摘要
不间断电源(uninterruptible power system,UPS)是数据中心供电连续性的重要保障。根据三母线供电方案原理,提出了四母线冗余供电方案,UPS负载率从三母线方案的66.6%提升至75%,同时具备双总线系统的可靠性等级。文章提出一种大型数据中心UPS四母线冗余供电方案,该方案在不降低可靠性等级的前提下降低了建设成本,为数据中心供电系统设计提供借鉴和参考。
Uninterruptible Power System （UPS） is an important guarantee for the power supply continuity of data center. According to the principle of three bus power supply scheme, a four bus power supply scheme is put forward. UPS load rate is increased from 66.6% to 75%, and the same level of reliability as the dual bus system is ensured. This paper puts forward a kind of four bus redundant power supply scheme for large data center, which reduces the construction cost under the premise of not reducing the reliability level, and provides reference for the design of power supply system of data center.
