  • Alarm system is very important for the safety of nuclear power plant. When alarm, operator refers alarm logic diagrams to identify the logical relationship between the alarm and its causes. This paper propose a system which tracks the logical path between alarm and its causes on the alarm logic diagrams of Wolsung nuclear power plant unit 3 & 4. And a grammar for the validation of logic diagrams expressed in 2 dimensional strings, and logical operations with 3 states to track alarm-cause paths and to display the state of logics are proposed. This system is on operation at Wolsung site.

  • 원자력 발전소 운전시 이상 현상으로 인한 발전소의 정지 등 기타 여러 사고시 그 원인을 신속히 파악하여 조치하는 잎은 발전소의 안전과 효율적인 측면에서 매우 중요한 부분이다. 경보원인추적시스템(ACTS: Alarm-Cause Tracking System)은 발전소 현장에서 자주 사용하는 경보 논리도면을 자동화하여, 경보의 원인을 보다 상세하게 추적하여 경보절차서에 표시되는 원인들 중 실제로 발생한 원인과 그에 해당하는 절차 부분을 강조하여 표시함으로써 운전원이 쉽게 상세원인을 파악할 수 있도록 한다. 또한 이 시스템은 운전원이 경보의 발생경로와 논리상태를 그래픽으로 전산화된 논리도면상에서 확인하여 경보에 대한 빠른 조치를 취할 수 있도록 인터페이스를 제공한다.

  • When a alarm is happened in nuclear power plant, operator tries to identify the direct and specific causes of the alarm and to do proper actions to mitigate the effect of it. To recognize the specific causes of it, the operator uses his experiences, alarm procedures, logic diagrams and so on. But, if the alarm procedure described many causes of the alarm unfortunately, it is very difficult for the operator who has no experience on the alarm to search the causes of it in hundreds of logic diagrams when emergency. In this study, a system is proposed, which tracks and displays the causes of alarms on-line from computerized logic diagrams.
