DETAILED DESCRIPTION

[0017] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application. Based on the examples in the present application, all other examples obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0018] The present application relates to the field of power engineering technology and digital modeling, and can be widely applied to the whole-process cost management of UHV substation, converter station and transmission line engineering, including the engineering quantity statistics, measurement comparison and cost early warning in the stages of estimation, budget estimation, budget and settlement, and is especially suitable for UHV power transmission and transformation engineering construction projects which require high-precision and high-efficiency engineering quantity calculation.

[0019] In the existing UHV power transmission and transformation engineering budget estimation business, due to the relatively independent engineering design and engineering cost link, the insufficient support of three-dimensional design model information to quantity calculation, the lack of professional adaptability of measurement rules and the absence of effective process early warning mechanism, the following problems mainly exist: (1) In the design process, the three-dimensional design model only focuses on meeting the design specification and parameter requirements, and the key information required for engineering quantity calculation (such as equipment rated voltage, component cross-sectional size, material density, etc.) is not fully supplemented, and a unified object classification, naming and attribute standard is not formed, resulting in information differences between the design model and the quantity calculation model, and the cost personnel need to spend a lot of time to organize and complete the information, which not only increases the work burden, but also easily reduces the quantity calculation accuracy due to information omission or deviation. At the same time, the multi-specialty pipeline (such as electrical cable bridge, water supply and drainage pipeline) design lacks a collaborative optimization mechanism, and pipeline collision or unreasonable spatial arrangement is easy to occur, and problems need to be found in the subsequent construction stage to make design changes, which further leads to engineering quantity rework calculation and cost overrun.

[0020] (2) For the calculation and control of engineering quantity, the existing technology mainly relies on the sequential process of "CAD (Computer-Aided Design) design-BIM (Building Information Modeling) model rebuilding-quantity calculation and pricing", the model rebuilding process needs additional time cost, and the geometric size or parameter deviation may be caused by model rebuilding, resulting in the inconsistency between the BIM model and the original design information; at the same time, the differentiated calculation rules are not formulated for the professional characteristics of the ultra-high voltage power transmission and transformation project (including the substation, converter station and power transmission line), such as the unclear mapping relationship of the calculation unit, calculation logic and list quota of the electrical equipment (transformer, GIS combined electrical) and power transmission component (conductor, tower), which needs manual intervention for matching, reducing the efficiency of quantity calculation. In addition, there is a lack of reference comparison and early warning mechanism based on historical engineering data, which cannot identify the engineering quantity anomaly (such as the number of a certain type of equipment far exceeding the average of similar projects) in real time in the design stage, and can only be checked after the completion of the cost preparation, which may easily lead to cost overrun or waste of engineering materials.

[0021] The existing engineering quantity calculation method for ultra-high voltage power transmission and transformation project has obvious shortcomings in information transmission, calculation efficiency, professional adaptability and process control, and a professional, automated and full-process engineering quantity calculation system based on three-dimensional design needs to be built to meet the demand of high-quality construction of ultra-high voltage project.

[0022] Based on the above problems, the present application provides the following key improvements.

[0023] (1) In the project environment, a standardized system of three-dimensional design model information is built, the model object classification standard (classified according to the professional and cost stage) is defined, the key attribute information of quantity calculation (such as equipment rated parameter and component material specification) is supplemented, and multi-professional pipeline optimization (collision detection and arrangement adjustment) is implemented, so as to eliminate the information fault between design and cost, make the three-dimensional design model directly serve as the basic carrier for engineering quantity calculation, eliminate the need for additional model rebuilding, and improve the information transmission integrity and pre-position efficiency of quantity calculation.

[0024] (2) The differentiated calculation rules for ultra-high voltage power transmission and transformation project are formulated, the calculation logic is designed according to the component calculation unit (number, length, area, volume / weight), the engineering quantity is automatically calculated by combining the Brep topology analysis and Boolean operation technology, the historical engineering reference quantity query library is established, the real-time comparison between the new project and the historical data triggers the abnormal early warning, the engineering quantity deviation is corrected in time in the design stage, the whole-process control of "design-quantity calculation-early warning" is realized, and the engineering quantity calculation accuracy and cost controllability are improved.

[0025] The specific embodiments of the present application are described in the following Examples 1 to 4.

