TOSTES, Maria Emília de Lima2025-03-172015https://rigalileo.itegam.org.br/handle/123456789/709Power Quality (PQ) is constantly the subject of studies, especially in the industrial sector, where large loads of electrical systems are concentrated. With the evolution of industrial processes and the introduction of new technologies, electronic equipment that generates disturbances in the systems has been added, affecting the quality of electricity. This work analyzes the harmonic impacts in an electronics manufacturing industry in the Manaus Industrial Pole (PIM), using data mining techniques and decision trees to monitor and diagnose coupling points and processes that present significant harmonic content. The objective is to identify and quantify the levels of harmonic distortions, avoiding regulatory penalties and improving the quality of electrical energy.Inteligência ComputacionalMineração de DadosDistorções HarmônicasQualidade da Energia ElétricaÁrvores de Decisãopdf.Engenharia Elétrica e Ciência da Computação
