现代数据中心供电系统规划设计（六）

Planning and Design of Power Supply Systems for Modern Data Centers （6）

在数据中心中，供电系统是基础设施最重要的子系统之一，文中将针对现代数据中心供电系统规划设计要求、数据中心供电系统存在的问题和设计理念的变化、数据中心供电系统方案的选择、对UPS设备性能指标的重新认识、系统模块化与模块化UPS、高频机型UPS将成为现代数据中心UPS设备的首选机型、直流输出DCIUPS系统的研究和应用前景、数据中心备用能源的配置、数据中心供电系统的节能设计、供配电系统设备的布局设计与安装等问题，分专题进行系统的介绍和讨论。

For tile data center, tile power supply system is one of the most important infrastructure subsystems. This paper presents systematical introduction and discussion by way of subtopics about the power supply system planning and design requirements for modern data centers, the existing problems and design concept change of the data center power supply system （DCPSS）, the selection of DCPSS solutions, the new understanding of UPS performance indices, the system modularization and modular UPS, the high frequency UPS preferred for modern data centers, the research and application prospects of DC-UPS systems with direct-current outputs, the configuration of data center standby power, the energy-saving design of DCPSS, the layout design and installation of power supply and distribution system equipment, etc.
