3. 결론

본 연구를 통해 개발된 원격 밸브 제어시스템의 특징은 크게 전력선 통신 기능과 소형 유압 파워 팩의 개발이라는 2 가지 측면에서 찾을 수 있다.

전력선 통신 기능은 기존 시스템에서 필수적인 신호선 포설 작업 및 신호선 포설 후 시스템 기능을 검사하기 위한 시운전 기간을 대폭 줄일 수 있다는 장점이 있다. 소형 유압 파워 팩의 경우 유압 장치를 밸브 액츄에이터 내부에 장착한 기능으로 기존 시스템에서 필수적인 파이프 설치 작업이 필요 없으며 이를 통해 시스템 설치 및 시운전 기간을 줄일 수 있다. 또한 별도의 파이프

설치 작업이 필요 없기 때문에 기존 시스템에서 발생되는 파이프 내부의 청소나 누유등에 의한 문제가 발생하지 않아 유지 보수 측면에서 많은 장점을 가진다. 본 원격 밸브 제어시스템은 위 두 가지 기능을 통해 시스템 설치 및 시운전 기간을 기존 시스템 대비 약 1/5 이하로 줄일 수 있다는 특징이 있다.
