First information is provided which is representative for a bending moment of the rotor blade. Second information is provided which is representative for the wind turbulence intensity at the rotor. Third information is provided which is representative for a predetermined maximum allowed bending moment of the rotor blade. The maximum allowed bending moment depends on the wind turbulence intensity at the rotor. Fourth information is determined depending on the first, second and third information and is representative for whether the bending moment exceeds the maximum allowed bending moment. If so, an output signal is generated and configured to cause the pitch setting system to change the pitch angle of the rotor blade to reduce deflection of the rotor blade towards the tower when passing the tower.

A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. An allowable yaw sweep is defined for the limited yaw capacity state. A sensor in communication with a controller monitors for vibrations in the blade with the rotor at an initial yaw position. Upon detection of vibrations, the controller determines a yaw sweep sector that is within and less than the allowable yaw sweep and issues a command to a yaw system to yaw the rotor in a continuous back and forth manner in the yaw sweep sector. The controller continues to monitor for vibrations in the blade during or after the continuous yawing of the rotor and stops the continuous yawing of the rotor when the blade vibrations reduce to below the threshold level.
