Embodiment Construction

[0032] The drawing of the ice-covered area map of the transmission line is divided into two parts: data collection and drawing. The drawing software takes arcgis as an example.

[0033] 1. Data collection

[0034] The required data are digital elevation and administrative boundary layer files of the region.

[0035] 1.1 Digital Elevation (DEM) of Bureau of Surveying and Mapping

[0036] Digital altitude elevation information collected from survey bureaus.

[0037] 1.2 Boundary layer file of this area

[0038] Collect the boundary layer files of this area from surveying, mapping and meteorological departments as the base map of the ice-covered area map.

[0039] 2. Drawing

[0040] 2.1 Calculation of ice thickness

[0041] In the arcgis software, load the digital elevation (DEM) map that has been partitioned, and then call the arcgis raster calculator tool to call the corresponding formula for different regions and different return periods:

[0042] 1. West District

Abstract

The invention discloses an automatic drawing method for an iced covered area map of a power transmission line. The main content of the automatic drawing method is to automatically generate the ice covered area map of the power transmission line by adopting processes such as a GIS (Geographic Information System) raster calculator, reclassification and raster-to-polygon conversion on the basis of an ice thickness prediction model provided by meteorological bureau and DEM (Digital Elevation Mode) data provided by surveying and mapping bureau. The method provides a means to realize the automatic drawing of the ice covered area map, the ice coverage distribution situation around power transmission and transformation facilities can be accurately reflected by the drawn ice covered area map, all areas are covered, and a basis is provided for construction cost evaluation of newly constructed power transmission line engineering and ice-proof reconstruction of constructed lines.

Description

technical field [0001] The invention relates to an automatic drawing method for an ice-covered area map of a transmission line in a power system; in particular, the elevation element is considered. Background technique [0002] In recent years, the occurrence of icing disasters on transmission lines has increased significantly. Once the line is severely icing or even breaks down the tower, it will cause a large-scale power outage and affect the safe and stable operation of the power grid. The ice-covered area map is the basis for the power system to guide the anti-icing design and transformation of transmission lines. Therefore, the automatic and rapid drawing of the ice-covered area map has become a key problem that needs to be solved urgently for transmission lines. [0003] Icing area map drawing is an important part of improving the power grid's ability to resist icing accidents, and it can guide the anti-icing design and transformation of transmission lines for power gr...
