The Study on the Prediction Method of Ice Thickness of Transmission Line Based on the Combination of GA and BP Neural Network

It is very important to forecast the ice thickness of Transmission Line for the safe operation of transmission network. The author had introduced artificial neural network(ANN) to the prediction of the ice thickness of transmission line, and proposed a predictive model based on GA and BP addresses on the defects of BP network includes slow convergence and easiness of running to local minimum, and finally proved that GA-BP model was more effective to predict the ice thickness of transmission line the BP model.
