基于 MATLAB 的距离保护仿真摘要:本文阐述了如何利用 Matlab 中的 Simulink 及 SPS 工具箱建立线路的距离保护仿真模型,并用 S 函数编制相间距离保护和接地距离保护算法程序,构建相应的保护模块,实现了三段式距离保护
仿真结果表明,所建立的三段式距离保护模型能够正确反应在保护区内的不同类型的短路故障并发出动作信号使断路器跳闸实现输电线路的保护功能

We programed the distance protection of phase faults and earth faults by using S-Fuction and created relevant protection models to build distance protection
The simulation results show that the three-stage distance protection model we created can response to all kinds of faults within protection zones correctly and send correct signal to the breaker of the line
