Transient Simulations for Gas Pipeline Networks

All the transient simulation methods for gas pipeline networks are analyzed comprehensively in this paper, with the descriptions of the advantages and disadvantages of each kind of method. The simulation models, the expressing and processing ways for the initial and boundary conditions, and various kinds of elements and nodes are discussed for the implicit method and characteristic method, which are the most common used ways in the modern transient simulation softwares for the gas pipeline networks. Finally, a real gas pipeline network example gives the transient simulation results of implicit and characteristic methods respectively.
