A method of operating a wind turbine comprising a rotor, a multi winding generator having a plurality of independent sets of control windings and a plurality of independent power electronic converters for controlling each set of control windings independently, the method comprising in a normal operation mode, the plurality of power electronic converters controlling the sets of control windings in substantially the same way, whereas in a positioning mode for positioning a rotor of a wind turbine in one of one or more predetermined angular positions, one of the independent power electronic converters controlling its corresponding set of control windings in a substantially different manner than at least one other independent power electric converter. The invention further relates to a wind turbine adapted to work in at least two different operating modes. |
