Natural gas is transported through a network of main gas pipelines under high pressure, and the process of its consumption requires a decrease in pressure of gas laid mainly in throttling devices. It is beneficial to use part of the available energy potential of natural gas for electricity production by means of expander-generator technologies. However, the task of finding ways to increase the capacity and efficiency of gas turbine power units using the energy of excess pressure of natural gas does not lose its relevance. The study poses and solves the problem of developing a new thermal cycle diagram of a combined power unit to substitute throttling pressure regulators at gas distribution stations with an expander-compressor gas turbine unit. A distinctive feature of the unit is the replacement of the gas turbine drive of the air compressor with its drive from the turbo-expander by using the energy of excess pressure of natural gas. This results in significant increase in the absolute thermal efficiency and decrease in the specific fuel and energy costs. We developed analytical dependencies relating the operating parameters of the expander-compressor gas turbine unit and its output characteristics. Thus, it was possible to find an approach to calculating the unit, the approach being based on proven methods for thermal cycle calculation. The results of the performed calculations show that, in comparison with gas turbine units, the expander-compressor gas turbine unit has a significantly lower specific consumption of equivalent fuel and a lower negative impact on the environment

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.

The investigation of vibroacoustic characteristic of gas-pumping units of GTK-10-4 type. Power units improvement, as a rule, results in the decrease of units steel intensity and under conditions of the increase of airgas flows and facilities developed it causes a growth of vibroacoustic activity of plants elements. Taking into account this factor, it is necessary to develop measures to reduce noise and vibrations in sources of their origin at the design elaboration both at the stage of design, and at the stage of reengineering. With this purpose there are carried out the investigations of noise and vibration characteristics of a gaspumping unit of GTK-10-4 type equipped with a sta-tionary gas-turbine unit with a capacity of 10 MWt and a natural gas supercharger of 520-12-1 type manufactured by NZL. The noise and vibration sources of impeller ma-chines are studied, their vibroacoustic characteristics are analyzed, and the methods to reduce vibroacoustic activity of gas-pumping units of such a type operating at compressor stations of trunk pipelines are offered.

This article discusses the method of thermal and exergetic analysis of cogeneration energy sources on the example of the gas turbine unit LM6000PF (GTU-CHPP «Vostochnaya»). The purpose of the conducted exergetic analysis is to determine the most advantageous method for evaluating the performance of equipment in terms of thermodynamic efficiency. The comparison of GTU efficiency values obtained by calculation using the methods of thermal and exergetic analysis is performed. A special feature of the exergetic analysis is the use of an additional indicator as exergy along with energy indicator. In the analysis, the efficiency of using the energy of the fuel burned in the GTU combustion chamber and the working bodies of the gas cycle for the production of electrical and thermal energy is assessed by comparing the actually accomplished work with the exergy of the process
