| 摘 要： | 在既有牵引供电系统事故恢复的基础上,提出了一种以开关作为节点．开关间线路作为支路的节点-支路关联矩阵描述牵引供电系统接触网拓扑结构,并给出了基于这种关联矩阵的故障区域判断与隔离的方法,能够实现对接触网故障进行准确定位．迅速隔离故障区段,减少了牵引供电系统的故障停电范围,提高了供电的可靠性。

| Abstract: | Based on existing traction supply system, "Node-branch incident matrix" is introduced to describe the topology of OCS feeder net,which regards switch as nodes and lines connecting the switch as branches.A new method based on the incident matrix is presented to identify and isolate faulty section,which is fast and accurate,the area of faulty section is hence reduced and the supply reliability enhanced. |
