太原铁路枢纽高铁供电运行探讨

Discussion on Traction Power Supply Operation of High Speed Railway in Taiyuan Railway Hub

随着太原铁路枢纽融入高速铁路网,枢纽内高铁列车数量大量增加,但枢纽内高铁接触网仍由榆次变电所、太北变电所这两座既有普速铁路牵引变电所供电。为保证高铁的供电可靠性,结合太原铁路枢纽内线路及牵引供电设施布置,分析在牵引变电设备各种故障情况下如何快速恢复供电。在榆次或太北牵引变电所发生全所停电故障时,对几个可以实现的越区供电方案进行供电能力计算和比较,提出推荐的越区供电方案。通过良好的供电故障恢复方案,能极大地提高太原铁路枢纽内供电故障恢复速度和高铁列车供电的可靠性。

With the integration of Taiyuan railway hub into high-speed railway network,the number of high-speed trains in the hub is increasing rapidly,but the power supply of the overhead contact lines in the hub is still provided by the existing Yuci traction substation and Taiyuanbei traction substation,which are normal-speed railway traction substations. In order to improve the reliability of power supply for high-speed railway,this paper,with reference to the lines and traction power supply facilities in the hub,addresses how to restore the power supply quickly in case of various fault conditions of the traction substation equipment. In case of power failure of the entire Yuci traction substation or Taiyuanbei traction substation,calculation and comparison of the capacities of several over-zone power supply programs are conducted to determine the recommended program. With a good power recovery program,the speed of power recovery and the reliability of power supply of high-speed railway in Taiyuan railway terminal can be guaranteed.
