Abstract

Systems and methods to reduce tower oscillations in a wind turbine are presented. The method includes obtaining a rotor velocity. Furthermore, the method includes obtaining one or more parameters associated with a tower of the wind turbine. Further, the method includes determining a modified rotor velocity based on the one or more parameters. Moreover, the method includes determining a first pitch angle based on the modified rotor velocity. In addition, the method includes pitching one or more blades of the wind turbine based on the first pitch angle to reduce the tower oscillations.
