The utility model discloses an SVC simulation simulator based on a realtime digital simulation platform, comprising a reactor module, a shunt capacitor set module and a plurality of shunt reactance set modules, which are connected with the phase line of the realtime digital simulation platform and controlled by a thyristor. The SVC simulation simulator can be used for analyzing the fault problem of an electric power system equipped with SVC equipment, thereby reducing the possibility of fault generation of the electric power system equipped with the SVC equipment; and when the electric power system breaks down, the cause of the fault can be rapidly found out by using the SVC simulation simulator.
