Nowadays most of the gas fields in Western Siberia are at the final stage of development. To extend the cost-effective gas production at the final stage of development modern technologies are introduced at the fields. One of these technologies is the technology of distributed gas compression. As a result, a multiple increase in the electrical load is observed and new power transmission lines and substations are being constructed to provide electricity to gas fields. For example, at Vyngapurovsky gas field MCU (9 PCs) were to be put into operation and the 6 kV OHL with a length of 22 km were needed to be built, at Yamburg gas field at the moment MCU (52 PCs) are to be set up and it is required to build the 10 kV OHL with a length of 480 km. Thus, the purpose of this paper is to conduct an experimental study of the existing supply and distribution grids of the gas fields’ power supply system in Western Siberia. To achieve this goal the following tasks have been solved: the method of the mathematical models development was selected; the main influencing factors on the voltage class were identified; variation ranges of the selected factors were defined; the optimization of the power supply schematic diagrams for the choice of voltage with minimal discounted costs was completed by the computer program PRON. The problems have been solved using the empirical method (measurement, comparison) of the study, the method of experiment planning (full factorial experiment), and computer programming methods. The analysis shows that all distribution grids of the power supply system in Western Siberia need to be converted to a higher voltage class of 20 kV or the additional overhead lines should be built.
