摘要
数据中心机房UPS供电系统可靠性要求越来越高,系统的可靠性和可用性一直是运维人员关注和重视的问题。本文从常见的二总线供电系统和三总线供电系统为例,进行了系统的可靠度与可用性对比分析和计算。再将降UPS容量的三总线供电系统进行了分析,其为典型的表决模型2/3(G)模型,降UPS容量的三总线供电系统的可靠度与可用性比二总线供电系统略高、又比三总线供电系统略低,正常工作时单台UPS负载率66.7%为最高,且投资成本适中,可以作为数据中心供电系统的首选。
The reliability requirement of UPS power supply system in data center is getting higher and higher.The reliability and availability of UPS power supply system have always been the focus of operation and maintenance personnel.In this paper,the reliability and availability of two-bus power supply system and three-bus power supply system are compared and analyzed.Then the three-bus power supply system with reduced UPS capacity is analyzed,which is a typical voting model 2/3(G)model.The reliability and availability of the three-bus power supply system with reduced UPS capacity are slightly higher than the two-bus power supply system and slightly lower than the three-bus power supply system.The load rate that is 66.7%of a single UPS is the highest in normal operation,and the investment cost is moderate,so it can be the first choice of power supply system in data center.
