长沙市轨道交通2号线列车能耗分析

Energy Consumption Analysis of Changsha Rail Transit Line 2 Train

以长沙市轨道交通2号为例,分析了列车空载工况和载客工况下的能耗情况,结果表明根据列车能耗系统的实时统计数据核实列车能耗的方式是可靠的。在此基础上,计算分析了列车运行过程中乘客总体重的能耗,与列车自重能耗相比,列车自重能耗在列车总能耗中占很大的比重,因此:合理地降低车辆自重将成为今后车辆设计的重要课题,根据线路客流量特点制定大小交路时刻表将成为城市轨道交通运营公司降低运营成本的研究方向。

Taking Changsha rail transit line 2 as an example,the energy consumption of the train under conditions of both no-load and carrying passenger were analyzed.The results show that it is reliable to verify the energy consumption of the train according to the real-time statistical data from the train energy consumption system.On this basis,the energy consumption of passengers in the process of train operation was calculated and analyzed,which was compared with the energy consumption of train body weight.Conclusion has been reached that the energy consumption of train body weight accounts for a large proportion in the total energy consumption of the train.Therefore,reducing the vehicle self weight reasonably will become an important topic for vehicle design in the future,and formulating the schedule for both full-length and short-turn operation according to the characteristics of line passenger flow will become the research direction for urban rail transit operation companies to lower the operational cost.
