Study of Fault Current Limiter Applied to Loop Distribution Network

摘要

As discussed in the field of Smart Grid distribution network will change its characteristics from conventional power distribution to power exchange between distributed power generations and loads. The 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 reported by authors. This paper reportslimitation of fault current limiter application and shows protection coordination with impedance relaythrough computer simulation.
