摘要:
［目的］受电弓故障会造成列车牵引能力的丢失，严重影响列车的正常运行。为了改善列车同一辆车上两架受电弓碳滑板磨耗不均的情况，提出一种基于列车控制与管理系统的双受电弓主动选择控制方案。［方法］介绍了城市轨道交通双受电弓控制技术的现状；分析了受电弓碳滑板的磨耗原因；介绍了基于列车控制与管理系统的双受电弓主动选择控制方案的原理及受电弓的控制流程。［结果及结论］根据碳滑板磨耗算法，所提受电弓主动控制方案能够综合计算碳滑板的热磨耗和机械磨耗程度，实时自动评估同一辆车上两架受电弓碳滑板的磨耗程度，最终使列车自动选择升起碳滑板磨耗较小的受电弓。通过所提受电弓主动选择控制方案的逻辑判断与执行，可以提高受电弓控制的智能化程度，同步两架受电弓碳滑板的更换周期，降低受电弓的维护成本。
Abstracts:
［Objective］ Pantograph malfunctions can result in the loss of train traction capability, significantly impacting the normal operation of train. To address uneven carbon slide wear of two pantographs on the same vehicle of a train, a control scheme for active selection of dual-pantograph based on TCMS (train control and management system) is proposed.［Method］ The current state of dual-pantograph control technology in urban rail transit is introduced, the reasons for pantograph carbon slide wear are analyzed, and the principles and pantograph control process in the dual-pantograph active selection control scheme based on TCMS are presented. ［Result & Conclusion］ Utilizing a carbon slide wear algorithm, the proposed pantograph active control scheme can comprehensively calculate the thermal and mechanical wear degree of carbon slides, automatically assess the wear degrees of two pantograph carbon slides on the same vehicle in real-time, and ultimately enables the train to automatically select the pantograph with less carbon slide wear. Through the logical judgment and execution of the proposed pantograph active selection control scheme, the intelligence degree of pantograph control is enhanced, synchronizing the replacement cycles of carbon slides on both pantographs and reducing the pantograph maintenance costs.
