Abstract
The present disclosure is directed to a method of compensating for rotor imbalance of a wind turbine. The method includes receiving, via a processor of a controller of the wind turbine, a signal associated with an acceleration of a tower and a signal associated with a position of a rotor. The method also includes estimating a rotor imbalance based on the signal associated with the acceleration of the tower. The method also includes estimating, via an adaptive filter algorithm, components of the rotor imbalance relative to the rotor position. The method also includes calculating a respective pitch angle offset for the rotor blades of the wind turbine based on the estimated components of the rotor imbalance. The method also includes adjusting a pitch angle of each of the rotor blades by the respective pitch angle offset, thereby reducing first excitation magnitude disturbances on the acceleration of the tower.
