[0026] like Figure 1-2 As shown, the present invention provides an editing and controlling method for the operation of electric power equipment based on digital twin technology, including constructing a twin digital model and a visual three-dimensional model according to an electric power system, and associating and mapping the visual three-dimensional model and the twin digital model, wherein the electric power system includes a plurality of electric physical devices;

[0027] The twin digital model is edited by using a blueprint editor, the twin digital model is displayed in the blueprint editor in a graphical manner, and the graphic is associated and mapped with the corresponding twin digital model;

[0028] On this basis, the control method includes changing the graphic state corresponding to the power physical device from closed to open in the blueprint editor when it is necessary to control the power physical device to disconnect, then the state of the power physical device in the twin digital model changes from closed to open, and the state of the power physical device in the visualized three-dimensional model changes from closed to open.

[0029] like Figure 1-2 As shown, the blueprint editor creates a function node library based on the LiteGraph front-end open source framework, and visualizes it with a graph with twin digital model information, and associates and maps the twin digital model with the corresponding image.

[0030] like Figure 1-2 As shown, the function node library includes general categories and twin categories; the general categories include basic operations, logic control, event processing, and mathematical operations; the twin categories include batch execution of twin actions, batch setting of twin states, execution of twin actions, setting of twin states, acquisition of twin states, acquisition of twins, and positioning of twins;

[0031] like Figure 1-2 As shown, the basic operations include string, Boolean value, define variable, update variable, merge object, debugger; the logic control includes multiple branches, or, and, non-switch action, equal, comparison; the event processing includes browser window event, timer, scene preparation completion, mouse event, key event; the mathematical operation includes addition, subtraction, multiplication, and division.

[0032] like Figure 1-2 As shown, the twin acquisition is to be associated with the twin digital model through the twin ID and name, and displayed in a graphical form, which can be used as input data for setting the twin state and executing the twin action; the twin action acquisition is used to obtain the state data of the associated twin digital model, which is used as input data for setting the twin state; the twin state setting is used to control the change of the state attribute value of the graphic; the twin action execution is used to control the graphic to execute a specified action.

[0033] like Figure 1-2 As shown, the method for constructing the twin digital model includes:

[0034] Classify the power physical equipment in the power system and define the attributes of each classified power physical equipment, including ledger information, operation information, action information and status information;

[0035] Construct a twin digital model corresponding to each classification, and the power physical equipment of the same classification adopts the same twin digital model;

[0036] Associate and map the twin digital model with the corresponding power physical equipment in the power system.

[0037] like Figure 1-2 As shown, the classification of power physical equipment includes primary classification, secondary classification and tertiary classification. The primary classification includes substations and converter stations, the secondary classification includes transformers, circuit breakers, busbars, and disconnectors, and the tertiary classification includes equipment parts, oil storage cabinets, windings, and iron cores.

[0038] like Figure 1-2 As shown, the ledger information includes name, model, manufacturer, rated voltage, rated current, and power station; the operation information includes opening and closing status, active power, reactive power, item A voltage, item A current; the action information includes closing action and opening action; and the status information includes disconnection status and connection status.

[0039] The twin digital model is a digital model of the physical equipment of the real power system, which aims to achieve real-time monitoring, analysis and optimization of the power system. By synchronizing with the real-time data of the physical equipment, the twin digital model can reflect the status and behavior of the equipment, provide accurate operation information, support decision-making and fault prediction. The construction of the twin digital model includes the definition of ledger information, operation information, action information and status information.

[0040] The present invention aims to control the twin digital model through visual programming. First, the power physical equipment needs to be classified to facilitate the management and construction of the twin digital model. Secondly, the framework of the twin digital model is quickly constructed according to the classification. The twin digital model is associated and mapped with the actual power physical equipment according to the classification, so that the twin digital model and the power physical equipment information can interact in real time. Finally, the twin digital model can be edited and controlled through the blueprint editor.

[0041] Regarding the classification of electrical physical equipment, the details are as follows:

[0042] The equipment types of the State Grid power system are classified according to the classification. A corresponding twin digital model is constructed for each classification. The classification is divided according to the tree structure, with the first-level classification being the system level, the second-level classification being the equipment level, and the third-level equipment being the component level.

[0043] The first-level classification is mainly system level, such as substation and converter station.

