Method for partitioning power supply areas based on distribution network GIS system

Abstract

The invention discloses a method for partitioning power supply areas based on a distribution network GIS system. According to the method, grids are used as the smallest load blocks; and based on selection of a core grid, load optimized power supply areas are implemented by taking the most uniform load of each power supply area as the target, taking limitation to a power supply radius as a constraint condition and merging and regulating a plurality of adjacent grids. The method has the advantage of being visual to display; the power supply areas are automatically partitioned by calculation according to actual load of power equipment in each grid; space distribution of an power supply load of a power distribution network is objectively and accurately reflected; by optimizing power supply partitioning, a position and a capacity-load ratio of a distribution and transformation device can be properly regulated and optimized, so that spare capacity is reduced; and objective and scientific technical supports are provided for planning and construction of the intra-area power distribution network.

Description

technical field [0001] The invention belongs to the technical field of a method for dividing power supply areas based on a distribution network GIS system. Background technique [0002] GIS system, that is, geographic information system, refers to the main tasks of collecting, storing, managing, retrieving, analyzing and describing the geographical distribution data of spatial objects and their related attributes, and answering user questions with the support of computer software and hardware. technology system. [0003] Based on GIS, the distribution network GIS system provides functions such as intuitive management of distribution network information based on electronic maps, management of related business processes, management of power outage and power transmission, etc., to realize global unified management and information sharing of distribution network information, and ensure distribution network The standardization, accuracy and completeness of the information.

Problems solved by technology

This method has a great subjective influence, and many important factors are not considered, so that the optimal result cannot be obtained, resulting in deviations in planning

In recent years, relevant personnel in the industry have carried out a lot of research and practice on the medium voltage distribution network, but most of them focus on the reconstruction and optimization of the medium voltage network structure, and the division of the power supply area of ​​the medium voltage distribution network has not received enough attention.
