A Comprehensive Review of Various Fault Location Methods for Transmission ‎Lines Compensated by FACTS devices and Series Capacitors [PDF]

open access: yesJournal of Operation and Automation in Power Engineering, 2021
Fault location in transmission lines compensated by flexible alternating current transmission system (FACTS) devices and series capacitor (SC) compensators is much more complicated than simple lines due to the presence of time-variant voltage and current

A novel superimposed component‐based protection method for multi‐terminal transmission lines using phaselet transform

open access: yesIET Generation, Transmission & Distribution, 2023
This paper presents a novel protection method for transmission lines that estimates the superimposed component phasor using phaselet transform. The phaselet transform computes the phasors over variable‐lenfgth data window at the instant of a fault, so it
