铁路5G-R基站太阳能供电架构及应用

针对铁路5G专用移动通信(5G-R)系统基站布置密集、单体功耗高的特点，结合铁路无线通信的需求，研究采用太阳能(PV)为5G-R系统基站的射频拉远单元(RRU)设备供电的方案。对比分析5G-R系统RRU设备日用电规律及太阳能电池日发电规律，确定了采用太阳能结合储能与外电源的供电体系，通过比较几种太阳能电池与外电源组合供电架构的经济性与可靠性，推荐采用直流侧切换的供电架构，并进一步提出了采用直流侧智能配电的太阳能供电方案。本研究在保证5G-R系统运行安全可靠的同时，通过采用太阳能供电方式降低了铁路5G-R系统对外电源的需求。

PV power supply structure and application of 5G-R base station

According to the characteristics of dense layout and high power consumption of the 5th Generation mobile communication technology-Railway(5G-R) base stations, combined with the requirements of railway wireless communication system, the Photo-Voltaic(PV) power supply application scheme of 5G-R Remote Radio Unit(RRU) equipment is studied. By comparing and analyzing the daily power consumption of 5G-R RRU equipment and the daily power generation of solar cells, the power supply system using PV power combined with storage and external power supply is determined. By comparing the economy and reliability of several combined power supply structures of PV power and external power supply, the power supply structure switching on the Direct Current(DC) side is recommended, and the PV power supply application using DC side intelligent power distribution is proposed. In this study, while ensuring the safe and reliable operation of 5G-R system, the energy saving of railway 5G-R system is realized by using PV power supply.
