Adaptive Single-Pole Auto-Reclosing Scheme Based on Secondary Arc Voltage Harmonic Signatures [PDF]
Energies, 2021 This paper presents an advanced adaptive single-pole auto-reclosing (ASPAR) scheme based on harmonic characteristics of the secondary arc voltage. For analysis of the harmonics, short-time Fourier transform (STFT), which is a universal signal processing ...

Adaptive single-phase auto-reclosing method using power line carrier signals [PDF]
International Journal of Electrical Power and Energy Systems, 2018 Abstract This paper proposes a new method for adaptive single-phase auto-reclosing (ASPAR) that improves the rate of successful reclosing actions after the occurrence of a transient single-phase fault and prevents unsuccessful reclosing. After the occurrence of a fault, the only faulty phase is disconnected by the protection system (e.g., distance ...

An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines [PDF]
Alexandria Engineering JournalAs 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.

Comparison between traditional single‐phase auto reclosing and adaptive technique based on harmonic content measurement [PDF]
IET Generation, Transmission and Distribution, 2017 This study presents the results of single‐phase auto reclosing technique tests, comparing the performance of traditional procedure and fast adaptive procedure. The last is based on the measurement of voltage harmonic content on the transmission line faulty phase terminals.

A Current-Commutation DC Circuit Breaker with Adaptive Reclosing Capability [PDF]
E3S Web of Conferences, 2021 DC faults are critical events in a flexible high-voltage dc (HVDC) grid. Thus, ensuring that the power system returns to normal operation rapidly and reliably after fault isolation is very important. This requires a HVDC breaker. In overhead line systems

A review of single phase adaptive auto-reclosing schemes for EHV transmission lines [PDF]
Protection and Control of Modern Power Systems, 2019 Abstract Statistics shows that transients produced by lightning or momentary links with external objects, have produced more than 80% of faults in overhead lines. Reclosing of circuit breaker (CB) after a pre-defined dead time is very common however reclosing onto permanent faults may damage the power system stability and aggravate severe

New approach to adaptive single pole auto-reclosing of power transmission lines
IET Generation, Transmission and Distribution, 2010 In this study, a novel digital algorithm is introduced for recognition of arcing (transient) faults and determination of dead time for adaptive auto-reclosing. The algorithm distinguishes between arcing and permanent faults by using the zero sequence voltage measured at the relaying point.

International Journal of Electrical Power and Energy Systems, 2019 Abstract This paper presents an adaptive auto reclosing scheme (AARS), applicable to active distribution systems, which are equipped with Phasor Measurement Units (PMUs). The scheme differentiates between temporary and permanent faults by taking into account the operational conditions of the network when determining the reclosing dead time.
