Abstract: A method for preventing catastrophic damage in a drivetrain of a wind turbine includes receiving, via a controller, a speed measurement of the generator of the drivetrain. The method also includes determining an electrical torque of a generator of the drivetrain of the wind turbine. The method further includes estimating, via the controller, a mechanical torque of the rotor as a function of at least one of the electrical torque and the speed measurement of the generator. Further, the method includes comparing, via the controller, the estimated mechanical torque to an implausible torque threshold, wherein torque values above the implausible torque threshold speed values greater that the implausible speed threshold. Moreover, the method includes implementing, via the controller, a control action for the wind turbine when the estimated mechanical torque exceeds the implausible torque threshold.

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.

Abstract: The present subject matter is directed to a system and method for improving speed control of a pitch drive system of a wind turbine. In one embodiment, the pitch drive system includes a direct current (DC) motor having an armature and a series-field winding, a battery assembly having a positive terminal and a negative terminal, and a current-controlling device configured in series between the positive terminal of the battery assembly and the series-field winding. The battery assembly is configured to supply power to the pitch drive system and the current-controlling device is configured to supply current to the series-field winding so as to ensure a field flux does not equal zero. Thus, the current-controlling device has the effect of limiting the maximum speed of the DC motor.
