Description

Technical Field

[0001] This invention relates to the field of pumped storage power station design technology, and in particular to an intelligent design method and system based on the comparison and selection of the layout of pumped storage power station hubs. Background Technology

[0002] Pumped storage power stations are large-scale, technically complex, and have high safety requirements. Under the new circumstances, the need to accelerate the preliminary work of survey and design and expedite project approval and construction is particularly strong. Traditional design models, organizational methods, and technical means are no longer suitable for the high-intensity contract performance requirements. In particular, the selection of the hub layout during the feasibility study stage involves the coordinated layout of multiple types of structures, such as water-retaining structures, water conveyance systems, power plants, and switchyards. The spatial relationships between these structures are complex, and multiple constraints such as geological conditions, construction difficulty, and operational efficiency must be taken into account. The workload of scheme comparison is enormous, usually requiring a technical and economic comparison of 3-5 hub layout schemes. Each scheme requires systematic work such as model building, engineering quantity statistics, and investment estimation. Different schemes have significant differences in terrain adaptability and geological compatibility, requiring repeated adjustments to the axis positions and elevations of the structures. Given the current tight schedule and heavy workload of the feasibility study stage, the ability to quickly select the hub layout and complete the tasks of report preparation, drawing production, and bill of quantities preparation in a short period of time is crucial to the project.

[0003] BIM technology has been widely used in hydropower engineering design. Parametric modeling based on BIM technology has been widely applied to the modeling and optimization of individual buildings such as dams and powerhouses. However, it still faces systemic shortcomings when comparing and selecting overall layout schemes for the project: 1) The BIM models of each individual building lack unified data standards and collaborative platforms, resulting in the fragmentation of key information such as building spatial relationships and engineering quantity data between different schemes; 2) The scheme comparison process is highly dependent on manual operation. Designers need to manually extract characteristic parameters, engineering quantities, and costs of each scheme and make horizontal comparisons using tools such as Excel. This discrete processing method is not only inefficient but also prone to data transcription errors; 3) Existing technologies are difficult to achieve dynamic optimization of the layout scheme of the project. For example, when adjusting the location of the powerhouse, the water conveyance system route or earthwork volume calculation cannot be automatically updated synchronously, which restricts the design iteration speed.

[0004] Therefore, there is an urgent need to provide a method that can quickly and efficiently achieve intelligent comparison and design of multiple hub layout schemes. Summary of the Invention

[0005] This invention provides an intelligent design method and system for comparing and selecting the layout of pumped storage power station hubs, in order to solve the problem that there is a lack of intelligent design methods in the prior art that can quickly and efficiently realize multiple schemes for hub layout.

[0006] In a first aspect, this application provides an intelligent design method based on the comparison and selection of the layout of pumped storage power station hubs, characterized by comprising: Obtain basic data and information on pumped storage power stations; Based on the aforementioned basic information, a hub layout comparison scheme is planned to generate model design files corresponding to various comparison schemes, and a corresponding comparison scheme report template file is matched for each comparison scheme. Based on the model design file, intelligent design is performed on each module of all hydraulic structures of the pumped storage power station, and the model design file is updated. The updated model design file is processed to obtain a lightweight model file, PDF drawings, quantities, and feature parameters. Based on the aforementioned lightweight model file, PDF drawings, engineering quantities, and characteristic parameters, a hub layout comparison and design was carried out. A hub pattern comparison report is generated based on the results of the hub pattern comparison and design.

[0007] Secondly, this application provides an intelligent design system for the layout selection of pumped storage power station hubs, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the method described in the first aspect above.

[0008] The present invention has the following beneficial effects: This application presents an intelligent design method for the selection of layout patterns of pumped storage power station hubs. Through scheme planning, intelligent BIM design, automated and lightweight model processing, and BIM design for the selection of layout patterns of hubs from scheme design to output, a complete intelligent design method for the selection of layout patterns of pumped storage power station hubs is formed. Finally, the design results of the selection of layout patterns of hubs are automatically output, which can quickly and efficiently realize the intelligent selection and design of multiple schemes of hub layout.

