摘　　要：简要介绍了电力系统仿真软件(PSS/E)动态仿真的基本原理。PSS/E 中的直流模型可以分为两类:一类考虑直流线路电感暂态过程和高频控制器动态特性,另一类不考虑以上动态特性。文章分析了这些直流模型的有效性和适用性,并通过准稳态直流动态模型 CDC4 进行了仿真研究,仿真结果表明 PSS/E 直流模型能够满足大规模交/直流系统仿真的要求。The basic principle of dynamic simulation by power system simulation software PSS/E is presented in brief. The HVDC models in PSS/E can be divided into two kinds, in one kind the inductive transient processes in DC transmission line and the dynamic characteristics of the high frequency DC controller are considered, and in the other kind the above mentioned processes and characteristics are not considered. The effectiveness and adaptability of these DC models are analyzed. Finally, the pseudo steady-state HVDC dynamic model CDC4 is studied in detail and is used to simulate the testing system. The simulation results show that the DC model of PSS/E can meet the need of the simulation of large scale AC/DC power systems, so it is available to apply PSS/E to the transient stability analysis of practical large scale AD/DC power system.
