Equivalent aggregation simulation method for electromagnetic transient simulation of large-scale wind farm

The invention belongs to the field of a power system, and particularly relates to an equivalent aggregation simulation method for electromagnetic transient simulation of a large-scale wind farm. The invention provides an aggregation simulation method for simulating the large-scale wind farm by a single wind turbine and an ideal controlled current source according to the basal principle of an electromagnetic transient simulation algorithm of a power system and the characteristics of dynamic equations of a motor and a control system as well as an algebraic equation solving algorithm of an electric network. By adopting the equivalent aggregation simulation method for carrying out related research on synchronization of the large-scale wind farm, the complexity of modeling the large-scale windfarm can be reduced, and the modeling efficiency can be improved.
