COSTA JUNIOR, Carlos Tavares da2025-03-172010https://rigalileo.itegam.org.br/handle/123456789/720This work presents a solution to minimize harmonic distortion in low-voltage electrical systems through the application of passive harmonic filters and the use of fuzzy logic. The proposed algorithm detects and calculates the frequencies at which the Total Harmonic Distortion (THD) value is elevated, comparing it with a normative index. Once the need for filter application is identified, the algorithm designs the passive filter, chosen for its ease of installation and low cost. The algorithm also recalculates the THD after filter application, using fuzzy logic to classify the final result.HarmônicasFiltro HarmônicoFiltro PassivoLógica FuzzyDistorção Harmônica Total (THD)pdf.Engenharia Elétrica Sistemas de Energia Elétrica Controle e Processos Industriais
