Power system lines are not only used for electric energy transfer, but also for the transmission of a communication signal, called the mains communication voltage. The mains communication voltage is in the form of a telegram code, superimposed on the

One of the types of power quality disturbances met in a power system is voltage fluctuations. Cyclic voltage fluctuations are interconnected with the presence of subharmonics and interharmonics – that is components of frequency less than the fundam

Various power quality disturbances commonly occur in a power system, including voltage fluctuations. These can be analysed as simultaneous occurrences of voltage subharmonics and interharmonics of various frequencies – components of frequency less

Cyclic voltage fluctuations can be considered as a superposition of the fundamental voltage component, subharmonic and interharmonic components – that is the components of frequency less than the fundamental one or not being its integer multiple. A

The adjacent interharmonic pairs or single adjacent interhamonic symmetrical to the fundamental/harmonic component can be caused by the large-scale grid connection of renewable energy. It is usually necessary to confirm the type of adjacent interharm

The effects of harmonics, interharmonics, and subharmonics on low-voltage distribution networks, leading to a deterioration in electrical power quality, have become more evident in recent years. The main harmonic sources are power electronic devices

In this paper, a new accurate and comprehensive analytical model of harmonic and interharmonic distortion produced by a single-phase AC/DC diode bridge rectifier (DBR) is presented. Its main and new characteristic is the ability to consider the prese

Interharmonics of high frequency will cause voltage’s peak value fluctuation, which will result in flicker of fluorescent lamp and LED lamp. To realize accurate evaluation of the flicker, a method based on multiresolution S-transform is proposed to