[0009] In addition to the objectives, features and advantages described above, the present invention has other objectives, features and advantages.

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.

[0014] Please see Figure 1 This application provides an intelligent design method based on the comparison and selection of the layout of pumped storage power station hubs, including: Obtain basic data and information on pumped storage power stations; Based on the aforementioned basic information, a hub layout comparison scheme is planned to generate model design files corresponding to various comparison schemes, and a corresponding comparison scheme report template file is matched for each comparison scheme. Based on the model design file, intelligent design is performed on each module of all hydraulic structures of the pumped storage power station, and the model design file is updated. The updated model design file is processed to obtain a lightweight model file, PDF drawings, quantities, and feature parameters. Based on the aforementioned lightweight model file, PDF drawings, engineering quantities, and characteristic parameters, a hub layout comparison and design was carried out. A hub pattern comparison report is generated based on the results of the hub pattern comparison and design.

[0015] In this application, each alternative will correspond to a report template. After the comparison is completed, the data in the model will be extracted and replaced with the data in the template to generate a part of the hub pattern report.

[0016] The aforementioned intelligent design method for selecting the layout of pumped storage power station hubs forms a complete intelligent design method for selecting the layout of pumped storage power station hubs through scheme planning, intelligent BIM design, automated and lightweight model processing, scheme design and output of results. Finally, it automatically outputs the design results of the hub layout, which can quickly and efficiently realize the intelligent selection and design of multiple hub layout schemes.

[0017] The steps of the intelligent design method based on the comparison of the layout of pumped storage power station hubs are described below with a complete example: Step (1): Input basic hydrological, meteorological, sediment, hydropower parameters, kinetic parameters, planning, electromechanical and other basic data of the project into the intelligent design platform of the pumped storage power station.

[0018] Step (2): Conduct a comparative analysis of the hub layout and plan the alternative schemes.

[0019] This step clarifies the selection of dam site, upper reservoir dam line, upper reservoir dam type, upper reservoir spillway structures, lower reservoir dam line, lower reservoir dam type, lower reservoir spillway structures, water conveyance system route, powerhouse development method, water conveyance system facade layout, and switchyard layout, and generates model design documents and matching report templates for each selection scheme.

[0020] Step (3): Conduct intelligent building design based on the generated model design file.

[0021] The intelligent design software includes nearly 20 modules covering all hydraulic structures of pumped storage power stations, such as panel rockfill dams, gravity dams, clay core dams, spillway tunnels, vertical shaft spillway tunnels, spillways, full reservoir seepage prevention, reservoir expansion excavation, intelligent dam line layout, underground powerhouse, switchyard, auxiliary caverns, water conveyance system, diversion structures, schedule design, earthwork balance, and overall construction layout.

[0022] In this step, the generated model design file is opened, and the basic data is obtained by using the intelligent design module of different buildings in the intelligent design tool software to carry out specific building design. The design includes 3D modeling, bill of quantities statistics, drawings, feature parameter processing and other work. Each model design file saves the model, drawings, and data such as quantities and feature parameters in the model design file using EC attribute binary values. Different disciplines use the ProjectWise collaborative design platform to collaborate and store the model design file.

[0023] The following mainly introduces the intelligent design process of two modules. Since the intelligent design process of each module is similar, this section uses the intelligent design process of two modules as an example and does not exhaustively list the intelligent design process of all modules.

[0024] 1) Intelligent design of panel rockfill dams: (1) Definition of dam axis By introducing three-dimensional terrain data, defining the dam axis position, determining the dam crest elevation, defining the dam axis 0+000 point and the left and right directions of the dam, and determining the logical relationship of the dam's three-dimensional orientation, the basic design conditions for subsequent work are laid.

[0025] (2) Design of typical dam sections The typical cross-section design of a dam mainly includes the design of the dam crest structure and the zoning of the fill material. The dam crest structure includes upstream and downstream wave walls, a dam crest road, and cable trenches. The fill material mainly includes the overburden (crushed stone cushion layer, completely weathered soil, and fly ash), cushion material, special cushion material, transition material, slope joint material, main rockfill material, and downstream rockfill material. The typical cross-section design of the dam is mainly used for the subsequent generation of the three-dimensional dam structure through its intersection with the terrain of the dam foundation excavation.

