Abstract :
In this paper, the application of four algorithms based on least square sine fitting methods for power quality measurements is discussed. It is shown how these algorithms can be used to extract power quality disturbances (such as transients or waveform distortions) from the voltage signal. Also, the application of these algorithms for estimation of the total harmonic distortion is discussed and the results are compared with the ones obtained according to the IEC 61000-4-7 standard.