[0026] Embodiment one The embodiment of the present application provides a design engineering quantity control method based on an extra-high voltage power transmission and transformation project, as shown in the figure, the method comprises steps S1-S5, wherein: Figure 1 Step S1, a three-dimensional design model of a target extra-high voltage power transmission and transformation project is acquired; wherein the three-dimensional design model comprises a plurality of model components, each model component has an identity, and the identity comprises a specialty to which the model component belongs, a component type of the model component and a specification model of the model component. Step S1, a three-dimensional design model of a target extra-high voltage power transmission and transformation project is acquired; wherein the three-dimensional design model comprises a plurality of model components, each model component has an identity, and the identity comprises a specialty to which the model component belongs, a component type of the model component and a specification model of the model component.

[0027] The identity comprises a longitudinal multi-level label. The first level label is the specialty to which the model component belongs, such as the civil engineering specialty, the electrical engineering specialty or the power transmission specialty; the second level label is the component type of the model component, such as the transformer, the wire or the tower, etc.; and the third level label is the specification model of the model component, such as the 500kV oil-immersed type or the 240 square millimeter. The identity examples are as follows: electrical engineering specialty-transformer-500kV oil-immersed type, power transmission specialty-wire-240 square millimeter.

[0028] Wherein, the classification standard of the model component is defined in advance according to the specialty division (civil engineering, electrical engineering, power transmission, etc.) and the cost stage (estimation, budget, budget, etc.) of the extra-high voltage power transmission and transformation project: According to the specialty, the civil engineering component (wall, beam, column, foundation, etc.), the electrical equipment (transformer, circuit breaker, insulator, etc.) and the power transmission component (wire, ground wire, tower, etc.) are divided. According to the cost stage, the classification granularity is adjusted, for example, the “small installation part” in the budget stage is classified according to the room area, and the budget stage is disassembled into valve, pipe and other independent objects.

[0029] The identity of the model component is determined in the BIM software through a three-level structure, so that the component identity can be automatically recognized by the computer and matched with the metering algorithm.

[0030] Step S2, the engineering quantity of the three-dimensional design model is estimated based on the identity of each model component, as the design engineering quantity.

[0031] The component type and the specification model in the identity are taken as the first granularity, the engineering quantity of each first granularity of the model component in the three-dimensional design model is counted, then the specialty in the identity is taken as the second granularity, the engineering quantity corresponding to all first granularities under each specialty is counted, and the design engineering quantity is obtained.

[0032] For example, when the engineering quantity is counted according to the first granularity, for the identity: electrical specialty-transformer-500kV oil-immersed, the total number of 500kV oil-immersed transformers is counted; for the identity: electrical specialty-transformer-220kV dry-type, the total number of 220kV dry-type transformers is counted; for the identity: power transmission specialty-conductor-240 square millimeter, the total length of 240 square millimeter conductors is counted. Further, when the engineering quantity is counted according to the specialty, the electrical specialty includes: the total number of 500kV oil-immersed transformers and the total number of 220kV dry-type transformers; the power transmission specialty includes: the total length of 240 square millimeter conductors.

[0033] Optionally, the engineering quantity of the three-dimensional design model is estimated based on the identity of each model component, as the design engineering quantity, including: determining a component group associated with each component type based on the identity of each model component; wherein the model components in each component group have the same component type; adding a key attribute required for calculating the engineering quantity to each model component in each component group; wherein the model components in the same component group have the same attribute name of the key attribute; estimating the engineering quantity of the three-dimensional design model based on the added key attribute, as the design engineering quantity.

[0034] Specifically, all model components belonging to the same specialty are determined by using the first layer of labels of the identity, and then the component group associated with each component type under the specialty is determined among all model components under each specialty by using the second layer of labels of the identity. The component group includes several model components, the model components under the same component type have the same attribute name of the key attribute, the model components of the same specification and model under the same component type have the same attribute value of the key attribute, and the model components of different specifications and models under the same component type have different attribute values of the key attribute. After adding the key attribute, the engineering quantity of each model component in the three-dimensional design model can be calculated to obtain the design engineering quantity of the three-dimensional design model.

[0035] The specific steps of adding the key attribute to the model components in a component group are taken as an example, and the specific steps of adding the key attribute are analyzed in detail, wherein the steps of adding the key attribute to each component group are highly similar.

