Abstract

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