specific Embodiment 1

[0065] Specific embodiment 1: division of regions across the country:

[0066] (1) According to the administrative regions, the whole country except Hong Kong, Macao, Taiwan and Hainan is divided into 30 initial categories, that is, each provincial administrative region forms its own category.

[0067] (2) According to the satellite monitoring fire point data, the accumulated daily fire point times of each administrative region from January 1, 2001 to December 31, 2012 were counted according to the provincial administrative regions.

[0068] (3) The accumulated daily precipitation of each administrative region from January 1, 2001 to December 31, 2012 was counted according to the provincial-level administrative regions according to the data of surface meteorological observation stations.

[0069] (4), establish an index system for characterizing transmission line risk distribution area division, mainly including 366 indicators of historical cumulative daily precipitation (I 1...

specific Embodiment 2

[0087] Specific embodiment 2: Division of mountain fire risk areas on power transmission lines in Hunan Province:

[0088] (1) According to the administrative regions, the whole province is divided into 14 initial categories, that is, each prefecture-level administrative region forms its own category.

[0089] (2) According to the satellite monitoring fire point data, the accumulated daily fire point times of each administrative area from January 1, 2001 to December 31, 2012 are counted according to the prefecture-level administrative regions.

[0090] (3) The accumulated daily precipitation of each administrative region from January 1, 2001 to December 31, 2012 was counted according to the data of surface meteorological observation stations according to the prefecture-level administrative regions.

[0091] (4), establish the regional division index of characterizing transmission line risk distribution, mainly include 366 indexes of historical cumulative daily precipitation (I...

Abstract

The invention discloses a forest fire risk area dividing method for a power transmission line based on cluster analysis, and belongs to the technical field of power distribution. Based on satellite fire point monitoring data, the method enables a sample sequence to be moved to the other cluster according to a proposed cluster distance index, and obtaining a clustering result through multiple calculation of a clustering distance index and movement, thereby obtaining the forest fire risk area dividing of the power transmission line in a research region, and providing basis for the precise prediction of forest fire of the power transmission line and forest fire prevention of the power transmission line. The method can guide the deployment of fire extinguishing troops and fire extinguishing material operation in a high-prevalence area of forest fire of the power transmission line, and improves the forest fire disposal capability of a power grid.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution, and in particular relates to a method for dividing mountain fire risk areas of power transmission lines based on cluster analysis. Background technique [0002] With the continuous growth of the national economy, the construction of a large number of transmission lines has made the tense situation of power corridors increasingly severe. Many transmission line corridors are inevitably built in areas with high incidence of wildfires. In recent years, frequent wildfires on transmission lines have posed a serious threat to my country's power system. According to the statistics of the power grid company, the situation of the tripping of transmission lines caused by wildfires is becoming more and more severe. However, my country has a vast territory and complex topography, the distribution of vegetation resources is different, and the folk customs are also different from pl...
