Análise das distorções harmônicas geradas pelo acionamento de um motor elétrico através de um inversor de frequência

Abstract

Currentlythe use offrequency invertersfor drivingthree-phaseinduction machinesin theindustrial environmentis widespread. However,the drive, usuallypresent as theinput stagearectifier whose operationis likely toaffect the electric powerquality. Inthis worka frequency inverterthat feeds athree-phase electricmotoris modelled aimingto analyzethe disturbancesthatitgenerateson the grid.In this case, the disturbancescaused is the generation ofharmonic distortion, which is generated bynonlinear loads.From the data collectionand analysis, somesolutions toreduce oreven eliminatethe distortionof thegrid, which may be aharmonic filterdepending onthe data to becollected.
