Description

Technical Field

[0001] This invention relates to the field of engineering design technology, and more specifically, to a method, apparatus, equipment, and medium for multi-stage continuous design of engineering models. Background Technology

[0002] Hydropower and pumped storage projects are characterized by their large scale, long construction period, involvement of multiple disciplines, and clearly defined design phases. Their engineering design is typically divided into planning, pre-feasibility study, feasibility study, bidding design, and detailed construction phases. Figure 5 The depth requirements for design deliverables vary significantly across different stages. For example, the early stage focuses on the overall layout of the hub and the comparison of different schemes, with lower requirements for the geometric accuracy of the model; while the later stage of detailed design requires complete structural details to support the implementation of construction.

[0003] BIM technology, as a three-dimensional digital modeling and collaborative management technology, is widely used in engineering fields such as hydropower and pumped storage. It can realize three-dimensional visualization modeling, parametric design and multi-disciplinary collaborative design of key engineering structures, covering the entire design stage such as planning, feasibility study, bidding and construction details. It can intuitively present the overall layout and structural form of the project, support engineering scheme simulation, design optimization and digital delivery, and promote the development of water conservancy and hydropower engineering design towards digitalization and integration.

[0004] However, when existing BIM technology is applied to this field, there are core problems such as model stage fragmentation, parameter transfer discontinuity, and model granularity rigidity. Specifically, different design stages require repeated modeling, and the early conceptual model cannot directly serve the later detailed design; the key parameters determined in the early stage cannot be automatically transferred to the later model, and manual re-entry is prone to introducing errors; the level of model detail is fixed in the early stage of design, and if the early model is too simple, it will not be able to expand the details later, while if it is too precise, it will affect the efficiency of the early scheme comparison and selection process, and cannot meet the design needs of the entire project life cycle.

The model granularity upgrade instruction is obtained by manually triggering it with an interface button, automatically triggering it based on the design stage identifier, or automatically switching it based on the model display ratio. The detailed design data is associated with the conceptual design model in the form of a sub-architecture.

[0012] Optionally, the multi-stage continuous design method for the engineering model further includes: The target engineering model with standardized characteristics is stored in a standardized container, and the target engineering model with non-standardized characteristics is stored in a non-standardized container.

[0017] The beneficial effects of the multi-stage continuous design method, apparatus, equipment, and medium for engineering models of the present invention are: Obtaining conceptual design data for the target project enables precise extraction of core design basis, avoiding parameter transmission gaps caused by manual extraction deviations of early design parameters. Constructing a conceptual design model based on this data creates a foundational model adapted to the early design needs of the project, preventing inappropriate granularity settings from impacting design efficiency. Adding detailed design data and building detailed design models based on the conceptual model allows for extension of detailed designs without the need for independent model reconstruction, effectively addressing the issues of fragmented models and repetitive modeling required at different design stages in existing technologies. Binding the conceptual design model and detailed design models and establishing a hierarchical mapping between them creates a target project model that can be flexibly invoked at different design stages. This enables the linked transmission of parameters between the two models, completely eliminating potential parameter transmission gaps, and allows the model to adapt to design requirements at different stages, overcoming the technical shortcomings of rigid model granularity and ensuring the continuity of multi-stage project design.

[0024] like Figure 1 As shown in the figure, an embodiment of the present invention provides a multi-stage continuous design method for engineering models, comprising: Obtain conceptual design data for the target project.

[0025] Specifically, the target project can be the key engineering structure of a hydropower or pumped storage project. Conceptual design data is divided into two categories: conceptual design features and control parameters. Conceptual design features specifically include the building's positioning axis, excavation volume, occupied space, outline boundary, and coordinates of key control points. Control parameters specifically include geometric shape / section type, external dimensions, azimuth, elevation, and topological connections. Data acquisition relies on the feature parameter extraction module of the engineering digital design platform. Data collection and organization can be completed through automatic parsing of design requirements, manual input of benchmark information, and matching of survey data. Furthermore, automatic import interfaces for engineering survey data, 3D terrain data matching and extraction, and reuse of historical engineering conceptual design data can be used to replace manual extraction of conceptual design data. This embodiment can accurately extract core control elements from the early design phase, eliminate redundant information, and provide standardized and parameterizable basic data for subsequent modeling, ensuring the uniformity and traceability of design data.

