摘　　要：随着电网互联规模的扩大以及大量电力电子设备的接入,为更好地满足对电力电子设备接入后的复杂电力系统仿真分析的需求,采用机电暂态与电磁暂态结合的混合仿真能够很好地解决系统仿真规模、速度和精确性的问题。论述了机电-电磁暂态混合仿真技术的发展历史和现状,对现今国内外采用的混合实时仿真平台进行了归纳总结。在此基础上,就混合仿真接口技术的关键问题从等值形式、数据转换、接口位置选择和交互时序4个方面进行了详细讨论。论述了各个方面的内容、技术难点以及面临的主要问题。最后,提出了混合仿真技术未来可能的发展方向及相关问题。With the expansion of power grid interconnection and the access of a large number of power electronic devices, in order to fulfill the need of analysis requirements of complex power system simulation after power electronic equipment accessing, it＇s shown that adopting hybrid simulation of combining electromechanical transient simulator and electromagnetic transient simulator can solve the scale, velocity and calculation precision of system simulation. The developmental history and current situation of electromechanical-electromagnetic transient hybrid simulation are discussed and the existing domestic and foreign hybrid simulation platforms are comprehensively summarized. On this basis, the interfacing technology of hybrid simulation is discussed in four aspects： equivalent model, data conversion, interfacing location selection and interaction sequence. The connotation, technological difficulties and main problems of each aspect are introduced. Finally, this paper proposes the probable development direction and relevant problems of hybrid simulation technology in future.
