济南轨道交通R1线弱电系统不间断电源建设方案探讨

Construction of Weak Electricity System UPS for Ji'nan Rail Transit R1 Line

介绍了济南市轨道交通R1线的工程概况及建设原则,详细阐述了R1线不间断电源(UPS)建设方案,着重论述了供电方式及UPS整合方案的比选。R1线一级负荷中的特别重要负荷不整合,采用UPS分散供电方式;将ISCS(综合监控)、ACS(门禁系统)、AFC(自动售检票)、OA(协同办公)与PIS(乘客信息系统)等专业的设备进行整合,共用1套UPS;BAS(环境与设备监控系统)独立设置UPS,其设备与电源设置在ISCS设备机房。整合的负荷UPS采用双机并联冗余供电方式。计算了R1线采用UPS整合方案后的UPS容量及造价,以及机房建筑面积,计算结果显示,R1线UPS建设方案提高了供电的安全性和可靠性。

The current engineering of Ji＇nan rail transit R1 Line and the construction principle are introduced,the weak electricity system UPS is specially described with a comparison between the power supply system and the integration with UPS. By adopting UPS,ISCS （integrated supervisory control system）,ACS （access control system）, AFC （automatic fare collection）,OA （office automation） and PIS （passenger information system） could all be integrated. The capacity and cost of UPS after integration for R1 Line and the computer room area are calculated, it shows that the construction of weak electricity system UPS can improve the security and stability of R1 Line.
