Proposta de um algoritmo para diagnosticar a qualidade de energia elétrica utilizando lógica fuzzy

Abstract

The article proposes a fuzzy logic-based algorithm to diagnose power quality in low-voltage three-phase systems using the THD (Total Harmonic Distortion) indicator. The fuzzy inference system classifies distortion levels in voltage and current, generating diagnoses such as "normal," "significant," or "critical." The method aims to assist in problem identification and decision-making to mitigate harmonic disturbances, contributing to improved power quality.
