摘要
5G核心网采用NFV方式部署,硬件设备全面IT化,部署于云计算中心的网络云机房中。网络云机房主要有UPS(不间断电源)和HVDC(高压直流)两种供电方式。相较于传统的UPS,HVDC具有成本低、效率高、扩容便捷以及可维护性强等优势,可有效降低运营商的CAPEX和OPEX。当前,部署5G核心网的网络云机应用高压直流供电技术成为了一种发展趋势,且国内的运营商在前期针对网络云机房高压直流供电技术进行了较长时间的试验,已迈入商用应用阶段。因此,从高压直流供电系统原理出发,分析供电原理和网络云机房的供电可行性。
5G core network is deployed in NFV mode,and the hardware equipment has been fully it based,which is deployed in the network cloud room of cloud computing center.There are two main power supply modes in the network cloud room:UPS and HVDC.Compared with the traditional UPS,HVDC has the advantages of low cost,high efficiency,convenient expansion and strong maintainability,which can effectively reduce the CAPEX and OPEX of operators.In the age of 5G,it will be a development trend to deploy the HVDC power supply technology in the network cloud room with 5G core network,moreover,domestic operators have carried out a long-term test on the HVDC power supply technology of the network cloud room in the early stage,and have entered the commercial application stage.Based on this,mainly focuses on the principle of HVDC power supply system,starting from the principle of HVDC power supply system,this paper analyzes the power supply principle and the power supply feasibility of network cloud room.
