A Review of Various Techniques Used for Improvement of Power Quality

Abstract

Power quality issues are becoming a major concern of today's power system engineers. Harmonics plays significant role in deteriorating power quality, called harmonic distortion. To improve power quality by compensating harmonics, various techniques are developed. This paper discusses the various techniques for improvement of power quality in electrical power system. The technique includes hysteresis current control (HCC), P-Q theory, Wavelet, Hybrid active filter (HAF), generalized reactive power theory.
