Commutation failure caused by AC system failure is most common phenomenon of AC/DC dynamic interaction. The research about the DC commutation failure simply caused by AC system failure at a certain moment may not accurately reflect the complexity of HVDC commutation failure. This paper points out that the commutation voltage amplitude and phase angle and the closing time of fault are the main factors...
