[0027] Embodiment 1

[0028] Figure 1 A flowchart of a method for generating a digital twin based on electrical topology is provided for the first embodiment of the present application. The embodiment of the present application can be applied to the construction of a digital twin for a substation. The method can be executed by a digital twin generating device based on electrical topology. The digital twin generating device based on electrical topology can be implemented in the form of hardware and / or software. The digital twin generating device based on electrical topology can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0029] S110, obtaining electrical topology information of the substation.

[0030] The electrical topology information includes relative coordinate information of electrical devices and connection relationship information between electrical devices; the relative coordinate information of electrical devices reflects the relative position between at least two electrical devices, for example, electrical device A is located at a certain position of electrical device B. In a specific example, the relative coordinate information of the electrical devices can be reflected in a spatial coordinate system. The connection relationship information between electrical devices reflects the path of the connection line between the electrical devices and the type of the connection line.

[0031] Specifically, in a specific example, the electrical equipment information is read from the electrical topology diagram of the substation, and then the connection relationship information between the electrical equipment is read. In another feasible solution, the electrical network topology node data is read from the PMS (power management system), the equipment data of each node of the substation electrical topology is obtained, and then the connection relationship information between the electrical equipment is read.

[0032] S120, updating the scanning coordinates of the electrical equipment in the initial digital twin based on the relative coordinate information of the electrical equipment to obtain an updated digital twin.

[0033] Among them, the initial digital twin includes electrical equipment in the substation. The position of each electrical equipment is determined according to the scanning coordinates. The scanning coordinates reflect the coordinates of the electrical equipment obtained by scanning. The scanning coordinates can be obtained by calculating and recording the coordinate positions of the scanning points in real time through a scanner or measuring instrument through its built-in sensors and positioning system; due to the problem of low accuracy of the scanning coordinates in the initial digital twin, the scanning coordinates of the electrical equipment in the initial digital twin can be updated based on the relative coordinate information of the electrical equipment to obtain a more accurate updated digital twin of the position coordinates of each electrical equipment.

[0034] Specifically, in the initial digital twin, the scanning coordinates of at least two electrical devices are obtained; if the scanning coordinates of at least two electrical devices do not match the relative coordinate information of the at least two electrical devices, the scanning coordinates of the electrical devices in the initial digital twin are adjusted based on the relative coordinate information of the electrical devices to obtain an updated digital twin with updated coordinates.

[0035] Exemplarily, taking two electrical devices as an example, the position of one electrical device relative to the other electrical device can be calculated based on the scanning coordinates of the two electrical devices. If there is a difference between the position and the relative coordinate information of the two electrical devices, the scanning coordinates of the electrical devices in the initial digital twin are adjusted based on the relative coordinate information of the electrical devices.

[0036] S130, generating a line model between the electrical devices in the updated digital twin based on the connection relationship information between the electrical devices to obtain a final digital twin.

[0037] The connection relationship information between the electrical devices reflects the path of the connection line between the electrical devices and the type of the connection line.

[0038] Specifically, in updating the digital twin, the electrical equipment is traversed, and if the currently traversed electrical equipment is connected to other electrical equipment, the path of the connection line and the type of the connection line are determined, and the model of the support body that needs to be generated on the path of the connection line is determined according to the type of the connection line, and after the support body is generated, the line model is generated on the support body. The support body can be an object such as a pole tower used to support the line.

[0039] The technical solution of the embodiment of the present application includes: obtaining the electrical topology information of the substation; the electrical topology information includes the relative coordinate information of the electrical equipment and the connection relationship information between the electrical equipment; updating the scanning coordinates of the electrical equipment in the initial digital twin based on the relative coordinate information of the electrical equipment to obtain an updated digital twin; generating the line model between the electrical equipment in the updated digital twin based on the connection relationship information between the electrical equipment to obtain the final digital twin. This technical solution generates the final digital twin in the initial digital twin based on the topology information of the electrical equipment, which accelerates the generation speed of the digital twin and improves the generation quality of the digital twin.

[0044] In an embodiment of the present application, optionally, obtaining electrical topology information of the substation includes: reading the nodes and branches of the electrical network topology; determining the coordinates of the node as the coordinate information of the electrical equipment; determining the relative coordinate information of the electrical equipment corresponding to the at least two nodes based on the coordinate information of at least two nodes connected to the branch; and determining the connection relationship information between the electrical equipment based on the nodes connected to the branch.

