To evaluate the risk system of power communication transmission network (PCTN) scientifically, this paper puts forward an improved k-means clustering algorithm in allusion to the issue of the power device risk value in the PCNT. Both the rating of the device status and the importance of the device determine the power device risk value, among which the importance of device is decided by the number and type of tasks it bears. Since generated randomly, traditional initial clustering centers is easy to lead the result to a partial best instead of global. Therefore, this text uses an improved Huffman tree method based on adjusted cosine similarity to make sure the initial centre. It is verified that the improved k-means clustering algorithm can do better in clustering data, dividing the risk rank scientifically, which provides a reference frame for risk evaluation.
