Problems solved by technology
Distribution network operation indicators are important indicators for evaluating the reliability of distribution network power supply. At present, most of the analysis of distribution network operation indicators are multi-dimensional statistics classified by region and industry. Although there are many types of statistics, the analysis granularity is relatively coarse Mine, lacking more detailed features

Embodiment Construction
[0025] The following is based on Figure 1 to Figure 4 A further description of the specific implementation of the present invention is made: this distribution network operation index processing method based on subdivided geographical regions uses the grid analysis idea, and maps it to the pre-divided grid unit according to the GPS latitude and longitude information to which the distribution transformer belongs In the grid unit, the power consumption characteristics of the distribution transformer, the load characteristics of the distribution transformer, and the load information of the distribution transformer are analyzed, from the traditional passive discovery of problems to active discovery of problems, from single management to supervision, and the analysis granularity More refined.
[0026] Taking Jiangsu Province as an example, the distribution network operation index processing method based on subdivided geographic regions includes the following steps:

The present invention discloses a distribution network operation indicator processing method based on a segmented geographic region. The method comprises the following steps: dividing a geographic region into multiple relatively independent grid cells without overlapping power supply ranges; mapping all distribution transformers into corresponding grid cells; by means of a similarity algorithm, dividing types of the distribution transformers in the grid cells into pure household distribution transformers, pure commercial distribution transformers or mixed distribution transformers; calculating load information of the distribution transformers in the grid cells, and calculating a maximal load rate, a minimal load rate and an average load rate of the distribution transformers in the grid cells during different periods of time, and determining power utility characteristics of the distribution transformers in the grid cells; calculating a load indicator of the distribution transformer in each grid cell; and displaying the power utility characteristic and load indicator of the distribution transformer in each grid cell in the form of a map, so as to determine a distribution network operation indicator of the grid cell. According to the method provided by the present invention, the grid analysis idea is used to analyze the power utility characteristics, load characteristics and load information of the distribution transformers in the grid cells, and the analysis granularity is more refined.
Description
technical field [0001] The invention belongs to the technical field of electric power intelligent application, and in particular relates to a distribution network operation index processing method based on subdivided geographic areas. Background technique [0002] Grid management is an emerging management model based on global information interactive computing in recent years. Its main purpose is to use the grid as the smallest unit to realize effective resource sharing and collaboration of the grid. [0003] As an important part of the smart grid, the distribution network is directly oriented to users and is a key link to ensure the quality of power supply, improve the efficiency of power grid operation, and provide high-quality services. Distribution network operation indicators are important indicators for evaluating the reliability of distribution network power supply. At present, most of the analysis of distribution network operation indicators are multi-dimensional sta...
