Abstract	This paper deals with the commutation failures of HVCD system. Commutation failures are caused by AC voltage distrotions at inverter side and cause the HVDC system oscillations. In this paper, in order to know a correct incidence and onset of the failures, theoretical analysis, the simulation and the investigation at actual system are carried out and the dynamic performace simulations are performed by PSCAD/EMTDC. Finally, the condition that the failure could be generated and how to reduce the failures are analyzed.
