Leak detection and localization of gas pipeline system based on full dynamical model method

Pipelines are of great importance to gas and petrochemical industries. Frequently, they are used to transport gas by hundreds or even thousands of miles. It is a very important task to keep the gas pipeline under safety operation. Leak detection and localization mechanisms play an important role in the management of a gas pipeline system. In this paper, a model-based leak detection and localization algorithm was proposed. In order to test the performance of the proposed method, a practical test rig has been built. The experiment results show that accurate and robustness leak detection and localization can be achieved using this method.
