摘　　要：在轨道交通传统差动保护和过流保护的基础上,提出了“近区速动保护”的保护理念和方案,通过差动保护和过流保护的信息实时交互,实现精确定位故障点、快速切除故障、快速恢复供电的近区速动保护方案。以上海轨道交通17号线供电系统的实际应用为例,分析并验证了近区速动保护方案在轨道交通供电系统中的优势.Based on traditional differential protection and overcurrent protection in rail transit,the concept and scheme of near boundary protection accelerated are proposed,which is to achieve the precisely locating the fault point,quickly removing the fault,and quickly restoring the power supply through the real-time interaction of the information of the differential protection and the overcurrent protection.Taking the power supply system of Shanghai Railway Line 17 as an example,the advantages of the near boundary protection accelerated in the power supply system of railways are analyzed and verified.
