The invention provides a wind power plant current collection control method and system. The control method comprises the following steps: establishing a wind turbine cluster based on wind speed and wind direction distribution; obtaining a wind power plant equivalent model represented by a plurality of wind power units; wherein the wind power plant equivalent modeling needs to follow the following principles: the grid-connected point voltage of a wind power plant aggregation model is equal to the grid-connected point voltage of a detailed model; the installed capacity of the generator set in the wind power plant aggregation model is the sum of the installed capacities of the wind generating sets in the detailed model, and the output active power and reactive power of the wind power plant aggregation model are equal to the output active power and reactive power of the detailed model. By adopting the control method, the calculated amount of short-term power prediction of the wind power plant station can be reduc
