数据中心UPS供电系统中并机台数与可靠性的关系分析

Analysis of the Relationship Between the Number of Parallel Units and Reliability in Data Center UPS System

本文基于串联、并联及串并联系统的可靠性数学模型,研究了影响UPS并机系统全供电链路的可靠性因素,给出了UPS(/V+1)并机系统可靠性分析的数学模型,并定量分析了UPS(/V+1)并机系统中并机数量、并机控制软件和并机连接硬件对系统可靠性的影响,最后给出了提高UPS并机系统可靠性的方法。

rThis paper studies the factors that affectthe reliability of the full power supply link of UPS parallel systemsbased on the reliability mathematical models of series,parallel and series-parallel systems.The mathematical model for the reliability analysis of the UPS(N+l)parallel system is given,and the influence of the number of parallel units,parallel control software,and parallel connection hardware on the reliability is quantitatively analyzed.Also,the method to improve the reliability of the UPS parallel system are presented.
