Embodiment 1

[0047] like figure 1 As shown, a digital twin power grid system based on a three-dimensional map, the system includes:

[0048] A power grid map drawing unit, configured to acquire node data and line data of the power grid system, and generate a three-dimensional map of the power grid based on the acquired node data and line data;

[0049] The power grid map layering unit is configured to divide the three-dimensional map of the power grid based on the preset number of layered layers to obtain multiple layered maps;

[0050] A layered map feature extraction unit, configured to perform feature extraction on each layered map to obtain layered map features;

[0051] The layered map mapping unit is configured to map and connect the layered map with the power grid, and at the same time map and connect the layered map features with the power grid;

[0052] The control unit is configured to send a control command to the layered map or layered map feature, and the control command is ...

Embodiment 2

[0055] On the basis of the previous embodiment, the method for generating a three-dimensional grid unit by the grid mapping unit includes: acquiring the three-dimensional coordinate data of each grid node, and acquiring the three-dimensional coordinate data of the starting point and the end point of each line; The three-dimensional coordinate data of the node is compared with the three-dimensional coordinate data of the starting point or end point of each line, and the grid nodes whose three-dimensional coordinate data are completely consistent are connected to the starting point or end point of each line until the completion of all grid nodes. Comparison.

[0056] refer to figure 2 and image 3 , figure 2 and image 3 The process of the present invention for extracting features of a layered map is shown in Fig. 1. A layered map often has a large number of nodes and lines. If processing is performed directly, the processing efficiency will be reduced, and the feature ext...

Embodiment 3

[0058] On the basis of the previous embodiment, the power grid map layering unit performs the following steps when segmenting the three-dimensional power grid map:

[0059] Step A1: set the division direction; the set division direction must satisfy: the mean value of the included angle with the directions of all lines of the power grid does not exceed the set threshold;

[0060] Step A2: Set the segmentation thickness; the set segmentation thickness must meet: under the set segmentation thickness, the nodes of the grid included in each layered map obtained after segmentation should exceed the set threshold;

[0061] Step A3: Segment the three-dimensional map of the power grid according to the set dividing direction and the set dividing thickness to obtain multiple layered maps.

Abstract

The invention relates to the technical field of power grids, in particular to a digital twin power grid system and method based on a three-dimensional map. The system includes: a grid map drawing unit configured to acquire node data and line data of the grid system, and generate a three-dimensional grid map based on the acquired node data and line data; a grid map layering unit configured to The number of layered layers divides the three-dimensional map of the power grid to obtain multiple layered maps; the layered map feature extraction unit is configured to perform feature extraction on each layered map to obtain layered map features. It builds a virtual map of the power grid to realize digital twin-based control of the power grid. At the same time, when constructing a virtual map, it uses layering and feature extraction to control the power grid, which improves the efficiency of power grid control.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to a digital twin power grid system and method based on a three-dimensional map. Background technique [0002] Digital twin is a multi-disciplinary, multi-physical, multi-scale, multi-probability simulation process that makes full use of physical model, sensor update, operation history and other data to complete the mapping in virtual space, thereby reflecting the full life cycle of the corresponding physical equipment process. A digital twin is a concept beyond reality that can be viewed as a digital mapping system of one or more important, interdependent equipment systems. [0003] The proponent of the digital twin conceptual model proposed its three-dimensional structure in 2011, including the physical model of the physical space and the virtual model of the virtual space, and the data and information interaction between them. The three-dimensional structural mo...
