In this paper, the hybrid simulation platform＇s system scheme is stated together with the key technologies including real-time electromechanical transient simulation technology of large-scale power grid technology, interactive technology of sequences variables between electromagnetic and electromechanical transient, the high speed digital communication technologies among RTDS and computer. Applications of the SMRT platform to the analysis of CSG＇s operation characteristics and to the operator training are illustrated.
