Abstract

The demand for a reliable power supply and electricity continues to increase, which has led to an increase in the production capacities of power generation units and regular utilization of the power transmission infrastructure. This in turn has resulted in significant stress on the system, which can cause issues such as sudden outages. To eliminate these problems, it is important to accurately evaluate the performance of electrical appliances. With this in mind, this paper investigates the power, runtime, and related quantities of Uninterruptible Power Supply (UPS) systems. This information can be used to understand the lifespan, safety, and efficiency of these systems. This study examines how various circuit parameters impact the runtime of a UPS system and analyzes the chronological variations of UPS system runtime using collected parametric data. It also maps the relationship between parameters, such as the temperature at the battery positive terminal, supply voltage, supply current, average power, and total energy stored in the battery with respect to the runtime of the system. Additionally, the future trends of system runtime are inferred using the stated parameters. This study also proposes new methods for assessing the effectiveness of power use and developing forecasting models with relatively small data sets. Overall, the current work offers new insights into UPS system performance and the factors contributing to chronological variations in runtime.
