Abstract: In view of the weak reliability and poor anti-attack performance of vulnerable nodes in the current power communication network, this paper proposes a new method for vulnerability node protection of power communication network based on the model of invalid proximity of edge. This method is based on the index system analysis of the power system and power communication network, network transmission and physics to build vulnerability evaluation model of communication network. According to the time delay and bandwidth ratio, as well as the physical failure rate index in the process of edge traffic transmission, the network components, i.e., node and the invalid proximity of edge, are evaluated, and the final vulnerability evaluation value is obtained by combining the system loss degree after component failure. The experimental results show that the proposed method can effectively protect the vulnerable nodes of power communication network and has reliability.
