Modeling of the three phase industrial loads for harmonic analysis using matlab/simulink / Mohd. Amrul Adam

In IEEE Standard 1159 - 1995, harmonics are sinusoidal voltages or currents of a periodic wave or quantity having a frequency that is an integral multiple of the fundamental frequency of the supply system. Harmonic generation can lead to serious power quality problem if it is not reduced to acceptable level. Electronic components content of non-linear loads contribute to serious harmonics injection to the main supply line. The objectives of this project are to model of a simple three phase industrial networks for purposes of studying the harmonics analysis existing within a supply network due to the use of various non-linear loads. Modeling is based on Power System Blockset (PSB) tool within the MATLAB/Simulink software, which is powerful software tool for various power engineering simulation. Various individual non-linear loads are modeled and simulated. Results from the basic model are then compared with similar model implemented using Pspice developed to ascertain its accuracy. Subsequently this basic model is being used in a simple three-phase system to study the effects of various loads on the operation of the supply network.
