Commutation failure is the most common disturbance in thyristor converters during inverter operation which can be triggered by different kinds of faults either the external faults (symmetrical or asymmetrical faults in the AC side, or the DC link to ground fault at the DC link side) [4] or by the internal faults such misfiring control or fault at the valves [5], the AC fault at sending end of the inverter can also leads to commutation failures.

With the increasing applications of high-voltage direct current inverters in heavy-load grids, commutation failures (CFs) pose a severe threat to the safe and stable operation of power systems. This study first sorts methods of CF inhibition into different categories and then investigates their effectiveness, adaptability and limitations.
Inverter commutation failures (CFs) in LCC-HVDC systems can cause severe sending-end voltage fluctuations. However, owing to the reliance of analysis methods on average-concept-based power quantities, the transient behavior of the sending-end voltage during inverter CFs remains elusive, hindering the advancement of its suppression strategy.
