摘要: A method for controlling the operation of a wind turbine may generally include monitoring a current yaw position of a nacelle of the wind turbine, wherein the current yaw position is located within one of a plurality of yaw sectors defined for the nacelle. In addition, the method may include monitoring a wind-dependent parameter of the wind turbine and determining a variance of the wind-dependent parameter over time, wherein the variance is indicative of variations in a wind parameter associated with the wind turbine. Moreover, the method may include determining at least one curtailed operating setpoint for the wind turbine when the variance exceeds a predetermined variance threshold, wherein the curtailed operating setpoint(s) is determined based at least in part on historical wind data for the yaw sector associated with the current yaw position.

摘要: The present disclosure is directed to a method for reducing loads of a wind turbine. The method includes monitoring, via a turbine controller, a rotor blade of the wind turbine for faults. If a fault is detected, the method includes determining an operational status of the wind turbine. If a predetermined operational status is present at the same time the fault is present, the method also include actively yawing a nacelle of the wind turbine away from an incoming wind direction until either the fault is corrected or cleared and/or the operational status changes.
