Abstract
A system for operating a wind turbine during a curtailment operation is described. The wind turbine includes a generator and a wind turbine rotor having at least one rotor blade. The wind turbine also includes a drive train that includes at least one shaft coupled to the wind turbine rotor and configured to drive the generator. The system includes a control system configured to increase a speed of rotation of the rotor beyond an optimum rated speed during the curtailment operation of the wind turbine, and an extraction device configured to extract inertial energy stored in the drive train upon release of the curtailment operation.

A system for operating a wind turbine during a curtailment operation, the wind turbine comprising a generator and a wind turbine rotor having at least one rotor blade, the wind turbine also comprising a drive train that includes at least one shaft coupled to the wind turbine rotor and configured to drive the generator, said system comprising:
- a control system configured to increase a speed of rotation of the wind turbine rotor beyond an optimum rated speed during the curtailment operation of the wind turbine;
- and,
- an extraction device configured to extract inertial energy stored in the drive train upon release of the curtailment operation.
A method for operating a wind turbine during curtailment of the wind turbine, the wind turbine comprising a generator and a rotor having at least one rotor blade, the wind turbine also comprising a drive train that includes at least one shaft coupled to the rotor and configured to drive the generator, said method comprising:
- operatively coupling a control system to the wind turbine, the control system configured to adjust wind turbine operation to facilitate increasing a speed of rotation of the rotor during curtailment of the wind turbine;
- and,
- operatively coupling an extraction device to the generator, the extraction device configured to extract inertial energy stored in the drive train upon release of the curtailment.
