Improvement of distance protection algorithms based on phasor measurements [PDF]

open access: yesE3S Web of Conferences, 2023
Distance protection of overhead lines is widely used and is continually being improved. However, the distance protection cannot work stably and is blocked in several electromechanical transients. Additionally, a non-linear arc can affect the stability of
