Investigation and enhancement of power quality using active regenerative pwm harmonic filter based on artificial intelligence

Abstract

Electronic converters and power electronics gave birth to numerous newlinenew applications offering unmatched comfort flexibility and efficiency to newlinethe customers However their proliferation during the last decade is creating newlinea growing concern and generates more and more problems These electronic newlineloads not only pollute the AC distribution system with harmonic currents but newlinethey also appear to be very sensitive to the voltage distortion Then electricity newlinepower quality is becoming a major issue for utilities and for their customers newlineand both are quickly adopting the philosophy and the limits proposed by the newlinenew International Standards 519 1992 IEEE 61000 3 2 4 IEC newlineToday recent advances in power electronic technology are providing newlinean unprecedented capability for conditioning and compensating harmonic newlinedistortion generated by the non linear loads newline newline
