摘要
随着伊朗国内经济状况的好转,交通事业发展平稳有序进行,城市对轨道交通的安全稳定运行需求日益迫切,稳定的供电系统为地铁列车和各种辅助设备提供电力,是提高人们出行质量以及保证人们出行安全的前提。但是从近些年一些案例来看,地铁牵引供电系统直流侧易出现短路故障,这给城市轨道交通的安全运营带来了一定的影响。文章结合德黑兰地铁频发的直流侧短路故障案例,对直流侧短路电流对城市轨道交通供电的影响进行研究,为德黑兰地铁供电系统优化做出贡献。
With the improvement of Iran’ s domestic economic situation and the smooth and orderly development of transportation, the demand for the safe and stable operation of rail transit in cities is increasingly urgent. A stable power supply system to provide power for subway trains and various auxiliary equipment is the premise to improve people’ s travel quality and ensure people’ s travel safety. However, from some cases in recent years, the DC side of metro traction power supply system is prone to short-circuit fault, which has a certain impact on the safe operation of urban rail transit. Combined with the frequent DC side short-circuit fault cases of Tehran metro, this paper studies the influence of DC side short-circuit current on urban rail transit power supply, so as to contribute to the optimization of Tehran metro power supply system.
