A method and apparatus for predicting tree barriers of transmission and distribution line

Abstract

A method and apparatus for predicting tree barriers of transmission and distribution line are provided. In the method, firstly, the conditional parameters of the measured trees are obtained, the treeswith different conditional parameters adopt different growth rate values when predicting the growth height, and according to the current tree height and the growth rate values, the tree height prediction value of the measured trees after a preset period of time can be calculated. The method obtains the different growth rate values of trees under different influence factors (such as tree species,tree age, altitude) through the mapping relationship between conditional parameters and growth rate values, that is, through the preset mapping table, so as to quantify the influence factors of tree growth, such as tree species, tree age, altitude, and the like, and incorporate them into the calculation. Because many factors affecting tree growth are quantified through the preset mapping table, the method can accurately predict tree growth, improve the accuracy and accuracy of tree barrier prediction results, and then provide guidance for the development of tree barrier cleaning work.

Description

technical field [0001] The present application relates to the field of tree barrier cleaning of power transmission and distribution lines, in particular to a tree barrier prediction method and device for power transmission and distribution lines. Background technique [0002] In areas where forests grow vigorously, various types of green trees grow all year round under the transmission and distribution lines. As time goes on, the height of the tree increases, and the branches or leaves are easy to contact the line, causing safety problems such as electric shock short circuit and line tripping. For this reason, it is necessary to monitor and predict the growth of trees around the line, so as to clear tree barriers in time and ensure the safety and stability of line operation. [0003] In the prior art, the monitoring and forecasting of the growth of trees often adopts the method of calculating through the growth equation. The method of calculating through the growth equatio...
