“…To ensure that the FCL offers a large inductance during a fault, the MMF cancelation in each core should be such that (2) where is the length of the flux path around the core, is the number of turns in the ac winding, and is the peak value of the fault current at which the FCL is designed to operate.…”

The design principles and performance characteristics of a prototype high-temperature superconductor saturable magnetic core-type fault current limiter are described. These are based on a distribution network service provider feasibility specification that included the footprint and regulatory requirements for limiting fault currents. Time-domain simulations using PSCAD/EMTDC are given to illustrate specific applications and the transient behavior of the different distribution system configurations are investigated.

Abstract-Using fault current limiter (FCL) is an effective way to solve the problem that short circuit current exceeds the standard. How to quickly identify short circuit faults is one of the keys. Thus, this paper presented a fast identification method for short circuit fault based on the average curvature of current waveform. A simple fault current limiter system was built in PSCAD, and the method was studied. The results show that it is faster than using current instantaneous value or the current change rate as the criterion. In view of the situation that the average curvature may exceed when the load changes sharply. It was proposed that the average curvature and the current change rate could be used as the combination criterion, and the fault could be identified quickly and accurately too.

“…But the breakers have a large foot print; higher cost and no comprehensive test data is available in DC grid environment. Fault current limiting using superconducting fault current limiters [7,8], is another approach discussed in literature. But the limiter fault current varies with the condition of the AC grid and the location of the fault along the line [9].…”
