HVDC converter simulation model with turn-off characteristics of series thyristors

International Journal of Electrical Power & Energy Systems
The converter models in common electromagnetic transient simulation software cannot reflect the dynamic turn-off process and the dispersity of series thyristors, which leads to inaccurate judgment and simulation of the commutation failure (CF).
