Adaptive CFPREV Control for Cascading Commutation Failure Mitigation Considering Reactive Power Interaction

IEEE Access
Advancing the firing angle implemented by the commutation failure prevention (CFPREV) is an effective method for commutation failure (CF), but the increase of reactive power consumption of local inverter would cause adverse influence on voltage at the ac
