摘要
利用图论相关知识,对城市燃气管网的系统结构可靠性(连通可靠性)进行了尝试性研究,分别从用气节点连通可靠度和管网系统连通可靠度两个角度定量分析了环状管网的拓扑结构对管网稳定运行的影响,并利用管道的连通重要度来定量评价不同位置的管道对管网系统连通可靠度的贡献。
The safety and reliability of urban gas pipeline concerns the regular energy supply of the whole city and normal producing managing of gas consumers. Regular gas supply is related to not only the structuralreliability, but also the connection type--topological structure of gas pipeline. In this paper, the connectivity reliability of urban networks is analyzed based on graph theory, respectively from aspects of the network system and consumers, and the pipeline connectivity importance is employed to evaluate the contributions of different pipelines for the connectivity reliability of the networks.
