Mathematical Modelling of the Power Supply System of a Mobile Communication Base Station

The Stable operation of mobile communication base stations depends on a continuous and reliable power supply. Power outages can lead to a decrease in communication quality or even complete service interruptions, negatively affecting users and threatening system reliability. Therefore, there is a growing need for energy management approaches based on mathematical modelling to ensure an uninterrupted power supply and improve overall system efficiency. In this article, a mathematical model of the power supply system for a mobile communication base station is developed. Based on the developed mathematical model, the mobile communication base station power supply system was simulated in the Proteus Professional 8.17 SP2 program. The simulation model enabled the simulation of the power source control system under various operating conditions, allowing for the evaluation and analysis of the power supply sources based on these conditions. Based on this model, experimental tests were conducted. The results of these tests demonstrated that the model is capable of providing a rapid response to power interruptions in the base stations, depending on the status of the energy sources, thereby ensuring an uninterrupted power supply. It was also found that utilizing supercapacitors as a primary power source during interruptions reduced the response time by a factor of 10.
