| 摘 要： | 过去使用的关联矩阵方法在描述枝状天然气管网流动方程时,没有考虑压气站的自耗气,这在一些需要准确描述这部分气量的模型中会产生不可避免的偏差.文中通过增加自耗气源向量的方法对此进行了改进,使得该方法可以完整地描述这部分天然气,能更加准确地对管网的结构和流动方程进行描述.

| Abstract: | Consumable gas of compressor stations was not taken into consideration when branched gas pipeline networks flow equations were described with the incidence matrix method in the past, which would result in unavoidable deviation. The method was improved here by increasing the consumable gas source vector, which can be used to describe completely the consumable gas in stations with more accuracy to determine the structure and flow equations of pipeline networks. |
