Application of fault current limiter to looped distribution network

Distribution network will change its characteristics from conventional power distribution to power exchange between distributed power generations and loads. In the future distribution network will be operated in loop configuration instead of present radial shape for getting higher availability and higher efficiency. Problems in such distribution network are increase of short circuit current and voltage sag. These problems will be solved by application of fault current limiter. This paper proposes application of fault current limiter and shows performance obtained by computer simulation.
