摘要
小干扰分析法是分析电力系统稳定性的重要方法之一。为了分析研究电力系统次同步振荡以及次同步谐振现象,有必要开发一套可视化的电力系统SSO/SSR小干扰分析软件,应用于电网规划设计与仿真研究。软件开发过程中,小干扰建模是最重要、最核心的部分。将面向对象技术和模块化思想运用到适用于SSO/SSR分析的小干扰稳定性建模中,同时还提出了一种基于电磁暂态模型的电力网络通用建模方法,使得开发可视化通用型SSO/SSR小干扰分析软件得以实现。
Small signal analysis method is one of the most important methods in power system stability analysis. It is necessary to develop a visualized SSO / SSR small signal analysis program which can analyze subsynchronous oscillation( SSO) and subsynchronous resonance( SSR) phenomenon in power system. In the process of software development,small signal modeling is the most important task. In this paper,object-oriented technology and modularization are used in small signal modeling which can analyze SSO / SSR in power system. A general method for electric network modeling based on electromagnetic transient model is also put forward,which makes it realizable to develop general and visualized SSO / SSR small signal analysis software.
