Abstract
도시가스 배관망의 안전관리 및 위험예측은 매우 중요한 문제로 인식되고 있으며 가스 누출지점을 실시간으로 감지함으로써 안전사고 예방을 위한 노력은 필수적이다. 따라서, 본 연구에서는 가스누출 시, 압력변화에 따른 상관관계(correlation)를 통해 실시간 누출지점감지를 목적으로 연구를 진행하였다. 본 연구에서는 총 378 m의 배관에 5개의 누출밸브를 설치하여 실험하였고, 시뮬레이터를 통해 누출지점을 감지함으로서 실제 누출지점과 비교해 보았다. 실험결과, 실험을 통한 누출지점과 실제 누출지점은 6 m 내의 차이를 보였으며 향후, 본 기술의 적용이 필요한 위험구역에서의 실증을 통한 상용화가 수반되어야 할 것이다. Gas pipeline safety management and risk prediction are recognized as a very important issue. And the effort to prevent accidents is essential. So, in this study, it was studied through correlation of pressure changes for leak point detection in real-time. It experimented by installing the five leakage valves in the pipe of 378 m and compared the actual leak points with simulation results. The results showed that experimental leak points and the actual leak points have differences within the 6 m. And this technology has to be commercialized by the demonstration in dangerous zone.
