城市轨道交通牵引供电系统的主接线设计

牵引变电所和降压变电所是城市轨道交通牵引供电系统的重要组成部分,其主接线应能满足安全、可靠、经济、接线简单、运行灵活的要求。文中根据城轨交通牵引供电系统主接线的工程设计原则及运营经验,结合国内外整流机组、开关设备的技术发展,从技术可靠性、运行灵活性及工程投资经济性等方面对国内常用的城市轨道交通牵引供电系统的中压交流侧和牵引直流侧主接线形式进行详细比较和分析,提出了城轨交通牵引供电系统主接线的建议方案。

Design of main wiring for urban rail transit traction power supply system

Traction substation and step-down substation are important parts of traction power supply system,whose main electrical wiring should be able to meet the requirements of safety,reliability,economy,simple wiring and flexible operation.Based on the engineering design principles and operating experience of urban rail transit traction power supply system’s main wiring,and combining the technology development of rectifier unit and switching equipment at home and abroad,this paper gave a detail comparative analysis on the main electrical wiring form of the traction power supply system of the urban rail transit on AC medium voltage side and DC traction side commonly used in China from the technical reliability,operational flexibility,and economy of project investment.Finally,it put forward a proposal for the main electrical wiring of urban rail transit traction power supply system.
