摘要
在工程实践中,多气源的燃气管网各气源的燃气组成不尽相同。在水力计算中,应给气源赋予相应的燃气组成,水力计算的结果才准确。提出气源份额的概念和计算方法——逐次扩展法,分析考虑气源份额的多气源燃气管网水力计算的计算步骤。经算例验证,利用逐次扩展法计算节点、管段的气源份额可行,考虑气源份额的多气源燃气管网水力计算的方法计算结果准确。
In engineering practice,the gas composition of each gas source in a multi⁃source gas pipeline network is not the same.In hydraulic calculation,the result of hydraulic calculation is accurate only when the corresponding gas composition should be assigned to the gas source.The concept and calculation method of the gas source share-successive expansion method are proposed,and the calculation steps of the hydraulic calculation of multi⁃source gas pipe network considering the gas source share are analyzed.It is verified by examples that it is feasible to calculate the gas source share of nodes and pipeline sections by using successive expansion method,and the results of hydraulic calculation of multi⁃source gas pipe network considering the gas source share are accurate.
