The algorithm is able to detect events caused by waveform distortions and variations of the RMS values of the voltage. Detection of the RMS events is done by comparing the RMS values with certain thresholds, while detection of waveform distortions is made using an algorithm based on multiharmonic leasts-squares fitting.}, type={Artykuły / Articles}, title={Real Time PC Implementation of Power Quality Monitoring System Based on Multiharmonic Least-Squares Fitting}, URL={http://www.journals.pan.pl/Content/89818/PDF/Journal10178-VolumeXVIII%20Issue4_03paper.pdf}, doi={10.2478/v10178-011-0053-9}, keywords={power quality, real time, multiharmonic least-squares fitting}, }