[0026] Based on the conceptual design data, a conceptual design model is constructed.

[0027] Specifically, the acquired conceptual design data is imported into a 3D digital design platform to complete parametric modeling. Control parameters from the conceptual design data serve as driving variables, supporting two model update modes: geometric scaling and topological shape modification. Topological shape modification can be achieved by modifying parameters to convert structural forms such as straight dam axis turning lines / curves, single tunnel bifurcation into multiple branches, and side-type intakes to bank-type tower-type intakes. The final generated conceptual design model is a lightweight geometric model with outline geometry and excavation volume envelope. The modeling employs a parametric-driven algorithm, updating the model geometry and topological shape in real time by modifying the driving variable values. Alternatively, visual sketch modeling, template-based rapid modeling, and synchronous finite element mesh generation can be used to replace purely parametric modeling. This embodiment can construct a lightweight and easily adjustable preliminary design model, balancing the efficiency of scheme comparison and the flexibility of layout optimization, avoiding system lag caused by detailed preliminary modeling, and meeting the needs of early-stage project layout and multi-scheme comparison.

[0028] Based on the conceptual design model, detailed design data is added to construct a detailed design model.

[0029] Specifically, based on the conceptual design model, detailed design data is loaded and the model is expanded. The detailed design data includes three categories: sub-product components, additive features, and subtractive features. Sub-product components are standardized parts that can be independently defined and nested, covering common components and standard equipment such as beams, columns, corbels, motors, valves, expansion joints, gates, and hoists. Additive features include additive geometric features such as bosses, stretching, rotation, and sweeping, while subtractive features include subtractive geometric features such as grooves, openings, cutting, and chamfering. Detailed design data is added in a one-time pre-set manner, and can be directly called upon for subsequent component reuse without repeated addition. For example, modeling can use a sub-product nesting algorithm and an additive / subtractive feature Boolean operation algorithm to overlay detailed geometric features onto the conceptual model carrier; modular detail splicing, automatic generation of parametric details, and drag-and-drop addition of components can also be used instead of manual pre-set addition. This embodiment can complete the refined structural supplementation based on the conceptual model, forming a detailed model adapted to later-stage detailed design, retaining the core control logic while improving the detailed structure, meeting the refined design requirements of the feasibility study, bidding, and construction detail drawing stages.

[0030] Bind the conceptual design model and the detailed design model, and establish a hierarchical association mapping between the conceptual design model and the detailed design model to construct a target engineering model. The target engineering model is used to call the conceptual design model and / or the detailed design model at different design stages.

[0031] Specifically, conceptual design models and detailed design models are categorized into the same design object type, and binding is achieved using a database resource mapping table. The two types of models are grouped into the same engineering object resource entry for binding. Hierarchical association mapping establishes the binding relationship between key control points of the conceptual model and construction features of the detailed model, ensuring that the associated features of the detailed model are automatically reconstructed and updated when the parameters of the conceptual model are modified. The constructed target engineering model is a growable, multi-stage design component. The conceptual design model is called in the early stages, and the detailed design model is called automatically / manually in the later stages. Sub-object components can also be nested to achieve hierarchical expansion and calling. This embodiment breaks down the model barriers between design stages, achieving integrated encapsulation and linked updates of the two types of models. The target engineering model can dynamically grow with the design stage, with core parameters passed seamlessly, balancing early-stage efficiency and later-stage accuracy. It enables continuous multi-stage engineering design, while supporting component reuse and multi-disciplinary collaboration, improving design standardization and knowledge reuse rates.

[0032] In this embodiment, acquiring conceptual design data of the target project enables accurate extraction of the core design basis of the project, avoiding the parameter transmission gap problem caused by the deviation of manual extraction of design parameters in the early stage. Based on the conceptual design data, a conceptual design model is constructed, which can form a basic model that adapts to the early design needs of the project, avoiding the problem of improper granularity setting of the early model affecting design efficiency. Based on the conceptual design model, detailed design data is added and a detailed design model is constructed. The detailed design is extended from the conceptual model as the base, without the need to rebuild the detailed model independently, effectively solving the problem of model fragmentation and repeated modeling in the existing technology at different design stages. Binding the conceptual design model and the detailed design model and establishing a hierarchical association mapping between the two, a target project model that can be flexibly called at different design stages is constructed. This not only realizes the linkage and transmission of parameters between the two models, completely eliminating the hidden danger of parameter transmission gap, but also allows the model to adapt to the design needs of different stages, overcoming the technical defects of fixed model granularity and ensuring the continuity of multi-stage design of the project.

