Abstract

Due to the Four Major Rivers Restoration Project, Nakdong River Estuary Barrage's designed flood quantity has been largely increased, and this has caused to construct several drainage gates at the right side of Eulsukdo island to secure the safety of downstream river area. For successful functioning of Nakdong River Estuary Barrage, such as flood control, disaster prevention, and the securing of sufficient water capacity, drainage gates at the both sides of island have to operate systematically and reliably. To manage this under restricted personnel and resources, we have implemented the IOS (Integrated Operation System) by integrating previous facilities and resources via information and communication technologies. The IOS has been designed to have higher availability and fault tolerance to function continuously even with the partial system's failure under the emergency situation like flood. Operators can use the system easily and acknowledge alarms of facilities through its IWS (Integrated Warning System) earlier. Preparing for Integrated Water Resources Management and Smart Water Grid, the architecture of IOS conformed to open system standards which will be helpful to link with the other systems easily.

낙동강 하굿둑에서는 4대강 사업으로 인한 낙동강 본류의 환경 변화로 설계홍수량이 크게 늘어남에 따라 낙동강 하류의 치수안전을 확보하기 위해 을숙도 우안에 배수문을 증설하게 되었다. 하굿둑에서의 수량 확보, 홍수조절, 재해예방 등의 기능이 원활하게 수행되기 위해서는 좌안의 기존 배수문과 우안의 신설 배수문이 유기적이고 안정적으로 운영되어야 한다. 한정된 인력과 자원 하에서 이를 운영하기 위하여 기존의 수자원시설과 정보통신기술을 융합한 통합운영시스템이 구축되었다. 통합운영시스템은 홍수 등의 위급한 상황에서도 부분적 결함에 의해 전체 시스템의 동작이 중단되지 않도록 높은 가용성과 결함 감내성을 지니도록 설계되었다. 운영과 유지관리에서의 편의성이 고려되었으며, 경보시스템을 구축하여 설비의 이상을 조기에 감지할 수 있게 하였다. 통합운영시스템의 아키텍처는 향후 유역통합운영과 스마트 워터그리드에 대비하여 시스템간의 연계가 용이한 개방형 표준을 지향하였다.
