Hybrid energy power supply device and power supply method for communication base station

Abstract

The invention relates to a hybrid energy power supply device for a communication base station, which comprises a DC / DC switching power supply, the high-voltage side of the DC / DC switching power supply is connected with a high-voltage direct-current bus, and the high-voltage direct-current bus is also connected with commercial power supply equipment through a first rectifier module and is connected with a variable-frequency alternating-current generator set through a second rectifier module; the low-voltage side of the DC / DC switching power supply is connected in parallel with a storage battery and clean energy power supply equipment, and a clean energy controller is also connected between the DC / DC switching power supply and the clean energy power supply equipment; and the hybrid energy controller is in communication connection with the DC / DC switching power supply, the clean energy controller and the variable-frequency alternating-current generator set, can control at least one power supply device to supply power to the communication base station, and can supply power to the communication base station when the clean energy power supply device has output. And enabling the clean energy power supply equipment to maintain maximum power output.

Description

technical field [0001] The invention relates to the technical field of communication base station power supply, in particular to a communication base station hybrid energy power supply device and a power supply method. Background technique [0002] With the rapid development of my country's Internet and the large-scale construction and application of 5G technology, not only will a large number of new communication base stations be built, but the original base stations will also be upgraded and improved accordingly. It is estimated that the number of 5G base stations alone will exceed 15 million in the future . [0003] And so many base stations are not only built in cities with large populations and well-developed power grids, but also cover some remote villages, towns, counties and scattered herdsmen. These remote areas are sparsely populated, far away from the power grid, and have small power loads. In addition, there are harsh natural conditions, frequent disasters, and s...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a communication base station hybrid energy power supply device and a power supply method to solve the above problems that the communication base station cannot be powered by electric energy and clean energy at the same time, and the clean energy cannot be used to the maximum extent, especially for remote The communication base stations in the area all give priority to power supply. The present invention adopts a hybrid energy composition method different from the prior art, and incorporates clean energy power supply equipment on the low-voltage side of the switching power supply, which can be automatically adjusted according to the preset logic of the hybrid energy controller. Clean energy power supply equipment always maintains the maximum power output to maximize the use of clean energy
