New Adaptive Reclosing Technique in Unbalanced Distribution System [PDF]
Energies, 2017 The conventional reclosing of a distribution system is performed after a fixed dead time. However, it may lead to the increased outage time due to delayed reclosing. To solve this problem, this paper proposes a new adaptive reclosing scheme.

An adaptive reclosing scheme for flexible DC grid based on residual voltage S-transformation [PDF]
Scientific ReportsWhen a fault occurs on a line, it is necessary to quickly isolate the fault to improve the safety and reliability of the transmission system. Due to the lack of effective ability to identify the nature of faults, the traditional automatic reclosing ...

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

An Adaptive Reclosing Strategy for MMC-HVDC Systems With Hybrid DC Circuit Breakers [PDF]
IEEE Transactions on Power Delivery, 2020 Modular multilevel converter (MMC) based high voltage direct current transmission (HVDC) is an effective solution for large-scale renewable power integration over long-distance. In the overhead MMC-HVDC systems, the high voltage DC circuit breakers (DCCB) are implemented to interrupt the DC fault current.

An Adaptive Reclosing Scheme Based on Phase Characteristics for MMC-HVDC Systems [PDF]
IEEE Transactions on Power Delivery, 2022 To improve the reliability of power supply, reclosing schemes are required after transient faults, which commonly occur in overhead line based high voltage DC (HVDC) systems. However, in the event of permanent faults, the auto-reclosing scheme may cause a severe strike.
