Análisis del impacto de luminarias led dimerizables residenciales en la calidad del producto en una red eléctrica de bajo voltaje.

Abstract

The purpose of this degree project is to determine the impact provoked by dimmable LED lamps used in residential applications, in the electrical product quality, especially the harmonic current injection. The utilization of these type of lamps, is going to increase considerably in the next years, due to the energy savings achieved with the dimmable LED lamps system. Laboratory measurements were performed to lamps form different brands and wattages in order to estimate the influence in the harmonic current injection. Moreover, three samples with different power rating were made for each lamp, with the objective of analyzing the harmonic distortion caused by the dimming operation. For the realization of this degree project, the artificial illumination systems, for two representative apartments, were designed using the software DIALux Evo. The design made it possible to calculate the number of lamps needed for each apartment and the energy consumption estimated per year due to the illumination systems. Based on this, mitigation measurements for the harmonic currents provoked by dimmable LED lamps were proposed. Furthermore, the technical and economic analysis for the installation of low passive filters in the illumination systems of each apartment was developed, in order to establish its viability.
