摘要

超级电容有轨电车具有高效环保的优点，研究其多区间运行时刻表和运行策略能够进一步降低运行能耗。文章首先介绍车载超级电容能量流动模型，建立列车动力学模型与超级电容模型，以列车系统总能耗最小为目标，建立协同优化列车运行时刻表和运行策略的节能控制模型；设计动态规划算法，求解列车多区间运行时刻表和运行策略；最后通过实车线路进行仿真验证。结果表明，在各区间均采用节能运行策略，相比于标准时刻表，优化时刻表能够进一步降低运行能耗；同时分析了多区间总运行时间与能耗的关系，可综合考虑列车运行能耗与效率制定运行时间，采用协同优化方法确定时刻表与运行策略，从而达到节能的目的。

Abstract

The supercapacitor tram has the advantages of high efficiency and environmental friendly

and the study of its multi-section operating schedule and operation strategy can further reduce the operating energy consumption. Firstly

the on-board supercapacitor energy flow model was introduced

and the train dynamics model and supercapacitor model were established. With the goal of minimizing the total energy consumption of the train system

an energy-saving control model for collaboratively optimizing the train operation schedule and operation strategy was established. A dynamic programming algorithm was designed to solve the multi-section running schedule and running strategy of the train. Finally

through the simulation verification of the actual vehicle line

the results showed that the energy-saving operation strategy could be adopted in each interval. Compared with the standard timetable

the optimized timetable could further reduce the operating energy consumption; and the relationship between the total operating time and energy consumption of multiple intervals was analyzed

which can comprehensively consider the energy consumption and efficiency of train operation to set the running time

and use the collaborative optimization method to determine the timetable and operation strategy

so as to achieve the purpose of energy saving.
