[0041] In order to make the objectives, technical solutions, and advantages of this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not used to limit this application.

[0042] High-voltage power equipment (such as converter transformers) plays a key role in high-voltage electrical systems, and its performance directly affects the safe and stable operation of the power system. To achieve the stable operation of the power system, it is necessary to quickly and accurately model high-voltage power equipment for purposes such as simulation calculations. However, given the large volume and complex structure of high-voltage power equipment, directly modeling not only has a high working difficulty but also is difficult to achieve the required accuracy. Moreover, after modeling, device assembly is required. However, using traditional assembly techniques, such as manual dragging, not only has complex operations but also low accuracy, which may ultimately lead to poor assembly efficiency and other related problems.

[0043] This application provides a method for constructing a geometric model of high-voltage power equipment, which can perform hierarchical design on the geometric model of high-voltage power equipment such as converter transformers. Through hierarchical modeling of the equipment, the speed and accuracy of model establishment can be effectively improved; and it can quickly assemble high-voltage power equipment under different devices and various forms, such as fixed reference plane type, axial array type, and reference plane offset type, which can reduce the difficulty of device assembly and effectively shorten the device assembly time.

[0044] In an exemplary embodiment, as Figure 1 shown, a method for constructing a geometric model of high-voltage power equipment is provided. In this embodiment, taking the application of this method to a terminal as an example, it can be understood that this method can also be applied to a server and can also be applied to a system including a terminal and a server and be realized through the interaction between the terminal and the server. In this embodiment, the method includes the following steps 101 to step 104. Among them:

[0045] Step 101, determine the hierarchical structure of the high-voltage power equipment based on the internal and external device data and different part characteristics of the high-voltage power equipment; each layer in the hierarchical structure contains different device components.

[0046] As an example, the internal and external device data may include the collected internal device data of the device (obtained from CAD drawings) and the external device data of the device (obtained from point cloud measurement).

[0047] In practical applications, according to the collected internal and external device data of the high-voltage power equipment, through hierarchical modeling analysis of the model, hierarchical modeling can be performed on the hierarchical structure of the high-voltage power equipment; taking the converter transformer as an example, as Figure 2As shown, according to the characteristics of different parts of the converter transformer, each equipment component can be divided into three hierarchical structures: the overall layer, the component layer, and the detail layer, and each layer contains different equipment components.

[0048] Exemplarily, the hierarchical structure can include the overall layer at the macroscopic level, the component layer at the level of equipment sub-components, and the detail layer at the microscopic level. For example, taking the converter transformer as an example, the overall layer can include data such as the overall shape and size of the converter transformer and its related devices to reflect the macroscopic characteristics of the equipment; the component layer can include each sub-component that makes up the converter transformer, including but not limited to the iron core, winding, bushing, and insulation structure; the detail layer can include equipment detail information such as the wire layout of the winding and the thickness of the insulation layer.

[0049] Step 102: Perform hierarchical modeling according to the hierarchical structure of the high-voltage power equipment to obtain model hierarchical information; the model hierarchical information includes the modeling parameters of the equipment components at each level.

[0050] In a specific implementation, as Figure 2 shown, Creo modeling software can be used to perform hierarchical modeling on each equipment component after refining the hierarchical structure, obtain the modeling parameters of the equipment components at each level, and can obtain information such as the reference plane and reference coordinate axes of each equipment component, and then obtain the model hierarchical information.

[0051] Step 103: Compare the model hierarchical information with the physical information of the high-voltage power equipment to obtain a model verification result.

[0052] After obtaining the model hierarchical information, the model hierarchical information can be compared with the physical information of the high-voltage power equipment. As Figure 2 shown, the accuracy verification of the model can be realized by comparing the model with the physical object, that is, the model verification result can be used to represent whether the model accuracy verification is passed.

[0053] Step 104: In the case where the model verification result is verified to pass, according to the predefined assembly relationship, use the modeling parameters of the equipment components at each level to perform model assembly to obtain the geometric model of the high-voltage power equipment.

[0054] Among them, the geometric model can be used to support the simulation calculation of the operation of the high-voltage power equipment. For example, the geometric model can contain information such as the spatial positions, relative relationships, and geometric shapes of all devices in the high-voltage power equipment.

