An Adaptive Reclosing Scheme Based on Phase Characteristics for MMC-HVDC Systems [PDF]
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.

Uninterrupted power supply to BESS based microgrid system using adaptive reclosing approach
As more than 80% of faults on overhead lines are temporary (transient) in nature which is caused due to lightning strikes, momentary bird or tree limb contact, wind bringing conductors in contact, etc.

An adaptive reclosing strategy for MMC-HVDC systems with hybrid DC circuit breakers [PDF]
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)

This study presents an adaptive single‐phase reclosing method based on voltage harmonic measurement implemented in a digital harmonic filter. This filter and the transmission system were modelled in a real‐time digital simulator. A distance relay was used for protection and reclosing, responding as if it was in field operation.
