Sources, Effects, and Modelling of Interharmonics [PDF]
Recently, the increasing use of power electronic systems and time‐variant nonlinear loads has brought number of power harmonics/interharmonics, and the power supply quality is therefore seriously threatened. The presence of interharmonics strongly poses more difficulties in modelling and measuring the distorted waveforms. Therefore, this paper reviews

Towards an EMC Coordination for Interharmonics in Public Low Voltage Networks
Flicker in LED lamps caused by interharmonic distortion was identified as a new interference mechanism, which is not yet covered by the existing EMC coordination. Following the process for EMC coordination, the article starts from a detailed characterisation of the new interference mechanism.

Effect of Interharmonics on Flicker of Fluorescent Lamps [PDF]
In order to analyze the inter-harmonic affections on the voltage flicker, the relationship between the inter-harmonics and flicker analysis are carried out. In order to be able to accurately determine the level of inter-harmonics to make the electric light flicker, inter-harmonic-flicker limit curve drawing method based on the voltage flicker ...

Effects of Negative Sequence Voltage Subharmonics on Cage Induction Motors
In some power systems, voltage waveforms contain, apart from harmonics, interharmonics and subharmonics that are components of frequency less than or not an integer multiple of the fundamental frequency.

This paper proposes an operating point fluctuations (OPF) framework to describe nonsinusoidal, nonstationary waveforms by modeling distortions as amplitude and phase fluctuations of a time‐varying fundamental component. Based on OPF, single‐phase and three‐phase power quantity expressions consistent with IEEE Std. 1459–2025 are derived under stationary
