摘　　要：针对目前国内城市轨道交通分散式供电系统仿真研究的现状,基于牵引计算与供电仿真计算软件(DCTPS)建立城市轨道交通分散式供电系统供电能力仿真评估模型,实现对直流牵引供电系统输出电压、母线载流量的仿真分析。以北京地铁8号线为研究对象,通过仿真计算不同情况下100 s发车间隔运行需求,结果表明:北京地铁8号线供电系统在正常状态下基本满足100 s发车间隔运行需求;在牵引整流单机组、牵引所解列大双边、开闭所单电源、开闭所解列等运行情况下,供电系统均无法完整满足全线100 s发车间隔运行需求。In view of the current development of the simulation research of decentralized power supply system of urban rail transit in China,a simulation evaluation model of power supply capacity of decentralized power supply system of urban rail transit is established based on the traction calculation and power supply simulation calculation software(DCTPS)to realize the simulation analysis of output voltage and busbar load capacity of DC traction power supply system.The article takes Beijing Metro Line 8 as the research object and calculates the operation demand of 100s interval under different conditions through simulation.The results show that the power supply system of Beijing Metro Line 8 basically meets the operation demand of 100s interval under normal condition.The results show that the power supply system of Beijing Metro Line 8 can basically meet the requirements of 100s interval operation under normal condition,but the power supply system cannot completely meet the requirements of 100s interval operation under the operating conditions of single unit of traction rectifier,single power supply of traction station,single power supply of opening and closing station and opening and closing station.
