GIS-based power grid planning project full-process closed-loop control method and system

Abstract

The invention discloses a GIS-based power grid planning project full-process closed-loop control method and system. The method includes performing diagnosis analysis of the power grid present situation of a setting area; determining the important degree and solution scheme of the problems of lines or equipment and performing power grid planning of the fault lines or equipment; performing power grid planning information data acquisition and pretreatment; performing power grid planning project scientific reviewing and power grid planning project graph drawing at the power grid GIS platform based on the power grid GIS existing racks according to the acquired data; and evaluating the technology feasibility of the power grid planning project content. Through the combination with the power grid GIS platform, the basic data fusion degree of intelligent distribution network monitoring and geography information is improved, and the function of GIS system planning is improved, and the full-process online management of project propose, project database management, scientific reviewing, GIS graph drawing, and after-project evaluation of middle-low voltage projects.

Description

technical field [0001] The invention relates to the technical field of power grid planning process management and control, in particular to a GIS-based closed-loop control method and system for the whole process of power grid planning projects. Background technique [0002] Power grid planning is a complex and arduous system engineering, which has the characteristics of large scale, wide fields, and many participating departments. Power grid planning and design is a complex system engineering, with large data volume, many uncertain factors, and wide And the characteristics of fast update and change. [0003] The existing grid planning project management has the following problems: [0004] (1) The planning project involves a large amount of data, and manual statistics and summarization lead to unsmooth processes, and it is difficult to analyze and apply scattered data. The distribution network planning data covers the province's power grid 110kV, 35kV, 10kV and other new c...

AI Technical Summary

Problems solved by technology

[0005] (2) For a long time, the power grid has only met the load demand as the goal, the goal is single, and there is a lack of planning guidance for the long-term target grid structure, and there are phenomena of repeated construction and large-scale demolition and construction

The five links of planning preparation, project early stage, investment plan, project implementation, and project post-evaluation are not closely connected, which is not conducive to the promotion of planning implementation

[0006] (3) Lack of planning project management tool software, establish a power grid planning project management database,
