北京地铁14号线接触网供电分区布置优化方案及其优化分析

Optimization scheme of OCS power supply compartment layout for Beijing metro line 14 and its optimization analysis

为应对传统地铁接触网供电分区设计方案无法满足在供电分区发生故障或恶劣天气影响线路正常运营的情况下,最大程度维持线路运能的问题,依托北京地铁14号线,深入剖析其供电分区布置方式,并提出2种改进的设计方案,其目的是为后续地铁接触网供电分区布置的优化设计提供具有普遍适用性的建议。在分析过程中,文章全面权衡2种设计方案的优缺点、运用到既有线改造上的复杂度以及经济效益等多个维度,旨在明确并优化最终的设计方案。优化后方案需确保在地铁线路发生故障时能够有效缩小故障的影响范围,最大限度地维持运输能力,从而保障地铁供电系统的安全、可靠运行。

To cope with the issue that the traditional metro OCS power supply compartment design scheme cannot meet the requirements of maintaining the line's capacity to the maximum extent in case of power supply compartment failure or bad weather affecting the normal operation of the line,relying on the Beijing metro line 14,this article carries out in-depth analysis of its power supply compartment layout,and puts forward two kinds of improved design scheme,aiming to provide universally applicable suggestions for the design optimization of the OCS power supply compartment layout of subsequent urban rail transit.In the process of analysis,this article comprehensively weighs the advantages and disadvantages,the complexity of applying them to the transformation of existing lines and the economic benefits and other dimensions of the two design schemes,with the aim of clarifying and optimizing the final design scheme.This scheme should ensure that in the event of a metro line failure,it can effectively reduce the scope of influence of the failure,maximize the maintenance of transport capacity,so as to ensure the safe and reliable operation of the power supply system of rail transit.
