High voltage inverter commutation
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.

FAQS about High voltage inverter commutation
Are commutation failures a threat to high-voltage direct current inverters?
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.
Do inverter commutation failures cause transient voltage fluctuations?
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.
What is commutation failure in LCC-HVDC?
Introduction Line-commutated converter-based high voltage direct current (LCC-HVDC) technology has been widely used because of advantages such as lower transmission losses and bulk power transmission . However, commutation failure is one of the most common inverter failures in the LCC-HVDC systems.
Can a commutation failure cause severe sending end voltage fluctuations?
Simulation results demonstrate the correct analysis and effective suppression method. Inverter commutation failures (CFs) in LCC-HVDC systems can cause severe sending-end voltage fluctuations.
What is line-commutated converter-based high-voltage direct current (LCC-HVDC)?
1. Introduction With the advantages of low power loss, large transmission capacity and flexible power regulation, line-commutated converter-based high-voltage direct current (LCC-HVDC) transmission systems have been widely used in cross-regional power transmission and renewable energy integration [, , ].
What are capacitor commutated converters?
Capacitor-commutated converters can make the commutation progress easier and faster with the help of capacitors in block A . However, the capacitors result in additional reactive power consumption, harmonics and overvoltage issues that should be eliminated by additional filters and lightning arresters .