[0026] (3) Toe plate alignment By introducing a geological model, the toe plate line can be adjusted in real time, greatly reducing the back-and-forth mapping process between the early design and geological professionals.

[0027] (4) Excavation of dam foundation and abutment Based on the geological model, the dam axis and toe plate X-line are determined. Following the principles of regulatory requirements and the design concept of the actual project, the dam foundation and abutment excavation model is quickly generated after inputting basic design data.

[0028] (5) Parametric 3D Modeling of Dam By inputting basic design data, parametric modeling of each basic section of the panel dam can be achieved, which facilitates modification and greatly reduces repetitive work. At the same time, during the input of basic data, the structural shape design of the toe plate and panel is introduced to determine its rationality and achieve forward design.

[0029] (6) Output of major engineering quantities By automatically extracting relevant model and basic data, the engineering quantities of the panel dam can be automatically generated, and the standardized calculation drafts of the toe slab and panel structure can be automatically output. The design depth needs to meet the requirements of the key layout topic in the feasibility study stage.

[0030] (7) Output of design drawings Based on the model attributes and basic input parameters, and combined with relevant typical drawings, the following are generated: dam plan layout, dam x-line development along the toe plate, dam axis section, typical dam section, and some related detailed drawings.

[0031] 2) Intelligent design of gravity dams: (1) Definition of dam axis Set the dam axis line, select the drawn dam axis line, cut it and display it for longitudinal section design. The longitudinal section should show the original topographic lines, the weathering boundaries (full, strong, weak, and slight), and the top line of the relatively impermeable layer.

[0032] The system automatically marks a straight line on the longitudinal profile, indicating the dam crest elevation. The dam crest length can be determined by selecting a point and inputting the dam length, or by directly selecting two points on the line. The system automatically records the elevation and station number of the control points A and B on the left and right dam abutments, and marks the position of station number 0+000.000 on the left / right side of the dam. (2) Foundation design Segmented Design: By selecting or entering the location of the joints, the dam is divided into segments, and each segment is automatically numbered from left to right. Non-overflow dam segments, overflow dam segments, etc., can be identified by entering the dam segment number or selecting a dam segment.

[0033] Foundation surface design: Set the width of the foundation platform for a single dam section to 1 / 3 of the dam section width; determine the horizontal depth of platform excavation based on the geological weathering line (measured from the outermost corner of the platform); determine the recommended step height and excavation slope ratio; based on the above principles, the platform automatically generates the dam foundation surface.

[0034] Starting from the left abutment A, the system automatically records and sequentially numbers the coordinates of the baseline inflection points, ending at the right abutment B. After automatic generation by the platform, designers can manually adjust the inflection points or the slope ratio of each excavation baseline segment. They can also add or delete inflection points on the already drawn baseline, enabling rapid modification of the foundation surface. Future versions of this function should include direct import and intelligent wiring capabilities.

[0035] (3) Design of the cross section of the dam section By inputting the maximum dam height, dam crest elevation, upstream and downstream slope points, and upstream and downstream slope ratio, a cross-section of the water-retaining structure that meets the design requirements can be obtained. Boolean operations are then performed on the foundation surface module to realize the modeling of the water-retaining structure.

[0036] (4) Design of the cross section of the spillway dam Overflow weir model design: Based on hydraulic calculations, parameters are adjusted to modify the surface overflow dam section shape to suit this project. Key parameters include downstream starting elevation, slope ratio, upstream starting elevation, and slope ratio. Other parameters include the upstream crest curve (generally a triple-circle curve), crest elevation, weir face power curve, downstream slope, downstream inversion arc starting point, inversion arc radius, and tilt angle. After shape modification, concrete zoning design is performed. Each dam section is zoned into a closed polygonal region, named and confirmed by point selection. Typical cross-sections for this project are stored.

[0037] Gate pier and guide wall design: Through the interactive interface, fill in the design parameters for the gate pier and guide wall. By modifying parameters such as the thickness of the gate pier and guide wall, and the cantilever length, determine the cross-sectional shape and dimensions of the gate pier, thereby forming a closed polygonal area for each gate pier. Name and confirm by clicking.

