Pipeline Leak Detection and Location Using Boundary Feedback Estimation: Case Study
Publication: Journal of Pipeline Systems Engineering and Practice
Volume 10, Issue 3
Abstract
This paper describes the development and testing of a methodology for continuous detection, size estimation, and location of leaks in pipelines using a closed-loop boundary feedback estimator constructed on a real-time transient model (RTTM). In particular, discussed is an energy-based transient pipeline model that includes effects due to terrain topography and multiple leakage points along the pipeline reach; it admits system interconnections and it is appropriate for a real-time execution. Such model was used in a closed-loop boundary feedback estimator of leaks in pipelines. The resulting system was tested with real-time data obtained from a Supervisory Control and Data Acquisition (SCADA) system protecting an actual buried and branched 60-km length steel pipeline transporting liquefied petroleum gas (LPG).
