Abstract

보일러 플랜트의 운전관리 미숙(오조작, 오판단)으로 인해 발생하는 shutdown을 예방하기 위한 운전 지원용 전문가 시스템을 개발하였다. 본 연구에서는 대상공정과 거동에 대한 symbolic modeling을 실시하고, 조작에 의한 공정상태 변화의 모사방법과 상황 의존적인 문제를 해결하는 방법을 제안하였다. 또한, 위험상황과 운전상황의 인식에 필요한 지식을 일반화하여, 오판단과 오조작으로 인한 보일러의 이상상태를 조작에 미리 앞서서 예측할 수 있는 방법을 제시하였다. 개발된 시스템을 실제 공정에 적용하여 제시한 방법이 유용한 것임을 검증하였다.

An operation aiding expert system is developed for preventing an unexpected shutdown caused by operation errors or misjudgements in boiler plants. Based on symbolic model about the plant structure and the behavior characteristics, the change of process states is simulated. And the method for solving context-dependent problem is suggested. With generalized knowledges for the recognition of operational situations and hazardous conditions, a strategy is suggested for anticipating accidents caused by operation errors or misjudgements in advance. By the results of the application of this system to the real plant, it is shown that the methodology suggested in this study is useful.
