摘　　要：铁路电力系统普遍采用三相10 kV 50 Hz供电制,承担着铁路电力自闭线、贯通线、站馈线等重要负荷供电重任,一二级负荷多,供电质量要求高。传统供电方式存在电能质量差、供电可靠性低、建设管理成本高、资源浪费等问题。本文提出了一种高可靠性补偿式铁路净化电源系统方案,利用交直交电力电子变换装置和串联耦合变压器对牵引供电网电源进行净化和补偿,解决牵引供电网电能质量和可靠性问题。Railway power system,with feeding electric power to railway power self closing line,through line,station feeder etc,generally uses three-phase 10 kV 50 Hz power supply system.There are many primary and secondary loads in the system with high demands on power supply quality.Aiming at the problems,such as poor power quality,low power supply reliability,high cost of construction and management,waste of resources and so on.,a scheme of the railway power supply system is proposed in this paper.AC-DC-AC power electronic conversion device and series coupling transformer are used to purify and compensate the power supply of traction power supply network and to solve the problems of power quality and low reliability of traction power supply network.
