Abstract

The invention discloses a shared storage battery pack based distributed DC power supply system which uses a DC power supply device and comprises a main station DC power supply system and at least one secondary station DC power supply system, wherein electric energy is transmitted between the main station DC power supply system and the secondary station DC power supply system via a power transmission line, a storage battery is internally arranged in the main station DC power supply system, the shared storage battery pack based distributed DC power supply system is characterized in that the DC power supply device is arranged in the secondary station DC power supply system, and / or the DC power supply device is arranged in the main station DC power supply device. With the adoption of the shared storage battery pack based distributed DC power supply system, disclosed by the invention, since a secondary station can be provided with no storage battery, the operation cost and the risk of storage battery stolen can be reduced to a certain extent; and the secondary station is not provided with the storage battery, the station can work at a wider temperature range, the application of an air conditioner is reduced, and electric energy loss is reduced.

Description

technical field [0001] The invention relates to a distributed DC power supply system and method based on a shared storage battery pack, and belongs to the technical field of communication base station power supply equipment. Background technique [0002] At present, it is quite common in China to have multiple base stations belonging to different communication operators in a certain area. Here, the base stations within a radius of 500 meters are collectively referred to as "adjacent" base stations. Each base station has independent utility power introduction, DC power supply, storage battery, air conditioner and other supporting facilities. For China Tower Corporation, which owns the property rights of all supporting facilities of base stations in China, the "excessive" configuration of switching power supplies, batteries, air conditioners and other supporting equipment in adjacent base stations has significantly increased power consumption, especially batteries have strict ...
