Abstract
The invention provides an automatic avoiding selection method and system for power transmission lines. The method includes the following steps that avoiding data are acquired, and avoiding areas are selected according to the avoiding data; the avoiding areas are classified, and the safe distance between corresponding avoiding areas is determined; a condition pile position path of the lines is specified; an initial pile position is adjusted according to the avoiding areas and the safe distance; all lines meeting avoiding conditions are determined according to a starting point, an ending point and an adjusted pile position; the optimum line is calculated and selected from the lines meeting the avoiding conditions according to the shortest path optimization algorithm. According to the automatic avoiding selection method and system for the power transmission lines, the shortest path optimization algorithm is applied to power transmission line selection, accurate avoiding is carried out in the line selection process through existing data according to avoiding standards, avoiding reasonability is well guaranteed, the smallest length of a line path is obtained, and therefore line selection results are safe, reliable, economical and reasonable.
Description
technical field [0001] The invention relates to the field of power transmission line design, in particular to an automatic avoidance selection method and system for power transmission lines. Background technique [0002] With the improvement of spatial resolution and time resolution of satellite images and aerial images, the design of transmission lines is gradually becoming in-house. [0003] In the design of transmission lines, designers can conveniently combine topographic maps, orthophotos, and digital data collected from the field for preliminary selection of lines, which shortens the design time and saves design costs. But at the same time, the reliability of design results is also facing great challenges. Among them, whether to accurately avoid the special areas stipulated in the code will inevitably become an important factor affecting the design quality, and will have a crucial impact on the cost, safety and applicability of overhead lines. [0004] Conventional t...
