Evaluación de la eficiencia energética en transformadores de distribución bajo diferentes condiciones de carga

Abstract

This study analyzes the energy efficiency of distribution transformers under real operating conditions, evaluating in detail the impact of load levels, core saturation, and harmonic distortion specifically current THD on the increase of electrical losses. Through the implementation of a parametric model in MATLAB, the behavior of single-phase and three-phase equipment was simulated to precisely quantify both no-load losses and load losses. The results obtained allow for the estimation of the global performance penalty under non-ideal operating scenarios, visualizing how variations in these parameters affect the equipment's operability. In this way, the research provides a solid technical foundation to optimize the management and performance of electrical systems in the face of perturbations and harmonics common in today's distribution networks.
