摘要
早期的国内地铁建设中,大多采用各弱电系统单独设置UPS电源系统的方式,这种方式在实际运营的过程中存在着维护不方便、设备重复配置、占地面积大和利用率低等问题。近年来,国内地铁行业开始对UPS进行不同程度的集中设置,但整合的范围和实施的方式均有所差异。为此,文章在性能、效率和成本等方面对比集中式UPS和传统分布式UPS的优劣性,通过调研整合范围和分析分布式UPS整合案例,提出相应的方案和建议,以供参考。
In the early domestic metro construction,each extra-low voltage system was generally equipped with UPS separately.This method has problems such as inconvenient maintenance,repeated equipment configuration,large floor space and low utilization rate during practical operation.In recent years,the domestic metro industry has begun to set up centralized UPS to varying degrees,but the scope of integration and the method of implementation are different in various metro.This article compares the advantages and disadvantages of centralized UPS and traditional distributed UPS in terms of performance,efficiency and cost,and puts forward corresponding plans and suggestions for reference by investigating the scope of integration and analyzing distributed UPS integration cases.
