Modeling and analysis methods for early detection of leakage points in gas transmission systems (2504.06809v1)

Abstract: Early detection of leaks in gas transmission systems is crucial for ensuring uninterrupted gas supply, enhancing operational efficiency, and minimizing environmental and economic risks. This study aims to develop an analytical method for accurately identifying leak locations in gas pipelines based on unsteady gas flow dynamics. A novel approach is proposed that utilizes pressure variations at the inlet and outlet points to determine the minimum fixation time (t = t1) required for real-time leak detection. Through mathematical modeling and numerical analysis, the study demonstrates that the ratio of pressure drops at different points along the pipeline can be effectively used to pinpoint leakage locations. The results indicate that the proposed method significantly improves detection accuracy and response time, making it a viable solution for integration into gas pipeline monitoring and control systems.
