Embodiment 1

[0033] The transmission line route optimization method in this embodiment follows the method described in the summary of the invention.

[0034] Specifically, the selected test area in this example application is the area spanned by the Chijiu line. First, the area DEM is generated as a cost layer, and then digitized and stored in the database. After that, the line set is initialized. Finally, based on the traditional genetic algorithm and The improved genetic algorithm finds the optimal route, and combines it with OpenLayers for front-end display.

[0035] Compare the route generated by the algorithm with the route that has already been built. Let the route that has been built be scheme 1, the route calculated using the traditional genetic algorithm be scheme 2, and the route calculated based on the improved genetic algorithm be scheme 3. The results are compared for example Table 1 shows.

Abstract

The invention discloses a power transmission line path optimization method and a computer program product. The method comprises the following steps: (1) DEM digitization; (2) a power transmission lineplane model; (3) forming a path initial solution; (4) designing a fitness function; (5) power transmission line optimization genetic operator design; and (6) outputting an optimal path result. The method is based on the improved genetic algorithm, optimal individuals (elite individuals) generated in the evolution process are not subjected to cross pairing and are directly copied to the next generation, it is guaranteed that the optimal individuals are not damaged or lost by cross, variation and selection operation, and the method plays an important role in global convergence of the genetic algorithm. According to the method, the problem that the global optimal path cannot be obtained is solved. Meanwhile, the GeoServer and the OpenLayers are combined, the permission limitation problem when a researcher carries out line optimization on the basis of ArcGIS in the past is solved, and on the premise that the line planning efficiency is improved, the comprehensive cost is saved.

Description

technical field [0001] The invention relates to a transmission line path optimization method and a computer program product, in particular to a transmission line path optimization method based on an improved genetic algorithm and a computer program product, belonging to the technical field of transmission line planning and design. Background technique [0002] In recent years, the demand for electricity has been increasing all over the country. The transmission line is the link between the power plant, the substation and the user, and is an important element that constitutes the transmission network and the distribution network. Based on this, the efficient and scientific planning of the transmission line is of great significance. [0003] The core of power grid transmission line planning and design is the selection of transmission line route scheme, which belongs to the category of route optimization. Early transmission line planning mainly relied on manual labor, which had...
