5G base station intelligent micro-grid multi-source power supply system

Abstract

The invention discloses a 5G base station intelligent micro-grid multi-source power supply system. A power supply side takes photovoltaic power supply as a main part and mains supply as an auxiliary part, and direct current remote power supply, energy storage batteries, charging piles and an electric vehicle are used as power supply supplementation; except for photovoltaic power supply, each power supply unit in the power supply side is bidirectionally communicated with an electric energy conversion center; and the 5G base station load is powered by the electric energy conversion center. According to the system, a flexible and efficient power supply mode in which photovoltaic power supply is used as a main mode, the mains supply is used as an auxiliary mode, and the direct-current remote supply, the energy storage batteries, the charging piles and the electric vehicle are used as supplements is adopted. Each monitoring module collects local information, carries out analysis and calculation locally, controls the operation state of local related equipment based on an analysis and calculation result, at the same time, part of the local information and the analysis and calculation result are uploaded to the cloud server through the wireless communication module, and the cloud server processes the global information of the multi-source power supply system in real time. And the execution instruction is sent to each monitoring module, and each monitoring module adjusts the operation state of local related equipment, so that safe and high-efficiency operation of the multi-source power supply system is realized.

Description

technical field [0001] The present invention relates to the technical field of 5G communication equipment, and more specifically, the present invention relates to a 5G base station smart microgrid multi-source power supply system. Background technique [0002] According to data from the Ministry of Industry and Information Technology, as of June 30, 2020, my country has built and opened more than 400,000 5G base stations, with an average of more than 15,000 new 5G base stations built every week. Although 5G network transmission is fast, the cost is higher energy consumption. According to the statistics of operators, the power consumption of 5G base stations is 3 to 4 times that of 4G. According to this power consumption comparison, it means that the electricity bill of 5G base stations will be 9 to 10 times higher than that of 4G. Such electricity consumption is undoubtedly shocking and disturbing. [0003] With the continuous development of photovoltaic power generation t...

Although 5G network transmission is fast, the cost is higher energy consumption

However, photovoltaic is an intermittent energy source, which is greatly affected by the natural environment and has many uncontrollable factors, which limits the operating efficiency of photovoltaic power generation and weakens its advantages and potential. The control strategy cannot dynamically adjust the power supply mode in real time according to the operating status of the system and local equipment, which can easily cause energy waste and have hidden dangers to system stability
