A new system for distorted three-phase sinusoidal quantities measurement

In recent years. due to the wide spread of electronic power components, the waveforms of voltage and current on power lines have characteristics far different from the sinusoidal conditions. In this paper, a new system based on an algorithm allowing the determination of parameters related to each harmonic in voltage and in current on three-phase power lines, practically symmetric and balanced, is proposed. This system has been verified both by simulation and by testing with an experimental set-up reproducing distorting loads. (C) 2002 Elsevier Science Ltd. All rights reserved
