A Lumped Transfer Function Model for High Pressure Gas Pipelines
49th IEEE Conference on Decision and Control
ISSN or ISBN
In this paper a lumped transfer function (TF) model is derived for High Pressure Natural Gas Pipelines. Departing from a nonlinear partial differential equation (PDE) model a high order continuous state space (SS) linear model is obtained using a finite difference method. An infinite order TF is calculated from the SS representation and finally is approximated by a compact non-rational function. This model is compared with SIMONE®, a commercial simulator of gas transport and distribution, using a case study, and both exhibit a similar accuracy.
