In order to reduce the harm of voltage fluctuation and flicker, effective measurement is necessary for providing accurate pa-rameters needed in evaluation and compensation. An evaluating method based on Hilbert transform and Chirp-Z transform is proposed. The method is simulated by Matlab software and verified by the measured data. The results of simulation and verification show that the precision of this method is in line with IEC standards.
