Abstract

The invention relates to a communication base station hybrid energy power supply system and an intelligent control method, and the system comprises a DC / DC switching power supply, the high-voltage side of the DC / DC switching power supply is connected with a high-voltage DC bus, and the high-voltage DC bus is connected with commercial power supply equipment through a first rectification module and is connected with a variable-frequency AC generator set through a second rectification 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; 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 and can control at least one power supply device to supply power to the communication base station, and when the clean energy power supply device has output, the hybrid energy controller is connected with the variable-frequency alternating-current generator set. 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 mixed energy power supply system and an intelligent control 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...
