The invention relates to an active power distribution coordination method of units in a wind power plant and belongs to the technical field of electric power system automatic analyzing. The method is characterized in that fan critical rotation speed is obtained through wind turbine generating unit balance point stability analyzing, the units in the wind power plant are divided into non-controlled units and controlled units according to the critical rotation speed, the non-controlled units and the controlled units are allowed to use different active output manners according to the different output features of the two kinds of units, and unbalanced energy is proportionally distributed among the controlled units according to the actual stored energy of the units. The method has the advantages that the method is easy to implement and small in calculation amount, an operator can reasonably distributes the active output of the units in the wind power plant by the aid of the method, safe and economic system operation under the background that new energy is accessed to a power grid is powerfully guaranteed, sustainable, stable and healthy development of the power grid is promoted, national energy safety guarantee capability is increased favorably, and evident social and economic values are achieved.
