Harmonic Impact analysis coming from the manufacturing processes of a Eletroeletrônica Industry Using KDD and Decision Trees.

Disponível em: http://www.itegam-jetia.org.https://rigalileo.itegam.org.br/handle/123456789/1136The 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.pdf.Qualidade de energiaDistorção harmônica total de tensão (THDv)Árvores de decisãoCargas não linearesProcesso de descoberta de conhecimento (KDD)ArtigoEngenharia Elétrica
