摘要:

区间运行时间和操纵方法是实现高速列车节能运行的两个重要方面.本文构建了可调整区间运行冗余时间的高速列车多区间节能操纵模型.考虑到高铁枢纽车站和非枢纽站对列车到达时刻准点性的要求程度不同,模型中增加了枢纽车站的列车到达时刻与列车运行图定到达时刻一致性约束,以及非枢纽车站的列车到达时刻在一定时间范围内的约束.为了避免解空间中不满足定时约束的不可行解的数量影响算法效率,设计了一种三层编码的遗传算法来求解模型.通过1条包含3个枢纽车站、3个非枢纽车站的高速铁路线路验证,结果表明,本文所提出的高速列车多区间节能操纵方法能够保证枢纽车站列车到达时刻不变,非枢纽车站列车到达时刻在一定时间范围内变换时,求得多个区间的列车最优节能操纵速度轨迹.与基于牵引—惰行控制方法和单区间节能操纵方法在图定运行时分下的计算结果相比,本文所提出的方法节能率分别超过16%和4%.

Abstract:

The running time and operation method are two important factors for realizing high-speed train energysaving operation. In this paper, a multi-interstation energy-saving operation method for high-speed train with adjustable running time supplement is constructed. Considering the requirement difference in the arrival time of high-speed train arriving at hub station and non-hub station, the model added to the constraint that the train arrival time is the same as the fixed arrival time in timetabling for hub station, and the constraints in the time range of the arrival time of the train arriving at non-hub station. In order to avoid the situation that a number of unfeasible solutions unsatisfied the timing constraints in the solution space might have defect on the algorithm efficiency, a three layer coded genetic algorithm is designed to solve the model in the paper. Through the verification of a highspeed railway line including 3 hub stations and 3 non-hub stations, the results show that the multi-interstation energy-saving operation method for high-speed train proposed in the paper could obtain the optimal multiinterstation energy-saving speed trajectory, when ensure that the arrival time of hub station is the same as the time in timetabling and the arrival time of the non-hub train station is within a certain time range. Compared with the calculation results based on the acceleration-cruising method and single interstation energy-saving operation method in the paper under the running time in timetabling, the proposed method could save more than 16% and 4% energy respectively.
