Item Harmonic Impact analysis coming from the manufacturing processes of a Eletroeletrônica Industry Using KDD and Decision Trees(INSTITUTO DE TECNOLOGIA, 2015) NOGUEIRA, Rildo de Mendonça; OLIVEIRA, Edson Farias de; SILVA, Waterloo Ferreira da; SANTANA, Ádamo L.; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota; Profa. Dra. Maria Adrina Paixão de Souza da Silva.The study analyzes the impact of harmonic distortions generated by non-linear loads (computers, notebooks, and tablets) on the electrical grid of an electronics industry in Manaus. Using the KDD (Knowledge Discovery in Databases) methodology and decision trees, data were collected over a week at different points in the production process. The results identified that the 5th and 7th order harmonics, originating from the tablet production line, contributed the most to the total harmonic distortion of voltage (THDv) at the common coupling point (PCC). The decision tree technique proved effective in classifying and prioritizing distortion sources, aiding in decision-making for impact mitigation.Item Análisis de los Impactos Armónicos en la industria de la electrónica utilizando árboles de decisión.(Instituto de Tecnologia, 2012) NOGUEIRA, Rildo de Mendonça; OLIVEIRA, Edson Farias de; SILVA, Waterloo Ferreira da; SANTANA, Ádamo L.; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota.; BRASIL, Davi do Socorro BarrosThis study analyzes the impacts of current harmonics on the electrical grid of an electronics industry in the Manaus Industrial Park, focusing on the manufacturing of computers, notebooks, and tablets. Using power quality analyzers and decision tree techniques, the work quantifies the total harmonic distortion (THD) and identifies the most impactful harmonics, such as the 5th and 7th orders, generated by non-linear loads. The results demonstrate the effectiveness of the applied methodology to anticipate future regulations and improve energy quality.
