基于PSASP的电力系统稳定性仿真分析

Power System Stability Simulation Based on PSASP

简要介绍了电力系统暂态稳定性的基本概念以及电力系统综合程序(PSASP)的基本内容,详细叙述了静态负荷模型和动态负荷模型。然后以一个三机系统为例,应用电力系统分析综合程序(PSASP)进行仿真,分析不同的负荷模型对电力系统暂态稳定性影响,得出采用静态负荷模型应考虑频率特性的影响,采用综合负荷模型应选择合适的感应电动机和恒阻抗的比例。

This paper briefly gives a description of the concept of power system stability and the content of Power System Analysis Software Package（PSASP）, and illustrated static and dynamic load model in detail. Taking an three machines system as example, through the simulation of it by PSASP , the influence of different load models on power system transient stability is analyzed. The result shows in static load model the influence of frequency characteristics should be considered,and the appropriate proportion of inductive motor and constant impedance was selected for integrate load model.
