【摘要】：互联网数据中心快速发展，但随着气候变暖、能源紧张等问题的凸显，使数据中心面临着降低能源消耗、节约总体成本的严峻挑战，数据中心节能受到了前所未有的关注。“绿色数据中心”的概念在当下显现出来，这个概念也将成为数据中心新兴的发展方向。数据中心电源系统节能需考虑供电架构的基础上，全面考虑数据中心电源系统的主流设备性能，以及新兴产品设备的技术特点。现阶段数据中心电源系统的应用主要分为UPS、高压直流、市电直供等单电源或多电源的混合供电模式。所以，对数据中心的电源系统进行节能分析，，必须熟悉数据中心的电源系统多种供电方式。对数据中心整体节能评价指标PUE中供电因子的计算与分析，使得节能分析能够定量直观地表达。本文对数据中心几种常见的电源进行节能分析，包括市电直供电源，高压直流电源，高频UPS电源，工频UPS电源。同时，以曲线图的方式进行节能对比分析。经过对比分析，得出以下结论：（1）工频机UPS效率低，节能效果差；（2） HVDC普通模块效率高于工频机UPS，节能效果一般；（3）高频机UPS整机效率较高于HVDC普通模块，节能效果较优；（4）新一代HVDC模块效率较高于高频机UPS节能效果优；（5）市电直供方式节能效果最优；（6）随着高压直流的技术迅速发展与市电可靠性的提高，市电直供与新一代HVDC模块组成的系统互为备份的供电方式为数据中心供电，则可以提高系统可靠性。高压直流电源系统可能在以后成为的数据中心电源系统的主流设备。
[Abstract]:With the rapid development of Internet data center, the data center is faced with the severe challenge of reducing energy consumption and saving total cost, with the problems of global warming and energy shortage, so the energy saving of data center has been paid more attention than ever before.The concept of "green data center" appears in the present, and it will become a new developing direction of data center.On the basis of considering the power supply architecture, the main equipment performance of the data center power supply system and the technical characteristics of the new product equipment should be considered in the energy saving of the data center power supply system.At present, the application of data center power supply system is divided into single or multiple power supply modes, such as UPS, HVDC, direct power supply and so on.Therefore, energy saving analysis of the data center power supply system must be familiar with the data center power supply system.The calculation and analysis of the power supply factor in the whole energy saving evaluation index (PUE) of the data center makes the energy saving analysis express quantitatively and intuitively.This paper analyzes the energy saving of several common power sources in the data center, including municipal direct power supply, high voltage DC power supply, high frequency UPS power supply, and power frequency UPS power supply.At the same time, the comparison analysis of energy saving is carried out in the way of graph.After comparative analysis, the following conclusions are drawn:1) the efficiency of UPS of power frequency machine is low and the effect of energy saving is poor;(2) the efficiency of common HVDC module is higher than that of power frequency machine, and the energy saving effect is general.The efficiency of high frequency machine UPS is higher than that of HVDC module, and the energy saving effect is better.4) the efficiency of the new generation HVDC module is better than that of the high-frequency machine UPS.5) the energy saving effect of direct power supply is the best;6) with the rapid development of HVDC technology and the improvement of the reliability of power supply, the power supply mode, which is composed of direct power supply and new generation HVDC module, can be used to supply power to the data center, which can improve the reliability of the system.HVDC power supply system may become the mainstream equipment of data center power system in the future.
