摘　　要：在传统水力分析的基础上,充分考虑多气源燃气密度及动力黏度不同带来的管内流动特性的差异,提出气源分配系数来准确分析燃气管网的水力工况,分析稳态工况下各气源在管网内的流量分配及终端用户的燃气性质,结合案例对模型的有效性进行验证。On the basis of the traditional hydraulic analysis, fully considering the different flow characteristics in pipes caused by various gas densities and kinetic viscosities of multiple gas sources, the gas source distribution ratio is put forward to accurately analyze the hydraulic regimes of the gas pipe network. The flow distribution of each gas source in the pipe network and the gas quality at end users under steadystate conditions are analyzed, and the effectiveness of the model is verified by the case.
