摘要

本文提出了一种基于MATLAB/Simulink的直流轨道故障电流精确建模方法。在引入短路电流集肤效应的基础上，提出了基于MATLAB/Simulink的短路故障仿真。通过对有集肤效应和无集肤效应的远端短路电流波形的比较研究，指出了这两种电流的区别。通过时间常数的计算，验证了该结果的有效性。

Accurate track modeling for fault current on DC railways based on MATLAB/Simulink

This paper presents an accurate track modeling for fault current on dc railways based on MATLAB/Simulink. With the introduction of skin effect of short-circuit current, the simulation of short-circuit fault based on MATLAB/Simulink is proposed. By comparing and investigating the waveforms of remote short-circuit current with and without skin effect, the paper pointed out the difference between these two currents. Moreover, the calculation of time constant proves the effectiveness of this result.
