A wind power generator set and a power control method and device therefor. The power control method comprises: when a power limit operation instruction or a power release operation instruction is received, controlling the rotation speed and torque of a generator of a wind power generator set on the basis of an optimal rotation speed and torque curve and a specific rotation speed and torque curve (S10), wherein for each point on the optimal rotation speed and torque curve, points, which meet a pre-set condition, on an equal power curve which takes the point as a starting point constitute the specific rotation speed and torque curve, and the pre-set condition is that the corresponding power value is a pre-set value lower than a power value corresponding to the point on the optimal rotation speed and torque curve under the same rotation speed value.
