An Improved Flow Equation of Gas Pipeline Networks: New Expression Method

Aiming at the problem of the consumable gas at compressor stations uncalculated in the past and the deviated result unavoidable in model describing that part of gas amount nicely in pipeline networks flow equations with incidence matrix method, the paper puts forward a method for improvement by increasing consumable gas source vector, which can describe the consumable gas in the stations completely and give a good picture of the structure and flow equations of pipeline networks properly.
