摘要： A method is provided for operation of a wind turbine 10 having rotor blades 22 attached to a hub 20, wherein a controller 26 compensates for torsionally induced blade twist. The method includes operating 200 the wind turbine according to a rated power output curve and maximum design thrust value, and periodically or continuously detecting 202 for induced torsional twist in the rotor blades 22. Upon determination of torsional twist being induced in the rotor blades 22, the method includes adjusting 210 the maximum thrust value in the control program to compensate for the induced twist. The wind turbine controller 26 then controls 212 pitch of the rotor blades 22 as a function of the increased maximum thrust value so that power output of the wind turbine 10 is not unnecessarily limited or increased by the induced twist on the rotor blades.
