摘　　要：配电物联网的快速发展,使得电力物理网与电力通信网耦合程度进一步增强。电力通信网单一故障会交叉影响到电力物理网乃至整个配电物联网的稳定运行,因此,开展电力通信网的节点重要度评估具有重要的理论和现实意义。首先,基于国内某配电物联网试点城市配网拓扑,建立了包含环网柜、开闭所以及分支箱等元件的电力通信网模型;其次,计及电力物理网与电力通信网的耦合机理,基于复杂系统理论建立电力通信耦合网络模型;再次,结合基于复杂系统理论的电力通信网节点重要度评估指标集,提出基于正态云组合权重法与变权重系数的节点重要度评估机制,实现电力通信网节点重要度评估;最后,以国内某配电物联网试点城市配网为算例,建立通信网OPNET仿真模型,验证了该研究所提节点重要度评估方法的有效性。The rapid development of the distribution Internet of Things(IoT)has further enhanced the coupling between the power physical network and the power communication network.A single failure of the power communication network will interact on the stable operation of the power physical network and even the entire distribution IoT.Therefore,the evaluation of important nodes in the power communication network has theoretical and practical values.First,based on the distribution network topology of a domestic city where the pilot project of power distribution IoT is launched,in this paper,a power communication network model including ring network cabinets,switching stations,and branch boxes is established.Secondly,the coupling between the power physical network and the power communication network mechanism is taken into account,and a power communication coupling network model based on the complex system theory is established.Moreover,combined with the power communication network node importance evaluation index set based on the complex system theory,a node importance evaluation mechanism based on the normal cloud combination weight method and variable weight coefficients is proposed,so that the node importance evaluation of the power communication network is realized.Finally,the distribution network of a domestic power distribution Internet of Things pilot city is taken as an example,a communication network OPNET simulation model is established,and the effectiveness of the node importance evaluation method proposed in this paper is verified.
