Published by A. Testa member IEEE, D. Gallo student member IEEE, R. Langella member IEEE Abstract: The harmonic and interharmonic analysis recommendations contained in the latest IEC standards on Power Quality are considered. The spectral leakage problems, due to synchronization errors of the analysed waveforms with the window widths adopted are analysed. Improvements of theContinue reading “On the Processing of Harmonics and Interharmonics: Using Hanning Window in Standard Framework”

Interharmonics: What They Are, Where They Come From and What They Do
Published by Michael B. Marz, American Transmission Company, Waukesha, WI Email: mmarz@atcllc.com INTRODUCTION The use of sophisticated power electronics and communication systems to improve power system efficiency, flexibility and reliability is increasing interharmonic distortion and adding equipment sensitive to that distortion to the system. Knowledge of interharmonics, their sources, effects, measurement, limits and mitigation, willContinue reading “Interharmonics: What They Are, Where They Come From and What They Do”

Defining Interharmonics
White Paper, April 2013 Contributed by Chris Mullins, VP of Engineering and Operations, Power Monitors, Inc. Email: cmullins@powermonitors.comWebsite: http://www.powermonitors.comTel: 800.296.4120 ABSTRACT Interharmonics are frequency components at noninteger harmonics of the line frequency. The proliferation of large DC-converter variable speed drives and wind/solar inverter generation has led to an increase in interharmonic levels. Troubleshooting the resultingContinue reading “Defining Interharmonics”

Power Quality – IEEE 519-2022
Published by Comsys AB, website: comsys.se, ADF Technology: Power quality – IEEE 519-2022 A commonly used and very important standard is IEEE 519-2022 (previous versions IEEE 519-1992 and IEEE 519-2014). The standard, among other things, puts two requirements on harmonics; and absolute maximum THDU level, and a variable maximum TDD level. All limits are appliedContinue reading “Power Quality – IEEE 519-2022”
