摘　　要：密集分布的小/微基站和Maaaive MIMO天线是5G基站的两大主要特征。随着5G大规模商用,通信基站共享需求的增加,传统的交流拉远、48 V直流远供电源系统已经不能满足5G网络设备高密度分布、网络总体能耗大幅增加的需求。为增强通信基站供电能力,进一步解决高功率密度及传输线路上的压降问题,可采用750 V高压直流电源系统供电。在现有240 V/336 V直流远供技术的基础上,提升系统工作电压至750 V,不仅可有效降低线路压降,提升供电系统能效,还可配置退役大Pack电池,实现电动汽车电池的梯次利用。Densely distributed small/micro base stations and Massive MIMO antennas are the two main features of 5G base stations.With the large-scale commercial use of 5G,the demand for communication base station sharing is increasing.The traditional AC and 48 V DC remote power supply system can no longer meet the needs of high-density distribution of 5G network equipment and a significant increase in overall network energy consumption.To enhance the power supply capacity of communication base stations,750 V high voltage DC power supply system could be used for power supply,which will further reduce the high power density and the voltage drop on the transmission line.Based on the existing 240 V/336 V DC remote power supply system,it increased the operating voltage of the system to 750 V.The system not only can effectively reduce the line voltage drop and improve the energy efficiency of the power supply system,but also can be equipped with retired large Pack batteries to realize the echelon utilization of electric vehicle batteries.
