摘要

数据中心是多站融合建设和研究中的重要负荷之一，为探索多站融合型数据中心的建设方向，就多站融合型数据中的交直流供电模式进行了对比分析。首先从多站融合的建设需求出发，分析了多站融合型数据中心交直流供电模式的典型架构；然后提出了一种考虑经济性、可靠性和可控性3个维度的供电模式综合评估方法，并基于该方法对所述交直流供电模式的典型架构进行了对比分析。研究结果表明，直流供电模式在经济性、可靠性和可控性等3个方面都优于交流供电模式，且随着直流设备技术的成熟，直流供电模式的各项指标有望展现更大的优势。

Abstract

Data center is one of the important loads in the multi -station integration. A comprehensive comparison between DC and AC power supply architectures is focused to consider the effect of entire power supply modes on data center. Firstly

the typical DC and AC power supply architectures are analyzed. Then

a comprehensive assessment method considering economic

reliability

and controllability is developed. Finally

the comparison of the typical architectures based on the assessment method is applied.The results show that the DC has significant advantages over AC on economic

reliability and controllability. With the development of the DC technologies

the assessment method is supposed to be applied on more scenarios or developed to make more comprehensive and specific comparison.
