Leschenko I. Analys of gas pipelines systems regimes with the account of capital equipment technical conditions

Dissertation for a scientific degree of Cand.Tech.Sci. in speciality 05.14.01"Power systems and complexes". - Institute of General Energy National Academy of Sciences of Ukraine, Kyiv, 2005. The new logical-mathematical model of system of pipeline transport of gas is developed in which compressor station is represented by one equation of influence. At modeling gas pump aggregate work it is offered to take into account gas turbine and a centrifugal force-pump technical condition. New algorithms for identification of compressor stations equipment technical condition are developed, they are based on the original methods of diagnostics which are operating only in parameters from a regular set and not demanding change of an operating mode of the aggregate. On the basis of developed models and algorithms the computer-based tool for the analysis of gas pipeline systems modes with the account of a technical condition of the capital equipment is created and a computer-based tool for technical condition of compressor stations capital equipment operative diagnostics is created too.
