  • YAW SYSTEM WITH YAW CONTROL BASED ON CONTROL SIGNAL
    Publication number: 20230228244
    Abstract: A controller for the yaw function is coupled with a yaw system for controlling the operation of yaw motors in the yaw function of a wind turbine. A control signal is provided to the controller that is reflective of a grid condition of an electric grid. The control signal is evaluated, and the controller selectively delays the yaw function based upon the control signal. In another embodiment, the yaw system includes brakes for the yaw motors that are coupled with an independent power supply. The controller selectively delays the yaw function if the brake power supply is not operational.
