The an investigation of harmonic effect in industrial system equipment

Abstract

Nowadays, electricity becomes the most demand amongst all other things. Power system quality is the big concern to ensure the continuity of many electrical equipments and devices. Power system harmonic is one of the power quality issues that must be taken care of. Many power electronics devices contribute to harmonic in the system. Harmonic problem will affect both the power supply providers and also the customers. This project studied about the harmonic mitigation by the installation of passive filter using MATLAB SIMULINK software in designing customer’s electricity side and simulation for harmonic distortion analysis. Simulation was conducted with and without filter installation. Furthermore the two results obtained will be compared and analyzed. Using tools from the SIMULINK software, it is observed that the total harmonic distortion (THD) is reduced when passive filter is installed in the circuit.
