Abstract

It is described a method of individual pitch control of three rotor blades (4a,b,c) of a wind turbine (1), in particular for reducing loads, the method comprising: determining tilt moment (12) and yaw moment (15) acting on the wind turbine (1), in particular from load measurement signals (17a,b,c); determining at least one maximal amplitude (39,23,24) of a pitch angle offset based on the tilt moment (12) and the yaw moment (15), the maximal amplitude (39,23,24) of a pitch angle offset being in particular prioritized for the reduction of loading in a selected moment direction; deriving individual amplitudes (26a,b,c) of pitch angle offsets for the three blades (4a,b,c), the amplitudes being restricted to be not greater than the maximal amplitude (39,23,24) of a pitch angle offset.
