摘　　要：合宁铁路在全路首次采用四电系统集成模式,在系统集成技术创新方面取得了重大突破。本工程牵引供电系统采用了AT供电方式、全补偿弹性链形悬挂、220 kV AT供电方式三相Vv接线牵引变压器等关键技术,具有先进、优化、创新的设计理念。文章结合项目的供电方案、设备选用方案、继电保护方案、所址方案等具体情况,对牵引变电所、分区所、AT所的主接线方案进行了比选,分析了各方案的优缺点,确定了适合本项目特点的主接线方案。对项目设计思路及特点进行了总结,为今后时速300 km以下AT供电方式牵引变电系统设计提供了技术支持,其主要设计方案在东南沿海铁路、成绵乐城际、南广铁路、广西沿海铁路、长昆客运专线、贵广客运专线、西成客运专线、成渝客运专线、云桂铁路等长大干线中得到了广泛应用。Four-Electric Integration （railway communication, signaling, power supply and traction power supply engineering） is applied for the first time for Hening Railway in China, and achieved great breakthrough in the innovation of system integration technique. A series of key technologies including AT power supply mode, all tensioned elastic catenary suspension, 220 kV AT three phase traction transformer with Vv connection are used for traction power supply system of the project, which are characterized by advanced, optimized and innovated design concept. With combination with the power supply scheme, equipment selection scheme, relay protection scheme and substation location scheme, in this paper, a comparison is made on all main wiring schemes of traction substations, section post and AT stations and a detailed analysis is made on the advantages and disadvantages of each scheme. According to comparison and analysis resuits of the schemes, a main wiring scheme suitable for the characteristics of the project is determined. Design thought and characteristics of the project are summarized in this paper, which may provide technical support for design of traction substation system with AT power supply mode less than 300 km/h in the future. The main design scheme has been widely used for such long trunk railways as southeast coastal railway, Chengdu-Mianyang-Leshan intercity railway, Nanning- Guangzhou railway, Guangxi coastal railway, Changsha-Kunming passenger dedicated railway, Guiyang-Guangzh senger dedicated railway, Xi＇an-Chengdu passenger dedicated railway, Chengdu-Chongqing passenger dedicated and Yunnan-Guangxi railway.
