Annotation:

For most existing leak detection systems (LDS) in pipelines, localization of leaks locations is still an unsolved problem. The main reason for this problem is the limited number of sensors installed on long-distance pipelines. Due to the measurements insufficiency, the exact location of the leak cannot be easily determined. The authors of the presented article consider the use of particles filter method as a "soft" sensor to estimate operating parameters at intermediate points of a pipeline using available measurements at the end points. The difference in readings between the estimated states and actual measurements at intermediate points is used to detect and locate leaks. The proposed method improves the accuracy of leak localization by using intermediate pressure measurements. Simulation results prove the effectiveness of the proposed method.
