地铁重联列车区间故障救援仿真分析

Simulation Analysis of Interval Fault Rescue of Metro Reconnection Train

针对地铁固定编组列车在客流高峰时期运能不足,客流低峰时期运能浪费等问题,可通过开行重联编组列车较为有效地解决地铁客流与运能的匹配问题。但是,地铁重联编组列车故障的频发对区间列车运营造成很大影响,需尽快制定地铁重联列车区间故障的救援方案。通过分析重联编组列车的故障救援过程及影响要素,以重联大编组列车、小编组列车为例,对地铁线路区间的重联列车进行4种不同场景的故障救援仿真分析,结果表明,除小编组列车救援大编组重联列车场景中需根据线路情况对故障救援方案进行调整,其余救援场景均可实现后续列车故障救援,研究结果对地铁重联编组列车故障救援方案的实施具有一定的参考价值。

Metro trains under fixed marshalling are insufficient in transportation capacity during the peak period of passenger flow and waste transportation capacity during the off-peak period. Reconnection marshalling can effectively address the mismatching between metro passenger flow and transportation capacity. However, the frequent faults of reconnection marshalling trains have a great impact on the operation of section trains. Thus, there is an urgent need to formulate a rescue scheme for the interval faults of metro reconnection trains. After analyzing the fault rescue process of reconnection trains and its influencing factors, this paper took large reconnection marshalling trains and small marshalling trains as examples to simulate and analyze the fault rescue of reconnection trains in metro line sections under four scenarios. Except that the fault rescue scheme needs to be adjusted according to the line situation in the scenario of a small marshalling train rescuing a large reconnection marshalling train, other rescue scenarios can realize the fault rescue by the subsequent trains. The research results have a reference value for the implementation of fault rescue schemes of metro reconnection marshalling trains.
