| With the development of computer technology,the application of 3S technology and the complexity of line corridor planning considerations,the traditional grid routing technology have faced a great challenge.The study,based on the characteristics of Yunnan Province and the typical performance of the northwest and Sanjiang parallel areas experimental area,using the geographic information system and geographic cellular automata multi-agent integrated intelligent GIS,through the geographical cellular automata thought and Ant colony algorithm,taking into account the environmental factors such as icing,pollution,roads,settlements and rivers that affect the transmission line path,and applying the analytic hierarchy process to determine the weight value of each environmental factor,definites the model and value relationship between the grid construction and the surrounding environment.This paper builds a simulation of the automatic route selection of the grid from the starting point of the experimental area(Tai'an substation)to the end point(Jiantang substation)under the premise of minimizing the cost and maximizing the ecological benefits.The method which selects or plans a reasonable path under certain restrictive conditions provides a new intelligent method for grid planning and optimization.In the course of the study mainly completed the following work:(1)Constructing the evaluation index system of intelligent selection model of UHV transmission line pathThe evaluation index system of UHV transmission path was established by using GIS technology,and the weight value of each influencing factor was obtained by using analytic hierarchy process.Finally,the cost raster map of the experimental area was obtained by using the superposition analysis function.(2)Building the conversion rules of UHV transmission path selection based on cell ant colony algorithmThe two-dimensional and three-dimensional transmission path planning model based on ant colony algorithm is constructed.According to the different characteristics of the algorithm,the cost raster map of the experimental area is processed,and the algorithm model is designed according to the experimental feature.(3)In the ArcGIS platform to achieve the Add-in plug-in of the two-dimensional and three-dimensional ant colony transmission path planning algorithmBased on the two-dimensional and three-dimensional path planning model of the ant colony algorithm,combined mixed programming of MATLAB,C#and ArcGIS,The Add-in plug-in of the two-dimensional and three-dimensional ant colony algorithm based on ant colony algorithm is developed and verified.(4)Comparing and analyzing the results of the two-dimensional and three-dimensional algorithm.Finally,the results of the Add-in plug-in simulation are compared with the field.The results show that the algorithm achieves the expected results in terms of line length and unreasonable crossing of the region.The results of this study show that the proposed method can effectively provide reference and new planning ideas for the optimization of grid routing and hope to provide reference and inspiration to the whole province and related fields. |
