The invention discloses a flexible torque control method for a wind turbine generator participating in frequency modulation near a rated wind speed, and belongs to the technical field of wind turbine generators. The method is used for solving the problem that torque switching control is abnormal when wind turbine generators above and below the rated wind speed participate in frequency modulation. Comprising the following steps: S1, setting an interval from a rotating speed omegagc (rad/s) to a rated rotating speed omegagN (rad/s) of a generator, and implementing control in the interval; s2, if the wind speed is smaller than the rated wind speed, the torque is controlled to be Tg1 (omegag, deltaf); if the wind speed is larger than the rated wind speed, the torque is controlled to be Tg2 (omegag, deltaf); and S3, solving the reference value of the torque of the generator of the wind turbine generator according to the Tg1 (omegag, deltaf) and the Tg2 (omegag, deltaf). The problem of abnormal ...
