摘　　要：针对地铁线路开通运营一段时间后列车牵引能耗趋于稳定的情况,文章基于构建的牵引能耗模型提出了优化牵引电制动特性与提高能量回馈率两种节能策略。对优化策略进行仿真研究,结果表明两种优化方案均具有牵引节能的效果。对既有地铁线路列车的牵引电制动特性进行优化,同时根据线路排车密度特点合理设置能馈装置,可起到有效牵引节能作用,并确保后续30年运营经济效益最优。Aiming at the situation that the energy consumption of train traction tends to be stable after a period of operation of subway lines,this paper proposes two energy saving strategies based on the constructed traction energy consumption model,which are optimizing the traction electric braking characteristics and improving the energy feedback rate.The simulation results of the optimization strategy show that both optimization schemes have the effect of traction energy saving.The optimization of traction electric braking characteristics of the existing subway line trains and the reasonable setting of energy feedback device according to the characteristics of the line row density can play an effective role in traction energy saving and ensure the optimal economic benefits of the subsequent 30 years of operation.
