电磁暂态仿真系统EMTS及其在高压直流系统仿真分析中的应用

电磁暂态仿真系统(electro-magnetic transient simulator，EMTS)是中国电力科学研究院自主开发的大型电力系统全数字仿真系统的一个子系统。它具有先进性、开放性、可扩展性以及友好的人机界面，并具有与机电暂态程序的接口，以实现在同一次仿真过程中与机电暂态程序一起对大规模电网进行混合仿真。首先介绍了该系统的设计思想、体系结构、设备配置及软件组成，并应用该仿真系统对三峡—广东直流输电系统进行了一系列仿真研究，仿真结果与实际工程和理论分析的特性相近，能够满足直流仿真要求。

Electro-Magnetic Transient Simulator and its Application in HVDC Simulation

Electro-Magnetic Transient Simulator (EMTS), which is independently developed by China Electric Power Research Institute (CEPRI), is a computer cluster based fully digital simulation system for power grid. It is an advanced, open and expendable system with high calculation speed and friendly man-machine interface. During the same simulation, EMTS can be integrated with electromechanical transient program to conduct hybrid simulation of large-scale power grid. In this paper, at first the authors present the design thinking, architecture, hardware configuration and software constitution of EMTS; then its application in the simulation of HVDC transmission project from Three Gorges Hydropower Station to South China Power Grid is described in detail. Simulation results are similar to the characteristics from theoretical analysis and practical engineering, so it is proved that EMTS can meet the requirement of the research on HVDC.
