The paper presents modeling of steady run operations of an air pipeline section and simulation of compressor operations. Modeling of steady run operations of an air pipeline section was based on equations of steady run regime of air flow in the pipeline and distribution of pressure in stationary isothermal air flow in the pipeline. Thus it became possible to determine the commercial air (gas) flow rate. The compressor plant creates pressure that is used to move air along the pipeline, forcing air to pass from the low-pressure area to the higher-pressure area. Dependences of compression ratio and specific power on the input air parameters and the number of revolutions of impeller shaft are the model of compressor operation.
