Criterion of single-phase fault nature of AC line considering the influence of commutation failure

Criterion of single-phase fault nature of AC line considering the influence of commutation failure

The amplitude of AC line current at the inverter side is affected by DC commutation failure and fluctuates for a short time after single-phase trip.The fluctuation range increases with the increase of the number of DC commutation failures,resulting in the misjudgment of the traditional single-phase...
