摘　　要：针对电气化铁路电分相引起的负序和列车供电不连续等问题,提出一种基于变电所同相供电和分区所地面自动过分相的虚拟贯通式同相供电系统,同时提出核心单元功能需求和相应的控制原理。该系统既可解决负序等电能质量问题,又可在接触网分段条件下实现列车通过中性区时连续供电,提升牵引网供电能力和供电品质。仿真结果验证了该虚拟贯通式同相供电系统的有效性。In response to the problems of negative sequence and discontinuous train power supply caused by electrified railway phase separation,a virtual through phase power supply system based on substation phase power supply and automatic ground passing through phase separation in section post is proposed.At the same time,the core unit functional requirements and corresponding control principles are proposed.This system can not only solve the problem of negative sequence and other power quality issues,but also achieve continuous power supply when the train passes through the neutral zone under the condition of segmented contact network,improving the power supply capacity and quality of the traction network.The simulation results have verified the effectiveness of the virtual through type in-phase power supply system.
