Dynamic Phasor Modelling of LCC-HVDC System Based on a Practical Project [PDF]

open access: yesE3S Web of Conferences, 2021
This paper presents a detailed dynamic phasor modeling process of a line-commutated converter-based HVDC (LCC-HVDC) system. Firstly, the dynamic phasor models of the single-ended LCC rectifier station, inverter station and the DC line are established ...

Two modified DFT‐based algorithms for fundamental phasor estimation

open access: yesIET Generation, Transmission & Distribution, 2022
The discrete Fourier transform (DFT) is a powerful phasor estimation algorithm conventionally used in digital relaying applications. The DFT‐based phasor estimation is usually accompanied by oscillatory error due to the presence of the decaying DC (DDC ...

Discontinuities in the Electromagnetic Fields of Vortex Beams in the Complex Source/Sink Model [PDF]

open access: yes, 2017
An analytical discontinuity is reported in what was thought to be the discontinuity-free exact nonparaxial vortex beam phasor obtained within the complex source/sink model.

Resolution of 4 components in the same pixel in FLIM images using the phasor approach

open access: yesMethods and Applications in Fluorescence, 2020
In several cellular systems, the phasor FLIM approach has shown the existence of more than 2 components in the same pixel, a typical example being free and bound NADH.
