Abstract

When faults occur in a distribution network, blackout loads must be restored as fast as possible to minimize interruption of electric service. This paper presents an expert system to restore distribution networks. The system is designed to minimize switching operations in a heuristic sense by using heuristic rules. The restoration process is converted to the feasible path finding problem in the state space of expert system by application of general topological knowledge base. Multiple load transfer algorithm is proposed to deal with complex situations.

배전계통에서의 사고 발생시 정전으로 인한 수용가의 손실을 최소로 하기 위하여 정전구역에 대한 신속한 복구가 이루어져야 한다. 본 논문에서는 배전계통의 정전복구를 위한 전문가 시스템을 제안하였다. 제안된 전문가 시스템은 복구과정에서 전문가의 경험적 규칙을 이용함으로써 복구에 소요되는 스위칭 횟수를 최소화 하도록 하였다. 복구 과정은 일반적인 위상구조 지식 기반의 응용을 통해 전문가 시스템의 상태공간에서 타당한 경로를 찾는 문제로 표현하였다. 또한, 다양한 배전계통 구조를 고려하기 위해 다중 부하절체 기법을 제안하였다.
