摘要:

为实现换乘的便利性,以及为节省用地而共用交通走廊，城市越来越多的地段出现了交流制式的电气化铁路和直流制式的城市轨道交通线路近距离并行敷设的情况。当交流电气化铁路正常稳态运行或发生故障时，流过交流电气化铁路的交流电流通过交、直流线路间的电容和互感，会在直流轨道交通牵引网供电系统上感应出工频电压, 从而导致直流轨道交通牵引网上出现工频电流。阐述了感应电压的危害，并提出了降低感应电压的防范措施。通过计算分析及试验测试，说明采用的防范措施能够较好地减少感应电压，对交、直流系统并行区段的供电系统设计具有指导意义。

In order to facilitate passenger transfer and save land by using the traffic corridor, the parallel laying phenomenon of AC\|based electrified railway and DC\|based urban rail transit lines are increasing in urban areas. When the AC electrified railway is in normal steady state operation or in failure condition, the AC current flowing through AC electrified railway will pass through the capacitance and mutual inductance between the AC and DC lines, and induce the power frequency voltage on the traction network system of DC rail transit, resulting in the power frequency current on the traction network of DC rail transit. In this paper, the harm of induction voltage is expounded, preventive measures of reducing induction voltage are studied. Through calculation analysis and experimental test, it proves that the preventive measures can effectively reduce the induction voltage, therefore has a guiding significance for the design of power supply system in the parallel section of AC/DC systems.
