| description | The invention relates to a weather forecast-based maximal current carrying capacity prediction method of an overhead transmission line, and the method comprises following steps of S1 collecting a position where the transmission line is located and weather data of past years in the local district; S2 regression analyzing a relation between ambient temperature, wind speed, wind direction and solar radiation quantity of the position on which the transmission line is located and weather data of the local district; S3 predicting a weather condition on the position where the transmission line is located through a formula according to the weather forecast of the local district of the transmission line; and S4 substituting the predicted weather condition in step S3 in a calculation formula provided in the international standard IEE738-2006 to calculate the maximal current carrying capacity prediction value of the transmission line. Against for the problem for predicting the maximal current carrying capacity of the traditional transmission line, by establishing the associated link between the on-site weather condition and the weather forecast data, the maximal current carrying capacity of the transmission line is predicted by utilizing the weather forecast data. |
