摘　　要：自愈功能作为保证直流牵引供电系统安全可靠运行的关键功能,具有重要的研究意义。在故障自愈目的的基础上,介绍了直流母线故障的自愈方案原理,该方案基于保护优先的原则,包括故障跳闸、故障判断定位、故障恢复3个组成部分。然后基于工程应用角度,提出了直流母线故障越区供电自愈方案,并论述了越区供电自愈方案的系统结构及其工作流程。Self-healing is the key function to ensure safe and reliable operation of DC traction power supply system.Based on the purpose of fault self-healing,this paper describes the principle of self-healing for DC bus faults,which taking the largest priority in protection consists of fault trip,fault judgment and positioning,and fault recovery.Then from the perspective of engineering application the paper proposes a cross-area supply-based self-healing scheme for DC bus faults area,and discusses system structure and workflow of the scheme.
