Suppression to concurrent commutation failure of UHVDC with hierarchical connection mode based on improved dc current prediction

Abstract For the ultra high‐voltage dc (UHVDC) transmission with hierarchical connection mode (HCM) at the inverter side, local commutation failure (LCF) at one layer after the ac fault may cause concurrent commutation failure (CCF) at the non‐fault layer. The inter‐layer couplings at the ac and dc...
