长大坡道区间牵引网上下行并联供电探讨

Discussion of Parallel Traction Power Supply Line on the Long Rampway Section

针对城市轨道交通的长大坡道区间,利用列车势能与动能的转换,从节能和改善牵引网电压降指标的角度,提出在该牵引供电分区内的合适位置将上下行线路牵引网并联供电的具体实施方案,同时提出实现配套多边联跳保护的设置方案,并对其安全性及节能效果进行分析。结果表明:利用列车势能与动能的转换,对于工程长期运营的综合节能效果较为显著,具有巨大的经济及社会效益。

For a long rampway section of urban raft transit, a detailed scheme of parallel traction power supply line is put forward at the suitable position by using the conversion between potential energy and kinetic energy, from the perspectives of saving energy and improving traction network voltage drop index, and the setting program to realize supporting multilateral inter-tripping protection is also presented. The safety and energy saving effect of the scheme are analyzed, and it is shown that the comprehensive energy saving effect of long-term operation is remarkable with huge economic and social benefits by conversion of potential energy and kinetic energy of train.
