Carrying out research work to determine the working conditions and determine the fuel consumption in a gas turbine installation. The descriptions of a gas turbine unit operating on gaseous fuel are presented: in normal and standby operating modes. The optimal operating mode of the gas turbine plant is combined: the production of heat and electricity. A study of the operating mode of a gas turbine unit at a constant pressure of 0.1 MPa and a temperature when air enters the compressor of a gas turbine unit with fuel combustion has been carried out. The features of the use of an energy carrier in a gas turbine unit during the year are highlighted and analyzed. The structure and current consumption of natural gas in a gas turbine unit for accounting for the consumption of energy carriers is described. As a result of the study, a substantiation of the concept of calculating the predictive function for accounting for the costs of non-renewable energy resources for a gas turbine plant, used natural gas, is proposed. This, in turn, ensures effective planning and increasing the economic efficiency of the enterprise. All this makes it possible to regulate the modes and costs of using fuel during the operation of a gas turbine unit. A study of the operating mode of the gas turbine unit at a constant pressure of 0.1 MPa and a temperature of 10 ° C was carried out, when the optimal operating mode of the gas turbine unit is the combined production of thermal and electrical energy. The choice of the predicting function by which it is better to forecast the use of the energy carrier for the current year has been proposed and substantiated. The scientific novelty of the research lies in the formulation of the substantiation of the conceptual principles for the construction of a mathematical model of the use and accounting of energy consumption based on the use of predictive functions and recommendations are provided on how to rationally use natural resources. The practical significance of the work lies in forecasting and calculating the volume of natural gas consumption (thousand m3) by the enterprise for the next year, and this, in turn, allows us to adjust the gas consumption for the future and make informed decisions on how it is possible to reduce fuel consumption or use it as efficiently as possible.
