Description

Technical Field

[0001] This invention belongs to the field of substation design, and particularly relates to a three-dimensional parametric design method and system for substations based on GIM. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In China's power grid construction projects, the application of 3D digital technology for engineering design and digital handover has begun to be widely promoted. As the State Grid Corporation of China (SGCC) continues to raise its requirements for 3D design, its efforts to promote 3D design are also intensifying.

[0004] The 3D design of the substation was carried out using 3D design software such as Bentley, Bochao, and Jinqu, which are uniformly specified by the State Grid Corporation of China. The main tasks were equipment modeling and overall assembly layout. According to the specifications issued by the State Grid Corporation of China, the electrical 3D modeling method uses basic primitives such as cuboids, cylinders, and cones to assemble models into components, which are then assembled to form electrical equipment. The model creation is relatively complex and involves many types of models. In order to improve the efficiency of 3D design and standardize the format of 3D equipment models, the Infrastructure Department of the State Grid Corporation of China organized the State Grid Economic Research Institute and several provincial design institutes to complete the creation of a general model library, forming commonly used model design templates, which effectively reduced the modeling work of substation 3D models.

[0005] The inventors discovered that currently, the preliminary design phase utilizes a general-purpose model for layout. However, based on accumulated and optimized experience in substation design, this model cannot fully meet the construction requirements of existing substations and requires modification before it can be used. Equipment without a general-purpose model needs to be remodeled. The design model in the construction drawing phase is even more complex. According to State Grid specifications, the modeling in the construction drawings must be consistent with the manufacturer's model components, resulting in lengthy modification times. 3D design only solves the 3D viewing effect and some collision detection issues, failing to play its due role in design output, construction, and operation and maintenance. 3D design requires extensive manual model assembly, and the final assembly does not form a digital logical result, leading to low work efficiency, lack of data retention and verification, and inability to be reused, resulting in significant resource waste. Summary of the Invention

[0006] To address at least one of the technical problems mentioned above, this invention provides a three-dimensional parametric design method and system for substations based on GIM. By analyzing the linking methods of model construction and layout, it enables rapid model building, thereby completing the assembly of the substation entity model and forming a parametric design template.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The first aspect of this invention provides a three-dimensional parametric design method for substations based on GIM, comprising the following steps:

[0009] Determine the logical interface information of each component in the electrical equipment model;

[0010] Based on the logical interface information of each component in the electrical equipment model, the logical relationships between each component are analyzed.

[0011] The logical relationships between the components are verified for compliance. After passing the compliance verification, a parametric modeling template is generated.

[0012] The engineering database is formed by models built using parametric modeling templates and commonly used electrical equipment models;

[0013] The planner designs the substation layout, links it to the engineering database, and generates a three-dimensional layout plan based on the obtained coordinates, orientations, and connection relationships of the equipment and buildings.

[0014] Based on the key parameter data of the 3D layout scheme, solidify the 3D results and generate a parameterized template.

[0015] A second aspect of the present invention provides a GIM-based three-dimensional parametric design system for substations, comprising:

[0016] The interface information determination module is used to determine the logical interface information of each component of the electrical equipment model;

[0017] The parametric modeling module is used to analyze the logical relationships of each component based on the logical interface information of each component in the electrical equipment model; to perform compliance verification on the logical relationships of each component; and to generate a parametric modeling template after passing the compliance verification.

[0018] The 3D layout scheme generation module is used to form an engineering database from models constructed using parametric modeling templates and commonly used electrical equipment models; it plans the substation layout scheme, links it to the engineering database, and generates a 3D layout scheme based on the obtained expressions of equipment and building coordinates, orientations, and connection relationships;

[0019] The parametric template generation module is used to solidify the 3D results and generate parametric templates based on the key parameter data of the 3D layout scheme.

[0020] A third aspect of the present invention provides a computer-readable storage medium.

[0023] A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of a GIM-based three-dimensional parametric design method for substations as described in the first aspect.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention is based on GIM (Geometric Information Modeling) for substation parametric design. By analyzing the linking methods of model construction and layout, it achieves rapid model building, thereby assembling the substation entity model and forming a parametric design template. Based on the key parameter data corresponding to the 3D layout scheme, it automatically retrieves equipment from the engineering database to generate the parametric template. This solves the problem of designers' tedious splicing of geometric elements of equipment models using traditional methods. By inputting parameter data and making fine adjustments, it can achieve a layout of design results that meets various requirements, adding digital logic functionality.

[0026] 2. This invention utilizes parametric template design functionality to generate a 3D digital twin of a substation. This method employs parametric modules to represent key data from the design phase. For project reuse, module data can be directly extracted and modified to create a new project, significantly improving the accuracy of project reuse.

[0027] 3. This invention helps promote 3D forward collaborative design. While 3D substation design has been widely adopted for many years, the promotion of forward design is severely constrained by design efficiency, significantly diminishing the functionality of 3D design. This new method greatly improves the modeling and layout efficiency for designers. 3D modeling and layout are no longer the primary tasks, saving more time for considering the rational planning and layout of substations, truly reflecting the value of designers.

[0034] Terminology Explanation

[0035] GIM model: a unified data model that is feasible, operable, and meets the needs of three-dimensional design for power transmission and transformation projects.

