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.

Wind turbine plant and power control method and device thereof

Provided are a control method and apparatus for load reduction of a wind turbine. The control method for load reduction includes: determining a representative blade root load value of a wind turbine; determining an additional pitch rate value based on the representative blade root load value; determining a pitch rate control value based on a given pitch rate value and the additional pitch rate value; and applying the pitch rate control value to each blade of the wind turbine, to control each blade of the wind turbine to perform a pitch action.
