To improve the efficiency of gas turbine units (GTU) at compressor stations (CS) of main gas pipelines, we studied the influence of outdoor air temperature on GTU capacity; the ability to use the expander-generator to generate electricity; preheating of air and gas entering the gas turbine aiming at fuel saving. A GTU scheme was developed consisting in air heating before the compressor, gas supply through the expander-generator and gas heating after it. We carried out efficiency analysis for both GTU, and CS as a whole.

Abstract
To improve the efficiency of gas turbine units (GTU) at compressor stations (CS) of main gas pipelines, we studied the influence of outdoor air temperature on GTU capacity; the ability to use the expander-generator to generate electricity; preheating of air and gas entering the gas turbine aiming at fuel saving. A GTU scheme was developed consisting in air heating before the compressor, gas supply through the expander-generator and gas heating after it. We carried out efficiency analysis for both GTU, and CS as a whole.
