An early-warning method for power line channel tree-bamboo discharge based on temporal and spa-tial evolution
In order to solve the problem of low accuracy of tree-bamboo discharge early warning in transmis-sion line channel,a tree-bamboo discharge early warning method based on temporal and spatial evolution is proposed.Firstly,the image of transmission line channel is collected by UAV nest,and the image noise is filtered.Secondly,the types of bamboo are identified by the edge characteristics of the bark and leaves,and the temporal and spatial evolution analysis is carried out based on the growth rate of typical bamboo trees and the observed actual growth rate,so as to predict the potential discharge time of bamboo trees and give early warning.Finally,the simulation results of a city power supply company show that the accuracy of the proposed method is 98.9％.The simulation results of the example show that the proposed method can accurately identify the potential discharge hazards of the transmission line channels and improve the opera-tion and maintenance management level of the transmission line channels.