[0044] The second level classification is the equipment level, such as transformers, circuit breakers, busbars, and disconnectors.

[0045] The third level classification is the component level, such as the transformer casing, oil conservator, winding, core and other components.

[0046] After analysis and statistics, the ledger information and dynamic information corresponding to the twin digital model under each category are established respectively.

[0047] Ledger information: records the static properties of the twin digital model, that is, the static inherent attribute information corresponding to the real physical device, such as name, category, geographic location, equipment model, specifications, production date, etc.

[0048] Operation information: records the dynamic properties of the twin digital model, that is, the operation data corresponding to the actual physical equipment, such as voltage, current, power, temperature and other real-time operation data.

[0049] Action information: records the operational actions that the twin digital model can perform, that is, corresponds to the actions that the real physical device can perform, such as starting, shutting down, adjusting, etc.

[0050] Status information: records the current status of the twin digital model, which corresponds to the status of the actual physical device, such as running, stopped, faulty, etc.

[0051] Regarding 3D model mapping, the details are as follows:

[0052] The digital twin system has a corresponding three-dimensional model that truly reflects the appearance and other visual information of the physical object. The three-dimensional model is stored using the file system middleware and a three-dimensional model library management service is established. The classification of the three-dimensional model is consistent with the twin classification, and the model attributes of the three-dimensional model are defined at the same time. Because there are different models of equipment under the same classification, the appearance and functions are different. According to the type and model attribute information of the physical device, it is associated with the corresponding three-dimensional model, and the association mapping between the twin digital model and the three-dimensional model is established.

[0053] Regarding attribute relationship mapping, the details are as follows:

[0054] Establish an interactive relationship between operation information, action information, status information, and three-dimensional models, and use the twin as the collection point to allow virtual digital objects to interact with physical devices, mainly including associating the three-dimensional model's own animation with the twin digital model's operation information, and associating the attributes of the operation information with the physical device's action and status.

[0055] The animation effect of the three-dimensional model itself is associated and mapped with the operating information attributes of the twin digital model. For example, when the state attribute of the twin digital model is associated with the opening and closing animation of the three-dimensional model, when the state attribute value of the twin digital model becomes closed, the corresponding three-dimensional model executes the opening rotation animation.

[0056] The operating information attributes of the twin digital model are associated and mapped with the action or state control instructions of the power physical equipment. For example, when the voltage attribute of the twin digital model changes, the "adjust voltage" operation instruction is sent to the corresponding physical device, and the state attribute is updated to "voltage regulating".

[0057] The details of the association between the twin digital models are as follows:

[0058] Create a twin digital model based on the above classification information to ensure that each twin digital model uniquely corresponds to the real physical device and supports adding unique attributes for maintenance. Before creating a twin digital model, you need to select the category to which the twin belongs. After selecting the category, the twin digital model is associated and mapped with the actual power physical device, automatically synchronizing all attribute information of the power physical device.

[0059] The relationship between the twin digital models is maintained using the Neo4j graph database, such as the connection, control, and dependency relationships between the twin digital models. Neo4j's graph data model can efficiently store and query complex relational data and supports flexible query languages, which are suitable for managing the relationship between devices in the power system, such as querying all lines connected to a transformer, or querying all devices controlled by a circuit breaker.

[0060] The Eclipse Ditto open source framework is used as the basis for implementing the management service of the twin digital model. The framework provides functions such as data synchronization, event management and remote calling, and supports real-time interaction with power physical equipment.

[0061] Regarding the Blueprint Editor, the details are as follows:

[0062] The Blueprint Editor is based on the LiteGraph front-end open source framework for functional implementation, and combines the Babylon Editor desktop application to classify and plan the control nodes of the three-dimensional scene operation flow and implement expansion. It provides a richer user interface and interactive functions, aiming to enable users to easily create, edit and manage the twin digital model of the power system and its interactive logic through an intuitive graphical interface.

[0063] (1) An intuitive graphical human-computer interaction interface, including a toolbar, an operation node panel, an editing canvas, and a detailed property panel. Users can drag nodes from the "operation node panel" to the canvas, connect each operation node with a connection line to edit it, and synchronize the edited changes to the corresponding twin digital model.

