Abstract
Provided is a wind turbine including an active yaw system realized to maintain an upwind orientation of the wind turbine aerodynamic rotor during safe operating conditions, which active yaw system includes a number of yaw drive units, and wherein a yaw drive unit includes a negative brake; a principal power supply configured to supply power to the active yaw system during normal operation of the wind turbine; and a dedicated negative brake reserve power supply configured to supply power to the negative brakes in the event of a grid disconnect. A method of operating such a wind turbine is also provided.
Claims14
A wind turbine comprising:
- an active yaw system configured to maintain an upwind orientation of a wind turbine aerodynamic rotor during safe operating conditions, the active yaw system comprising a plurality of yaw drive units, wherein a yaw drive unit comprises a negative brake;
- a principal power supply configured to supply power to the active yaw system during normal operation of the wind turbine;
- and
- a dedicated negative brake reserve power supply configured to supply power to the negative brakes in an event of a grid disconnect.
