Single-line digital modeling method for man-machine interaction type power grid

Abstract

The invention provides a single-line digital modeling method for a man-machine interaction type power grid. The method comprises the following steps: S1, analyze and preprocess power grid data which comprises pole point data, pole line data and equipment data, and carry out data structure reconstruction on the pole line data of the grid data; S2, carry out checking on the continuity, the repeatability and the integrity of the power grid data; S3, carry out single-line graph digital modeling on the checked power grid data by utilizing a graph depth priority search algorithm; step S4, when an operator carries out the reliability analysis of the power supply of the power grid or drawing errors exists in the single-line, the operator can edit and modify the single-line graph; S5, store the modified power grid data in the grid data table. The method adopts a man-machine interaction power grid single-line drawing, through which it is convenient for the operator to use, and also it is convenient for the designers to analyze the reliability of grid power supply.

Description

technical field [0001] The invention relates to the field of grid power supply, in particular to the technical fields of computer graphics and electric power engineering, and in particular to a human-computer interactive grid single-line digital modeling method. Background technique [0002] Existing power grid data is stored separately in excel form data and dwg drawings without correlation. The reliability analysis of line power supply using Excel table data is not visualized, and the reliability of the analysis results is poor; the dwg drawings obtained by traditional modeling lack parametric data, and power supply reliability analysis cannot be performed. At the same time, with the development of the power system, the power system has become an increasingly complex and huge system. The application of visual graphics technology will help the research and operation management of the power system. Due to the complex structure of the distribution network structure, a large ...

[0004] 1. For the topological structure of the power grid, it is only suitable for drawing simple radial feeder systems for reliability assessment, not for analysis of mesh topological structures; new power market policies such as changes in competition management systems, separation of plants and networks, transmission and distribution Electrical separation adds new forms to the graphic elements of the power system, and the drawing form of the graphic elements, the generation method and device of the one-line diagram must be adjusted accordingly;

[0005] 2. In terms of visual drawing and human-computer interaction, the drawing function of the graphic drawing module needs to be further improved and improved;

[0006] 3. There is no data verification function, and the modification of new graphics elements and the storage of grid data in new forms cannot be realized

Although this patent also adopts the automatic conversion of AutoCAD graphics into dispatching one-line diagrams and system diagrams used by dispatchers in distribution automation systems, this method adopts the method of hierarchical conversion and hierarchical display in large and medium-sized distribution network automation systems , choose to convert and display the different information of the background layer, device layer, and device label layer, and at the same time automatically generate the topological relationship of the graph row; that is, the technical solution adopted is not the same as this patent
