摘要 目前,普遍采用单向导通装置减少地铁车辆段杂散电流,但车辆段杂散电流问题依旧突出。本文对正线段和车辆段进行建模仿真,通过机车牵引计算得到机车取流与时间的关系,将机车取流代入单向导通装置处的电阻网络模型,模拟机车处于不同工况时对车辆段轨道电压、电流及杂散电流的影响,并对车辆段杂散电流产生的原因进行分析,就此原因对传统单向导通装置进行优化改进,采用大功率集成门极换流晶闸管(IGCT)作为新式智能单向导通装置控制器件,在满足地铁复杂运行环境的同时大大提高了单向导通装置的可靠性,还可有效降低车辆段杂散电流。

Abstract:One-way conduction devices are widely used to reduce the stray current in the depot, but the problem of stray current in the depot is still prominent. In this paper, the main line segment and the depot are modeled and simulated. The relationship between the locomotive flow and time is obtained through the locomotive traction calculation, and the locomotive flow is brought into the resistance network model at the one-way conduction device to simulate the locomotive in different working conditions. The influence of voltage, current and stray current is analyzed, and the causes of stray current in the depot are analyzed. For these reasons, the traditional one-way conduction device is optimized and improved, and high-power integrated gate-commutated thyristor (IGCT) is used as the new intelligent one-way conduction device control device. While satisfying the complex operating environment of the subway, the reliability of the one-way conduction device is greatly improved, and the stray current of the depot is greatly reduced.
