Comparison of Different Filters for the Improvement of Power Quality

This paper basically deals with the purpose to increase the reliability of power system and improve the Power Quality (PQ) by using Hybrid Filter which hence also improves the Total Harmonic Distortion (THD) as per IEEE-519 Standard limits. The proposed filter estimates and mitigates the harmonics in power transmission systems because of non-linear loads. So, by using Hybrid Power Filter, THD will be checked and is compared with the THD obtained without using filter. In this paper I will also compare the results of different filters. The Simulation is performed and the results are realized in Simulink / MATLAB environment.

Keywords: hybrid filter, IEEE- 519 harmonic standard, power quality, total harmonic distortion.
