摘　　要：分析了目前国内城市轨道交通交直流混合供电系统仿真研究的发展情况,基于PSCAD仿真软件建立了城市轨道交通交直流混合供电系统的主变电站、整流变压器和整流器等的仿真模型,实现了对直流牵引供电系统输出电压的仿真分析。通过仿真计算不同牵引变电站的输出电压波形,对比分析了牵引直流侧输出电压的差异性,并通过直流母线实际输出电压波形的对比分析,验证了仿真模型的有效性。The application of AC/DC hybrid simulation in current urban rail system of China is analyzed,an AC/DC traction simulation model for metro power supply network,including the main substation,rectifier transformer and rectifier based on PSCAD(power systems computer aided design)software is established,and the simulation analysis of output voltage of DC traction power supply system is realized.Then,the output voltage waveforms of different traction substations are calculated by simulation,the differences of output voltage from traction DC side are comparatively analyzed,and the effectiveness of simulation system is verified through the actual output voltage waveforms of DC bus.
