摘　　要：综合分析了气体管网动态仿真的各种方法,指出了各种方法的优缺点。针对当前较为成熟的隐式法和特征线法,给出了它们的动态仿真模型以及初始条件、边界条件、各类元件和节点的表示与处理方法。针对实际气体管网。分别给出了隐式法和特征线法的仿真结果。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.
