An Automatic Discrimination Method for Hidden Tree Barriers in Passages of Overhead Transmission Lines

Abstract

The invention belongs to the technical field of hidden trouble prediction and management for trees in the passage way of an overhead transmission line and specifically relates to an automatic identification method for the tree obstacle hidden troubles of an overhead transmission line passage way. The method comprises the steps of carrying out the field survey to establish a tree obstacle hidden trouble identification reference system in combination with provisions on the safe operation of overhead transmission lines all over a whole network; for any tree with a hidden trouble, selecting a corresponding tree height growth prediction model to calculate the minimum clearance distance of the tree based no the natural growth rules of the tree; in combination with the tree obstacle hidden trouble identification reference system, constructing a tree hidden trouble prediction model for the transmission line passage way to realize the automatic identification of tree obstacle hidden troubles. The above method is used for guiding a line operating department to formulate state inspecting and hidden trouble eliminating strategies for tree obstacles around the overhead transmission line. Meanwhile, the method provides a decision-making foundation for an administrative department to conduct the management operation on transmission line passage ways.

Description

[0001] 1. Technical field [0002] The invention belongs to the technology in the field of prediction and management of hidden dangers of trees in passages of overhead transmission lines, and in particular relates to an automatic identification method for hidden dangers of trees in passages of overhead transmission lines. The tree barrier hidden danger elimination strategy and deployment governance work provide the basis for decision-making. [0003] 2. Technical background [0004] In recent years, my country's forestry industry has developed rapidly, coupled with the implementation of the national policy of returning farmland to forests and the improvement of environmental protection requirements, whether it is a new line or a line that has already been put into operation, the problem of trees under the transmission line channel that threatens the safe operation of the line has become very important. protrude. When trees grow within a safe distance of the transmission line, l...

Problems solved by technology

On the one hand, it is time-consuming and labor-intensive to identify hidden tree barriers through manual line inspection, and there are large human errors; on the other hand, the identification process of hidden tree barriers involves multiple departments, and the level of hidden dangers can only be determined after reporting and approval layer by layer , the processing cycle is longer, which is not conducive to the safe operation of power lines
