Abstract

A method (100) for reducing loads of a wind turbine (10) includes determining a wind speed at the wind turbine (10). Further, the method (100) includes determining an operational state of the wind turbine (10). The method (100) also includes determining whether a rotor (18) of the wind turbine (10) is imbalanced beyond a predetermined threshold when the operational state corresponds to a predetermined operational state (as a rotor imbalance beyond the predetermined threshold is indicative of a pitch fault in one or more of the rotor blades (22)). In addition, the method (100) includes yawing a nacelle (16) of the wind turbine (10) to a predetermined angular position when the wind speed exceeds a predetermined speed threshold and the rotor (18) is imbalanced beyond the predetermined threshold.
