Abstract
The invention provides a power control method and a power control system for a wind generating set. The method comprises: acquiring an actual torque TN and a preset torque TM of the wind generating set; and judging whether a first PID controller and a second PID controller of the wind generating set need to be simultaneously operated according to the actual torque TN and the preset torque TM, and if so, simultaneously operating the first PID controller and the second PID controller. According to the power control method and the power control system for the wind generating set, by judging whether the first PID controller and the second PID controller of the wind generating set need to be simultaneously operated in real time, flicker of the wind generating set can be reduced, and the wind generating set can work in a state as close to an optimal state as possible.
