摘要
地铁主变压器其容量的选定对工程建设投资具有重大影响,如容量确定准确、严谨,不仅可以减少工程投资,还可以给将来的运营管理带来诸多好处,从而降低运营费用.本文采用电网趋势计算解析法进行分析,并结合实际案例,通过阐述城市轨道交通供电系统构成及各子系统的运行方式,提出一种地铁线路供电系统主变压器容量计算方法,以期为其他城市轨道交通工程提供参考,为供电系统容量确定提供途径和策略.
Abstract
The selection of the capacity of the main transformer of the subway has a great impact on the project construction investment.Accurately and rigorously determining the capacity of the main transformer of the subway can not only reduce the project investment,but also facilitate the future operation and management,thereby reducing the operating cost.Based on the analysis method of power grid trend calculation and combined with actual cases,this paper proposed a calculation method for the main transformer capacity of subway power supply system by expounding the composition of power supply system in subway and the operation mode of each subsystem,expecting to provide a reference for other urban rail transit projects,and provide ways and strategies for determining the capacity of power supply system.
