摘　　要：为确定电力光纤网中关键节点位置并建立重点保护,提出了一种基于三角模融合的网络节点重要性评价方法,该方法将电力光纤网抽象成加权网络模型,综合考虑网络的传输特性和网架特性对网络节点重要性的影响。采用模糊数学理论中的三角模算子对两个特性的重要性隶属度进行融合,强化二者度量指标中的同类信息,协调二者度量指标中的矛盾信息,克服了单一指标度量节点重要性的局限性。仿真结果表明,利用三角模融合能更细致地描述加权网络中各节点重要性差异。In order to identify the location of key nodes and further develop protection strategies in optical network for power grid, a novel strategy of network node importance evaluation was proposed based on Triangle Module. This scheme abstracts the optical networks into a weighted network model, and synthetically considers the impact of the characteristics of the transmission and the grid structure on node importance. Triangle Module operator on fuzzy mathematical theory was used to integrate the two importance characteristics of transmission and grid structure, which has the properties of strengthening the same type of information and harmonizing conflicting information, overcome the limitations of single evaluation indicator which can Simulation results show that the proposed strategy can differentiate the im- portance of network nodes precisely.
