The invention provides a limited power control method and system for a wind generating set, and the method comprises the steps: predicting a limited power control parameter of the wind generating set according to a power prediction parameter and the maximum output power of the wind generating set; when the maximum output power of the wind generating set is larger than the power set value of the wind generating set and the wind speed is larger than the first predicted wind speed threshold value, the rotating speed of the wind generating set is increased according to the first rotating speed threshold value; the pitch angle of the wind generating set is increased according to the first pitch angle threshold value, and the output power of the wind generating set is controlled; and when the maximum output power of the wind generating set is larger than the power set value of the wind generating set and the wind speed is larger than the second predicted wind speed threshold value, the pitch angle of the wind gener
