In this study, the invulnerability performance of power communication network is elaborated in detail firstly, which is considered to be measured by two parameters of robustness and network efficiency. Then, the actual power communication data network model and power communication transmission network model are constructed. On this basis, different attack modes are selected, and the invulnerability performance of power communication network is analyzed through simulation experiments. Finally, experiments show that the impact on network invulnerability caused by selective attacks on important nodes is far greater than that of random attacks, and parameters of robustness and network efficiency can be used to measure the invulnerability of power communication network. In addition, the research results show that the node's invulnerability can be measured by the degree of network efficiency decline, and the greater the network efficiency decline, the better the node's invulnerability, corresponding to more important nodes in the whole network.
