Abstract :
Mathematical models for the studied power distribution system and its superconducting fault current limiter (SFCL) are given. Based on these models and EMTP, the influence on the peak value of short circuit current, the non-fault line voltage of feeder, and the voltage over SFCL due to the limiting resistance of SFCL and the fault detection time is analyzed. The results show that SFCL can drastically limit the peak value of fault current, and it is helpful when switch faults occur. In addition, SFCL is in favor of maintaining the transient non-fault line voltage and increases the power quality.
