specific example

[0039] Specific example: evaluation and analysis of engineering adaptability in a certain area

[0040] Carry out regional engineering adaptability analysis on the proposed area, analyze and divide the variability of terrain, geology, groundwater and other conditions in the area, and establish the slope ratio distribution map, slime layer distribution map, and surface water system density of the proposed line area map, swamp density distribution map, frost heave area density distribution map, thermal caster development density distribution map and other line selection factor maps, according to figure 1 Scientifically analyze the process and get rid of the uncertainty, randomness and unscientificity brought by the artificial line selection in the past.

[0041] The invention provides a line selection method for power transmission and transformation projects, which solves the problems of large uncertainty and low efficiency in line selection of power transmission and transformat...

Abstract

The invention relates to the field of electric power system planning, in particular to a line selection method for a transmission and transformation project. The line selection method for the transmission and transformation project comprises the following steps: 1) determining an expected construction range of the transmission and transformation project, and determining N investigation areas in the construction range; 2) conducting investigation on each of the investigation areas, and determining measurement values of M line selection factors in the investigation areas; 3) determining Y leading factors from the M line selection factors, and determining the appropriate values of the investigation areas according to the leading factors; 4) selecting X investigation areas from the N investigation areas as the electric transmission and transformation line passing areas. The line selection method for the transmission and transformation project, disclosed by the invention, solves the problems that the current transmission and transformation project line is high in selection uncertainty, and low in efficiency, and greatly reduces the cost for operation and maintenance by quantifying the geological factors in the line selection project through multi-factor superposition.

Description

technical field [0001] The invention relates to the field of power system planning, in particular to a line selection method for power transmission and transformation projects. Background technique [0002] The power system mainly includes generators of power plants, step-up substations, transmission lines, step-down substations, power distribution systems and users, among which transmission lines are an important part of the entire system. [0003] At present, in the research stage of power transmission and transformation project construction, the selection of line paths and substation locations mainly depends on the experience of on-site personnel, which puts forward very high requirements for the comprehensive quality of personnel. Due to different considerations, the results of different personnel selection The difference may be very large, resulting in the uncertainty of the route selection results, so that in the later stage of construction drawing design, it often res...
