基于 Matlab 的电力系统故障分析与仿真摘 要:本文介绍了 MATLAB 软件在电力系统中的应用,以及利用动态仿真工具 Simulink和电力系统工具箱 PSD 进行仿真的基本方法
在仿真平台上,以单机-无穷大系统为建模对象,通过选择模块,参数设置,以及连线,对电力系统的多种故障进行仿真分析
同时,设计一个 GUI 图形界面,将仿真波形清楚地显示在界面上以便比较和分析
结果表明,仿真波形基本符合理论分析,说明了 MATLAB 是电力系统仿真讨论的有力工具

On MATLAB simulation platform, take a single machine—infinite-bus system as modeling objects, by selecting the module, parameter settings, and connectingmodules to simulate and analysevariousfault of power system
At the same time, in order to facilitate comparison and analysis simulation waveform, design a GUI for showing waveform clearly
The results show that the simulation waveform in
