Abstract
A system and method are provided for controlling a wind turbine. Accordingly, a controller of the wind turbine detects a loss of traction of the slip coupling based on a difference between data indicative of a rotor operating parameter and data indicative of a generator operating parameter. The controller then determines an angle of slip corresponding to the loss of traction as a function of the difference. Based, at least partially on the angle of slip, a degradation value for the slip coupling is determined. A control action is implemented based on the degradation value.

A method for controlling a wind turbine, the wind turbine having a drivetrain comprising a rotor, having one or more rotor blades mounted thereto, rotatably coupled to a generator via a slip coupling, the method comprising:
- detecting, via a controller, a loss of traction of the slip coupling based on a difference between data indicative of a rotor operating parameter and data indicative of a generator operating parameter;
- determining, via the controller, an angle of slip corresponding to the loss of traction as a function of the difference;
- determining a degradation value for the slip coupling corresponding, at least partially, to the angle of slip;
- and
- implementing a control action based on the degradation value.
A system for controlling a wind turbine, the system comprising:
- a rotor having one or more rotor blades mounted thereto;
- a generator rotatably coupled to the rotor via a slip coupling;
- at least one operational sensor operably coupled to the rotor and configured to monitor a rotor operating parameter of the rotor in operation;
- and
- a controller communicatively coupled to the generator and the at least one operational sensor, the controller comprising at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
- detecting a loss of traction of the slip coupling based on a difference between data indicative of a rotor operating parameter and data indicative of a generator operating parameter;
- integrating the difference over a sampling interval to determine an angle of slip corresponding to the loss of traction;
- determining a degradation value for the slip coupling corresponding, at least partially, to the angle of slip;
- and
- implementing a control action based on the degradation value.
