摘要
分析了1.5 kV直流牵引供电系统DDL馈线保护的整定计算方法,对某一实际运行的地铁区间建立了数学模型,通过仿真分析了不同地点列车启动电流和故障电流的特点,并完成了对DDL保护的配置,为直流牵引供电系统的保护设计提供参考。
On the basis of analyzing the calculation method for settings of DDL feeder protection for 1.5 kV DC traction power supply system, a mathematic model is established for a practical operating subway section, and configuration of DDL protection has been finished after simulation and analysis of characteristics of train starting current and fault current at different locations, these provide references for protection and design of DC traction power supply system.
