Abstract

Commutation failure can be considered as the severest abnormal operation of thyristor HVDC converter. During the failure, power conversion from DC to AC is stopped until the AC voltage get recovered. The process of thyristor converter is subscribed at normal and abnormal state, respectively. The detection and the protection for Cheju HVDC are explained by computer simulation results.
