【摘要】：互聯(lián)網(wǎng)數(shù)據(jù)中心快速發(fā)展，但隨著氣候變暖、能源緊張等問(wèn)題的凸顯，使數(shù)據(jù)中心面臨著降低能源消耗、節(jié)約總體成本的嚴(yán)峻挑戰(zhàn)，數(shù)據(jù)中心節(jié)能受到了前所未有的關(guān)注�！熬G色數(shù)據(jù)中心”的概念在當(dāng)下顯現(xiàn)出來(lái)，這個(gè)概念也將成為數(shù)據(jù)中心新興的發(fā)展方向。 數(shù)據(jù)中心電源系統(tǒng)節(jié)能需考慮供電架構(gòu)的基礎(chǔ)上，全面考慮數(shù)據(jù)中心電源系統(tǒng)的主流設(shè)備性能，以及新興產(chǎn)品設(shè)備的技術(shù)特點(diǎn)�，F(xiàn)階段數(shù)據(jù)中心電源系統(tǒng)的應(yīng)用主要分為UPS、高壓直流、市電直供等單電源或多電源的混合供電模式。所以，對(duì)數(shù)據(jù)中心的電源系統(tǒng)進(jìn)行節(jié)能分析，，必須熟悉數(shù)據(jù)中心的電源系統(tǒng)多種供電方式。 對(duì)數(shù)據(jù)中心整體節(jié)能評(píng)價(jià)指標(biāo)PUE中供電因子的計(jì)算與分析，使得節(jié)能分析能夠定量直觀地表達(dá)。本文對(duì)數(shù)據(jù)中心幾種常見(jiàn)的電源進(jìn)行節(jié)能分析，包括市電直供電源，高壓直流電源，高頻UPS電源，工頻UPS電源。同時(shí)，以曲線圖的方式進(jìn)行節(jié)能對(duì)比分析。 經(jīng)過(guò)對(duì)比分析，得出以下結(jié)論： （1）工頻機(jī)UPS效率低，節(jié)能效果差； （2） HVDC普通模塊效率高于工頻機(jī)UPS，節(jié)能效果一般； （3）高頻機(jī)UPS整機(jī)效率較高于HVDC普通模塊，節(jié)能效果較優(yōu)； （4）新一代HVDC模塊效率較高于高頻機(jī)UPS節(jié)能效果優(yōu)； （5）市電直供方式節(jié)能效果最優(yōu)； （6）隨著高壓直流的技術(shù)迅速發(fā)展與市電可靠性的提高，市電直供與新一代HVDC模塊組成的系統(tǒng)互為備份的供電方式為數(shù)據(jù)中心供電，則可以提高系統(tǒng)可靠性。高壓直流電源系統(tǒng)可能在以后成為的數(shù)據(jù)中心電源系統(tǒng)的主流設(shè)備。
[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.
