Combined with the topology structure of Qinghai power communication network, an evaluation method based on the entropy measure is used to measure its invulnerability. Firstly, node importance and link importance are quantified through this method, then, power communication network invulnerability is calculated. The proposed method is applied to Qinghai power communication network and the invulnerability of part of the network is researched and analyzed.