[0036] 3D parametric design of substations: Based on the characteristics of existing 3D substation design, this feature enables automatic model generation and model layout by inputting key parameter data.

[0037] This invention avoids repetitive copying work, enabling rapid 3D modeling and layout, adding digital logic, and creating a 3D digital twin of the substation. It utilizes parametric modeling and layout methods. Parametric modeling assembles geometric models parametrically based on the internal logical relationships of equipment models. Parametric layout uses key design data from the technical solution to automatically parametrically express the relationships between various equipment, ultimately generating a 3D layout. Subsequent modifications can be made by adjusting parameters, greatly improving design efficiency and accuracy. Similar projects can directly use data templates, enhancing the design efficiency of similar projects and positively promoting subsequent forward design.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment provides a three-dimensional parametric design method for substations based on GIM, including the following steps:

[0040] Step 1: Determine the logical interface information of each component of the electrical equipment;

[0041] In step 1, determining the logical interface information of each electrical equipment component includes:

[0042] Components are formed by assembling and splicing basic primitives, and then the components are connected to form electrical equipment of a substation. Connections between all components are formed by splicing geometric primitives, therefore, each component carries corresponding geometric information, attribute information and necessary connection relationship information. Clear division and connection are achieved through confirmation by technical personnel and equipment manufacturers, for example, connection angles between components, expression of safety distances, connection information (the connection mode between components, such as through circular solid, square pipe, oil pipe, etc.) and the like, so as to obtain the logical relationship between all components.

[0043] Step 2: formulating a template, determining the primary and secondary connection sequence of components based on the sizes and dimensions of each component of the electrical equipment, the logical relationships, and the information of connecting elements between each component, while analyzing and adjusting key data parameters of component sizes;

[0044] wherein the primary and secondary connection sequence means that most of the components are connected to one component, and thus the connected component is identified as the primary component.

[0045] Step 3: performing compliance verification on the logical relationships of each component, determining whether the connection between each component is reasonable, determining the compliance of the logical relationships, preliminarily formulating a parametric template, and returning to step 2 for further modification and improvement before performing this step again if requirements are not met, until requirements are met;

[0046] interconnected modification between components can be achieved at the same time; a parametric modeling template is preliminarily formulated, component sizes can be adjusted by inputting parameters, meanwhile, the template matches the logical relationships of each component, reflects the connection relationship between each component and the primary component, and has an interconnected modification function, that is, when the size of one component is changed, other connected components will be correspondingly moved and modified, and a model is automatically generated after inputting required key parameter data.

[0047] specifically, for adjustment of the model, only the size and dimension of the primary component need to be changed, and other corresponding components will be adjusted accordingly; or the primary component remains unchanged, the offset distance, angle parameter or the like of other components are adjusted, and other components and associated parts will be adjusted accordingly;

[0048] for example, a transformer device includes components such as a body, a radiator, a civil engineering interface, an oil conservator, and an outlet bushing, all these components are connected to the body, the body serves as the primary component, the primary component can be selected as a reference point when formulating the parametric modeling template, and parameter adjustment of subsequent components is performed based on positioning of the body for modification.

[0049] Step 4: after the model is generated, verifying the requirement relationship, forming a parametric modeling template for the electrical equipment after requirements are met, and solidifying a three-dimensional modeling arrangement method according to key parameters of the equipment model;

[0050] Step 5: Based on the requirements of the substation, complete the construction of models of structures and buildings, and combine them with the electrical models constructed using parametric templates and common simple electrical equipment models to form an electrical equipment model library. Integrate these models into an engineering database to create the necessary conditions for parametric layout.

[0051] Step 6: Based on the 3D modeling layout method, calculate the layout of equipment and buildings in the substation in advance, plan the substation layout scheme, link the engineering database, and initially form the expression of the coordinates, orientation and connection relationship of electrical equipment and buildings.

[0052] Step 7: Express the coordinates, orientation, and connection relationships of electrical equipment and buildings to form a rough three-dimensional pre-layout plan;

[0053] Step 8: Based on the rough 3D pre-layout plan, sort out the key parameter data of the layout plan, solidify the 3D results, and form a parameterized template.

[0054] In step 8, through the calculation and implementation of the technical solution, the key technical parameters of the solution are selected to facilitate the layout of equipment, buildings and other models, forming a parametric layout module. This module can automatically retrieve equipment from the engineering database. By inputting key technical parameters into this module, the automatic layout and connection of models in the engineering database can be realized.

[0055] Step 8 also includes: returning to step 6 to refine the device coordinates, attitude, and connection relationships, binding the parametric template to the model, and ensuring that the parametric template can accurately read any model information from the engineering database;

[0056] By inputting key data parameters, the system enables the three-dimensional layout of electrical equipment and building models, completes the precise positioning and orientation of each model, and automatically completes connection information such as wire splicing, ensuring the rationality of the model layout and fully reflecting the design scheme.

[0057] The parameters of the equipment layout are fed back to the parametric layout module. This module can fully reflect the key parameter data of the equipment layout plan, effectively express information such as distance, orientation, and height between models, facilitate the viewing of the accuracy of various data, and can verify safety distances and quickly export collision reports. For non-compliant parts of the design, return to step 8 and repeat the above steps until the design meets all the requirements of the specifications.

[0058] Step 9: Solidify the parametric layout method and quickly realize the design scheme in the parametric layout module.
