REMOTE BASED MULTI-CHANNEL LEAK MONITORING SYSTEM USING CORRELATION
Oil and gas transportation pipelines are the key equipment in petroleum and chemical industry. At the heart of the leakage monitoring and detection procedures are the report of leakage event timely and of leakage point precisely. This paper presents a more realistic approach for using rarefaction-pressure wave technique in oil pipelines, which aims to two targets, one is the improvement of remote and intelligent degree, and the other is the improvement of the leakage location ability. It also introduces a basic concept and structure of the remote based multi-channel leak detection system. Primarily, an SVD embedded leakdetection package is designed to exchange the diagnostic information with the PLC data package of Modbus protocol, and then via fiber network, the SCADA-based remote monitoring and leak detection system is realized. The applied results show that the whole running status of pipeline can be monitored effectively, and a higher automation grade and an excellent leak location precision of the system can be obtained.
