要約(英語): In this paper, we describe the control of electronic frequency converters (EFCs), which enables them to continue independent operation in the event of a fault, which is necessary to replace all the frequency conversion facilities in the Tokaido Shinkansen to EFCs. To continue independent operation of the EFCs under faults, we have developed a new overcurrent suppression control scheme applied to the three-phase AC input and output EFCs. We confirm through simulations that the new control suppresses fault current effectively and enables the EFCs to continue operation through a series of operations in which short-circuit faults occur at the feeding circuit, and the circuit breaker interrupts the circuit at the location of the fault following its occurrence and re-closes it after a short interval.
