High-voltage overhead transmission line typhoon disaster prediction method based on classification decision tree

Abstract

The invention belongs to the technical field of high-voltage transmission line natural disaster prediction, and particularly relates to a high-voltage overhead transmission line typhoon disaster prediction method based on a classification decision tree. In order to overcome the defect that a traditional typhoon disaster prediction method is not high in accuracy is overcome, the invention adopts the following technical scheme: the prediction method comprises the following steps: S1. selecting a typhoon disaster influence factor of the high-voltage overhead transmission line; S2, constructing ahistorical typhoon disaster fault point influence factor database of high-voltage overhead transmission line; s3, performing typhoon disaster prediction model training by adopting a classification decision tree; and S4, performing typhoon disaster prediction by adopting a typhoon disaster prediction model and combining the target high-voltage overhead transmission line and typhoon prediction data.The method has the advantages that the influence of typhoon disasters on the high-voltage overhead transmission line can be accurately predicted, and therefore disaster prevention and reduction workcan be scientifically guided.

Description

technical field [0001] The invention belongs to the technical field of natural disaster prediction for high-voltage transmission lines, and in particular relates to a typhoon disaster prediction method for high-voltage overhead transmission lines based on a classification decision tree. Background technique [0002] High-voltage overhead transmission lines are one of the most important infrastructures in modern society, and they are used to transmit large-capacity electric energy from the power source side to the load side over long distances. High-voltage overhead transmission lines are generally located in the wild, and are severely affected by natural disasters. Typhoons can cause damage to large-scale high-voltage overhead transmission lines in a short period of time, posing a serious threat to the safe and stable operation of the power grid. [0003] By predicting the typhoon disaster of high-voltage overhead transmission lines before the typhoon comes, it is helpful fo...
