Using super conductive fault current limiter to retrieve the protection coordination of networks in the presence of distributed generation

Distributed Generation Resources are increasingly used in distribution systems due to their great benefits. The application of DG, however, can cause different problems such as miss-coordination, false tripping, blinding and reduction of reach of protective devices. Using superconducting fault current limiters (SFCLs) is one of the best methods to minimize these problems comparing to the other conventional methods. In this paper coordination problem of overcurrent relays in the presence of distributed generation resources. The presented method is implemented on IEEE 30 buses network and the efficiency of the proposed approach is tested and proved.
