城市轨道交通车辆应急供电系统研究

Research on Emergency Power Supply System of Urban Rail Transit Vehicle

城市轨道交通车辆以车载蓄电池组或新增电池箱来保障应急供电,可有效应对供电系统的故障问题,并实现城市轨道交通车辆自身的主动救援。分析了国内城市轨道交通线路应急供电系统的应用现状。设计了4种不同应用场合的应急供电系统,并对其工作原理及特点进行了对比分析,同时研究了其在应急供电下的整车控制逻辑。结果表明:应急供电系统对提升车辆自我救援能力、探索新节能方式具有重要意义。

On-board battery or additional battery case is applied to ensure emergency power supply for urban rail transit vehicles,which can effectively deal with the power supply failure and realize the active rescue of vehicle itself.The application status of the emergency power supply system for domestic urban rail transit lines is analyzed.Four systems applicable to different scenarios are designed,and the working principle and characteristics are comparatively analyzed.Meanwhile,the vehicle control logic under emergency power supply is studied as well.Results show that emergency power supply has significant importance to elevating vehicle self-rescue ability and exploring new energy-saving methods.
