Commutation Failure Mitigation in LCC-HVDC Systems Through Improvement of VDCOL Characteristic
2025 IEEE 7th International Conference on Energy, Power and Grid (ICEPG)Commutation failure (CF) is a common issue encountered on the inverter side of line-commutated converter high voltage dc (LCC-HVDC) systems. The primary cause is a fault on the AC side of the inverter, which leads to the unexpected re-conduction of the ...
