Avaliação de impactos harmônicos na rede elétrica através dos indicadores THD e Fator de Potência utilizando Lógica Fuzzy

Abstract

The study proposes an analysis of power quality in low-voltage three-phase systems using THD (Total Harmonic Distortion) and Power Factor indicators, based on a Fuzzy inference system. The method integrates expert knowledge and current standards to classify harmonic distortions and energy efficiency, avoiding manual regulation checks. Results demonstrate the system's effectiveness in identifying critical conditions, such as high THD and low Power Factor, recommending corrective actions.
