    摘要:

    与4G通讯相比,5G通讯采用大规模天线、超密集组网、高频通讯等关键技术使性能大幅提升,但也使5G单个基站功耗增加,站点数倍增,因此供电需求发生变化。目前有就近供电及高压直流远供两类供电形式可满足新的供电需求,论文针对高压直流远供,梳理了关键技术的应用,并综合考量削峰填谷经济模式运行投资成本、5G基站业务负荷忙闲时段、峰谷分时电价,提出一种可行的工作模式,最后对5G基站供电的发展进行展望,为研究或设计其供电提供参考。

    Abstract:

    Compared with 4G communication, 5G communication uses key technologies such as large-scale antennas, ultra-dense networking, and high-frequency communication to greatly improve performance, resulting in increased power consumption of a single 5G base station, multiple sites, and changes in power supply requirements. At present, there are two types of power supply, i.e., nearby power supply and high-voltage DC remote power supply, which can meet the new power supply demand. Aiming at the high-voltage DC re-mote power supply, this paper combs the application of key technologies, comprehensively considers the operation investment cost of peak-shaving and valley-filling economic mode, the busy and idle period of 5G base station service load, and the time-of-use price of peak and valley, and puts forward a feasible working mode. Finally, it looks forward to the development of 5G base station power sup-ply, which provides reference for research or design of its power supply.
