摘要: 在铁路长大坡道线路场景下,列车运行过程存在持续时间较长的牵引和制动阶段,通过充分考虑同一供电分区内牵引阶段与制动阶段列车工况重叠,能为列车节能运行提供有利条件。首先,基于长大坡道线路特点,分析列车到发时刻对工况重叠的影响;其次,为避免供电冲突,考虑同一供电分区维修天窗起止时刻相同,并综合考虑列车运行与维修天窗开设等约束,构建以列车工况重叠时间最大化,总旅行时间最小化为优化目标的混合整数规划模型,基于模型特点运用ε-约束法和GUROBI求解。最后,通过案例验证模型和算法的有效性。结果表明,本文设计的算法能有效求解案例,与优化前相比,列车总工况重叠时间增加了24.39%。研究成果能为长大坡道线路运输组织决策过程提供科学参考。

Abstract: In the context of railway lines with long and steep gradients, the train operation process involves traction and braking stages that last for a relatively long time. By fully considering the overlap of train working conditions between the traction stage and the braking stage within the same power supply section, favorable conditions can be provided for the energy-saving operation of trains. Firstly, based on the characteristics of long and steep gradient lines, the impact of train arrival and departure times on the overlap of working conditions is analyzed. Secondly, to avoid power supply conflicts, assuming that the start and end times of maintenance windows in the same power supply section are synchronized, a mixed-integer programming model is constructed, incorporating the constraints of train operation and maintenance window opening comprehensively. The objective of model is to maximize the train working condition overlap time while minimizing the total travel time. Based on the characteristics of the model, the ε-constraint method and GUROBI are used for solution. The effectiveness of the model and algorithm is verified through a case study. The results show that the algorithm can effectively solve the problem, increasing the total overlap time of train working conditions by 24.39% compared to pre-optimization. The research results can provide a reference for the transportation organization decision-making on long and steep gradient lines.
