고장전류 저감을 위한 초전도 한류기 Bus-Tie 적용에 관한 검토

Applying Superconduction Fault Current Limiter in the Bus-Tie Location

As the power system is more complex and power demands increase, the fault currents have the tendency of increasing gradually. In the near future it will happen that the fault currents exceed circuit breaker rating for some substations. In this paper, the resistive SFCL (Superconducting Fault Current Limiter) is installed at Bus-Tie location to reduce the fault current in korea power systems and evaluated technical and economical Impacts.
