摘要
地铁弱电系统通常主要由高可靠性UPS不间断供电，为一级用电负荷。该文介绍了该弱电系统各部分的供电需求，对UPS的容量确定、电池配置参数的计算、供电运行方式与切换逻辑进行了详细描述。
A metro weak electricity system is generally powered by UPS of high reliability, a first level load of power supply. This paper introduces the power supply needs in different parts of this weak electricity system and the determination of UPS capacity, the calculation of the battery configuration parameters, the operation mode of power supply and the switching logic are described in detail.
