Abstract

This paper presents active management of feeder automation systems using active database. DAS(Distribution Automation System) has been managed for feeder automation in passive manner. Therefore, feeder automation system has to be managed by operator when feeder overloadings is detected. It may be possible for propagating the feeder overloadings area by operator's mistake. To overcome this defect, the author proposed the feeder automation technique with active manner to obtain feasible feeder reconfiguration. Active database can manage feeder automation system by data driven monitoring of events and by corresponding actions without operator's intervening. To manage feeder automation system with active manner, production rule, active rule manager are designed. And active database system architecture for feeder automation system is proposed. Test results on the KEPCO's 108 bus distribution system show that the performance is efficient and robust.

본 연구에서는 능동 데이터베이스를 이용하여 배전선로의 운전을 자동화하는 방안을 제시하였다. 기존의 선로운 전자동화 시스템에서는 수동형 데이터베이스를 사용으로 인위에 의한 실수로 광역정전 또는 과부하 구간의 파급등이 발생될 우려가 있었다. 그러나 제시된 능동 데이터베이스는 선로운전 자동화 시스템 데이터베이스의 상태를 항상 감시하고 스위치의 상태나 계통의 전류 또는 부하량이 변경되었을 경우 그에 상응하는 일련의 작업을 사용자의 개입없이 능동 규칙이용하여 데이터베이스 스스로 수행하도록 함으로써 인위에의한 실수를 최소화 할 수 있다. 제시된 방식을 실 계통인 서울의 K지점의 모의 배전계통에 적용하여 그 유용성을 입증하였다.
