Abstract (en)
[origin: WO2021233706A1] The invention relates to a method (200) for controlling a wind power plant (100) having a rotor with at least one rotor blade (17), the method comprising: measuring (210) a strain of the at least one rotor blade; changing (220) a pitch angle of the at least one rotor blade at least partially on the basis of the measured strain of the at least one rotor blade; the measuring of the strain of the at least one rotor blade measuring at least a strain in the region of the root of the rotor blade (17).
