摘要
Abstract
In order to deal with the safety risks caused by vegetation growth to transmission lines,it selects vegetation samples of pow-er lines and typical power supply corridors in some area in the north for systematic analysis.By integrating the thermodynamic deforma-tion equation of the transmission conductor,it quantifies the maximum relaxation change characteristics of the wire under different meteorological conditions,and then constructs the three-dimensional space safety margin evaluation system of the transmission and dis-tribution channels.Based on the Richards growth function,it can accurately calculate the canopy development trend of the vegetation in the target area in the specific growth period.By dynamically simulating the spatial-temporal coupling relationship between vegetation growth and the state under different meteorological conditions of power lines,it constructs the tree barrier warning model,so which realizes the visual warning and quantitative evaluation of vegetation risk in the transmission corridor.The method effectively prevents the discharge accident caused by the vegetation intrusion limit and the line deformation,and provides the technical support for the reli-ability management of the power grid system.关键词