[0033] Optionally, the step of binding the conceptual design model and the detailed design model, and establishing a hierarchical association mapping between the conceptual design model and the detailed design model to construct the target engineering model includes: The conceptual design model and the detailed design model are bound together using a resource mapping table; Based on the association mechanism, a binding relationship is established between the key control points in the conceptual design model and the corresponding construction features in the detailed design model. The association mechanism includes at least one of the following: a release mechanism, an external reference mechanism, or an EKL mechanism.

[0034] Specifically, firstly, a resource mapping table is created in the database of the engineering digital design system. The conceptual design model and the detailed design model are grouped under the resource entries of the same engineering object type. The binding of the two types of models is completed by matching the table fields, so that they belong to the same design object module and form an integrated model carrier. Then, based on the selected association mechanism, the linkage binding of parameters and geometry is established. For example, the core control elements such as the positioning axis, key control point coordinates, and shape feature dimensions in the conceptual design model can be extracted as key control points. Then, the corresponding structural features such as gate slots, pressure steel pipe elbows, and branch pipe cones in the detailed design model are matched. The positioning dimensions of the structural features are converted from fixed constants to coordinates or derived parameters that are directly linked to the key control points of the conceptual design model through formulas or reference expressions. The basic association binding is achieved by relying on the publishing mechanism or external reference mechanism to ensure that the association features of the detailed design model can be automatically reconstructed or updated when the parameters of the conceptual design model change. For complex association scenarios such as automatically generating new points after the control point offset and angle association, the precise association mapping is completed by writing EKL rules and embedding logical judgments or conditional statements. Finally, a target engineering model with hierarchical association and parameter linkage is constructed. For example, database-related field binding and model-level label binding can be used instead of resource mapping table binding, and parameter linking formulas and design script linkage can be used instead of publishing mechanisms, external reference mechanisms, or EKL mechanisms to achieve association binding. This embodiment achieves standardized binding of two types of models through resource mapping tables, ensuring unified model ownership, convenient calling and reuse, and establishing a hierarchical mapping relationship that adapts to all scenarios based on multiple association mechanisms. It completely opens up the parameter transmission channel between conceptual design and detailed design, avoids human error in manual parameter entry, and achieves automatic linkage update of detailed models without delay when the conceptual model is adjusted. It ensures the rationality of the model's geometric logic and the consistency of design data, and provides stable association support for subsequent model granularity upgrades, component reuse, and multi-stage continuous design of engineering. Among them, the engineering digital design system refers to a system equipped with a multi-stage continuous design method for engineering models.

[0035] Optionally, obtaining the conceptual design data of the target project includes: Based on the sub-item project division criteria, the target project is broken down and classified to obtain independent design objects; Based on the preliminary design requirements, extract the conceptual design data of the independent design object.

[0036] Specifically, based on the standards for dividing hydropower and pumped storage projects into sub-projects, the key structures of the target project are broken down into independent design units such as the upper reservoir inlet / outlet, gate well, gatehouse, pressure regulating well, transition section, tunnel section, and pressure steel pipe. These units are then categorized and organized according to the structural type and functional attributes of the project, clarifying the design boundaries and scope of each independent design object. Furthermore, based on the preliminary design requirements of the project planning and pre-feasibility studies, core conceptual design data is extracted for each independent design object. Conceptual design features include the building's positioning axis, excavation volume, occupied space, outline boundary, and coordinates of key control points. Control parameters include geometric shape / section type, external dimensions, azimuth, elevation, and topological connections, completing the collection and organization of comprehensive conceptual design data. Additionally, automatic splitting and classification using the engineering BIM model and batch division of independent design objects based on the design ledger can replace manual splitting and classification. Intelligent parameter extraction algorithms and historical project conceptual design data matching and extraction can replace manual on-demand extraction. This embodiment achieves standardized decomposition and classification of target engineering design units, accurately identifies the core data extraction objects in the early design stage, ensures the relevance, completeness and standardization of conceptual design data extraction, and provides a clear unit foundation and standard data support for the subsequent construction of conceptual design models.

