摘要
目前大型数据中心主流不间断电源技术包括UPS和HVDC等。随着模块化建设理念的推进,出现了预制式10 kV输入不间断电源技术。本文从交流和直流两个维度分别对不间断电源技术路线进行理论对比分析,再针对2N UPS、2N 240 V直流、2N预制式10 kV输入交流电源、2N预制式10 kV输入直流电源这4种技术,从系统配置及架构、建设成本、占地面积和运营成本等方面进行案例对比分析,为新建数据中心项目提供参考。
At present,the mainstream uninterruptible power supply technologies in large data centers include UPS,HVDC,etc.With the advancement of modular construction concepts,10 kV prefabricated input uninterruptible power supply technology has entered the public's vision.In this paper,the technology route of uninterruptible power supply is analyzed theoretically from AC and DC dimensions;Further comparative analysis of four technologies,2N UPS,2N 240 V DC,2N 10 kV prefabricated input AC power supply,and 2N 10 kV prefabricated input DC power supply,will be conducted from the aspects of system configuration and architecture,construction cost,floor area,and operating cost,providing reference for new data center projects.
