摘要:
［目的］随着地铁线网的不断完善，各级供电系统开关的名称已无法准确辨别其所属系统，同时编号也出现了重复或不够用的情况，因此需对地铁供电系统开关编号进行优化。［方法］以西安地铁为例，对其供电系统开关编号方案现状进行了评估。通过与国内其他城市地铁、电气化铁路及国家电网供电系统对比，分析存在问题并提出具体解决方案。从供电系统开关编号特征入手，立足开关编号的唯一性和相关性，结合地铁线路的规划，优化供电系统开关编号，提出新型编号方式并对其进行可行性分析。［结果及结论］地铁供电系统开关编号优化方案，基本上解决了编号重复、零乱，以及条理性和规律性较差等问题，同时解决了馈线分类、母线分类、电压等级辨识等问题,保证了设备名称及其编号在各网区内的唯一性。
Abstracts:
［Objective］ With the continuous improvement of metro network, the names of switches in the power supply system at all levels can no longer accurately mark the systems they belong to, meanwhile the duplicated and insufficient numbering also occur. Therefore, it is necessary to optimize the switch numbering in metro power supply system. ［Method］ The current situation of switch numbering scheme for the power supply system in Xi’an Metro, for example, is evaluated. Compared with the power supply systems for metros, electrified railways and the State Grid in other cities of China, the problems existing in the scheme are analyzed and specific solutions proposed. Starting from the characteristics of the power supply system switch numbers, considering their uniqueness and relevance, and combined with the planning of metro lines, the power supply system switch numbers are optimized and a new numbering method is proposed based on an analysis of its feasibility. ［Result & Conclusion］ The optimized switch numbering scheme for metro power supply system largely solves the numbering problems such as duplicate, disorder, poor organization and regularity. At the same time, it also realizes feeder and busbar classification, and voltage level identification, ensuring the uniqueness of the equipment names and numbers within each network area.
