Abstract
The issues of enhancement the methods of calculation and design of the gas transportation system (GTS) in the Republic of Armenia and the Republic of Artsakh are considered, taking into account the analysis of loading modes and the peculiarities of the system individual nodes’ operation. To calculate the pressure distribution at the nodal points and gas flows, the matrix method for determining the material balance equations for the linear-independent and nonlinear-independent contours of the gas pipeline circuit is used as a process mathematical model. On the energy conservation law basis, the balance capacities equation of gas supply sources and its consumption, distributed among the gas transmission network elements, is proposed. A mathematical model of the gas distribution process is obtained. Calculation methods that allow increasing the economic efficiency of GTS operation under optimal terms of GTS development are proposed.
Highlights
Armenia is among the countries that import consumed fuel and energy resources (FER)
Analysis of the primary energy resources consumption structure gives an opportunity to state a high share of imports of fuel and energy resources: 90.6...94.0%, while a significant part is natural gas
To increase gas supply efficiency, it is proposed to build an additional section of the main gas pipeline, thanks to which it becomes possible to loop the two gas transportation system (GTS) into a single gas transmission system, which will permit the use of gas from the third source-the underground gas storage station of Armenia (SPCG) in Abovyan for all the regions of the Republic of Armenia and the Republic of Artsakh, as well as the reverse of Iranian natural gas in case of force majeure situations in the supply of Russian natural gas through the GTS of Georgia

Points 1 and 2 of these work stages can be performed simultaneously and contemporary methods of calculation and computer aided design using software can be used for the point 2
