摘　　要：越区供电是在牵引变电所故障时保障行车不中断的一种铁路应急处置方式,目前越区供电下的调度问题的研究尚不多见。越区供电下的行车组织调整方案有增大发车间隔和设置限速2种方式,为了研究对列车运行影响最小的2种方案组合方式,以通过能力损失最小为目标,建立越区供电下的列车运行调整模型,以某路网为背景,用CPLEX软件进行实例验证,计算出不同行车组织调整方案下的通过能力和晚点时间,最佳调度方案为限速250 km/h,发车间隔4~8 min。研究结果表明:限速对列车的影响大于增大发车间隔对列车的影响。Over-zone feeding is an emergency disposal in railway to make sure the trains run continuously when the traction substation breaks down.At present,study on rescheduling in over-zone feeding condition is rare.Train operation adjustment schemes include increase of headway and setting speed restrictions.To study the combination of two schemes which have the minimum impact on train operation,with the target of minimizing the carrying capacity loss,this paper established a train rescheduling model for over-zone feeding.Taking a rail network as the background,the benefits of the proposed model were demonstrated by numerical experiments based on CPLEX software.The carrying capacity and delay time for different train operation adjustment schemes were calculated.The best rescheduling scheme is the speed limit is 250 km/h and headway is 4~8 min.The results show that the impact of limiting speed on trains is greater than that of increasing headway.
