Informer model-based power transmission line icing prediction method

Abstract

The invention discloses an Informer model-based power transmission line icing prediction method. The method comprises the following steps: collecting data of historical icing, terminal tension, weather station prediction, weather station monitoring, and terminal information, and preprocessing the data; constructing a training set Dtrain, a verification set Dvail and a test set Dtest; performing input unified conversion; generating an encoder; stacking Decoders to better obtain a mapping relation between input and output, and to improve the prediction precision; through a full connection layer, obtaining a final output; performing model iteration until a training condition is terminated, and generating a trained model for predicting a tension value of a power transmission cable at a future moment and through the tension value calculating the icing thickness of the current power transmission cable. The technical problems of low accuracy, low robustness, poor adaptability and the like of a power transmission line icing prediction method in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of power grid icing prediction, and in particular relates to an Informer model-based power transmission line icing prediction method. Background technique [0002] In recent years, with the rapid development of power system and power grid construction, the distribution of power grids has gradually developed in the direction of large-scale and intelligent, and the reliability requirements for power grids are also getting higher and higher. As one of the most common disasters affecting the power system, icing often leads to an increase in the load of the transmission line, which in turn causes problems such as line disconnection, ice flash tripping, and damage to transmission line components. Icing disasters have seriously threatened the stable and reliable operation of the power grid system, brought huge economic losses, and seriously restricted the construction and development of the power grid system.