[0064] (2) The editor provides a variety of predefined operation nodes, each of which is a program encapsulation for operating 3D scenes, data interaction, and event triggering. Classification is based on application scenarios. The classification level is 2, the first level is application scenario classification, and the second level is the included nodes. The specific classification and included node definitions are as follows:

[0083] Positioning twin: It is an action type node. In a 3D scene, it can find the associated 3D model through a given twin object and display the 3D model in the center of the visible window.

[0084] The blueprint editor can also build visual 3D scenes, including park scenes and map scenes. The park is implemented using the BabylonJS framework, which is a small-scale detailed display, such as the substation scene.

When used, it is dragged into the editing area as an independent node, receives the upstream process through the input interface, and flows into the next node through the output interface.

[0105] (6) 3D rendering engine planning

[0106] The 3D twin scene rendering runtime engine is implemented based on the open source framework BabylonJS. It is responsible for rendering 3D scenes and parsing and executing operation processes. The running steps include:

[0107] Process execution: According to the arranged operation logic process, the scene executes each node operation in the order of the workflow.

[0108] Data synchronization: During the process execution, the engine will synchronize the twin attributes, 3D model animation and physical device status in real time to ensure that the three remain consistent.

[0109] The present invention is further described below by taking a circuit breaker as an example.

[0110] 1. Obtain and count the classification of power physical equipment. This embodiment uses the primary equipment in the station for statistical classification. There are many classifications. This embodiment mainly lists the classifications as follows: transformers, circuit breakers, disconnectors, load switches, lightning arresters, voltage transformers, current transformers, and busbars.

[0111] 2. Select the circuit breaker classification to define the twin attribute information, and obtain the attribute information through statistical analysis as follows:

[0112] Inventory information, such as name, model, manufacturer, rated voltage, rated current, and power station.

[0113] Operation information: such as opening and closing status, active power, reactive power, item A voltage, item A current.

[0114] Action information: such as opening and closing.

[0115] Status information: such as open and closed status.

[0116] 3. According to the model, select the 3D model that is consistent with the appearance of the physical device and associate it, indicating that the circuit breakers of the same model are rendered using this model instance.

[0117] 4. Define the classification actions of the circuit breaker twins, which mainly include opening and closing actions.

[0118] 5. Define the classification status of the circuit breaker twin, which mainly includes the two state changes of open and closed.

[0119] 6. Associate the classification attributes of the circuit breaker twin with the action and state, so that the circuit breaker twin can execute the corresponding action or change the state when a certain attribute value changes. For example, when the attribute value of the circuit breaker twin's opening and closing state changes from "closed" to "open", the state of the power physical device also changes and remains consistent with the circuit breaker twin. Conversely, when the attribute of the power physical device changes, the corresponding attribute value of the circuit breaker twin also changes.

[0120] 7. The state and action of the circuit breaker twin are mapped to the three-dimensional model. When the circuit breaker twin's opening and closing state value changes, the three-dimensional model can execute the corresponding action and keep synchronization with the circuit breaker twin's attribute value and the state of the power physical equipment.

[0122] 9. After the information configuration of the twin digital model is completed, open the blueprint editor for editing and control, as follows:

[0123] Drag the "Get Twin" blueprint node from the node library of the blueprint editor to the canvas, and select the twin associated with the node as the circuit breaker twin digital model.

[0125] Drag in the "Execute Twin Action" and "Set Twin State" nodes.

[0126] Drag in the Twin Event node and connect the event output connection point to the event input connection point of the Perform Twin Action node.

[0127] Connect the output connection point of the "Get Twin" node with the input connection point of the "Twin Digital Model" of the "Twin Action" with a line, and the "Twin Action" node will automatically add the action output connection point list.

[0128] Select the "Close" connection point of the "Twin Action" node and connect it to the "Action" connection point of the "Execute Twin Action" node.

[0129] Connect the output event connection point of the "Perform Twin Action" node to the input event connection point of the "Set Twin State" node.

[0130] Connect the output connection point of the "Get Twin" node with the "Twin Digital Model" input connection point of the "Twin State" node with a line, and the "Twin State" node will automatically add the state output connection point list.

[0131] Select the "Join" connection point of the "Twin State" node and connect it to the "State" connection point of the "Set Twin State" node with a line.

[0132] 10. Edit the circuit breaker status to the closed state through the blueprint editor, then the twin digital model will be synchronized to the closed state, and send a closing command to the power physical equipment, and the physical equipment will perform the closing operation.