[0045] Specifically, in a feasible solution, nodes and branches are read from the electrical network topology information, electrical equipment information is determined based on the node information, and the coordinates of the node are determined as the coordinate information of the electrical equipment. If there is a branch connected between the nodes, the electrical equipment corresponding to the node is the electrical equipment with a connection relationship. If the branch is connected to at least two nodes, the coordinates of the connected nodes are subtracted to obtain the relative coordinate information of the electrical equipment corresponding to the at least two nodes.

[0046] S220, updating the scanning coordinates of the electrical equipment in the initial digital twin based on the relative coordinate information of the electrical equipment to obtain an updated digital twin.

[0047] In an embodiment of the present application, optionally, the relative coordinate information of the electrical device includes: relative position data of the first electrical device with respect to the second electrical device; accordingly, the scanning coordinates of the electrical device in the initial digital twin are updated based on the relative coordinate information of the electrical device to obtain an updated digital twin, including: obtaining the position coordinate data of the first electrical device in the initial digital twin compared to the second electrical device; if the position coordinate data does not match the relative position data, adjusting the position of the first electrical device in the initial digital twin based on the relative position data to obtain an updated digital twin.

[0048] Exemplarily, taking two electrical devices as an example, the two electrical devices are the first electrical device and the second electrical device, and the relative coordinate information of the electrical devices is: the relative position data of the first electrical device with respect to the second electrical device (for example, the first electrical device is located 3 units in the positive direction of the x-axis of the second electrical device, and 2 units in the positive direction of the y-axis). The position coordinate data of the first electrical device and the position coordinate data of the second electrical device in the initial digital twin can be obtained, and the two position coordinate data are subtracted to obtain the position coordinate data of the first electrical device compared to the second electrical device; if the position coordinate data is inconsistent with the relative position data, the position of the first electrical device in the initial digital twin is adjusted based on the relative position data to obtain an updated digital twin.

[0053] Exemplarily, read the electrical topology constraint file in the substation, and obtain the constraint of the node based on the electrical equipment ID. The constraint mainly includes: island, no power supply, connectivity, inconsistent voltage level under the same feeder, lack of belonging interval of the equipment in the station, null value constraint, duplication constraint, inclusion constraint, non-inclusion constraint, threshold constraint, time series data anomaly constraint, Chinese character compliance constraint, ledger address integrity constraint, non-compliant character mixing constraint and floating point compliance constraint and other constraint rules. Query the substation digital twin data model according to the node equipment ID, and request the organizational structure, component information, bounding box, attributes and other information of the model corresponding to the ID through the index file, data file and attribute file. Carry out the spatial layout of the substation digital twin, first obtain the precise positioning coordinate value (x2, y2, z2) of the substation, and calculate the precise absolute coordinate value (x1+x2, y1+y2, z1+z2) of the equipment according to the relative coordinate offset of the equipment. The 3D model data of the corresponding node equipment is loaded on the 3D visualization engine, and the rendered 3D model is moved to the calculated absolute coordinate value of the equipment. At the same time, the corresponding equipment attribute information (including equipment ledger, inspection records, real-time operation status and other data) is superimposed. At the same time, according to the equipment electrical topology constraint rules, the equipment that does not meet the safety interval and line height is automatically fine-tuned, and the corresponding coordinate values ​​are increased or decreased to meet the constraint rules. The equipment models of different voltage levels and the energized status are marked with colors to realize the spatial layout and rapid construction of the digital twin of the substation based on the electrical topology, and support the linkage and interaction between the substation equipment and the topological network.

[0054] The electrical topology constraint rule base of the station equipment mainly includes two types: business rules and data rules. The business rules include: island, no power supply, connectivity, inconsistent voltage levels under the same feeder, lack of bays for station equipment, etc.; the data rules include: null value constraints, duplication constraints, inclusion constraints, non-inclusion constraints, threshold constraints, time series data anomaly constraints, Chinese character compliance constraints, ledger address integrity constraints, non-compliant character mixing constraints, and floating point compliance constraints.

[0055] S230: Determine a type of a support body for supporting a line according to a line type in a connection relationship between the electrical devices.

[0056] Specifically, if the line type is an overhead line, the supporting body type is a pole tower, etc.; if the line type is a busbar, the supporting body type is a busbar bridge, etc.; if the line type is a cable, the supporting body type is a cable bridge, etc. Further, after determining the supporting body type of the supporting line, the supporting body model is determined based on the supporting body type.
