Improved digital algorithm for adaptive reclosing for transmission lines with shunt reactors

IET Generation, Transmission & Distribution, 2016
This study presents an improved algorithm of adaptive single‐phase auto‐reclosing (ASPAR) for extra high voltage transmission lines with shunt reactors. It shows that the odd and even harmonic factors of the faulted phase voltage have different characteristic in different stages after breaker open.

Non-Fault Detection Scheme Before Reclosing Using Parameter Identification for an Active Distribution Network

Energies
The distribution network line has the risk of an unsuccessful three-phase blind reclosing in permanent fault. Based on the response of the inverter of the distributed generation (DG) to the short-term low-frequency voltage disturbance to the line to be ...

Adaptive Single Phase Auto-Reclosing Using Voltage Magnitude Pattern

, 2020
This paper presents a novel adaptive single phase auto-reclosing (ASPAR) scheme based on the first derivation of local voltage magnitude (VM) of the faulted phase for determination of dead time of transient faults. The algorithm is fast and uses low-frequency sampling and adaptive threshold value (ATV).

An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines

Alexandria Engineering Journal
As a large percentage of faults in transmission lines are single-line-to-ground (SLG) and transient in nature, the use of adaptive single-phase auto-reclosing (ASPAR) schemes is essential.

Quasi-single phase permanent fault identification method and reclosing strategy based on multi-level confidence rules

International Journal of Electrical Power & Energy Systems
As global temperatures rise, the frequency of lightning increases, making lightning one of the principal threats to power-system security. Field incidents indicate that, within the automatic reclosing time window, multiple-stroke lightning can exhibit ...
