The present work presents the development of a computational tool for the optimization of processes in the elaboration of electromechanical projects of conventional electricity distribution networks. The current process of elaboration of distribution network projects that has significant topographical interferences is slow and depends on software with a technological lag that requires post processing of the data to generate the final project, besides demanding specific technical knowledge and too much elaboration time. This elaboration time, as well as the errors occurred in the post-processing stage, hinder the approval process of the projects in the electric power concessionaires, and delay the connection of final consumers. For modeling the process, the typologies of the terrain where the network path is to be determined through surveys of the topographic data are verified first. Afterwards, mechanical forces and stresses are observed in each type of electromechanical structure, defining the minimum mounting distances in compliance with related technical norms, as well as incident variables such as wind speed and mechanical variations of the conductors during the operation. The modeling of the decision variables is applied a recursive heuristic method with the application of the Hill Climbing optimization method, which sweeps the entire line defined by topography, performing the mechanical evaluations and calculations with the optimization of technical budget criteria, generating uniform solutions and Automated. The tool obtained is developed in Web platform with friendly interface and updated, and can be used through any browser. The software, besides providing the elaboration of the project with embedded normative criteria, can be easily used for project analysis, providing integrated visualization of the planialtimetric profiles through Google Maps, optimizing the process of visual evaluation.
