System and method for reducing wind turbine rotor blade loads

Abstract:

The present disclosure is directed to a method for reducing loads of one or more rotor blades of a wind turbine. The method includes monitoring a load of a first rotor blade. If the load of the first rotor blade exceeds a first load threshold, the method also includes designating a rotor plane sector in which the first rotor blade is located as a high load rotor plane sector. The method further includes adjusting, via a pitch drive mechanism, a pitch angle of a second rotor blade toward a first position before the second rotor blade enters the high load rotor plane sector.
