IMPROVEMENT OF POWER QUALITY USING SERIES ACTIVE POWER FILTER

Archana Patnaik, R.K.Sharma

Abstract: This paper deals with the design and implementation of series active power filter for the improvement of power quality. In power system there is a nonlinear load which seems to be the prime sources of harmonic distortion. A dissimilar type of load creates nonsinusoidal current from the mains, which give rise to harmonic distortion and affect the power quality. Classic filters may not have satisfactory solutions but series active filter give quite better results and is utilized for the mitigation of harmonics and it also reduces the THD level. Results obtained shows that this scheme is able to mitigate the harmonic problem and can improve the quality of power. This is done by simulation using MATLAB software.

Keywords: Series Active Power Filter(SPAF), Nonlinear load, Power quality, Total Harmonic Distortion(THD).
