Mitigating commutation failures in HVDC systems with SFCL deployment

International Journal of Electrical Power & Energy Systems, 2023
Commutation failures represent a prevalent issue encountered in line-commutated-converter high voltage direct current (LCC-HVDC) systems. As the widespread deployment of HVDC systems continues, the risk associated with commutation failures increases, posing a growing threat to power grids due to their potential to trigger severe consequences, including
