Bozhinskiy I. Models and technique of on-line control of regional gas supply systems

The thesis is aimed at solving the actual problem of working out mathematical models and techniques of operative dispatch control of technological processes in Gas Supply Distribution Systems (GSDS) in the market. Methodology and basic engi-neering solutions of spatially-distributed multilevel control sys-tem of gas sale enterprise was researched and proposed on the basis of geoinformation technologies. Stochastic approach to solving Operative Dispatch Control (ODC) problem of transport conditions and natural gas distribution in GSDS was proposed. The class of tasks of operative dispatch control of transport con-ditions and natural gas distribution in GSDS was defined and its structuring for real-life operative conditions of GSDS was car-ried out. Mathematical model of GSDS essential elements (gas pipeline section and control element) was researched and pro-posed. Structuring of the criterion function and limitations of the task of operational planning of transport conditions and natural gas distribution in GSDS was realized. The criterion of technical durability of regional gas supply systems operative conditions was introduced and formalized. Mathematical formulation, algo-rithm and results of rational conditions planning in gas distribu-tion network were cited based on a number of sources.
