| 摘 要： | 对全并联AT供电牵引网断线接地故障时变电所出口处的测量阻抗进行了理论分析与推导;结合接触网实际参数,采用Matlab/Simulink进行了仿真,给出全并联AT供电牵引网各种短路、断线接地故障的测量阻抗—距离特性曲线;最后针对全并联AT供电方式供电臂以负荷开关进行并联的接线形式,给出供电臂保护配置方案,以期为全并联AT供电牵引网馈线保护的配置提供参考。

| Abstract: | In this paper, the complex grounding fault with interruption of all-parallel AT traction power supply system is analyzed. And the impedance-distance curves of this fault and the routine fault are presented. Through contrast with the routine faults, the conclusions are acquired. And the Relay protection configuration scheme for all-parallel AT traction power supply system is provided. |