[0038] Design of the short pressurized central orifice section model: Based on hydraulic calculations, parameters were adjusted to modify the central orifice dam section shape to suit this project. After the shape modification, concrete zoning design was carried out. Each dam section zoning formed a closed polygonal region, which was named and confirmed by point selection. A typical cross-section of this project was saved.

[0039] Guide wall design: Enter guide wall design parameters through the interactive interface. By modifying parameters such as gate pier guide wall thickness and cantilever length, determine the cross-sectional shape and dimensions of the gate pier, thereby forming a closed polygonal area for each gate pier. Name and confirm by clicking.

[0040] (5) Design of seepage prevention curtain Starting from a point on the straight line where the dam crest elevation is located, draw the curtain bottom line on the longitudinal profile according to the principle of determining the curtain bottom line (generally 5-10m below the impermeable layer line). The system automatically records the coordinates of the bottom line inflection points and sequentially numbers them (W). The endpoint is another point on the straight line where the dam crest elevation is located. Modification and subsequent functions should be consistent with the excavation bottom line of the foundation surface.

[0041] (6) Dam assembly modeling Overall dam model: Based on the foundation surface design module, the various structures are assembled. The foundation is cut according to the foundation surface, and the area within 2m above the foundation surface is the foundation cushion concrete zone.

[0042] Dam foundation excavation model: Automatically extract the foundation surface of the overall dam model and generate the dam foundation excavation model according to the different excavation slope ratios on the upstream and downstream sides.

[0043] Dam shoulder excavation: Determine the elevation of the dam shoulder platform. After determining the elevation, the software automatically extracts the contour lines of that elevation. Designers draw the slope start line of the dam shoulder slope. Determine the excavation direction, set the number of excavation stages, slope ratio, and slope height, complete the excavation, and calculate the excavation volume.

[0044] Dam crest structure: The dam crest structure determined during the cross-sectional design can be stretched along the dam axis to the left and right bank shoulders.

[0045] Curtain grouting modeling: In the longitudinal section design, a closed polygon is formed by the excavation bottom line of the foundation surface and the curtain grouting bottom line.

[0046] (7) Calculation of project quantity The main output quantities include: dam foundation consolidation grouting, contact grouting, and curtain grouting; concrete for each building section; dam crest structure and waterstop; reinforcement; dam foundation excavation, drainage, and support; see the standard template for concrete gravity dam quantity calculation for details.

[0047] (8) Automatic drawing generation Automatically generate the hub layout plan, the upstream elevation view of the dam, the typical cross section view of the dam, and detailed drawings.

[0048] Step (4): Lighten all model design files.

[0049] In this step, the backend service periodically queries all updated model design files in the ProjectWise collaborative design platform and automatically submits the updated files to the lightweight platform. The lightweight platform then performs lightweight processing on the modified model design files. This lightweight processing mainly includes converting the 3D model into a lightweight model file for front-end display, outputting the drawings in the model design file as PDF format, and writing the attribute files containing engineering quantities and feature parameters from the model design file into a text file as JSON strings. After the backend service detects that the lightweight task is completed, it stores the lightweight model files, PDF drawing files, and the extracted JSON strings from the attribute files in separate directories and parses and stores the data in the intelligent design platform database for pumped storage power stations.

[0050] It is worth noting that the model design file can only be opened on the Microstation software and cannot be opened on the intelligent design platform for pumped storage power stations. Therefore, by lightweighting this file into a format that can be recognized by a web platform and synchronously transmitting the various EC attributes of the file in the model design file, the ease of implementation can be improved.

[0051] Step (5): Conduct a comparative design of the hub layout.

[0052] The intelligent design platform for pumped storage power stations uses lightweight model files, PDF drawings, and database-stored engineering quantities and characteristic parameters to perform comparisons of dam site selection, upper reservoir dam line selection, upper reservoir dam type selection, upper reservoir spillway structures, lower reservoir dam line selection, lower reservoir dam type selection, lower reservoir spillway structures, water conveyance system line selection, powerhouse development method, water conveyance system facade layout selection, and switchyard layout. It automatically generates professional comparison conclusions and scheme comparison conclusions, as well as corresponding comparison chapter reports.