[0037] Optionally, constructing a conceptual design model based on the conceptual design data includes: The conceptual design data is linked to the control points of the initial conceptual model using characteristic expressions to obtain the conceptual design model.

[0038] Specifically, the basic framework of the initial conceptual model of the target project is first built, and the key control points of the model are identified as parameter-driven nodes. Then, through feature expressions, the extracted conceptual design data, including the coordinates of key control points, external feature dimensions, azimuth, elevation, and topological connections, are directly linked and bound to the control points of the initial conceptual model. This ensures that even with significant changes in the conceptual design, the construction feature positioning and detailed dimensions remain reasonable without geometrical errors. Using feature expressions as the medium for parameter transmission and driving, the conceptual design data becomes the core driving variable of the initial conceptual model, resulting in a parameterizable conceptual design model. This model supports scaling and adjustment of geometric dimensions and can also change the topological shape through parameter modification, including transforming a straight dam axis into a polygonal or curved shape, a single tunnel bifurcates into multiple branches, and a side intake into a bank tower intake. Furthermore, parameter association formulas and design script links can be used to replace feature expressions to link data and control points, and templated control point matching and visual parameter binding can be used to replace direct linking. This embodiment establishes a linkage channel between conceptual design data and model control points through feature expressions, enabling real-time parameterized driving of the model while taking into account the ability to adjust dimensions and transform topology, thus meeting the needs of rapid scheme comparison and flexible layout optimization in the early design stage.

[0039] Optionally, the multi-stage continuous design method for the engineering model further includes: In the early design phase, the conceptual design model is adjusted by driving parameters; In the later design stage, based on the model granularity upgrade instruction, the resource mapping table is read and the detailed design data of the detailed design model is copied. The model granularity upgrade instruction is obtained by manually triggering it with an interface button, automatically triggering it based on the design stage identifier, or automatically switching it based on the model display ratio. The detailed design data is associated with the conceptual design model in the form of a sub-architecture.

[0040] Specifically, in the early design stages such as engineering planning and pre-feasibility studies, the driving parameters of the conceptual design model are modified to adjust the model's geometric dimensions, topological shape, and positioning coordinates to adapt to the overall layout of the hub and the needs of multi-scheme comparison. In the later design stages such as feasibility studies, bidding design, and construction details, a model granularity upgrade command is obtained. This command can be manually triggered via a button on the design platform interface, automatically triggered based on the design stage identifier, or automatically generated based on the model display scale. After receiving the command, the system reads the resource mapping table that binds the conceptual design model and the detailed design model, and copies the detailed design data such as sub-product components, additive features, and subtractive features from the detailed design model. The copied detailed design data is then attached to the conceptual design model as a sub-architecture of sub-products and sub-parts, realizing the automatic expansion and nesting of the detailed design model, allowing for further detailing of internal sub-objects. Parameter panel adjustment and scheme template replacement can be used to adjust the driving parameters of the conceptual design model, while stage switching scripts and view scaling trigger programs can be used to replace the three command triggering methods. Hierarchical nesting and modular splicing can be used to replace the sub-architecture association. This embodiment achieves seamless progression in the design phase. Lightweight adjustments in the early stage ensure design efficiency, while automatic expansion of detailed models in the later stage avoids repetitive modeling. Multiple triggering methods adapt to different design scenarios, and the sub-architecture association ensures clear model hierarchy and flexible expansion, enabling continuous design across multiple engineering stages.

[0041] Optionally, the multi-stage continuous design method for the engineering model further includes: The target engineering model with standardized characteristics is stored in a standardized container, and the target engineering model with non-standardized characteristics is stored in a non-standardized container. The target engineering models designed by different engineering disciplines are collaboratively assembled to obtain the final target engineering model.

