高可靠度新型分散式ATS

New Distributed ATS with High Reliability

由于科技的进步,改变了人类的生活方式,对于信息的储存、运算、传输的需求日益增加,于是带动大型数据中心(Data Center)的建置需求,而在数据中心的运行中,最重要的要求是持续不间断的提供服务。要满足此要求,最基本的便是稳定不间断的电源,一旦电源中断,所造成的经济损失将是非常可观。为了有持续不间断的电源,除了不间断电源(UPS)系统外,有时还会通过两路馈线,提高电源系统的可靠度。此时,最常使用的是自动切换开关(ATS,Automatic Transfer Switch)。本文针对分散式ATS进行介绍,并说明传统使用继电器之ATS应用,在现今信息设备可能产生的问题,提出相应的解决方案。

People’s life is changed by the development of technology with an increasing demand for the storage, operation and transmission of information, leading to the construction requirement of large data center. As for the operation of data center, the most important is to provide service continuously. To meet the need, the most fundamental is the stable and uninterruptible power. That is to say, a power failure will causes great economic loss. Thus, apart from UPS, two feeders are used to enhance the reliability of power system. At this point, the most commonly used is ATS（Automatic Transfer Switch）. This paper introduces the distributed ATS and explains the problems of ATS in traditional electric relays that might arise in modern information facilities. In addition, corresponding solutions are presented.
