摘　　要：为提高城市燃气输配系统网络结构抗毁性,针对其结构复杂,功能设备联系紧密,转换节点多等特点,建立网络模型,选取网络模型参数及抗毁性测度指标,对系统在不同攻击策略和模式下的抗毁性进行模拟仿真。研究结果表明:基于节点介数对城市燃气输配系统抗毁性影响最为显著;不同攻击策略下连续移除节点数目越少引起该系统抗毁性的变化越大;破坏初期进行维护是提高系统抗毁性最有效的途径。As you know,the structure of the urban gas transmission and distribution system is complex,the functional equipment of it links closely and with many transfer contacts.In this paper,the network model is established,in which the network model parameters and invulnerability measured indexes are selected to conduct simulations under the different attack strategies and attack modes.The results show that the most striking attack strategy for the invulnerability of urban gas transmission and distribution system is based on deliberate attack of node betweenness and under different attack strategies,the less the number of nodes is removed continuously,the greater the impact on the invulnerability of the system.Routine maintenance is the most effective way to increase the invulnerability of the system.
