Relationship Between Defects of Capacitive Equipment and Geomorphology

In the power system, there are a large number of capacitive devices, accounting for 40% to 50% of the total substation equipment. The healthy operation of capacitive devices is vital to the power system. With the vigorous advancement of power grid information construction, various types of power data have exploded, which has provided strong data support for the healthy operation of capacitive equipment. There is little research on the relationship between the defects of capacitive equipment and topography at home and abroad, such as altitude, slope, and aspect. This project conducts research on the relationship between defects of capacitive equipment and topography, and provides technical support and assistance for decision-making of power system construction. Firstly, 60 TIFF images with a resolution of 30m were obtained from the website, and 60 images were stitched using ArcGIS software, and then the slope and aspect data of the target location were extracted based on the latitude and longitude information. Secondly, we perform data cleaning and code on the original data. Thirdly, the relationship between the number of occurrences of equipment defects and altitude, slope, and aspect is programmed. The correlation is roughly deduced by calculating the number of occurrences of equipment defects and the parameters such as the covariance, correlation coefficient.
