The invention discloses a parameter equating method for a aggregation model of a doubly-fed generator set wind power station. The parameter equating method mainly includes: subjecting the doubly-fed generator set in a wind power station to generator model parameter equating, shaft system parameter equating, transformer parameter equating and wind speed equating; subjecting an inner current collection circuit of the wind power station to equivalence processing according to a connection mode, and integrating the aggregation equating parameters of above links to obtain the aggregation model of the doubly-fed generator set wind power station. By the parameter equating method, defections like poor stability, low reliability and small application range in an existing aggregation modeling technology of the wind power station can be overcome, and the parameter equating method has the advantages of good stability, high stability and wide application range.
