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.
Claims18
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,
- wherein detecting the loss of traction of the slip coupling further comprises:
- filtering the data indicative of the rotor operating parameter and the data indicative of the generator operating parameter, wherein filtering the data precludes an inclusion of at least one known parameter deviation from the determination of the difference between the data indicative of the rotor operating parameter and the data indicative of the generator operating parameter, the at least one known parameter deviation resulting from a cause not associated with the loss of traction of the slip coupling.
A system for controlling a wind turbine, the wind turbine having a rotor comprising one or more rotor blades mounted thereto and a generator rotatably coupled to the rotor via a slip coupling, the system comprising:
- 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 the 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,
- wherein detecting the loss of traction of the slip coupling further comprises:
- filtering the data indicative of the rotor operating parameter and the data indicative of the generator operating parameter via a low-pass filter, wherein filtering the data precludes an inclusion of at least one known parameter deviation from the determination of the difference between the data indicative of the rotor operating parameter and the data indicative of the generator operating parameter.
