| 摘 要： | 城市轨道交通普遍采用直流牵引供电系统,多变电所多列车并列运行,线路上所有变电所均有可能向各列车供电。针对多区间多列车杂散电流动态分布,建立了多电源叠加的杂散电流分布模型,仿真分析出全线杂散电流、钢轨电位、排流网对地电位等相关参数随时间、位置的变化。所提出的仿真模型及结果可有效应用于直流牵引供电系统回流参数动态规律分析。

| Abstract: | DC traction power supply system is widely used in urban rail transit system,in which all the substations are possible to provide power for all trains in operation.According to the dynamic distribution of stray current in multi trains running in multi intervals,a dynamic simulation model of stray current with multi power composition is established.In which,changes of stray current,rail potential,drainage net potential and other related parameters with time and location are simulated.The model can be effectively applied to the dynamic analysis of reflux parameters. |
