Influencia de la estimación de demanda en las pérdidas en transformadores del sistema de distribución

Abstract

Technical losses in the distribution transformers represent the greater weight component of themselves, thinking about it the EEQ proposes the reduction of this losses modifying the norm for sizing transformers. Replacing a scheme based on the criteria of each designer, for one that considers strata (product of consumption measurements of neighboring customers). This document shows a computation of the demand that would have been estimated, using the previous norm, and of its consequent installed power; later calculate the losses in the aforementioned scenario and compare them with the losses in the real scenario (measured with the current standard). For the development of the work three cases of study are considered, raised from the most detailed in a specific transformer, passing through a sample of 3 feeders to reach the entire EEQ. Considering just transformers that serve residential loads that entered within the analysis period (years since the current standard is fully applied until the previous year of the entry of electric cooking into the design standard is considered).
