ABSTRACT:
In a superconducting energy storage apparatus including an AC-DC converter unit, a superconducting coil, a quench protection unit and a mechanical type persistent current switch, a self-firing type thyristor switch is connected in parallel to the mechanical type persistent current switch to be first operated in the event of an occurrence of trouble in an associated electric power system, and a control unit generates an ON instruction signal for turning on the persistent current switch so as to immediately establish a persistent current mode.
