摘要
以大秦线2亿t扩能改造工程为例,通过对AT牵引供电系统在AT所并联、不并联2种情况下阻抗特性的比较和分析,提出了全并联AT牵引供电方式继电保护配置方案和保护整定原则。
Take example for the 200 million-tons reconstructing of the Datong-Qinhuangdao railway, through comparison and analysis on the impedance characteristics of the AT traction power supply system under two conditions that the upstream and downstream Overhead contact lines are paralleled and unparalleled at the AT substation, it bring forward the Relay protection configuration scheme and Relay protection setting principles for the Entirely parallel AT traction power supply system. =
