Description

Technical Field

[0001] This invention relates to the field of 3D model construction technology, and in particular to a method and apparatus for constructing and displaying 3D models suitable for substation data operation and maintenance. Background Technology

[0002] With the construction of new power systems, the amount of multi-source, multi-state, and heterogeneous data related to electricity, energy, and the broader environment is growing exponentially. Three-dimensional power grid models are an important carrier connecting the physical and digital worlds. Organically integrating these models with system operation data, power grid management data, environmental and meteorological data to construct digital twins of power grid equipment enables real-time monitoring and management of power equipment across all dimensions. Furthermore, it allows for simulation analysis of power grid operation status based on historical data and three-dimensional spatial information, which is of great significance for building digital power grids and new power systems.

[0003] However, when constructing 3D models for the power industry at present, the ledger information of each substation device is often directly bound to the device model in the 3D model without dividing the area where each device is located or the components of the device into multiple levels. Because the amount of data attached to the same device is too large, it not only makes the readability of the coding of each system and device poor, but also makes it impossible for the established 3D model to display the detailed data of each device in a hierarchical manner and highlight the effective data when monitoring the operation and maintenance of each device. As a result, the established 3D model cannot accurately display or analyze the operation and maintenance data of the device. Summary of the Invention

[0036] The following benefits can be obtained by implementing the present invention:

[0037] This invention provides a method and apparatus for constructing and displaying 3D models suitable for substation data operation and maintenance. The construction method includes: constructing 3D building models corresponding to each building and 3D equipment models corresponding to each equipment based on the building structure information and equipment structure information of each building in the substation; obtaining and encoding each region name in the attribute data of each equipment to obtain several region codes; obtaining the equipment code corresponding to each equipment name based on the region code corresponding to each equipment name; generating the component code corresponding to each component name based on the equipment code corresponding to each component name; associating each component code corresponding to each equipment 3D model with the corresponding operation and maintenance data; and dividing each equipment 3D model into the corresponding building 3D model according to the region name to generate the final substation 3D model.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1 The diagram shown is a flowchart illustrating a three-dimensional model construction method for substation data operation and maintenance according to an embodiment of the present invention. The method includes:

[0046] Step S1: Based on the building structure information of each building in the substation, construct a 3D model of each building; wherein, the building structure information includes: the name of the area where the building is located;

[0047] Step S2: Based on the equipment structure information of each device in the substation, construct the corresponding 3D model of each device;

[0048] Step S3: Obtain the attribute data and operation and maintenance data for each device; wherein, the attribute data includes: device name, name of the region where the device is located, and names of several components;

[0049] Step S4: Encode each region name in each attribute data to obtain several region codes, obtain the device code corresponding to each device name based on the region code corresponding to each device name, and generate the component code corresponding to each component name based on the device code corresponding to each component name.

[0050] Step S5: Associate the component codes corresponding to each equipment 3D model with the corresponding operation and maintenance data, and divide each equipment 3D model into the corresponding building 3D model according to the area name to generate the final substation 3D model.

[0051] For step S1, in a preferred embodiment, the building structure information further includes: shape, size, location, and affiliation with adjacent buildings.

[0052] Therefore, when constructing the 3D model of each building based on the building structure information, the 3D model can be constructed according to the specific parameters and information in the building structure information.

[0053] For step S2, in a preferred embodiment, the equipment structure information includes: shape, size, and the name of the building to which it belongs. When constructing the 3D model of each piece of equipment, the 3D model of the equipment can also be divided into the corresponding 3D model of the building to which it belongs, thus forming the final 3D model of the substation.

[0054] For step S3, in a preferred embodiment, the attribute data includes: device name, the name of the region where the device is located, and several component names; such as Figure 2 As shown, from the perspective of design / infrastructure / operation and maintenance, the three-dimensional model is hierarchically divided according to region-interval-equipment-component. In a preferred embodiment, the present invention can further subdivide the coding of each device according to the interval in the region.

[0055] For step S4, in a preferred embodiment, after encoding each region name in each attribute data to obtain several region codes, the region code corresponding to each device name can be used as a prefix to generate the device code corresponding to each device name.

[0056] Furthermore, when generating the component code corresponding to each component name based on the device code corresponding to each component name, the region code-device code corresponding to the component name is used as a prefix, and then a component name code is generated sequentially for each component.

[0057] In a preferred embodiment, each component name in the attribute data also corresponds to several element names. Therefore, a component code corresponding to each element name can be generated based on the component code corresponding to each element name. It is understood that, as... Figure 3 and Figure 4 The component coding diagram shown shows that the coding of a component name is: region code - device code - component code - component code.

[0058] This invention allows for the unified encoding of all devices within the same region using the same regional code. This ensures that the codes of devices within the same region contain the same regional code, and that the codes of components within the same device contain the same regional code and device code. Furthermore, the codes of elements contain the same regional code, device code, and component code, thus forming a region-device-component-component coding hierarchy. After binding each component code with its corresponding operation and maintenance data at multiple levels, a final 3D substation model is generated. This allows the constructed 3D substation model to hierarchically display the operation and maintenance information of each device within a region, or the operation and maintenance information of each component of a device within a region, based on the region-device-component-component coding hierarchy, improving the readability of each device code. In other words, this invention can refer to existing coding standards to establish a highly readable and comprehensive model coding method, enabling a one-to-one correspondence and mapping between 3D model codes and asset ledger codes.

