IEEE Standard 519-92 and the harmonic currentes caused by the inverter fed induction motor

This work presents an analysis of the line current harmonic currents created by the three-phase induction motor fed by a frequency inverter under the eyes of the IEEE Standard 519-92. In order to obtain the line current waveform at the supply side, a MATLAB/SIMULINK model of the whole system was developed. Aiming to validate the developed model, simulation results are presented and compared to the experimental ones. In addition to this, an analysis of the supply side line current harmonics was carried out. The results reveal that the Total Harmonic Distortion levels are above the limits established by the IEEE 519-92 Standard.
