Steps to Find the Source of Harmonics

Published by David Horning, November 2014. Power Monitors, Inc., White Paper: Steps to Find the Source of Harmonics Abstract. Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics. Any nonlinear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidalContinue reading “Steps to Find the Source of Harmonics”

ADALINE Harmonics Extraction Algorithm applied to a Shunt Active Power Filter based on an Adaptive Fuzzy Hysteresis Current Control and a Fuzzy DC Voltage Controller

Published by Noureddine KHENFAR, Abdelhafid SEMMAH, Mohamed KADEM, Djillali Liabes University of Sidi Bel Abbes, Algeria. Abstract. This paper deals with the use of an adaptive linear (ADALINE) neural network in a harmonic extraction algorithm based on the calculation of instantaneous active and reactive powers.