[0053] The following mainly introduces the comparison process of two schemes. It is worth explaining that this is only an example and not a limitation. Since the comparison process of each scheme is quite similar, this only illustrates the comparison process of two schemes and does not exhaustively describe them.

[0054] 1) Dam type comparison for the upper reservoir: Two dam types were compared: concrete gravity dam and concrete-faced rockfill dam.

[0055] (1) Model building. Intelligent design software was used to build BIM models of concrete gravity dams and concrete-faced rockfill dams; (2) Parameter extraction. Extract the quantities and feature data from the two models; (3) Comparison of project quantities. The project quantities of the two schemes were compared and selected from aspects such as open excavation of earth and rock, tunnel excavation of rock, dam filling, concrete, steel reinforcement installation, curtain grouting, consolidation grouting, anchor bolts and drainage holes, and total project investment. The scheme with better project quantity was identified by comparing several key indicators such as total project investment, tunnel excavation of rock, and dam filling. (4) Technical and economic comparison. Compare and analyze the topographical conditions, geological conditions, hub layout, building materials, construction conditions, and maintenance conditions to identify the better technical and economic option; (5) Based on the engineering quantity and technical and economic comparison results, a comprehensive analysis is conducted to form the final recommended scheme for dam type comparison, and a dam type comparison chapter report is automatically generated.

[0056] 2) Water transmission system route comparison: The southern and northern routes are compared.

[0057] (1) Model building. Intelligent design software was used to build BIM models of the southern and northern routes of the water conveyance system; (2) Parameter extraction. Extract the quantities and feature data from the two models; (3) Comparison of water conveyance system layout. The water conveyance system layout is compared from the aspects of characteristic data such as the inlet and outlet of the upper reservoir, water diversion tunnel, water diversion surge tank, tailrace tunnel, tailrace surge tank, inlet and outlet of the lower reservoir, total length of water conveyance system, and Ta / Tw. The recommended better scheme is determined by comparing key indicators such as line length, hydraulic calculation results, and Ta / Tw. (4) Comparison of power plant layout. The two schemes were compared in terms of the length of auxiliary caverns, including the length of access tunnels, ventilation and safety tunnels, high-voltage cable tunnels, and gravity drainage tunnels. The better scheme was recommended in terms of length.

[0058] (5) Comparison of construction adits. The optimal scheme is determined based on the total number and total length of construction adits.

[0059] (6) Comparison of geological conditions. The optimal solution is determined by comparing the topography, strata, lithology, geological structure, and hydrogeology.

[0060] (7) Comparison of project quantities. Compare the options for earthwork open excavation, rock excavation tunneling, dam filling, concrete, steel reinforcement installation, curtain grouting, consolidation grouting, anchor bolts and drainage holes, and determine the option with the better project quantity based on the main indicators.

[0061] (8) Project investment comparison. Based on the analysis of water transmission system, plant system, construction auxiliary works, and total investment, the better scheme is recommended.

[0062] (9) Determine the recommended route selection scheme. Based on a comprehensive analysis of the water conveyance system layout, power plant layout, construction tunnel layout, geological conditions, engineering quantity, and engineering investment, determine the final recommended route selection scheme and automatically generate a route selection chapter report.

[0063] Step (6): Generate a hub pattern comparison report.

[0064] Based on the comparison conclusions and scheme comparison conclusions of various professional comparisons, including dam site selection, upper reservoir dam line selection, upper reservoir dam type selection, upper reservoir spillway structures, lower reservoir dam line selection, lower reservoir dam type selection, lower reservoir spillway structures, water conveyance system route selection, powerhouse development method, water conveyance system facade layout selection, and switchyard layout, and using the built-in tag-based report template, the entire project hub layout comparison report is automatically generated.

[0065] This application also provides an intelligent design system for the comparative selection of layout patterns of pumped storage power station hubs, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the above-described method.
