Mathematical modeling of gas flow distribution process in the gas transportation system of Armenia

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
