传统的对于电力系统连锁故障的研究仅限制在电力网络,很少考虑电力网络和通信网络间的交互作用.以IEEE 118节点系统和新英格兰39节点系统为例,基于直流潮流模型建立了较为符合电力系统运行实际的电力网络和通信网络交互作用模型,通过调节相关参数研究了电力通信网络不同的路由策略对于电力系统连锁故障大停电的影响,并结合复杂网络的理论讨论了复杂网络之间的内在相似性.仿真结果表明通过调整通信网络参数设置恰当的路由策略,可以降低大规模连锁故障的概率.而且在不同电力系统下仿真发现,网络间最优相似策略是相同的,采用该相似策略可以有效地降低大规模连锁故障的概率.%The conventional research on cascading failures in the power system is only limited in the physical power grid,in which interactions between power grid and communication network are seldom considered. With IEEE 118-bus system and New England 39-bus system as examples, the model of interaction between power grid and its communication network in accord with the practical power system is presented based on the DC power flow model. The impact of various routing strategies on the cascading failures of power system is investigated by adjusting the responding parameters of communication network and the inter-similarity between coupled networks is discussed based on the complex network theory. Simulative results indicate that, with proper routing strategy of communication network, the probability of cascading failures of power system can be reduced and the optimal inter-similarity strategy between coupled networks of different power systems is same,which can be adopted to effectively decrease the probability of large-scale blackout.
