铁路客运专线列车运行调整策略仿真分析

Simulation Analysis of Train Rescheduling Strategies in Railway Operation of Passenger Dedicated Line

针对客运专线高中速列车共线运行的组织模式,首先综合考虑列车等级、正晚点状态及剩余运程等因素,分析了调度员可采取的运行调整策略,在此基础上模拟调度员在不同的晚点设置条件下,利用不同调整策略进行运行调整的过程,并重点对各类晚点列车数量及时间等指标进行了分析。通过仿真分析可以发现:1)高速列车的抗干扰能力比较强,当列车晚点时,令所有列车按现有次序运行可获得较好的效果;2)当中速列车不允许影响高速列车时,其抗干扰能力较差,应适当安排远程车及正点车先行;反之,其抗干扰性大为提高,并且当高速列车可被连带移动的时间不大于实际列车间隔时间时,对高速列车的影响较小。

It took various factors including train class, delay status and remained distance into account to analyze the possible rescheduling strategies in train operation of passenger dedicated line under the operation mode with both high-speed and middle-speed trains. On this basis, the process of train rescheduling was simulated according to the behavior of dispatchers under various situations that different types of delay occurred and different strategies were applied. The analysis results of quantity of delayed trains and delay time showed that： 1） The high-speed trains had greater anti-turbulence ability. The better result could be achieved if all trains ran by the existing order. 2） If the middle-speed trains were prohibited to influence the high-speed trains, they would have poor anti-turbulence ability and the trains with longer remained distance and the punctual trains should have greater priority. On the contrary, their anti-turbulence ability would increase remarkably. At the same time, the influence on high-speed trains would be quit little if only the time that high-speed trains could be postponed was less than headway time between them.
