基于MATLAB的水力发电系统短路故障仿真分析

Short-circuit Simulation Analysis on Hydropower-generation System Based on MATLAB

本文详细介绍了在MATLAB软件Simulink/SimPowerSystems环境下,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,对水力发电系统三相短路故障进行仿真分析。其仿真结果表明,该方法不但符合理论计算结果,而且还可以对各种情况下的短路故障进行实时动态可视化研究。

This paper builds a model of single-machine-infinity-bus system within MATLAB Simulink / SimPower Systems environment, and analyses three-phase s/c malfunction in hydropower generation system through module selection, parameter setting and matching. The results shows that the method is not only consistent with theoretical calculations, but also applicable to real-time dynamic visualization study of s/c malfunctions in all cases.
