摘　　要：城轨列车频繁启停造成大量制动能量反馈至牵引网,使牵引网电压大幅度波动,严重影响牵引网电压质量。首先以南京地铁1号线列车基本参数为例,通过运动学方式定量分析1号线列车启停过程,结合列车牵引/制动特性曲线对列车的能量进行分析,基于列车受力情况计算牵引/制动时吸收/回馈的能量,最后搭建仿真模型分析城轨列车启停时对牵引网电压的冲击。The frequent start and stop of urban rail trains causes a large amount of braking energy to be fed back to the traction network,which results in large voltage fluctuations and seriously affects the voltage quality of the traction network.By taking the basic parameters of the train of Nanjing Metro Line 1 as an example,this paper first quantitatively and kinematically analyzes the starting and stopping process of the train,and investigates energy of train in combination with the traction/braking characteristic curve.Then it calculates the absorbed/feedback energy during traction/braking based on the forces affecting the train.Finally a simulation model is established to analyze the impact of starting and stopping of urban rail train on the traction network voltage.
