摘　　要：为降低数据中心电源系统建设维护成本,在数据中心建设中引入新的市电直供供电系统,该供电结构中主用供电分路使用市电直接供电至服务器端,热备供电分路使用高压直流系统作为保障供电电源。市电正常时,市电不经转换为服务器设备供电,高压直流系统不负担负载;市电故障后,分别由后备电池组和发电机组依次为服务器供电。通过现网设备实验对该供电系统进行了效果验证,该系统对降低数据中心初期建设成本及运行能耗有明显效果。In order to reduce the data center power system construction and maintenance costs, the new power system is introduced to the data center. In the new power system, urban power directly supplies power to the server devices, and HVDC system is used as the guarantee power supply. When urban power is normal,the urban power directly supplies power to the server devices, and HVDC does not output current; When urban power is in failure, the battery pack and generator will supply power to the server devices. The initial cost of construction and energy consumption will be reduced in the data center, which has been verified in the present network equipments.