[0055] In an example, in the case where the model verification result is verified to pass, as Figure 2 shown, by predefining the assembly relationship in the program and using the modeling parameters of the equipment components at each level to perform model assembly, the geometric model of the high-voltage power equipment can be obtained, so as to achieve the effect of rapid model assembly.

[0056] Specifically, according to the secondary development function of Creo software, rapid assembly of each equipment component in hierarchical modeling can be carried out; for example, the coordinate axes or coordinate plane names of each equipment component are obtained, and rapid positioning and rapid assembly are achieved through constraint functions. Therefore, through the hierarchical design and rapid assembly of the geometric model of high-voltage power equipment, it is helpful to improve the calculation efficiency and real-time performance during model simulation.

[0057] In the above method for constructing the geometric model of high-voltage power equipment, by determining the hierarchical structure of high-voltage power equipment based on the internal and external equipment data and different part characteristics of high-voltage power equipment, and then performing hierarchical modeling according to the hierarchical structure of high-voltage power equipment to obtain model hierarchical information, comparing the model hierarchical information with the physical information of high-voltage power equipment to obtain a model verification result, and then, in the case where the model verification result is passed, according to the predefined assembly relationship, using the modeling parameters of the equipment components at each level for model assembly to obtain the geometric model of high-voltage power equipment, realizing the hierarchical design and rapid assembly of the geometric model of high-voltage power equipment, and effectively improving the speed and accuracy of geometric model construction.

[0058] In an exemplary embodiment, the performing hierarchical modeling according to the hierarchical structure of the high-voltage power equipment to obtain model hierarchical information may include the following steps:

[0059] Modeling each of the equipment components included in each of the levels respectively to obtain the modeling parameters of each of the equipment components; the hierarchical structure includes an overall layer at the macroscopic level, a component layer at the equipment sub-component level, and a detail layer at the microscopic level; according to the reference information and the modeling parameters of each of the equipment components, the model hierarchical information is obtained; the reference information includes the reference plane and reference coordinate axes of the corresponding equipment component.

[0060] In an alternative embodiment, Creo / TOOLKIT software can be used to perform secondary development on Creo modeling software to achieve component hierarchical modeling after refining the hierarchical structure. Exemplarily, Creo software can be developed using C language or C++ language, and then after setting connection statements, hierarchical modeling of the equipment components of high-voltage power equipment can be carried out, and information such as the reference plane and reference coordinate axes of each equipment component can be obtained.

[0061] For example, according to the specific components of the three-layer structure of the overall layer, component layer, and detail layer obtained through analysis, hierarchical modeling can be carried out in combination with Creo software and its development tools. Taking a converter transformer as an example, such as Figure 3As shown in the figure, in the overall layer part, the fuel tank shell can be modeled, which can include the modeling of parts such as the shell, oil conservator, riser, cooler, etc.; in the component layer part, the iron core, winding, bushing, and insulation structure can be modeled, specifically including parts such as the core column, yoke, winding, etc.; in the detail layer part, the detail information such as the number of winding turns, cross-sectional area of the coil, and number of iron core layers can be modeled.

[0062] In this embodiment, by modeling each equipment component included in each layer respectively, the modeling parameters of each equipment component are obtained, and then based on the reference information and modeling parameters of each equipment component, the model layer information is obtained, which can realize multi-level and high-precision modeling of the equipment structure.

[0063] In an exemplary embodiment, comparing the model layer information with the physical information of the high-voltage power equipment to obtain the model verification result may include the following steps:

[0064] Determine the comparison error between the model layer information and the physical information of the high-voltage power equipment; if the comparison error does not exceed the preset error threshold, confirm that the model verification result is verified; in the case where the comparison error exceeds the preset error threshold, use an error optimization algorithm to reduce the comparison error to not exceed the preset error threshold, and confirm that the model verification result is verified.

