A review of single phase adaptive auto-reclosing schemes for EHV transmission lines

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 damage to the system. Thus, adaptive single-phase auto-reclosing (ASPAR) based on investigating existing electrical signals has fascinated engineers and researchers. An ASPAR blocks CB reclosing onto permanent faults and allows reclosing permission once secondary arc is quenched. To address the subject, there have been many ASPARs techniques proposed based on the features trapped in a faulty phase. This paper presents a critical survey of adaptive auto-reclosing schemes that have hitherto been applied to EHV transmission lines.

A Comprehensive Review of Auto-Reclosing Schemes in AC, DC, and Hybrid (AC/DC) Transmission Lines

“…Each scheme is further categorized into two subschemes based on research analysis, as shown in Fig. 4 [35].…”

Intelligent fault analysis of transmission line using phasor measurement unit incorporating auto-reclosure protection scheme

“…Auto-reclosing is the sequence of opening and reclosing the circuit breaker followed by a resetting of a high volt alternating circuit [17]. Most of the overhead transmission line faults of around 80-90% are temporary in nature [18], and they stay for a very small duration of time.…”

Identification between internal and external faults of UHVDC transmission lines based on sequential overlapping derivative transform of voltage transient

“…The key to the protection of the DC line is the accurate and reliable identification of transmission lines faults. The fast‐responding DC line protection has become an important guarantee for the safe operation of UHVDC transmission lines [11–14].…”
