupled to a rotor shaft (36) and a generator rotor shaft (38). The brake system includes a mechanical brake operatively coupled to the drivetrain, the mechanical brake including a brake caliper (56) and a brake disc (54) coupled to the drivetrain, a sensor (68) configured to detect a parameter of the wind turbine, and a controller (30) configured to actuate the brake caliper to apply a braking force on the brake disc, the controller configured to control the mechanical brake based on the parameter to selectively adjust a brake torque (206) generated by the braking force. |
