在MATLAB／SIMULINK仿真环境下，根据带加强线的全并联直接供电系统的结构特点建立仿真模型。仿真分析了牵引网短路故障时的阻抗特性，并比较了牵引网不带加强线和带加强线时短路阻抗的大小；同时还仿真分析了正常运行情况下牵引网的电流分配关系。
在MATLAB／SIMULINK倣真環境下，根據帶加彊線的全併聯直接供電繫統的結構特點建立倣真模型。倣真分析瞭牽引網短路故障時的阻抗特性，併比較瞭牽引網不帶加彊線和帶加彊線時短路阻抗的大小；同時還倣真分析瞭正常運行情況下牽引網的電流分配關繫。

This paper adopts simulation method, simulation models are build according to design feature of all parallel direct power supply with strengthen wire .In case of short circuit for traction electric network, impedance of traction electric network measured in traction substation is shown, and compared no strengthen wire with the strengthen wire of the size of the short-circuit impedance. When traction electric network is under the condition of normal operation, the distribution of traction electric network current is shown as well
