Power transmission line ice jump height prediction method and application

The invention discloses a power transmission line ice jump height prediction method and application, and the method comprises the steps: 1, constructing a sample data set: taking the span, height difference, icing thickness, deicing rate and wind speed of a line as input quantities, taking an ice jump height envelope data set as an output quantity, and dividing the obtained sample data set into a training set and a test set; 2, training an ice jump height prediction model: constructing a power transmission line ice jump height prediction model based on a BP neural network algorithm, and 3, testing the ice jump height prediction model: testing the generalization ability of the trained ice jump height prediction model by using the data of the test set; and 4, predicting the ice jump height and an envelope line by using the ice jump height prediction model. The prediction method is applied to calculation of the tower head insulation gap of the tower. According to the method, a simple and efficient ice jump heigh
