GIS-Based Drawing Method for Wide-Range Transmission Line Icing Distribution
In view of the complexity of drawing distribution maps of ice region and the low precision of the models,this paper analyzes the long-term meteorological records in Guizhou.Extract the related factors for transmission line icing ; use GIS spatial analysis method to conduct the correlation verification of the icing factors; establish terrain factors database; rasterize the related factors; analyze various factors using the method of multiple regression spatial geometry.Thereupon,the conductor ice-coating characteristics are classified,and transmission line ice distribution model is established.This paper started from the formation mechanism of ice and snow disasters and accidents,and made correlation analysis of various meteorological factors.It solves the key technical problems in drawing large-area transmission line ice distribution maps.The established model helps to obtain the transmission lines ice distribution map of Guizhou region,and accurately simulate the ice distribution regularity in Guizhou.
