N2 - Improving the energy efficiency of compressor stations is an urgent problem in the gas industry, as gas compression is the most energy-intensive heat and power-consuming process in the hydrocarbon pipeline transportation. In this regard, it should be noted that uninterrupted power supply to compressor stations is a key factor both for the overall system integrity and for the industry as a whole. Such factors as the growth of power tariffs, ageing of power transmission lines and, consequently, the increase in the number of disconnections due to power line accidents, the high cost of new network construction and difficult climatic conditions in the areas of newly developed fields predetermine the interest in the development of projects to create power plants for own needs. In this thesis compressor station №7 of the "Surgutneftegas" company was chosen as the object for research. The aim of the work was to determine the most advantageous source of power generation both from the technical and economic sides. For this purpose, the theoretical capacity of turboexpander, gas turbine unit and combined cycle gas turbine unit were calculated. The results of thermodynamic and economic calculations are presented at the end of the thesis.
