(371y) Real-Time Monitoring, Fault Detection and Diagnosis for City Gas Pipe Networks

Korea is the second largest importer of LNG in the world [BP 2009]. LNG is gasified and distributed through the country-wide gas pipe network, which is more than 2,000 km long. Korea Gas Safety Corp and local distributors have been in charge of monitoring the conditions of operation and health of gas pipe networks, mainly based on manual methods. This work is focused on the automation of real-time monitoring, fault detection and diagnosis for city gas pipe networks as a way to reduce the operational cost as well as to increase the reliability and safety of pipe network operations. Wireless sensor networks was adopted to collect the data on operation and gas leaks. Simulation study was investigated to confirm the accuracy of the suggested method of localization of leaks.
