The method also includes generating, with a plurality of accelerometers positioned in an axisymmetric arrangement, a plurality of rotor hub acceleration signals associated with a plurality of rotor hub accelerations of a rotor hub coupled to the rotor shaft. The method further includes determining, with a controller, a phase adjustment based on one of the plurality of rotor hub acceleration signals or a predetermined correction value. Furthermore, the method includes adjusting, with the controller, the measured rotor shaft position by the phase adjustment to determine the estimated rotor shaft position of the rotor.

    Abstract: The present subject matter is directed to a system and method for dynamically controlling a wind turbine. The method includes operating the wind turbine based on a thrust set point and a speed set point. A next step includes determining a desired change in actual speed of the wind turbine in response to control actuations starting from an instantaneous operating point. The method also includes determining a desired change in thrust of the wind turbine in response to control actuations starting from the instantaneous operating point. Next, the method determines at least one parameter set point that achieves the desired change in speed and the desired change in thrust and controls the wind turbine based on the parameter set point so as to maintain the actual thrust and the actual speed of the wind turbine within a certain tolerance of the thrust set point and the speed set point, thereby regulating loads acting on the wind turbine while simultaneously maintaining optimal or near optimal power output.

    Abstract: A method for monitoring and controlling a wind turbine to minimize rotor blade damage includes receiving sensor data from one or more sensors indicative of at least one blade parameter of the rotor blade over a predetermined time period. The method also includes trending the sensor data for the predetermined time period with respect to at least one wind parameter. Further, the method includes determining at least one characteristic of the trended sensor data. Moreover, the method includes comparing the at least one characteristic of the trended sensor data to an operating threshold. In addition, the method includes implementing a control action if the comparison of the at least one characteristic of the trended sensor data and the operating threshold indicates blade damage is occurring or is likely to occur.

    Abstract: The present disclosure is directed to a system for controlling a pitch angle of a rotor blade of a wind turbine. The system includes a pitch adjustment mechanism for adjusting the pitch angle of the rotor blade and a controller communicatively coupled to the pitch adjustment mechanism. The controller is configured to determine a wind asymmetry parameter based on an operating parameter of the wind turbine. The controller is also configured to determine first and second signal components of the wind asymmetry parameter, which are respectively indicative of a maximum load on a first wind turbine component and fatigue on a second wind turbine component. The controller is also configured to calculate a wear parameter based on the first and second signal components and initiate an adjustment of the pitch angle of the rotor blade based on the wear parameter.
