牵引供电系统相间短路分析及保护设置

Inter-phase Short Circuit Analysis and Protection Settings of Traction Power Supply System

对AT、直接供电方式牵引供电系统经常发生的各种相间短路现象进行了分析,对牵引变电所馈线综合自动化保护的设置及整定计算进行了探讨,提出了较为完善的相间短路保护设置及整定建议。

This paper analyses each kind of inter-phase short circuit phenomenon which often occurred in AT and direct feeding traction power supply system, discusses the settings and calculation of feeder integrated automatic protection in traction substation, and suggests comparative perfect advice of inter-phase short circuit protection settings.
