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

This paper approaches the analysis of the current distortion impact due the harmonic frequencies present at the power grid of an industry facility at Manaus during the manufacturing process of informatics devices. The reason for such frequencies to appear are the presence of non linear loads from personal computers, notebooks and tablets. The data were collected in a measurement campaign during a week, using quality energy analyzers at different production process supplied by 13,8kV and with a nominal load of 800kVA. The main objective of this paper is to present an analysis based on computational intelligence using decision tree to determine and quantify the harmonic distortions commonly present at manufacturing process of informatics industries using simultaneous measurements of voltage and current to determine which process has the biggest impact in the total harmonic distortion at the common coupling point between the factory and the energy dealers.
