Embodiment Construction
[0044] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0045] Such as figure 1 As shown, the transmission line intelligent line selection method based on GIS multi-objective dynamic planning technology described in the present invention, wherein the key point is to deal with a large number of relevant environmental factors, and realizes the automatic acquisition of each geographic environment information based on the GIS geographic information system. The difficulty is to divide the GIS map into grids, quantify the comprehensive weight of environmental factors in each cell, and establish a dynamic programming algorithm minimum cost search model. It includes the following steps:
[0046] The first step is the generation of the transmission line selection path: based on the GIS grid map, t...

The invention relates to a power transmission line intelligent line selection method based on a GIS multi-target dynamic planning technology. Compared with the prior art, the defects that manual line selection is low in efficiency and high in analysis subjectivity are overcome. The method comprises the following steps: generating a power transmission line selection grid map; modeling the line selection cost of the power transmission line; and performing intelligent line selection on the power transmission line. On the basis of a geographic information system, path optimization is carried out by adopting the dynamic planning model, and the new automatic optimized wiring method for the overhead power line is realized by utilizing the computing capability and the visual representation capability of the geographic information system.
Description
technical field [0001] The invention relates to the technical field of power transmission lines, in particular to an intelligent line selection method for power transmission lines based on GIS multi-objective dynamic programming technology. Background technique [0002] With the deepening of my country's power industry system reform, the system and method of power engineering project management are also constantly being explored and improved. However, due to the short period of power system reform, the construction management mode and method of power engineering projects are still very backward in many aspects. . Especially for power transmission and transformation projects, the application of scientific project management ideas is still in the exploratory stage, so introducing the idea of optimal management into scientific management of power transmission and transformation projects will become the focus of power system research . [0003] In the existing line selection ...
