Power network planning and design method based on GIS and BIM

Abstract

The invention provides a power network line planning and design method based on GIS and BIM. The method includes: 1) in a plan stage, the topography and geomorphology of the region where the distribution network construction project is located are model by using the tilt photography technology of the unmanned aerial vehicle (UAV), the real-time model is imported into the GIS platform, the real-time model is provided with the spatial coordinate information, the pole and tower position is arranged in the model, and the optimal route planning of the power network is determined; 2) a BIM model family database of that distribution network is built; 3) in a design phase, equipment material required for the project are selected from the BIM model family library of the distribution network, combined and installed, and corresponding BIM model are placed according to different conditions of the path points, and finally the three-dimensional model of the whole project is obtained. The method introduces the unmanned aerial vehicle, the GIS and the BIM technology to realize the electric network line planning, and converts the traditional two-dimensional design into the three-dimensional visualdesign, so that the design is more intuitive and more accurate.

Description

technical field [0001] The invention relates to the technical field of power distribution network, in particular to a method for planning and designing power grid lines based on GIS and BIM. Background technique [0002] With the deepening of the reform of the national power system, grid intelligence and convenient operation and maintenance are new requirements for the grid in the new era. According to the development trend of the current power grid project, it can be predicted that the future power grid construction will develop in the direction of continuous expansion of scale, more complex structure, stricter requirements for project quality, and more difficult project management. At the same time, power grid engineering projects generally involve many departments, wide professional fields, short construction periods, and tight construction schedules. These problems also increase the difficulty of construction to a certain extent, and this situation will continue in the f...

Problems solved by technology

[0006] At present, the route planning of distribution network projects mainly relies on the on-site positioning of designers and the drawing of project route maps combined with two-dimensional satellite images. Due to the slow update of satellite maps and deviations from the actual coordinates, the route maps cannot accurately reflect the real-time conditions of the project site, resulting in Plans do not match reality

In the post-construction process, when the construction party finds that the construction cannot be carried out according to the original route plan, there will be design changes, and materials will be returned, so that precise investment cannot be realized

In addition, the on-site survey and positioning of personnel requires a large workload, and there are still some areas that personnel cannot enter, so there are blind spots in the planning

[0007] During the design process, the selection of equipment materials is also described in the form of two-dimensional CAD drawings and text. There are many types of materials, so it is easy to cause deviations in the understanding of all parties, resulting in errors in material selection, resulting in design failures. ACCIDENT
