摘　　要：针对传统电磁暂态仿真规模不够和机电暂态仿真精度不足,难以满足含高压直流输电(HVDC)和灵活交流输电(FACTS)设备的现代电网的仿真需要,总结和归纳了基于两者的混合仿真如何解决仿真规模、速度和精度的问题。比较了3种仿真技术,着重阐述了混合仿真的关键问题(包括网络的划分、接口的选择、网络的等值、数据通信的时序以及不同类型模型的统一连接等)。通过分析混合仿真的发展趋势,指出了实时混合仿真和超实时混合仿真的应用前景。Since the scale of electromagnetic transient simulation and the accuracy of electromechanical transient simulation can not meet the simulation requirement of modern power system containing HVDC and FACTS equipments, the issue of how to solve the problem of size, speed and accuracy in simulation by using hybrid simulation is studied. Three kinds of simulation technologies are compared and the key issues of hybrid simulation （including the division of network, the choice of interface, the equivalence of network, the order of data communication and the unification of different types of model and so on） are focused on. By analyzing development trends of hybrid simulation, it is suggested that the hybrid simulation in real-time mode and accelerated time mode has a big application prospect.
