Exponential Smoothing of Multiple Reference Frame Components With GPUs for Real-Time Detection of Time-Varying Harmonics and Interharmonics of EAF Currents

, 2018
In this research work, a multiple synchronous reference frame (MSRF)-based analysis method, used together with exponential smoothing (ES) to accurately obtain the time-varying harmonics and interharmonics of electric arc furnace (EAF) currents, is ...

Induction Motor Under Unbalanced Voltage Subharmonics

IEEE Access
In addition to fundamental harmonics, the voltage waveform may contain various undesirable components, including subharmonics (subsynchronous interharmonics) and interharmonics (SaIs), which are components with frequencies less than or not an integer ...

METHODS OF SPECTRAL ANALYSIS OF RANDOM PROCESS FLUCTUATIONS OF VOLTAGE AND CURRENT FEEDER TRACTION SUBSTATION DC

Nauka ta progres transportu, 2010
The methods for determination of spectral composition of random functions of voltage and current of traction substation feeder are proposed. The low frequency components of their spectra (interharmonics) are obtained.

Influence of subharmonics and interharmonics voltage on curents in windings of an induction machine

, 2011
In power systems commonly appear various disturbances such as voltage unbalance, voltage deviations, frequency deviations (in autonomous power systems) and voltage waveform distortions. Voltage waveform distortions are usually associated with presence of

Time domain aggregation of interharmonics from parallel operation of multiple sources

A model to analyze the probability distribution of the peak value of the interharmonics aggregating at the point of common connection is developed. With multiple sources of interharmonics, the fluctuations in the peak value of voltage or current matters.
