Abstract
The present invention relates to a method for balancing a wind turbine. The method includes the steps of a) measuring at least one property that is dependent on a motor workload of at least one yaw motor 52 of a soft yaw system 5 during a period of time, b) calculating an unbalance based on the measurement of step a), c) determining a pitch offset angle for at least one turbine blade 41 based on the calculation of step b), and d) changing the pitch of the at least one turbine blade according to the pitch offset angle of step c) for decreasing the unbalance. The present invention also relates to a system for balancing a wind turbine.
