Detection of Flicker Caused by Interharmonics
IEEE Transactions on Instrumentation and Measurement, 2009International standard bodies have specified an instrument capable of detecting and assessing the severity of lighting flicker, which is called a flickermeter. However, a deficiency with regard to flicker caused by high-frequency interharmonics has been reported in the recent literature.

A Two-Stage ADALINE for Harmonics and Interharmonics Measurement
IEEE Transactions on Industrial Electronics, 2009Harmonics and interharmonics may introduce operational problems in electrical and electronic equipment. Therefore, monitoring harmonics/interharmonics for improving the power quality is of importance for both electric utilities and their customers. In this paper, a cascaded two-stage adaptive linear element (ADALINE) structure for both harmonics and ...

Operation and Control of a DVR in the Presence of Interharmonics
International Journal of Emerging Electric Power Systems, 2008 The paper discusses the operating principles and control characteristics of a dynamic voltage restorer (DVR). It is assumed that the source voltages contain interharmonic components in addition to fundamental components. The main aim of the DVR is to produce a set of clean balanced sinusoidal voltages across the load terminals irrespective of unbalance,

Interharmonics from a probabilistic perspective
IEEE Power Engineering Society General Meeting, 2005, 2005Some of the most remarkable issues related to interharmonics observed from a probabilistic perspective are presented. Attention is firstly devoted to interharmonic frequency and amplitude variability. Starting from the basic mathematical and computational aspects of probabilistic harmonic models, the difficulties to include interharmonics are discussed
