A Graph Theory-based Site Selection Method for Mountain Fire Emergency Points of Transmission Lines

Abstract

The invention discloses a power transmission line forest fire emergency point site selection method based on a graph theory. The power transmission line forest fire emergency point site selection method comprises the steps of (1) dividing power transmission line forest fire prone and frequent regions, (2) selecting possible power transmission line forest fire frequent sites, (3) establishing a power transmission line forest fire emergency point site selection graph theory model, (4) establishing a mathematical power transmission line forest fire emergency point site selection model, (5) solving the mathematical power transmission line forest fire emergency point site selection model, and (6) selecting power transmission line forest fire emergency points. The power transmission line forest fire emergency point site selection method based on the graph theory has the advantages that the shortest time between the possible power transmission line forest fire frequent sites is calculated based on the graph theory, the power transmission line forest fire emergency points are selected scientifically and economically by use of the method so that a power transmission line forest fire emergency team can hurry to a forest fire site, and therefore, the influence of the forest fire on the power distribution line can be minimized and an efficient and economic technical method is provided for quickly putting out the power transmission line forest fire.

Description

technical field [0001] The invention relates to the technical field of transmission line mountain fire prevention and control, in particular to a graph theory-based site selection method for transmission line mountain fire emergency points. Background technique [0002] With the country's strong support for the "returning farmland to forest" policy, barren mountains and wasteland are gradually covered by vegetation, and power transmission lines inevitably pass through dense vegetation. In the south of our country, extreme weather, farmers' spring plowing and burning, and Qingming ancestor worship activities have led to frequent wildfires. Wildfires cause heavy losses to national properties such as forests, especially near power transmission corridors, which can cause transmission lines to trip, seriously threatening the safe and stable operation of the power grid. [0003] The power grids in North China, Central China, and East China are interconnected through AC UHV. Once ...

AI Technical Summary

Problems solved by technology

Due to the lack of address layout methods for mountain fire emergency points on transmission lines, the emergency team for mountain fires on transmission lines often loses sight of one another during the fire-fighting process, and the operating cost is high. There was a situation where the emergency team was on the way to the scene, and the transmission line had already tripped due to a mountain fire.
