Line-Start Permanent Magnet Synchronous Motor Supplied with Voltage Containing Negative-Sequence Subharmonics

open access: yesEnergies, 2023
In some power systems, the voltage waveform contains frequency components less than fundamental, called subharmonics or subsynchronous interharmonics. Voltage subharmonics can be both positive- and negative-sequence, independent of their frequency (order)

An Order-Reduction Method of Interharmonic Analysis Model Based on the Principle of Interharmonic Interaction

open access: yesCPSS Transactions on Power Electronics and Applications, 2021
This paper presents a method on order-reduction of interharmonic analysis based on the principle of interharmonic interaction. First, we obtain the transformation between dynamic phasors in dq coordinate and dynamic phasor sequence components (DPSCs).

A Review of Total Harmonic Distortion Factors for the Measurement of Harmonic and Interharmonic Pollution in Modern Power Systems

open access: yesEnergies, 2021
Harmonic distortion is one of the disturbances that most affects the quality of the electrical system. The widespread use of power electronic systems, especially power converters, has increased harmonic and interharmonic emission in a wide range of ...

Effects of Negative Sequence Voltage Subharmonics on Cage Induction Motors

open access: yesEnergies, 2022
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.
