Zusammenfassung: | This paper presents a new interface approach in electromechanical transient and electromagnetic transient real time hybrid simulation in power system. The approach includes a parallel interface time sequence adaptable for real time hybrid simulation and an interface circuit adaptable for the parallel interface sequence. It also presents a new method to solve matrix asymmetry problem in electromagnetic transient simulation part caused by the connection of electromechanical network in hybrid simulation. Two cases are studied, modified IEEE 14 nodes system, and Dongbei-Huabei-Huazhong-Chuanyu interconnection system, an actual China power grid. The simulation results show that the hybrid simulation interface approach presented in the paper is valid and effective, and real time hybrid simulation for a 5000 nodes level electromechanical transient network and an electromagnetic transient network including 5 generators and more than 20 transmission lines is realized |
