Abstract

Natural gas pipeline networks gradually show a trend of system complexity. The complicated topological structure of natural gas pipeline network is likely to cause inherent structural defects, which has critical impacts on the safe operation of natural gas pipeline network. In order to understand the complexity of natural gas pipeline network and its behaviors when facing structural changes, this paper studies the complexity of natural gas pipeline network based on complex network theory. The complexity analysis results in this paper show that when the gate station is used as the expression scale, natural gas pipeline network has the small-world characteristics. This paper also creatively studied the structural characteristics of natural gas pipeline network, and defined the expression of natural gas pipeline network structure. The research results show that the 3-3 structure and the 3-4 structure are the main structures of natural gas pipeline network, which is of great significance to the future research of natural gas pipeline network.
