Abstract
The present invention provides a power control method, device and system for a wind power station. The power control method comprises: obtaining running state data of the wind power station and a grid connection point in real time; determining whether the state of the grid connection point meets conditions of secondary frequency modulation according to the running state data; if it is determined that the state of the grid connection point meets the conditions of secondary frequency modulation, determining a limited power instruction value according to a pre-obtained theoretical power value of the wind power station, a given value of automatic power generation control, and a standby active power value reserved for primary frequency modulation; and generating and sending an instruction used for controlling the active power of the wind generating set of the wind power station according to the limited power instruction value.
