Abstract :
This paper presents an application of single DC reactor type fault current limiter (FCL) with a gate turnoff (GTO) thyristor bridge as an emergency power source. A DC reactor type FCL stores electrical energy in a superconducting coil at a steady state. When a power transmission stops due to line faults, the FCL supplies stored energy to the load. This conception can be realized by operating the GTO thyristor bridge as an inverter. On the other hand, the function of fault current limitation is possible by keeping all GTO thyristors turned-on. The proposed FCL is numerically tested in a three-phase distribution system
