Os Impactos na Qualidade da Energia Elétrica Oriundos das Lâmpadas Fluorescentes Compactas Instaladas no Programa Luz para Todos

Abstract

The Brazilian Federal Program "Luz para Todos" provides for the installation of 15W compact fluorescent lamps (CFLs) in rural households and underserved communities. This work evaluates the impact on power quality caused by the injection of harmonics generated by these lamps. Measurements of Total Harmonic Distortion (THD) were performed using an AC power source and a power quality analyzer. The results show that CFLs introduce significant distortions in the current, with THD up to 121.2%, which can compromise the quality of power supplied by distribution systems. The study also simulates the impact on a real distribution system of the utility CELPA, highlighting the need to review planning and sizing methodologies for electrical systems to address these disturbances.
