초록

본 논문은 전력설비 피해 감소를 위한 배전시스템의 지능형 재폐로방식을 제안하였다. 재폐로 시도횟수를 늘릴수록 공급신뢰도는 향상될 수 있지만, 전력설비에는 사고전류에 의한 충격이 누적된다. 제안된 방식은 사고전류의 크기에 따라 재폐로 시도횟수와 무전압시간을 결정하여 배전시스템 공급신뢰도를 유지하면서 전력설비의 피해를 감소시킬 수 있다. 사례연구에서는 현장 운전 데이터를 사용하여 제안된 지능형 재폐로방식에 대한 효율성을 입증하였다.

This paper presents an intelligent reclosing scheme to reduce a damage of power equipments in power distribution systems. As the number of reclosing shot increases, an power supply reliability is improved, but an impact of electric facilities by fault currents is accumulated. The proposed scheme determines the number of reclosing shots and its intervals according to ilie magnitude of fault current. Therefore, this scherre reduces a harm of electric facilities and muntains the power supply reliability. Case studies is performd to verify the effectiveness of the proposed scheme using field operation data.
