摘要

单相自动重合闸是保证电力系统安全稳定的重要举措

在国内外超高压/特高压电力系统中得到了广泛的应用。笔者分析了相电流突变量选相原理及在高压输电线路单相自动重合闸中的应用。用MATLAB7.0仿真了相电流差突变量选相和相电流突变量选相方法

并结合继电保护模块和单相重合闸模块进行仿真分析。结果表明

应用MATLAB对单相自动重合闸故障选相进行仿真分析可获得很好的效果

对理解单相自动重合闸的原理很有帮助。

Abstract

This paper analyzed the phase selection principle based on mutation amount of phase-current

and discussed the application of the phase selection method to the single-phase automatic reclosing of high-voltage transmission line.MATLAB7.0 was employed to simulate both phase selection methods according to respective mutation amount of phase-current differential and mutation amount of phase-current

and the simulation results were analyzed referring to the relay protection module and the single-phase automatic reclosing module.The simulation via MATLAB exhibits the effectiveness in fault-phase selection of single-phase automatic reclosing.
