Zusammenfassung:	The present disclosure is directed to a system and method for operating a wind turbine in response to one or more grid events or faults occurring in a power grid. The method includes monitoring, via one or more sensors, a grid voltage of the power grid so as to detect one or more grid events occurring in the power grid. In response to detecting at least one grid event, a controller determines an operating catch point for the wind turbine component and applies a torque demand to the wind turbine component when the operating catch point is reached. Further, the torque demand may be based on an initial torque demand acting on the wind turbine component before the one or more grid events occurred. Therefore, applying the torque demand to the wind turbine component is configured to reduce oscillations occurring in the component caused by one or more grid faults.
