Abstract
The transmission system is designed to be protected by 40 kA rate of circuit breaker fer 345 tV system and 31.5 kA and 50 kA rate of circuit breaker for 154 kV system. The short circuit current shows the tendency of exceeding circuit breaker duty for some substations and the tendency will continue if an appropriate countermeasure will not be applied to. In order to solve this problem from the viewpoint of system operation, the 154 kV system is under reconfiguration to be radial systems. This paper presents application effect of resistive and inductive SCFL (Superconducting Fault Current Limiter to Korea power systems. An algorithm of SCFL site decision is suggested.
