Problems solved by technology

In addition, at present, base stations and computer rooms basically need one or more cabinets next to or inside for equipment installation and power backup. However, in densely populated areas such as old urban areas, it is impossible to have enough flat ground for placing cabinets next to each base station.
The one-site-one-backup power solution can be better matched with the technical solution that each base station has BBU, RRU, and antenna, but it is not suitable for a macro station (equipped with BBU) with multiple micro stations (without BBU equipment) power supply Require

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0031] In one embodiment, such as figure 1 As shown, a communication base station power supply device is provided, including: a centralized power distribution cabinet 100 and pole-mounted power distribution cabinets 200 distributed in corresponding antenna units of each base station.

[0032] It is worth noting that the pole-mounted power distribution cabinet 200 refers to the equipment installed corresponding to the base station antenna unit. Each antenna unit is equipped with a pole-mounted power distribution cabinet. In addition, for a macro base station, one macro base...

Abstract

The invention relates to a communication base station power supply device, method and system. The device comprises a centralized power distribution cabinet and pole-mounted power distribution cabinetsdistributed at corresponding antenna units of each base station. The centralized power distribution cabinet includes a centralized baseband processing unit and a centralized power supply. The centralized baseband processing unit and the antenna unit are communicatively connected. The centralized power supply includes a battery pack and a bi-directional converter. The bi-directional converter is used to convert alternating current mains power into high-voltage direct current and charge the battery pack through the high-voltage direct current. The pole-mounted power distribution cabinets are connected with the centralized power distribution cabinet through alternating current cables and direct current cables respectively. The method can be used to improve the power supply efficiency of a base station.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a communication base station power supply device, method and system. Background technique [0002] With the advent of the 5G era, new communication equipment puts forward higher requirements on the power and density of communication operators' computer rooms and base stations. Traditional base station power supply technology is no longer suitable for the construction or reconstruction of base stations and computer rooms in densely populated areas. [0003] At present, the principle of the existing DC remote technology is to carry out medium and long-distance power transmission after the original low-voltage battery platform is boosted by one-stage or multi-stage DC booster equipment. In addition, at present, base stations and computer rooms basically need one or more cabinets next to or inside for equipment installation and power backup. However, in densely pop...