[0042] Specifically, such as Figures 2 to 4As shown, standardized parts of the target engineering model that are completely consistent in design and can be universally reused, such as general beams, columns, standard valves, expansion joints, and fixed-specification components, are stored in a standardized model container. Non-standardized parts of each component that have design differences and require independent modification and adaptation are stored in a non-standardized model container. When these components are reused, the standardized container always points to the same design result to achieve unified reuse, while the non-standardized container allows for independent modification of each component, realizing differentiated design that "seeks common ground while reserving differences" when reusing knowledge. Then, the target engineering models designed by different engineering disciplines such as hydraulics, machinery, electrical, and structure are collaboratively assembled to complete the interface matching, spatial alignment, and logical integration of the models of each discipline. At the same time, different stages of model versions are managed, interface matching is automatically verified, iterative versions are generated, and historical backtracking records are retained, ultimately resulting in a complete and unified final target engineering model. Model tag classification and attribute tag storage can also be used to replace standard / non-standard container storage, and a multi-discipline cloud collaboration platform and real-time online assembly can be used to replace offline collaborative assembly. This embodiment realizes differentiated reuse and standardized promotion of design results, improves the efficiency of design knowledge inheritance, breaks down professional design barriers through multi-disciplinary collaborative assembly, ensures that the models of each profession are consistent and data is unified in the process of stage progression, and is adapted to the characteristics of multi-disciplinary collaborative design of hydropower and pumped storage projects.

[0043] For example, when the target engineering model progresses from the conceptual design stage to the detailed design stage, the project manager updates the status of the conceptual model from "draft" to "released" in the digital design system, triggering the version upgrade. After receiving the model status update instruction, the system automatically sends a notification to the downstream professional design ports, clearly informing them that "upstream data has been updated," and simultaneously prompts the downstream professionals to check in the new model version in a timely manner. When the downstream professionals reference the updated conceptual design model and detailed design model data from the upstream, the system automatically performs a comprehensive check on the matching of interface dimensions, positioning coordinates, topological connection relationships, etc. of the upstream and downstream models. If problems such as interface mismatch, parameter conflict, or geometric logic error are detected, the system immediately issues an alarm to prompt the designers to make corrections. After the downstream professionals complete the model adjustment and update and check in, the system automatically generates a new iterative version of the model, while fully retaining all historical version data, supporting retrospective review of the design process. The system automatically marks the stage progression of "conceptual design → detailed design" in the annotation information of the new version, clearly recording the evolution process of the design stages, which is convenient for subsequent design verification, result traceability, and responsibility definition. This embodiment realizes automated collaborative management and full lifecycle management of multi-disciplinary models during the progressive design phase. It eliminates the tedious operations of manual notification, manual verification, and manual marking, avoids human error and interface matching errors, and ensures data consistency, smooth connection and version traceability of various professional models during the progressive design phase. It provides stable and reliable collaborative management support for multi-stage continuous design of engineering projects.

[0044] Optionally, the multi-stage continuous design method for the engineering model further includes: The conceptual design model and the detailed design model are meshed respectively to obtain the conceptual design finite element model and the detailed design finite element model.

[0045] Specifically, such as Figure 5 and Figure 6 As shown, for the conceptual design model, which mainly consists of the excavation volume or the envelope formed by the excavation face, the model is simultaneously meshed to generate a conceptual design finite element model, specifically for finite element construction simulation analysis of layered excavation. For the detailed design model, which mainly consists of concrete structures, the model is simultaneously meshed to generate a detailed design finite element model, specifically for static and dynamic finite element simulation analysis of concrete structures. When design components are repeatedly called, the finite element model will be generated synchronously along with the geometric model. After the parameters and geometry of the conceptual excavation volume or detailed design volume are updated, the finite element mesh will be updated synchronously. This allows for the completion of finite element calculation and analysis tasks at different design stages, such as planning, pre-feasibility study, feasibility study, and bidding, to achieve simultaneous verification and validation of design results at the same stage. This embodiment achieves synchronous and linked updates of the geometric model and the finite element model, eliminating the need for separate reconstruction of the finite element model. It matches finite element analysis at corresponding depths at different design stages, significantly improving design verification efficiency and ensuring the structural rationality and construction safety of hydropower and pumped storage engineering design results.

[0046] Optionally, the multi-stage continuous design method for the engineering model further includes: Influencing features are defined in the conceptual design model and the detailed design model, and the influencing features include additive features and subtractive features. When spatial interference occurs between components corresponding to multiple target engineering models, the influencing and affected components are identified. Based on the influence characteristics of the conceptual design model and detailed design model of the affected components, matching additive or subtractive topology operations are performed on the affected components to quickly define the spatial topology relationship between multiple components.

