城市轨道交通能耗影响因素及测算研究

指出城市轨道交通是一种资源节约型、环境友好型的绿色公共交通方式,同时又是城市的用电大户。讨论城市轨道交通车辆能耗、车站能耗的影响因素,剖析单位车公里、单位人公里、单位吨公里等能耗指标及其特征,建立城市轨道交通线网能耗测算模型。基于各线路能耗统计数据,测算北京市轨道交通网络的全年总能耗量,分析不同线路条件下车辆能耗、车站能耗的特征和规律,为进一步优化线路规划设计、节约系统能耗等提供参考。

Study and Calculation of Influencing Factors on Urban Rail Transit Energy Consumption

Urban rail transit is a resource-saving,environment-friendly urban public traffic mode and also the main power consumer of the city. This paper analyzed the factors influencing the energy consumption of vehicles and stations of urban rail transit,studied the energy consumption indexes and their characteristics including energy consumption per vehicle per kilometer,per passenger per kilometer and per ton per kilometer,and established the energy consumption calculation model of urban rail transit network. Based on the statistical data of energy consumption of each line,the annual energy consumption of Beijing urban rail transit network was calculated,and the features and regulation of vehicle energy consumption and station energy consumption under different line conditions were summarized,which can provide guidelines for the optimization of new line planning and design to reduce energy consumption of the system.
