Embodiment 1

[0017]Please refer tofigure 1 Embodiments of the present invention one as: a component of a substation and a location of the selection, which can be applied to the active distribution network planning, including the following steps:

[0018]S1: Several unit plots and power grids from small to large.

[0019]Specifically, according to the region corresponding to the county-level administrative district, the planning area is determined, that is, the county (district) is divided into the jurisdiction, and the planning area is obtained; gridization division of the planning area, get more than one power supply Grid; divide each power grid, resulting in more than one unit plot.

[0020]S2: Load prediction of the planning area to obtain load forecast results. The load prediction includes a long-term load prediction and a near medium-term load prediction.

[0021]Among them, the vision load prediction is specifically:

[0022]S211: The functional land index information in each unit plot is collected, and ...

Embodiment 2

[0068]This embodiment is a specific implementation scenario of the above embodiment.

[0069]I. Grid planning business process

[0070]In response to the characteristics of online job mode, follow the problem-oriented and target-oriented effective combination, establish a pattern of hierarchical coordinating operations on the GIS chart, set the "Planning Version-Planning Program - Planning Project" three-layer management, implementing the region The planning version consolidation, different planning plan selection, planning project unified management, can effectively strengthen the planning and conversion of each level, improve the overall, coherence, economy of grid planning. The initial sort of business processes is as follows:

[0071]1, reference setting

[0072]The planned benchmark time is clear, generally as a time cross section on December 31, or as a reference picture (closer to the current situation, the closer time is closer, the grid topology is closer to the actual), determined Per...

Embodiment 3

[0225]This embodiment is a computer readable storage medium corresponding to the above-described embodiment, which stores a computer program, which is implemented when executed by the processor:

[0226]Sequentially divide unit plots and power grids from small to large.

[0227]Load prediction of the planning area to obtain load forecasting results;

[0228]According to the load prediction result, the settlement and location of the substation are performed.

[0229]Further, the preset planning area divides unit blocks, power supply units, and power grids from small to large; specifically:

[0230]According to the region corresponding to the county-level administrative district, the planning area is determined;

[0231]Grid dividing the planning area to get more than one power grid;

[0232]Each power grid is divided, and more than one unit plot is obtained.

[0233]Further, the planning area is predicted, and the load prediction is specifically:

[0234]For the planning area, the planning area is predicted to...

Abstract

The invention discloses a constant volume and site selection method of a transformer substation and a storage medium. The method comprises the steps: sequentially dividing a preset planning area intounit plots, power supply units and power supply grids from small to large; carrying out load prediction on the planning area to obtain a load prediction result; and performing constant volume and siteselection of the transformer substation according to the load prediction result. According to the invention, data support and scientific basis can be provided for power grid planning decision making,precise planning is realized, related technicians are assisted in making decisions, and the purpose of improving the working efficiency is achieved.

Description

Technical field[0001]The present invention relates to the technical field of active distribution network, and more particularly to a component of a substation and a location method, a storage medium.Background technique[0002]At present, power grid development has not yet applied geographic information technology design related grid grid structure models, and the grid models designed by other business departments are not entirely applicable to development majors. In order to open the data standards of each business department, the barriers such as lack of lack of data, how to meet the design of the relevant grid model to meet the distribution network planning, and the demand for the display of relevant indicators is one of the key points and difficulties.[0003]Grid geographic information resources are often only served as a backgroundboard, and there is no association with grid resources. In the grid analysis, how to integrate second-source related information for geographic resource...