[0065] In practical applications, by comparing and analyzing the model after hierarchical modeling with the physical object, the accuracy verification of the model can be realized; optionally, the error (i.e., the comparison error) of the key parts in the high-voltage power equipment can be set not to exceed 4% (i.e., the preset error threshold). For example, the length, width, and height of the model shell compared with the physical object have an error not exceeding 4%. If the error is too large, optimization algorithms such as PSO and GA (i.e., the error optimization algorithm) can be used to reduce the error until the error of all components does not exceed 4%, and then confirm that the accuracy verification is passed.

[0066] In this embodiment, by determining the comparison error between the model layer information and the physical information of the high-voltage power equipment, if the comparison error does not exceed the preset error threshold, confirm that the model verification result is verified; in the case where the comparison error exceeds the preset error threshold, use an error optimization algorithm to reduce the comparison error to not exceed the preset error threshold, and confirm that the model verification result is verified, which can ensure the accuracy of the model verification result and help improve the precision and reliability of the high-voltage power equipment modeling.

[0067] In an exemplary embodiment, it may further include the following steps:

[0068] Information is marked for each of the said levels and each of the device components in the level to obtain record data for identification in maintenance processing; the record data includes hierarchical design information, a device component list, model assembly information, and maintenance instruction information.

[0069] In one example, by making detailed documentation for each level and its device components, such as including design concepts, component lists, assembly instructions, and maintenance guides, it can ensure that all levels and their components have clear marking information for easy identification in subsequent maintenance and upgrades.

[0070] In this embodiment, by marking information for each level and each device component in the level to obtain record data for identification in maintenance processing, it can contribute to efficient identification and management during device maintenance processing.

[0071] In an exemplary embodiment, the model assembly using the modeling parameters of the device components at each of the said levels according to the predefined assembly relationship may include the following steps:

[0072] Using a modeling tool, set the reference coordinate system, coordinate axes, and reference planes through constraint functions, and import the device components at each of the levels in the high-voltage power equipment into the assembly interface of the modeling tool; assemble the imported device components at each of the levels in the high-voltage power equipment according to the model assembly requirements.

[0073] In practical applications, based on the secondary development tool of the modeling software Creo (i.e., the modeling tool), by predefining the assembly relationship in the program, rapid model assembly can be achieved, and dynamic adjustment of dimensions can be supported through parametric design.

[0074] Specifically, the rapid assembly function can be implemented using the secondary development tool of Creo software, which requires an equipped environment and basic framework; an entry function can be set, which can be used for subsequent programs to place all data in the entry function. For example, taking the user_initialize() function as the entry function, the extern "C" int user_initialize() function can be used to call the entry function from Creo software, and the extern "C" void user_terminate() function has been used to end the call.

[0075] Before assembly, the following method can be used to set the reference coordinate system in the entry function:

[0076] ProError CreateDefaultCsys(

[0077] ProMdl model,

[0078] ProName feature_name, / / Coordinate system name

[0079] ProGeomitem *csys);

[0080] The reference coordinate axes can be set in the entry function in the following way:

[0081] ProError CreateAxis(

[0082] ProMdl model,

[0083] ProName feature_name, / / Axis name

[0084] ProGeomitem **reference_all, / / Reference object

[0085] ProGeomitem *Axis_Geom);

[0086] The reference plane can be set in the entry function in the following way:

[0087] ProError CreateDefaultDatumPlane(

[0088] ProMdl model,

[0089] ProName feature_name, / / Plane name

[0090] ProGeomitem *DTM_x,

[0091] ProDtmplnConstrType pro_dtm_pln_constr_type); / / Constraint type

[0092] After setting the reference coordinate system, axes, and plane, they can be imported in the sketch interface (i.e., the assembly interface) through methods such as extrusion, scanning, array, envelope, chamfering, etc., or directly import the basic components of each layer of the converter transformer; furthermore, the components to be assembled can be quickly assembled according to specific requirements by means of fixed reference plane assembly, axial array assembly, and reference plane offset assembly.

[0093] In this embodiment, by using a modeling tool, a reference coordinate system, coordinate axes, and reference planes are set through constraint functions. In the assembly interface of the modeling tool, equipment components at each level in the high-voltage power equipment are imported. Then, according to the model assembly requirements, the equipment components at each level in the imported high-voltage power equipment are assembled, which can achieve efficient and accurate equipment modeling and assembly, and improve the modeling efficiency and accuracy.

