摘要:
［目的］在城市轨道交通线路中，牵引供电设施支持列车运行的数量具有上限。当前续列车故障或者繁忙线路列车追踪密度过高时，可能导致供电臂负荷电流过大而引起电力开关跳闸，从而严重影响运营。传统的ATS(列车自动监控)系统无法智能化掌握供电系统的实时运行情况，需研究供电能力和行车的关系以实现行车动态卡控。［方法］基于供电臂供电能力分析以及列车运行曲线，提出一种行车动态卡控方法。通过对信号、供电、车辆和轨道等多专业数据进行融合分析，并结合大数据电流曲线预测模型，实现对供电负载能力的动态监测与预测。将预测的电流曲线与列车ATO(列车自动运行)运行曲线有机结合，实时调整进入当前供电臂运行的列车数，实现动态卡控列车运行。该方法在深圳地铁16号线上进行了实例验证。［结果及结论］基于供电能力的行车卡控方法通过预测列车所需取流动态调整列车运行，可有效避免因行车导致过负荷引起的供电系统跳闸故障，在保证运营效率的同时，提高了线路运营的安全性。
Abstracts:
［Objective］ In urban rail transit lines, the number of traction power supply facilities supporting train operation has an upper limit. Preceding train breakdown or overhigh train chasing density on busy routes may possibly result in overload current of the feeding section and power switch trip, seriously affecting train operation. The traditional ATS (automatic train monitoring) system is unable to intelligently control the real-time operation of the power supply system. Therefore, it is necessary to study the relation between power supply capacity and train operation to realize dynamic train operation control. ［Method］ Based on power supply capacity analysis of the feeding section and the train running curve, a dynamic train operation control method is proposed. Through fusion analysis of multi-disciplinary data such as signal, power supply, vehicle and track, and in combination with big data current curve prediction model, the dynamic monitoring and prediction of power supply load capacity is realized. The dynamic train operation control is achieved by combining the predicted current curve and the train ATO running curve, and adjusting the number of trains running in the current feeding section. The above method is verified as an example on Shenzhen Metro Line 16. ［Result & Conclusion］ The dynamic train operation control method based on power supply capacity dynamically adjusts the train operation by predicting the required current for trains, and can effectively avoid the power supply system tripping fault caused by the overload of train operation, improve the line operation safety while ensuring the operation efficiency.
