Commutation Failure Prediction in LCC-HVDC under Severe Voltage Distortion
In modern power systems, Line Commutated Converter (LCC)-HVDC technology remains a cost-competitive solution for high-capacity transmission, yet it is inherently susceptible to commutation failure (CF) during AC grid disturbances. Traditional CF prediction methods, such as the Commutation Failure Prevention Control (CFPREV) and the Critical Commutating
