摘要： The present disclosure is directed to a method for determining an estimated rotor shaft position of a rotor shaft of a wind turbine. The method includes generating, with a rotor shaft position sensor, a measured rotor shaft position signal associated with a measured rotor shaft position of the rotor shaft. 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.

摘要： 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.

摘要： A method for identifying a blade run-away condition in the event of a pitch system failure of a rotor blade of a wind turbine includes determining, via one or more sensors, an actual rotor loading of the wind turbine. The method also includes determining, via a turbine controller, an estimated rotor loading of the wind turbine based on at least one of one or more operating conditions of the wind turbine or one or more wind conditions of the wind turbine. Further, the method includes determining a difference between the actual rotor loading and the estimated rotor loading. The method also includes determining whether the blade run-away condition is present based on the difference. The method may also include implementing a corrective action that mitigates loads caused by the blade run-away condition.

摘要： A method for reducing loads of a wind turbine includes determining a wind speed at the wind turbine. Further, the method includes determining an operational state of the wind turbine. The method also includes determining whether a rotor of the wind turbine is imbalanced beyond a predetermined threshold when the operational state corresponds to a predetermined operational state as a rotor imbalance beyond the predetermined threshold is indicative of a pitch fault in one or more of the rotor blades. In addition, the method includes yawing a nacelle of the wind turbine to a predetermined angular position when the wind speed exceeds a predetermined speed threshold and the rotor is imbalanced beyond the predetermined threshold.

摘要： 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.

摘要： 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.
