Study of the Behavior of an Electric Power Generation System with AGM Battery Storage Using Sankey Diagrams

In agroindustrial processes, it is necessary to meet an electrical demand through sustainable processes in isolated regions that require a certain degree of self-sufficiency. An analysis of energy efficiency is carried out on a system that includes a 110 V electric generator powered by Natural Gas, an AC-DC transformer, and AGM batteries. These components were instrumented to collect data on fuel consumption, current, and voltage. The behavior of the generator was analyzed under varying loads, and an assessment of the system’s efficiency was performed using a direct method based on the first law of thermodynamics. This assessment is represented using Sankey diagrams, which helped determine the magnitude of losses attributed to the generator and the transformer. Suggestions are provided regarding the influence of the equipment on the energy losses for upcoming installations that aim to enhance the efficiency achieved within a commercial system.