[0094] In an exemplary embodiment, the step of assembling the imported equipment components at each level in the high-voltage power equipment according to the model assembly requirements may include the following steps:

[0095] Assemble the imported equipment components at each level in the high-voltage power equipment according to the fixed reference plane assembly method, axial array assembly method, and reference plane offset assembly method.

[0096] In a specific implementation, for the fixed reference plane assembly, the ProModelitemByNameInit() function can be used to obtain the names of three reference planes and control the coincidence of three corresponding reference planes. The constraint type is PRO_ASM_ALIGN. The fixed reference plane assembly can be represented in the following way:

[0097] ProError UserAssembleByDatums_00(

[0098] ProAssembly asm_model, / / Main body

[0099] ProSolid comp_model); / / Mate

[0100] In an example, for the axial array assembly, the ProModelitemByNameInit() function can be used to obtain the names of two reference planes and a central axis, control the coincidence of one corresponding reference plane and the corresponding central axis. The constraint type is PRO_ASM_ALIGN, and the remaining corresponding reference planes form an angle. The constraint type is PRO_ASM_ALIGN_NODEP_ANGLE. The axial array assembly can be represented in the following way:

[0101] ProError UserAssembleByDatums_01(

[0102] ProAssembly asm_model, / / Main body

[0103] ProSolid comp_model, / / Mate

[0104] double offset_value); / / Deflection angle

[0105] In another example, for the assembly with datum plane offset, the ProModelitemByNameInit() function can be used to obtain three datum planes, control two corresponding datum planes to coincide with the corresponding central axes, the constraint type is PRO_ASM_ALIGN, and the remaining corresponding datum planes form a displacement, the constraint type is PRO_ASM_ALIGN_OFF. The assembly with datum plane offset can be expressed as follows:

[0106] ProError UserAssembleByDatums_02(

[0107] ProAssembly asm_model, / / Main body

[0108] ProSolid comp_model, / / Mate

[0109] double offset_value); / / Offset distance

[0110] In this embodiment, by assembling the equipment components at each level in the imported high-voltage power equipment according to the fixed datum plane assembly method, the axial array assembly method, and the datum plane offset assembly method, the assembly of the multi-level equipment components in the high-voltage power equipment can be completed efficiently and accurately, improving the modeling accuracy and efficiency.

[0111] In an exemplary embodiment, as Figure 4 shown, a flowchart of another method for constructing a geometric model of a high-voltage power equipment is provided. In this embodiment, the method includes the following steps:

[0112] In step 401, based on the internal and external device data of the high-voltage power equipment and the characteristics of different parts, determine the hierarchical structure of the high-voltage power equipment. In step 402, model each device component included in each layer respectively to obtain the modeling parameters of each device component, and obtain the model layering information according to the reference information and modeling parameters of each device component. In step 403, determine the comparison error between the model layering information and the physical information of the high-voltage power equipment. In step 404, if the comparison error does not exceed the preset error threshold, confirm that the model verification result is passed. In step 405, in the case where the comparison error exceeds the preset error threshold, use an error optimization algorithm to reduce the comparison error to not exceed the preset error threshold, and confirm that the model verification result is passed. In step 406, in the case where the model verification result is passed, use a modeling tool to set the reference coordinate system, coordinate axes, and reference plane through constraint functions, and import the device components of each layer in the high-voltage power equipment into the assembly interface of the modeling tool. In step 407, assemble the device components of each layer in the imported high-voltage power equipment according to the fixed reference plane assembly method, axial array assembly method, and reference plane offset assembly method to obtain the geometric model of the high-voltage power equipment.

[0113] It should be noted that the specific limitations of the above steps can be referred to the specific limitations of a method for constructing a geometric model of a high-voltage power equipment described above, and will not be elaborated here.

[0114] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown in sequence according to the arrows, these steps do not necessarily need to be executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps does not have a strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages, and these steps or stages do not necessarily need to be executed at the same time, but can be executed at different times, and the execution order of these steps or stages does not necessarily need to be sequential, but can be executed alternately or alternately with at least a part of other steps or steps or stages in other steps.
