    摘要: Method of operating a wind power plant including the steps of: operating the wind power plant at an current parameter schedule (Pcurrent(v)) performing a wind prediction of wind data (Vw) for a time frame (ΔT) extending to a future time T, determining a desired fatigue load level (Fdesired) of a wind power plant component at the future time T, and during operation of said wind power plant generating an updated parameter schedule (Pdesired(v)) to provide the desired fatigue load level (Fdesired) at time T if exposed to the predicted wind conditions (Vw(t)) during said time frame (ΔT)

    摘要: A method of controlling a wind turbine rotor blade, the blade comprising a pitch axis about which the blade can be pitched, and a flap movable to alter the aerodynamic profile of the blade, the method comprising the steps of: providing a pitch angle request (θ) to a pitch actuator; determining an initial flap angle request (β_flap); providing a decoupled flap angle request (β) to a flap actuator; herein the decoupled flap angle request (β) is calculated from the pitch angle request (θ) and the initial flap angle request (β_flap) such that the decoupled flap angle (β) provided to the flap actuator does not counteract the pitch angle request (θ); and pitching the blade according to the pitch angle request (θ) and moving the flap according to the decoupled flap angle request (β).
