TIME DOMAIN METHOD TO DETECT HARMONIC SOURCES IN UNBALANCED POWER SYSTEMS
Massimo Aiello, Antonio Cataliotti, Valentina Cosentino, Salvatore Nuccio
Abstract:
In recent years the problem of harmonic pollution has become more urgent, because of the development in distribution systems of non linear loads that draw non-sinusoidal currents. This paper presents a time domain method for harmonics sources detection in power systems, which can be usefully applied also in presence of unbalance or asymmetry. Harmonic power flows are calculated in real time and no spectral analysis is required for the evaluation of currents amplitudes and phase angles. The development of a new instrument is described, which is able to measure several network power quality parameters; measurement accuracy is estimated and experimental results are reported.
