분산전원을 고려한 배전계통의 개선된 보호협조 방안 연구

Recently, There has been growing interest in Distributed Generations with high-energy efficiency due to the increasing energy consumption and environmental pollution problems. but an insertion of Distributed Generations to existng power distribution system can cause several problems such as voltage variations, harmonics, protective coordination, increasing fault current etc, because of reverse power. This paper was applied to Sukumar M[1] proposal schemes and identily the faulted section performing short-circuit analysis by MATLAB program to distribution systems interconnected a large number of distributed generations.
