摘要
为了应对青海省电力调度数据网由于扩展而导致的复杂性和脆弱性,以三层网络分层为基础,分析了复杂网络模型下无标度网络和小世界网络特性,按拓扑结构将某区域电力调度数据网分为双星形和网状结构,讨论了在几种网络被破坏的环境下两种结构的脆弱性表现。结果表明,具有无标度特性的星形结构对蓄意破坏表现脆弱,网络连通性差;具有小世界网络的网状结构对蓄意破坏表现坚强,但易发生连锁故障。
In order to solve complexity and vulnerability due to the network expansion of Qinghai electric power dispatching data network, the dynamic behaviors of scale-free network and small world network derived from complex network model are analyzed based on the three-layer networks theory. According to the topology of complex network, a regional electric power dispatching data network is classified as double star structure and mesh structure, vulnerability performance under two kinds of topologies in several types of network attack is analyzed. The results show that the star structure characteristics of scale-free network is vulnerable to deliberate attack, and poor in network connectivity; the network structure characteristics of the small world network is strong when suffering sabotage, but is prone to cascading failures.
