The Operating Method of Superconducting Fault Current Limiter for Total Superconducting Power System

초전도전류제한기의 초전도 전력시스템에서의 운전방안

Design & operation of power system for meeting increase of electric power demands is becoming more difficult and complex. One of reasons is increase of fault current. As one of the most effective methods for suppressing the fault currents, installation of SFCL are expected. An image of future hybrid & total SC power system which have introduced SC generator cable transformer, fault current limiter, SMES & shunt reactor, etc. are presented. In the SC power system, it is pointed that a SFCL should play an, important part of quenching current level coordination to prevent the other SC devices from quench.
