ABSTRACT:
The invention relates to methods for controlling a wind turbine connected to the utility grid by detecting status of the utility grid, and controlling one or more rotor blades and/or emitted power to the grid in returning to the operational wind turbine settings of normal grid mode. The invention also relates to a wind turbine and a wind park comprising at least two wind turbines.
