The invention provides a reactive compensation configuration method based on a reactive voltage feature for a wind power 500kV collecting transformer substation. The method comprises the following steps: determining the access capacity and access position of wind power accessing a power grid; determining inductive reactive compensation capacity and capacitive reactive compensation capacity needed by the power grid; determining the type and the capacity of reactive compensation equipment; determining a coordination control strategy of the reactive compensation equipment; detecting the stability of a wind power grid-connected system. By adopting the method, a reactive compensation configuration scheme is determined for the 500kV collecting transformer substation, so that a technical line is provide for the reactive compensation configuration scheme of the 500kV collecting transformer substation after the wind power accesses the power grid, and stable running after wind power grid connection is ensured.
