Abstract
Efficient natural gas trunkline transportation in conditions of gas trunklines load reduction accompany increasing complexity of technology and natural gas traffic management systems improvement. An important role is given to development dispatching management systems one of which trends is implementing practical research of equipment results based on advanced mathematic models and technologies. Increase applied information systems use for solving problems of gas trunkline equipment effective operation. Priority sci-tech challenge of PJSC «Gazprom» is improving technologies of gas trunkline transportation. In this regard, one of the most promising areas of research is mathematic models and forecasting volume of pumping natural gas through main pipelines methods development for solving rationing problems and dispatching management planning. Earlier prediction technology focus mainly on the stationary conditions and use specific natural gas consumption norms for technological needs of compressor stations. Modern conditions of gas transmission system functioning characterize by decreasing pumping volumes of natural gas each year. Decreasing pumping volumes and increasing inequality of gas supply may cause increasing gas consumption for pumping needs and reducing economic indicators due to changing operation parameters of compressor stations. The paper evaluate the type of data distribution in terms of pumping gas through three thread corridor gas trunklines through which 1/5 of the total natural gas produced in the Russian Federation is pumped. Recommendations on estimates natural gas pumping volumes in case of declining load of main gas pipelines obtained.
