摘要： A system and method for reducing oscillation loads of a wind turbine induced by high turbulence and/or combined with other environmental conditions are provided. The method includes determining at least one wind parameter at the wind turbine; monitoring an operating condition of the wind turbine; determining, by a processor, a variance of at least one of the monitored operating condition or a plurality of the wind parameters, wherein the variance is indicative of an oscillation occurring at one or more wind turbine components; determining, by a processor, an operating set point based on the variance; and, operating the wind turbine based on the operating set point when the variance indicates that the oscillation has a frequency within a certain frequency band so as to modify the frequency, wherein the modified frequency is outside of the frequency band and reduces oscillation loads occurring at the one or more wind turbine components.

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： A method of operating a wind turbine is provided. The wind turbine includes a rotor that is rotatably coupled to a generator that is positioned within a nacelle. The rotor includes one or more rotor blades that are coupled to a hub. The method includes transmitting, from a first sensor to a control system, at least a first monitoring signal indicative of a first wind condition at a first distance from the wind turbine. A second sensor transmits at least a second monitoring signal that is indicative of a second wind condition at a second distance from the wind turbine that is longer than the first distance to the control system. The control system calculates a wind turbine operating command based at least in part on the first monitoring signal and the second monitoring signal. One or more wind turbine components are operated based on the calculated wind turbine operating command.

摘要： A wind turbine blade has a suction side shell member and a pressure side shell member. The shell members are joined along a leading and trailing edge from a root to a tip of the blade and defining an internal cavity of the blade. A pressure sensor is configured on at least one of the suction or pressure side shell members. The pressure sensor further includes a body mounted to an inner surface of the respective shell member within the internal cavity. A sensing element has a first side exposed to external air pressure through a passage in the respective shell member, and an opposite second side exposed to a reference pressure. Control circuitry within the body generates a variable output signal as a function of a pressure differential between the external air pressure and reference pressure experienced by the sensing element.
