| 摘 要： | 根据城市轨道交通1号线直流牵引供电系统部分供电区段内频繁出现的I_(max)保护动作问题,以牵引站用电量为分析依据,对变电站之间的牵引供电输出能力的匹配性数据进行了测试和分析,针对站间供电输出能力的不平衡问题进行调整,并对调整后的部分数据进行了测试和对比;有效地解决了直流牵引供电系统存在的部分车站输出能力不足的问题,提高了线路供电系统的安全性和可靠性。

| Abstract: | According to the frequent Imax protection trips in special supply section of the DC power supply system on Shanghai Metro Line 1 ,the matching data of traction pow-er output ability between DC traction substations are tested based on an analysis of the power consumption at traction substation. Following the conclusion,a partial data are tested and compared after the adjustment of the imbalance in the output capacity of power supply station.This method has effectively solved the problems of insufficient power supply between DC traction substations,improved the secu-rity and reliability of power supply system. |
