Transmission line selection method and system

Abstract

The invention discloses a transmission line selection method. The method includes the steps that three-dimensional laser radar is carried by an unmanned aerial vehicle to acquire the data parameters of an area with the line to be selected; the acquired data parameters are subjected to modeling, and numerical model data of the area with the line to be selected is obtained; line optimizing selection is conducted, and final transmission line selection results are obtained. The invention further provides a system for achieving the transmission line selection method. According to the method and the system, carrying of the three-dimensional laser radar with the unmanned aerial vehicle is applied to the line selection field of a transmission line for the first time; data collection of the area with the line to be selected is conducted through carrying of the three-dimensional laser radar with the unmanned aerial vehicle, the collected data is processed, automatic analysis is conducted combined with a multi-objective path optimization model constructed, intelligent selection of the transmission line is achieved finally, the intelligent level of the power transmission line is improved all around, the design efficiency is improved, and power transmission corridors are protected from being illegally infringed; moreover, the method and the system can not only be applied to the field of power grid planning and design, but also be applied to other industries for planning of the optimal path.

Description

technical field [0001] The invention specifically relates to a method and system for selecting a transmission line. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] The line selection of power transmission and transformation projects is an important link in the planning and design of the power grid, and it plays a connecting role in the planning and design of the power grid. There are many factors such as line selection and load distribution of power transmission and transformation projects, power grid status, line corridors, site topography and geology, and urban construction development planning. The steps of traditional line selection methods are usually: topographic data search-indoor route selection- On-site survey...

Problems solved by technology

Due to the poor timeliness of the existing topographic map data, it cannot reflect the geological structure and the current situation of forest coverage areas at the time of design, which brings difficulties to the rough selection of routes;

[0005] 2). The elevation information of the traditional topographic map is single and unintuitive, so that the route design scheme cannot fully consider the difficulties in the actual construction project, and the on-site construction cannot be carried out in an orderly manner, especially in areas with complex and changeable terrain. The impact is more serious. The preliminary design After completion, on-site investigation and design modification are often repeated, which affects work efficiency;

[0006] 3). Designers often have to travel through remote areas with harsh terrain during on-site surveys, and personal safety cannot be guaranteed;

[0007] 4). Due to the limited size of the topographic map, designers can only find the optimal route within a range of about one kilometer along the line, and cannot optimally design the route from a larger area;

[0008] 5). The traditional line selection method cannot perform various functions such as analysis and statistics;

[0009] 6). There are many restrictive factors in the process of transmission line planning, such as construction cost, construction difficulty, and transmission stability. Traditional line selection methods cannot integrate multiple factors into one to comprehensively consider the quality of the line, which affects line selection. Quality, while line selection is time-consuming and inefficient, affecting the progress of the entire project
