The parameters of transient processes caused by alterations of operation modes and depressurization of the pipeline are studied. Mathematical tools for leak detection based on the data of gas flow parameters measurement and acoustic emission signals have been developed. On this basis, a methodology for monitoring the integrity of main gas pipelines and approaches to automating their management are proposed. Implementation of the results of work will increase the controllability of the GTS, the accuracy of operational balancing of the gas mass, reduce gas losses, and minimize the consequences of uncontrolled depressurization of gas pipelines.   Product Description popup.authors Mishchenko Viktor O Postolaki Lesya I Chekurin Vasyl F popup.nrat_date 2021-01-25 Close
