(orcid)0000-0001-6095-3776 A robust measurement method for supraharmonics under power frequency deviations 2019 Access copy available to the general public Unrestricted This paper introduces a new measurement method for supraharmonic distortion with improved robustness against power frequency deviations. The proposed method is based on wavelet analysis and it is designed to analyze a 10 cycles measurement interval. Fourier-based methods, instead, must analyze a fixed 200 ms window in order to avoid apparent shifts of the supraharmonic frequency components. The results of the experimental measurements presented in the paper show that the Fourier-based method suggested in IEC 61000-4-7 standard produces results affected by the value of the power frequency. The proposed method, instead, provides results completely independent of the power frequency. This feature also removes the need of a previous high pass filtering stage, required for the IEC method. Moreover, the proposed method has the additional advantage of working on the same measurement interval as traditional harmonics (below 2 kHz), feature that can reduce the complexity of measurement instruments. info:eu-repo/grantAgreement/EC/H2020/676042/EU/Metrology Excellence Academic Network for Smart Grids/MEAN4SG This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 676042-MEAN4SG info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Khokhlov, V.
