摘    要:以多导体传输线模型为基础,推导了牵引变电所和分区所等值电路,构建了适用于不同结构和供电方式的牵引网统一数学模型。对列车牵引传动系统利用参数辨识的方法,建立了感应电动机并联静止负荷的数学模型,实现对列车更准确建模。以此为基础,开发了基于车网耦合潮流计算的电气化铁路牵引供电系统仿真软件。实例计算表明,该方法充分考虑列车与牵引供电网的交互影响,能够更真实地反映牵引供电系统的潮流分布,具有重要的工程应用价值。

关 键 词:牵引网模型  列车仿真  车网耦合  潮流计算  电气化铁路

Abstract:Based on the multi-conductor transmission line(MTL) model,the equivalent circuit of traction substation and sectioning post is derived,and a general mathematical model is established.This model is suitable for the analysis of traction power networks fed by different power supply modes.Parameter identification method is used to establish a model of induction motor in parallel with the static part of train’s traction and drive system to realize train’s exact modeling.On this basis,the simulation software based on coupling between train and network for traction power supply system of electric railway is developed.Calculation results of actual example show that the method fully considers interactive influence of trains and traction power supply system,and possesses good generality and reliability properties.
Keywords:traction network model  train simulation  coupling between locomotive and network  power flow calculation  electric railway
