CA 2628383

A method of reducing a structural unbalance in a wind turbine rotor (3) with pitch control and a control device for performing the method are provided. The method comprises the steps of: - detecting a magnitude of the structural unbalance and its phase in relation the rotor's azimuth (.theta.) on the basis of a measurement of the rotor's azimuth (.theta.) and a measurement of the rotor speed or the generator speed (.omega.); - establishing individual pitch angle offsets for each blade (5, 7, 9) of the rotor (3) on the basis of the magnitude and the phase; and - adding the individual pitch angle offsets to the respective pitch angles of the blades (5, 7, 9) of the rotor (3).
