METHOD FOR OPERATING A WIND TURBINE CONNECTED TO A UTILITY GRID DURING UTILITY GRID DISTURBANCE, WIND TURBINE AND WIND PARK

摘要

The invention relates to a method for operating a wind turbine connected to a utility grid during a utility grid disturbance. The method comprises the steps of controlling active current in dependency of the frequency deviation from a reference frequency, and controlling reactive current in dependency of the voltage deviation from a reference voltage. The invention also relates to a wind turbine and wind park.
