摘要:

针对城市轨道交通区间运行时分要求,将列车在区间的最高运行速度、最低惰行速度作为速度参数,提出多速度参数调控的城轨列车区间运行策略优化问题。考虑线路平纵断面、列车性能等的影响,以及区间限速、运行时分限制等约束,以区间运行能耗最小化为目标,建立均布质量模型下的给定运行时分下基于多速度参数调控的列车运行节能优化策略模型,优化确定各速度参数取值和对应的区间运行控制方案,设计针对多速度参数综合调控的模拟退火求解方法。以广州地铁8号线中大-晓港为例,测算不同时分下的运行控制方案。结果表明:最高运行速度参数可有效控制区间运行时分取值;最低惰行速度的合理取值可显著降低能耗,最多可降低4.68%;列车操纵模式的确定需综合考虑区间运行时分、节能效果和惰行次数,节能操纵模式在较长运行时分下节能作用更为显著。优化结果可为城轨节能化列车运行组织提供决策支持。

Abstract:

For the urban rail transit, an optimization method is proposed for optimizing the train operation strategy on a rail section to minimize the operation energy consumption. With the requirement of the running time, we determine the train operation strategy by taking the maximum operation speed and the minimum coasting speed as the parameters (decision variables) of the speed profile. Given the running time of the rail section, an optimization model is built to solve the multiple speed parameters based on the uniform mass model of train and considers the constraints of the speed limit and running time with the influence of train performance and the line's horizontal and vertical sections. A simulated annealing algorithm is designed to solve the model and determine the value of each speed parameter with the corresponding operation control scheme. A numerical example of the section between Sun Yat- sen University station and Xiaogang station of Guangzhou metro line 8 is adopted to test the method with different running times. We found that (1) the maximum operation speed can effectively control the running time; (2) the reasonable value of the minimum coasting speed can significantly reduce energy consumption by 4.68% at most; (3) the selection of train operation mode requires comprehensive consideration of running time, energy-saving effect and coasting times, and the energy-saving operation mode has a significant effect on saving energy with a longer running time. It can be shown that this method can provide decision-making support for the train energy-saving operation organization of urban rail transit.
