摘要
不间断供电电源(UPS)是一种提供不间断、高质量电力的电源系统,其可靠性直接关系到计算机系统和网络应用中负载软硬件的好坏,因此对其可靠性进行研究是非常重要的。建立了三种常见的UPS连接方式可靠度指数分布模型,定量评估了系统的可靠性,提出了提高可靠性应采取的措施。对工程实践具有一定的指导意义。
The uninterruptible power system（UPS） was the power system that provided the uninterrupted and high-quality electric,its reliability was directly related to the application of the hardware and software in computer system and network,so it was very important to study the reliability of UPS.Three common systerm reliability mod-els of UPS based on exponential distribution were established,the reliability of the systerm was quantitatively as-sessed,the measures were proposed to improve the reliability.It was meaningful to the engineering practice.
