数据中心机房高压直流供电模式研究

随着大数据时代的到来，数据业务快速增加，通信设备对电源系统安全供电要求不断提升；长期以来数据中心机房通信设备均由传统的交流UPS系统供电，而UPS供电模式在可靠性、安全性、经济性和设备维护等方面凸现出来的问题越来越多，加剧了数据中心机房的供电压力，增大了安全隐患。文章通过对比传统UPS供电与高压直流供电两种供电模式，分析了高压直流供电系统在数据中心机房可靠性、节能降耗、维护性方面表现出的使用优势，提出了适应数据中心机房IT设备供电需要的高压直流供电解决方案。

Research on high-voltage DC power supply mode of data center room

With the coming of the big data era, data business is growing rapidly and the communications equipment requires a more secure power supply system. For a long time, the data center room has been supplied power by the traditional AC UPS system, while the UPS power supply mode shows more and more problems such as its reliability, safety, economy and equipment maintenance which increase the potential safety hazards. By comparing the traditional UPS power supply mode with the high-voltage DC power supply mode, this paper analyzes the advantages of the latter in reliability, energy-saving and maintenance. The paper puts forward the solution which suits the needs of the IT equipment in the data center.
