Abstract

Disclosed is a transmission project site and line selecting method based on GIS space information. According to coordinates of an area to be selected of a transformer substation and a line design end point, integrated optimization is carried out on the transformer substation and the line. The method comprises the steps of (1) meshing the area to be selected of the site location of the transformer substation, (2) removing the infeasible area of the site location of the transformer substation, (3) automatically generating an initial path of the line of a site location plot, (4) automatically sorting preliminary schemes of the transformer substation line based on the GIS, (5) performing scene investigation, and verifying and optimizing the line path, (6) performing statistic on to-be-compared schemes of the transformer substation line, and (7) performing technical skill comparing and result outputting. According to the site location selection and line path integrated optimizing method based on the GIS space information, the difficulty of manually selecting the site location and the line path at present is avoided, and the functions of automatic selection and sorting of the site location of the transformer substation, automatic generating of the path, statistic of path length and the number of corners, judgment of line complex terrain, technical skill comparing and the like can be achieved.

Description

technical field

[0001] The invention relates to the technical field of substation site selection and line optimization, in particular to a method for site selection and line selection of power transmission projects based on GIS spatial information. Background technique

[0002] The site selection of the substation project and the route selection of the corresponding lines are the basis of the substation station design and the detailed design of the lines, and also determine the investment and construction costs of the substations and lines.

[0003] In existing power grid planning and design, substation site selection is part of the planning content, while line path selection is part of the power grid design content. Since power grid planning and design are two consecutive processes in the work process, there are very few intersections, so the traditional The best way is to first determine the site of the substation, and then use the site of the substation as an end point of...
