This essay analyzes the deficiency of existing transmission lines icing thickness prediction method and puts forward an icing thickness forecasting of transmission line based on particle swarm algorithm to optimize SVM. The historical ic- ing growth data samples are used to train support vector machine （SVM）, and the training model is used to forecast icing thickness of the line. At the same time particle swarm optimiza- tion algorithm is used to optimize the key parameters of SVM, effectively improving the icing thickness prediction accuracy ＆ providing a reliable basis for transmission line deicing.
