In this paper modeling of the turbocompressors of a gas pressure increasing station has been done at the design point and out of the design point. First the performance characteristics of the station have to be determined, after that with changing the physical properties of the inlet gas and changing the performance characteristics of the used setups with usage of their characteristic curves, the out of the design point modeling and analyses is done. To do this modeling, MATLAB and Aspen HYSYS softwares have been used parallelly. Thus the results of the codes that have been written in MATLAB software can be compared with the Aspen HYSYS software results. After the modeling is done working points of the station are determined. By determining the position of working points on the characteristic curves of the station setups, the equilibrium working range of the station is achieved. Thus in practice if the station's working point is near to this range, the efficiency of the station will be higher and problems like surge will not occur.
