A Study on the Advanced Protective Coordination Schemes of 22.9[kV] Distribution System Interconnected New Renewable Energy System

신재생에너지 시스템이 연계된 22.9[kV] 배전계통의 개선된 보호협조 방안 연구

Recently, There has been growing interest in new renewable energy systems with high-energy efficiency due to the increasing energy consumption and environmental pollution problems, but an insertion of new renewable energy systems to existing power distribution systems 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, Brahma, A. Girgis[1] proposal schemes and identilys the faulted section performing short-circuit analysis by MATLAB programs to 22.9[kV] distribution system interconnected a large number of new renewable energy system and was analyzed on protective coordination between reclose and Sectionalizer.
