Power grid bird trouble map drawing method and system based on winter visitor migration route and habitat

Abstract

The invention discloses a power grid bird trouble map drawing method and a system based on a winter visitor migration route and a habitat. In the method, according to a user instruction, a power grid bird trouble map drawing area range is set; winter visitor migration route vector map layer data, winter visitor habitat (such as a water area, a wetland, a farm land, a village and a small town) vector map layer data, winter visitor habitat surrounding line tower coordinates and bird trouble happening frequency data are acquired; according to the acquired winter visitor migration route and habitat vector map layer data, GIS buffer analysis is carried out, GIS interpolation analysis is carried out on historical bird trouble fault data, corresponding thematic maps are obtained, the two maps are integrated, and reference bird trouble risk levels are ranked from low to high, and a power grid transmission line bird trouble map is finally generated and outputted. Important reference can be provided for management decision on anti-bird trouble systems such as an anti-bird sting and an anti-bird baffle arranged on the tower of the power grid, bird trouble tripping accidents can be effectively prevented from happening to the transmission line, and economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of drawing a power system environmental disaster distribution map; in particular, it relates to a method and system for drawing a power grid bird damage map. Background technique [0002] Some provinces in southern my country have relatively high winter temperatures, which are more suitable for winter migratory birds. Every winter, a large number of winter migratory birds fly south along their migration paths to survive the winter. Birds need to rest and forage during migration, and the overhead lines and towers of the power system and nearby habitats (note: living environment, the same below) are often suitable places for them to stay and forage. The guano produced by staying and foraging on the poles and towers can easily lead to distortion of the electric field near the insulators, thereby causing flashover and tripping accidents on the line. According to statistics from the relevant departments of the So...

Problems solved by technology

Birds need to rest and forage during migration, and the overhead lines and towers of the power system and nearby habitats (note: living environment, the same below) are often suitable places for them to stay and forage. The guano produced by staying and foraging on the poles and towers can easily lead to distortion of the electric field near the insulators, thereby causing flashover and tripping accidents on the line. According to statistics from the relevant departments of the Southern Power System, the number of tripping accidents caused by these winter migratory birds has been increasing year by year in recent years. and account for more than 70% of the bird damage accidents in the power grid. However, in the existing technology, the work of bird damage prevention in the power grid mainly relies on the operation experience of relevant staff, lack of scientific and effective management methods, and it is easy to cause the bird damage prevention work to be untimely. , not in place, so a bird damage map based on bird migration paths and habitats is needed to guide which lines and towers of the power grid need to install bird-proof devices such as bird-proof thorns and bird-release baffles

[0003] In short, the current practice of relying on manual operation experience to divide the risk level of bird damage areas and draw the bird damage map of the power grid is lack of scientific basis, and a more scientific method and system for drawing the bird damage map of the power grid that is more in line with the actual operation of the power grid is needed
