모델링과 검증에 의한 파이프 라인 시스템의 유출 탐지
Leakage Detection of Pipeline System Based on Modeling and Identification
파이프 라인에서의 유출을 진단하기 위하여 모델에 기초한 방법을 개발하였다. 파이프 라인에서 액체가 이송되는 경우에 대한 일반적인 모델에 기초하여 유출이 발생하는 경우 이를 판단하고, 그 위치를 찾아내는 방법을 구성하였다. 길이 97.6m, 내경 3/8"의 파이프 라인에서 물을 이송하여 실험을 수행한 결과, 약 3%이상의 유출이 발생할 경우 유출 여부를 감지할 수 있었으며 유출량에 따라 최대 3% 이내의 정밀도로 유출 위치를 진단해 낼 수 있었다.
A leakage detection method based on a physical model of a pipeline system is proposed. Based on fundamental balance equations for liquid transporation in a pipeline, the method was constructed to diag-nose the leak point as well as to detect the leakage. The proposed method was evaluated in a water transpor-ting pipeline system of which the length is 97.6m and inner diameter is 3/8", respectively. As a result, the method could discriminate the leakage whenever the leaking rate is more than 3% of the total flowrate and localize the leaking point within 3% of accuracy depend on the leaking rate.
