Simulation Model for Passive Harmonic Filters Using Matlab/Simulink: A Case Study

Electrical grid power quality is a global issue. The must supply electricity at sinusoidal voltages and currents without frequency or amplitude fluctuations. Harmonics from non-linear loads change the stable reference point voltage waveform cause other problems. Harmonic reduction essential for health. electronic equipment users, manufacturers, suppliers all contribute. This article presents case analysis of plastic processing industry, which has historically struggled with difficulty related to fifth harmonic. Unwanted harmonics are reduced by using single-tuned passive filter, double-tuned second-order damped filter. total harmonic distortion almost identical, but filter provides best mitigation, meeting requirements IEE 519-1992 Standard.
