摘　　要：针对目前电力系统稳定分析所采用的机电暂态仿真软件PSD-BPA无法准确反映直流系统的动态过程,电磁暂态软件PSCAD/EMTDC等无法对大电网详细建模的问题,采用中国电力科学研究院自主研发的电磁暂态软件PSModel(Power System Model)与PSD-BPA程序进行交直流系统混合仿真。本文对PSModel仿真程序的算法和混合仿真原理进行了介绍,对搭建的内蒙古电网异步联网工程模型进行混合仿真分析,验证了搭建的混合仿真模型的正确性。The electromechanical transient simulation software PSD-BPA used in the current power system stability analysis cannot accurately reflect the dynamic process of the DC system,and the electromagnetic transient software PSCAD/EMTDC cannot implement detailed modeling of the large power system.The electromagnetic transient software PSModel(Power System Model)independently developed by China Electric Power Research Institute is used to carry out hybrid simulation of AC and DC systems with PSD-BPA programs.This paper introduces the algorithm and hybrid simulation principle of the PSModel simulation program.Finally,the hybrid simulation analysis of the asynchronous interconnection project of Inner Mongolia Power Grid is established,and the validity of the hybrid simulation model is verified.
