Fault Location Analysis of Direct Supply Traction Power Supply System with Reinforcement Line

在Matlab/Simulink仿真环境下,根据带加强线的直供牵引供电系统的特点建立仿真模型.分析了牵引系统故障时的故障特征,提出对现有故障定位方法的改进办法,用以解决带加强线的直供牵引供电系统传统故障定位方法中无法区分线别的问题,减少接触网停电时间,辅助接触网运维人员巡线.

In MATLAB/Simulink simulation environment,the simulation model is established according to the characteristics of the direct supply traction power supply system with reinforcing wire.The fault characteristics of traction system are simulated and analyzed,and some personal suggestions are proposed for the existing fault location methods to solve the problem that the traditional fault location method of direct supply traction power supply system with reinforcement line cannot distinguish lines,reduce the outage time of contact network and assist the operation and maintenance personnel of contact network to patrol the line.
