Abstract
Systems, methods, and computer program products for controlling a yaw system of a wind turbine. The yaw system includes mechanical brakes that provide a first amount of braking torque when closed. The yaw system is configured to transition from a yawing state to a parked by brake state by closing mechanical brakes in a first subset of the mechanical brakes and opening each mechanical brake in a second subset of the mechanical brakes. The second subset provides a second amount of braking torque that is less than the first amount of braking torque. In response to detecting a rotation of the nacelle while in the parked by brake state, the yaw system is configured to transition from the parked by brake state to a parked by motor state in which yaw drives are activated to provide a counter acting torque in opposition to the detected rotation of the nacelle.
