Abstract

The invention relates to an electromagnetic transient and electromechanical transient hybrid simulation method based on a real time digital simulator (RTDS), belonging to the technical field of power system transient simulation. The method comprises the following steps: an electromechanical transient simulation system carries out electromechanical transient real-time simulation computation on a first power system; the RTDS carries out electromagnetic transient real-time simulation computation on a second power system; the electromechanical transient simulation system transfers the voltage and amperage of the first power system to the RTDS via an interface process control system and the RTDS carries out electromagnetic transient computation on the second power system by utilizing the voltage and amperage; and the RTDS transfers the voltage and electric power, which are obtained through simulation computation, of the second power system to the electromechanical transient simulation system via the interface process control system and the electromechanical transient simulation system carries out electromechanical transient computation on the first power system by utilizing the voltage and electric power.
