Geographic Information System Based on Thermal Aging Data of Transmission Lines

With the continuous expansion of transmission network, how to better detect and manage transmission line network has become the focus of research. This paper uses Matlab to process the thermal aging of meteorological data at different measuring points in a certain region and different periods, and then extends to the analysis of the thermal aging loss of the whole line. Finally, the loss data of each line in the region is imported into the software ArcGIS[1] to form a visual geographic information system based on the thermal aging data of transmission lines. The system can effectively understand the working state and thermal aging degree of transmission lines. In this paper, 109 sets of data were collected and processed in Shandong province, and finally a visualization system which met the expected results was obtained.
