Study on HVDC commutation failure and voltage compensated variable slope VDCOL control
2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018In this paper, through the analysis of HVDC commutation failure mechanism, the influence of commutation voltage reduction on commutation failure is studied. Based on this, a method which can restrain commutation failure and subsequent commutation failure and improve the recovery performance of the system is studied, that is voltage compensation slope ...

Commutation Failure Mitigation in LCC-HVDC Systems Through Improvement of VDCOL Characteristic
2025 IEEE 7th International Conference on Energy, Power and Grid (ICEPG)Commutation failure (CF) is a common issue encountered on the inverter side of line-commutated converter high voltage dc (LCC-HVDC) systems. The primary cause is a fault on the AC side of the inverter, which leads to the unexpected re-conduction of the ...

An adaptive fuzzy voltage dependent current order limiter (VDCOL) to enhance the performance of a multi-feed-in HVDC system is proposed in this paper. The adaptive fuzzy VDCOL exports an adaptive current order through fuzzy rules which need one point's voltage of HVDC transmission line and its derivative to time.
