摘要
为了对电力通信网络中节点重要度作出准确的评价,提出了一种基于通信网络拓扑和电力因素这两个方面对节点重要度进行综合评估的算法。从通信网络拓扑角度对节点进行重要度评价时,在节点收缩法的基础上,加入了割点的因素,对网络中的割点进行更高权值的赋值,更好地体现网络中的关键节点和非关键节点的差异。同时结合了电力网络的特点,加入了站点等级、站点规模、负荷等级和负荷大小这四个电力因素,对电力通信网络中的节点重要度进行客观评价。结果表明,与节点收缩法相比,能更好地区分电力通信网络中的节点重要度,对电力通信网络中的节点重要度评价具有较大的参考价值。
In order to make an accurate evaluation of node importance in the power communication network,an algorithm based on the communication network topology and the power indicators was proposed to evaluate the importance of the nodes. On the basis of the node contraction algorithm,the fact of cut points was introduced to assign higher weight to cut points in order to reflect the difference between the key nodes and the non-key nodes in the network. Simultaneously,combined with the characteristics of power network,four power factors including the power station level and size,load level and size were added to objectively evaluate the node importance of power communication network. Compared with the node contraction algorithm,the results show that the algorithm in this paper can better distinguish the importance of nodes,and had great reference value for the evaluation of node importance in the power communication network.
