徐盐铁路引入徐州东枢纽牵引供电方案研究

徐盐铁路位于苏北地区,连接京沪、陇海、连镇、沿海四大铁路通道,是长三角城际网重要组成部分,也是京沪通道徐州-上海段的辅助通道,其引入徐州东枢纽以实现京沪高铁、郑徐高铁以及连徐高铁等4条线路的换乘,而枢纽地区牵引供电方案的合理性至关重要。因此,本文对徐盐铁路引入徐州东枢纽供电方案进行论证比较,并根据电分相检算分析提出推荐方案,以保证京沪高铁运行可靠性及工程实施的便捷性。

Study on Traction Power Supply Scheme of Xuzhou-Yancheng High-Speed Railway Leading into Xuzhou East Hub

Xuzhou-Yancheng High-Speed Railway is located in northern Jiangsu,connecting Beijing-Shanghai Railway,Lanzhou-Lianyungang Railway,Lianyungang-Zhenjiang High-Speed Railway and coastal railway,is an important part of the intercity railway network of the Yangtze River Delta,and also an auxiliary channel;of the Xuzhou-Shanghai section of Beijing-Shanghai Channel.The project introduces Xuzhou East Hub,which is responsible for realizing the transfer of four lines including Beijing-shanghai High-Speed Railway,Zhengzhou-Xuzhou High-Speed railway and Lianyungang-Xuzhou High-Speed Railway.The rationality of the traction power supply scheme in the hub area is particularly important.Therefore,this paper demonstrates and compares the power supply schemes of Xuzhou-Yancheng High-Speed Railway leading into Xuzhou East Junction,and proposes the recommended scheme according to electricity phase check calculation analysis,so as to ensure the operation reliability of Beijing-Shanghai High-Speed Railway and the convenience of project implementation.
