摘　　要：阐述了城市配电网中轨道交通牵引供电系统建模与仿真技术研究的研究背景和意义,然后基于PSCAD软件,从配电系统侧(外部电源)、主变电所、环网电缆、牵引变电所、牵引负荷、牵引接触网、回流钢轨、滤波器等8个方面初步构建了一个城市轨道交通牵引供电系统仿真模型。最后从内电感、外电感以及总电感三个指标出发,研究了一种牵引线路电感的计算方法。At first, this paper introduced the research background and research significance of urban rail transit traction power supply system （URTI＇PSS） modeling and simulation in power distribution network. Secondly, based on PSCAD software, it presented a simulation model for URTI＇PSS from eight aspects which contained the external power supply, the main substation, ring network cable, traction substation, traction load, traction contact system, reflux rail and filter. Finally, starting from the three indices such as the internal inductance, external inductance and the total inductance, the calculation method of the traction line inductance was given.
