摘　　要：弓网离线对地铁安全运行带来不利影响.首先建立弓网离线牵引系统仿真模型,然后对不同时长的离线状况进行仿真,通过对离线期间牵引逆变电路的直流侧电压、IGBT电压以及电机转子电流的暂态过程进行分析,获取不同离线时长对列车牵引过程电气特性的差异化影响.研究结果对牵引系统故障诊断和维修策略制定有较好的理论指导作用.The pantograph-catenary offline has many adverse effects on the safe operation of the subway.Firstly,the simulation model of pantograph-catenary offline traction system was established,and then the offline conditions of different durations were simulated.By analyzing the transient process of the DC side voltage,IGBT voltage and motor rotor current of the traction inverter circuit during the offline period,the differential effects of different offline time lengths on the electrical characteristics of the train traction process were obtained.The results have a good theoretical guiding role for the fault diagnosis of the traction system and the formulation of maintenance strategies.
