Adaptive current damping module for improved power converter control in wind turbine systems

Abstract:

Systems and methods for controlling a power converter in a wind turbine system are provided. The wind turbine system can include a generator and a power converter. The power converter can include a plurality of switching devices and a current damping module. A method can include determining, by a control device, a flux magnitude of an air-gap between a rotor and a stator in the generator. The method can further include determining, by the control device, an orientation adjustment reference signal for the current damping module based at least in part on the flux magnitude. The method can further include controlling, by the control device, the power converter based at least in part on the orientation adjustment reference signal.