[0047] Specifically, such as Figure 7As shown, during the creation of each design component of the project, influence features are preset in both the conceptual design model and the detailed design model of the component. Bosses are used as the influence feature representation of additive design, while slots and openings are used as the influence feature representation of subtractive design, thus completing the standardized definition of influence features. When multiple components within the project hub interfere with each other in spatial arrangement, designers can manually select and specify the affected and influencing components in the interference scenario on the digital design platform. The system automatically performs matching on the affected components according to the influence feature types defined in the conceptual and detailed designs of the influencing components. The topology operations are implemented such that when the influencing feature is a boss additive feature, a boss additive topology operation is performed on the affected component; when the influencing feature is a slotting / hole subtractive feature, a slotting / hole subtractive topology operation is performed on the affected component. This allows for rapid definition of topological relationships between multiple components at arbitrary spatial locations without the need for manual model geometry reconstruction. Furthermore, the system can automatically identify component interference and intelligently match influencing features to replace manual definition of influencing and affected components; it can automatically execute additive / subtractive operations using parametric topology operation scripts to replace manual triggering of topology operations; and it can use feature attribute markers to replace boss / slotting forms to represent influencing features. This embodiment achieves rapid handling of component interference through preset standardized influencing features, accurately adapts to the needs of adjusting component spatial relationships through additive / subtractive topology operations, and completes the definition of multi-component topology relationships without complex modeling. This significantly improves the efficiency of collaborative layout and interference correction of multiple components in hydropower and pumped storage projects, ensuring the rationality of the spatial layout and geometric correctness of each component in the project hub.

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: This embodiment focuses on the digital multi-stage continuous design of the upper reservoir inlet / outlet in the water diversion system of a pumped storage power station. It strictly follows the multi-stage continuous design method of the engineering model described in this application. The specific implementation process is as follows: First, based on the standards for dividing hydropower engineering sub-items, the key structures of the water diversion system are decomposed into independent design objects such as the upper reservoir inlet / outlet, gate well, gatehouse, pressure regulating well, transition section, tunnel section, and pressure steel pipe, and these are classified. Then, the conceptual design features and control parameters of the upper reservoir inlet / outlet are extracted. The inlet / outlet type is determined to be side-mounted. The centerline and positioning axis of the water diversion tunnel, as well as the positioning coordinates of the bottom sill center point (X=1000.0m, Y=500.0m, Z=850.0m), the number of inlet trash rack holes, the width and height of the openings, the outlet dimensions, and the overall length are defined as core parameters. Based on the above parameters, a conceptual design model of the upper reservoir inlet / outlet is constructed in a three-dimensional design platform. This model is as follows: Figure 8As shown, this is a lightweight outline geometry model, presenting only the core shape control volume and key positioning points. It can be quickly adjusted by modifying axis coordinates and direction parameters, allowing for comparison of multiple hub layout schemes. The model file size is approximately 0.8MB, and a single parameter adjustment update takes no more than 10 seconds. Based on the conceptual design model, a detailed design model is expanded, incorporating sub-product components such as anti-vortex beam sections, trash rack sections, adjustment sections, and diffusion sections. Additive features such as maintenance platform bosses and hoist support stretching are generated on the top of the trash rack channel. Simultaneously, subtractive features such as trash rack embedded part grooves and transport track grooves are created, forming a complete detailed design model. The system uses a resource mapping table to bind the conceptual design model and the detailed design model to the same design object type, constructing growable design components and establishing a mapping relationship between key control points of the conceptual model and construction features of the detailed model. This ensures that the detailed model automatically updates when conceptual parameters are modified. In the early pre-feasibility study design phase, the conceptual design model of the component is used to optimize the hub layout. After entering the feasibility study phase, the model granularity upgrade function is activated by clicking a button on the interface. The system reads the resource mapping table, automatically expands the pre-set detailed design model content and parameters, and upgrades the model file size to 15MB. This model is as follows: Figure 9 As shown; subsequently, in the bidding and design phase, the granularity upgrade function is activated again for the selected trash rack section sub-component. This sub-component simultaneously unfolds the pre-set internal details of the first-phase concrete base slab, side walls, central piers, second-phase concrete sill, and reinforcing steel, further expanding the details of the sub-objects within the detailed design model. Finally, the reservoir inlet / outlet model grows from a conceptual outline to a complete model containing all construction details, as shown in the image. Figure 10 As shown, the entire process does not require repeated modeling, and the core control parameters remain consistent, enabling multi-stage continuous design of the pumped storage power station's intake.
