A method for testing a mechanical brake of a wind rotor shaft of a wind turbine, comprising:
- applying a predetermined desired brake torque to the mechanical brake;
- applying a predetermined drive torque to the wind rotor shaft by a motor;
- measuring a parameter indicative the rotational speed of the wind rotor shaft;
- and,
- determining the performance of the mechanical brake based on the measured value of the parameter.
A method for testing a mechanical brake of a drive train of a wind turbine comprising:
- applying a predetermined rotational speed to a wind rotor shaft of the drive train by a motor;
- applying a predetermined desired brake torque to the mechanical brake;
- maintaining the rotational speed of the drive train at the predetermined rotational speed;
- and,
- determining the actual brake torque.
A system for testing a mechanical brake of a drive train of a wind turbine, wherein the drive train is connected to a motor, comprising:
- a first control device adapted to set a motor parameter, such that the motor rotates and maintains a wind rotor shaft of the drive train with a predetermined rotational speed;
- a second control device adapted to set a predetermined desired brake torque to the mechanical brake;
- and,
- a torque determination device for determining the actual brake torque.
