Abstract

An uninterruptible power supply is the most important part of the Data Center, linking between the main power supply and end sensitive load, to provide imperative protection against power disruptions. The main UPS preferred choices for protecting critical loads in Data Center are (Double Conversion Online UPS and Flywheel UPS system). But for the Data Center managers and operators selecting the right UPS for deployment can be a difficult proposition. Therefore this paper aims to provide a clearer understanding of key factors and considerations involved in selecting the right UPS system in terms of efficiency and cost. In order to clear these concerns a comparison made between Double Conversion Online UPS and Flywheel UPS system in a model of a medium size Data Center designed to provide 1500kW of cooling capacity to the Data Halls and hence support 1500kW of IT load. The electrical infrastructure topology to be adopted is `N+1' parallel redundancy configuration for each type of the UPS systems technologies.

中型数据中心双转换在线UPS与飞轮UPS的效率和成本比较

不间断电源是数据中心最重要的部分，连接主电源和终端敏感负载，提供必要的保护，防止电力中断。保护数据中心关键负载的主要UPS选择是(双转换在线UPS和飞轮UPS系统)。但是对于数据中心管理人员和运营商来说，选择合适的UPS进行部署可能是一个困难的命题。因此，本文旨在提供一个更清晰的了解的关键因素和考虑因素，涉及选择合适的UPS系统在效率和成本方面。为了解决这些问题，在一个中型数据中心的模型中，对双转换在线UPS和飞轮UPS系统进行了比较，该模型旨在为数据厅提供1500kW的冷却能力，从而支持1500kW的IT负载。对于每种类型的UPS系统技术，将采用“N+1”并联冗余配置的电气基础设施拓扑。
