Gate type tower long and short leg land occupation area calculation method, system, equipment and medium applied to digital power grid

Abstract

This invention provides a method, system, equipment, and medium for calculating the footprint of portal towers with varying leg lengths in digital power grids, relating to the field of digital transmission line design technology. The method includes: obtaining the terrain slope and the height and design parameters of each of the eight legs of the portal tower; using the high / low leg slope calculation criterion to obtain the diagonal half-leg opening of each leg; and, combined with the sub-tower spacing, decomposing the total footprint into three parts: the left sub-tower, the right sub-tower, and the middle trapezoid, calculating and summing these parts separately using the high / low leg footprint calculation criterion. This invention abandons the traditional rectangular approximation estimation, significantly reducing calculation errors by accurately calculating the uneven footprint under different terrains and combinations of long / low leg lengths, effectively controlling the land acquisition scope, and improving the accuracy, economy, and environmental benefits of power grid engineering design.