[0059] For step S5, in a preferred embodiment, when associating the component codes corresponding to the 3D models of each device with the corresponding operation and maintenance data, the component codes in the component codes corresponding to the 3D models of each device can be associated with the corresponding operation and maintenance data to achieve the most granular data association. This allows for a hierarchical display of the detailed data of each device and highlights the effective data in subsequent applications.

[0060] After completing the association of operation and maintenance data, the following is also included:

[0061] For each device's 3D model, the operation and maintenance data bound to the device's 3D model are classified according to data type, data format, data source, detection component name, and data acquisition frequency to generate a data table characterizing the device's components; wherein, the data classification diagram is as follows. Figure 5 As shown.

[0062] Furthermore, based on the area name, the 3D models of each device are divided into the corresponding 3D building models to generate the final 3D model of the substation. The established 3D model can then be used to hierarchically display the operation and maintenance information of each device in a certain area, or the operation and maintenance information of each component of a certain device in a certain area, according to the coding hierarchy of area-device-component-element, so as to accurately display or analyze the operation and maintenance data of the device.

[0063] Specifically, this invention optimizes the interaction method of 3D models, using the 3D model as a carrier to present a visual interactive effect that categorizes and displays various information. When a user clicks on the 3D model of the device, they can view the device's current ledger information, operation and maintenance management information, operational information, real-time video, online monitoring information, and inspection records.

[0064] In a preferred embodiment, the present invention also provides a display method suitable for substation data operation and maintenance, and a substation three-dimensional model constructed in the three-dimensional model construction method suitable for substation data operation and maintenance;

[0065] The method for displaying data for substation operation and maintenance includes:

[0066] In response to the user's selection operation in the simulation display interface corresponding to the three-dimensional model of the substation, the target point selected by the user in the three-dimensional model of the substation is obtained; wherein, the target point includes: a region where a three-dimensional model of a device is located, a three-dimensional model of a device, a component in a three-dimensional model of a device, or a component in a component;

[0067] Based on the code corresponding to the target point, obtain the running data of several physical devices corresponding to the target point during runtime;

[0068] Based on the operational data and the data table corresponding to each physical device, simulation calculations and analyses are performed to obtain the operational analysis results corresponding to the target point; wherein, the operational analysis results include: the operational analysis results of all devices in a region, the operational analysis results of a single device, the operational analysis results of a component, or the operational analysis results of a single element;

[0069] A display interface is generated, and the results of the analysis are displayed on the display interface.

[0070] In this embodiment of the invention, the operation analysis results of a region can be displayed based on the area or device clicked by the user, or the operation analysis results of each component under a device can be displayed, or the operation analysis results of a single element can be displayed in detail. This allows for hierarchical display of detailed data for each device and highlights effective data. It also enables the fusion of 3D models and various types of operation data in the power industry at the simulation layer to obtain twin fault events corresponding to power industry fault events, which can better serve equipment maintenance and fault diagnosis.

[0071] In a preferred embodiment, the operational data includes structured data and unstructured data. The unstructured data includes images / videos, XML, and other unstructured data such as main wiring diagrams, SVG diagrams, JSON data, and HTML data. That is, this invention can establish a database cluster with a hybrid storage mode of structured and unstructured data, add fields for 3D model encoding, and simultaneously establish various relational tables according to data classification, aggregating multi-dimensional data together. Using the hierarchical encoding in the 3D model as a unique identification code, multi-source data of the device can be queried. Since the monitoring data of each subsystem or component reflects the operating status of the main device, this solution can associate all device operational data at the device level.

[0072] In a preferred embodiment, the step of performing simulation calculations and analysis based on the operational data and the data table corresponding to each physical device to obtain the operational analysis results corresponding to the target point includes:

[0073] When the physical device corresponding to the target point is a transformer and the corresponding operating data is temperature operating data, a three-dimensional model of the device corresponding to the transformer is loaded based on physical field simulation software. Finite element analysis is performed on the dielectric parameters of the component materials in the data table corresponding to the three-dimensional model of the device. The temperature field distribution results inside the transformer are generated based on the transformer surface temperature, load and ambient temperature. The temperature field distribution results include the temperature analysis results of each point inside the transformer.

[0074] Specifically, this invention can combine the spatial physical information of a three-dimensional model with real-time operational data to further realize the coupled calculation of three physical fields: circuit, magnetic field, and structural force field of electrical equipment.

[0075] Taking transformer temperature field simulation calculation as an example, the three-dimensional model has a very detailed physical model of the main transformer, including components such as bushings, oil conservator, iron core, windings, and radiators. The three-dimensional model can be imported into multiphysics simulation software such as Fluent / COMSOL / ANSYS, and the dielectric parameters of the component materials can be loaded to perform finite element analysis. With parameters such as transformer surface temperature, load, and ambient temperature as input conditions, the internal temperature field distribution of the transformer can be obtained, and the hot spots inside the transformer can be further located.

[0076] The three-dimensional model of this invention can form a coding hierarchy of region-equipment-component-element during construction. Furthermore, when associating equipment operation data, it can integrate and bind structured and unstructured data, thereby providing an effective data source for power equipment fault simulation. This not only improves the readability of each equipment's coding but also effectively displays the detailed data of each equipment at different levels and highlights effective data, enabling the final simulation three-dimensional model to accurately display or analyze the equipment's operation and maintenance data.
