摘要
为实现城市轨道交通的节能降耗,降低运营成本,提出基于平峰时段客流特征和行车组织特点的城市轨道交通平峰节能运行图优化模型。在平峰时段,通过压缩客流量较小车站的停站时间,将富余停站时间用于列车区间运行,在保证整体列车运行周期不变的同时,实现降低列车牵引能耗的目标。建立考虑乘客服务水平的城市轨道交通平峰期节能运行图优化模型,并设计遗传算法对模型进行求解。以深圳地铁7号线上行方向为例,结果表明上行方向区间牵引总能耗整体减少87.35 kW·h,节能效率达到19.44%。研究表明在不影响乘客正常乘降列车的情况下,提出的考虑乘客服务水平的平峰节能运行图模型调整列车区间运营时间,具有显著的节能减排效果。
To achieve energy conservation and reduce the operation cost of urban rail transit,this paper proposed an optimization model of energy saving train working diagram based on the characteristics of passenger flow and traffic organization during off-peak periods.The station dwell time with small passenger flow was compressed,and the spare time was used for train running in sections,which reduced the train traction energy consumption and kept the whole train operation cycle constant.Meanwhile,the genetic algorithm was designed to solve the problem.Taking the upstream direction of Shenzhen Metro Line 7 as an example,the case analysis results show that the total traction energy consumption in the upstream direction decreases by an overall reduction of 87.35 kW·h and reaches an energy saving efficiency of 19.44%.Without affecting the normal riding of train passengers,energy saving train working diagram of urban rail transit which adjusts the operating time of train sections has a certain effect in saving energy and reducing consumption.
