Abstract: The invention relates to a method for operating a wind turbine. The method comprises monitoring a wind turbine signal for detection of an over voltage of the grid and upon detection of the over voltage, initiate an over-modulation mode wherein the grid side converter is operated with a modulation index being increased in an over-modulation range at least during a sub-period of the over-modulation mode, and upon the detection of the operational condition, initiate a DC-voltage adjustment mode wherein the DC voltage of the DC link is decreased from a second voltage level towards a first voltage level at least during a sub-period of the DC-voltage adjustment mode.
