Abstract

Transformers are fundamental componentes energy distribution systems, especially with the evolution of smart grids, the instrumentation of this equipments should be more and more present. In this sense, mathematical models that can correctly represent their behavior are necessary, since they can compose new configurations, besides allowing analysis of their operation. In this context, this paper the mathematical modeling of the thermal behavior of an underground substation of the underground distribution system of a power utility in southern Brazil is performed. From this study, an adapted model is proposed, and its validation is performed using real operating data obtained through a remote monitoring system of an underground power distribution network. The results presented considered two seasons of the year, winter and summer, for a period of 72 hours, which allowed to predict, satisfactorily, the thermal behavior of the main components present in the
