Zusammenfassung:A wind turbine plant and a power control method and device thereof are provided. The power control method comprises: controlling rotational speed and torque of a generator of the wind turbine plant based on an optimal rotational speed torque curve and a specific rotational speed torque curve, when receiving a power-limiting operation instruction or a power-releasing operation instruction; wherein, for each point on the optimal rotational speed torque curve, the specific rotational speed torque curve includes a point on an isopower curve starting from said point that satisfies a predetermined condition, and wherein the predetermined condition is that a corresponding power value of said point on the isopower curve is lower than a power value corresponding to a point on the optimal rotational speed torque curve at the same rotational speed value as said point on the isopower curve by a predetermined value.
