摘要

介绍了一种新型的电压稳定工具箱(VST)，该工具箱是用Matlab数学语言编写的，并详细介绍了其开源代码的特点和一套完整的友好图形界面。采用标准牛顿-拉夫森(NR)和牛顿-拉夫森-塞德尔(NRS)收敛算法对电力系统的电压稳定性和分岔进行分析。VST的主要功能包括潮流分析、时域仿真、奇点分析、本征分析以及静态和动态分岔分析。VST是理解电压稳定性和非线性分岔现象的一个非常有用的工具。最后给出了该工具箱在三台发电机五母线系统和30母线测试系统中的应用测试结果，验证了该工具箱的实用性和有效性。

Matlab-based voltage stability analysis toolbox and its validity check

A novel Voltage Stability Toolbox(VST) is introduced, which is programmed using Matlab math language, and the features of its open source code and a complete set of user-friendly graphical interfaces are detailed. It implements standard Newton-Raphson (NR) and Newton-Raphson-Seydel (NRS) convergent algorithms to analyze the voltage stability and bifurcation of power system. The main functions of VST include power flow, time domain simulation, singularity analysis, eigen-analysis, as well as static and dynamic bifurcation analysis. VST is a very helpful tool to understand voltage stability and nonlinear bifurcation phenomenon. Test results of the application of this toolbox in a five-bus system with three generators and 30-bus test system are presented to show the practicality and effectiveness of the VST.
