Time discreteness of commutation failure in HVDC transmission
TENCON 2015 - 2015 IEEE Region 10 Conference, 2015Commutation failure caused by AC system failure is most common phenomenon of AC/DC dynamic interaction. The research about the DC commutation failure simply caused by AC system failure at a certain moment may not accurately reflect the complexity of HVDC commutation failure.

Research on fault diagnosis of HVDC commutation failure
2016 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2016Commutation failure is one of the common faults in HVDC system, which has an adverse impact on the safe operation of the entire power system. Fast and accurate diagnosis for commutation failure plays an important role in controlling the commutation failure.

Commutating failure simulation on a single-phase AC line-voltage-commutated inverter
[Proceedings] 1992 IEEE Workshop on Computers in Power Electronics, 2003A study of the commutating failure of a single-phase AC line-voltage-commutated inverter, is carried out with the help of a simulation method, combined with the steady-state operating diagram. A new aspect to explain this failure is presented. >

Electrical Engineering in Japan, 2009
AbstractThis paper proposes the safest novel commutation method for a matrix converter. There are two conventional commutation methods which depend on the polarity of the input line voltage (it is called “voltage commutation”) and depend on the polarity of the output current (it is called “current commutation”).

2009 IEEE International Symposium on Industrial Electronics, 2009
This work analyzes post-fault commutation failures and their effects in a thyristor based line commutated HVDC link. Simulation results of the example case available in PSCAD® reveal these failures. Two schemes have been suggested to mitigate these effects.

SVC Emergency Control Study on Continuous Commutation Failure
2019DC continuous commutation failure always a difficult issue that threaten the safe and stable of power grid. In order to increase the dynamic reactive power of the system, reduce the probability of continuous commutation failure. This paper focuses on the effect of SVC to reduce the failure of DC continuous commutation.
