    Abstract: Ice disasters on power transmission lines can easily lead to accidents, endanger the safe operation of the power grid and bring economic losses. Therefore, it is important to make short-term predictions of icing conditions on transmission lines. A time series model prediction method combining meteorological factors and the amount of icing on the wire is proposed. First, a data set consisting of five meteorological factors and the amount of ice covered by the traverse is established. Secondly, the long and short-term memory network algorithm is used to train the prediction model. Finally, the model is optimized and evaluated using the actual operating data of the line. The experimental results show that the proposed method can accurately and effectively predict the development of icing on the line, and the prediction error is only 4.2%.
    Key words: transmission line; icing prediction; meteorological information; long and short-term memory network
