城镇燃气管网的健康评价及规划优化

Health Evaluation and Optimization of Urban Gas Network

摘要:

基于社会网络分析原理和方法，将燃气管网抽象为网络模型.以晋中市中心城区燃气管网为例，在Pajek平台上构建现状与规划网络图.构建由网络拓扑结构、管网运行状态与重点个体设施三方面构成的网络健康测评体系，计算包括网络密度在内的八项指标.计算可知，规划管网拓扑结构较优，现状管网运行状态较优，提出燃气管网拓扑结构优化策略与物理设施维护方案.

Abstract:

The gas network can be abstracted as network model by social network analysis（SNA）.Taking the gas pipeline of the central city of Jinzhong as an example, this paper constructed the current network and planning network on Pajek. The network structure evaluation system was constructed including the topology structure, operation status and key facilities. Eight indexes including network density were calculated. The results show that the current gas network has a better operation while the planning has a better topology structure. The strategy for the network structure optimization and physical facility maintenance was proposed.
