Abstract
Modeling and simulation of natural gas transmission and distribution networks aims to identify and predict the behavior of gas flow so as to perform better monitoring and managing of gas networks. To predict the rate and pressure of gas flow the classical models still use the partial differential equations. In this study, a relatively new approach based on an electrical analogy has been presented which leads to an algebraic and a first-order ordinary differential equation. The solution to these equations is simpler and faster relative to the partial equations. In the proposed model, the effect of pipeline inclination has been considered. To improve the level of predicting mass storage inside the pipe elements, a correction factor in the capacitor equation is also used. The model validation is carried out by comparing the results with some available experimental data and published numerical simulation results, which shows a very good agreement.