[0036] Optionally, the key attribute required for calculating the engineering quantity is added to each model component in the component group, including: reading the key parameter required for calculating the engineering quantity associated with the component type; wherein different component types are associated with different key parameters; adding the key parameter as the attribute name of the key attribute to the component information of each model component in the component group; Based on the regular type of each model component in the component group, an attribute value is set for the attribute name of the key attribute in the component information of each model component.

[0037] Based on the information difference between the design model and the calculation model, a set of measurement key attributes is supplemented for each type of model object of the three-dimensional design model. The key parameters include one or more parameters: when the key parameters include one parameter, the corresponding key attribute includes one attribute, and the attribute name of the attribute is the key parameter; when the key parameters include N parameters, the corresponding key attribute includes N attributes, and the attribute name of each attribute is one of the key parameters, N is an integer greater than 1. Wherein, the key parameter can be associated as an attribute name to the component information of the model component in the form of a shared parameter or an instance parameter. The shared parameter represents that the key parameter can be referenced by multiple model components, and the instance parameter represents that the key parameter can only be referenced by one model component.

[0038] For example, for the electrical profession, the key attributes supplemented by the transformer include: rated voltage, rated capacity, insulation mode, installation mode, and the key attributes supplemented by the circuit breaker include: rated current, rated short-circuit breaking current, and insulation medium; for the civil profession, the key attributes supplemented by the wall include: axis length, top and bottom elevation, and construction column position, and the key attributes supplemented by the foundation include: concrete grade, steel consumption, and anchor bolt weight; for the power transmission profession, the key attributes supplemented by the conductor include: stringing mode, loop number, and line weight, and the key attributes supplemented by the tower include: tower type, tower height, and single foundation weight.

[0039] The original three-dimensional design model is a geometric model containing size, shape, position and other information, but it is severely lacking in technical and economic parameters required for cost calculation (such as voltage grade, concrete grade). By supplementing the measurement key attributes to the three-dimensional design model, a pure geometric model is upgraded to a cost data model rich in information, which makes the BIM model not only a visual shell, but also a unique and reliable data source that can be directly used for quantity calculation, solves the information fault problem, and enables the three-dimensional design model itself to be used for quantity calculation, eliminating the time-consuming and error-prone model conversion work. At the same time, it also provides assistance for subsequent automatic calculation. Only when the computer reads these structured parameters (such as rated capacity, concrete grade) can it execute accurate quantity calculation rules and price matching.

[0040] Optionally, after supplementing the key attributes, the multi-professional pipelines of the substation and the converter station can also be comprehensively optimized based on the BIM visualization characteristics: Fusing architectural, structural, electrical, water supply and drainage, and other professional models, through collision detection function to identify the conflict points of pipelines and equipment, pipelines and structure, such as the overlap of cable bridge and beam, and the interference of grounding electrode and foundation. According to the principle of "maximizing space utilization and minimizing pipeline bending", the pipeline arrangement is adjusted, such as optimizing the cable bridge direction to reduce the number of bends, and adjusting the protection pipe elevation to meet the floor clearance requirements. The optimized pipeline model is geometrically checked to ensure that the pipeline length, pipe diameter, connection mode and other parameters are consistent with the design specifications, forming a refined model that can be directly used for engineering quantity calculation.

[0041] Optionally, the engineering quantity of the three-dimensional design model is estimated based on the added key attributes as the design engineering quantity, comprising: Obtain a preset engineering quantity calculation logic; wherein the engineering quantity calculation logic comprises a plurality of engineering quantity calculation rules and a component type applicable to each engineering quantity calculation rule; Determine the engineering quantity calculation rule applicable to each model component based on the identity of each model component in the three-dimensional design model, and estimate the engineering quantity of each model component based on the engineering quantity calculation rule applicable to each model component; Taking the component type and model specification in the identity as the first granularity, the engineering quantity of the model component under each first granularity is counted; Taking the specialty in the identity as the second granularity, the engineering quantity corresponding to all first granularities under each specialty is counted to obtain the design engineering quantity.

[0042] Preferably, four engineering quantity calculation rules are determined according to the measurement unit of the model component, and the four engineering quantity calculation rules comprise: quantity-based engineering quantity, length-based engineering quantity, area-based engineering quantity, and volume / weight-based engineering quantity.

[0043] The quantity-based engineering quantity is applicable to independent devices such as transformers, circuit breakers, disconnectors, towers, etc., and the calculation logic is as follows: The number of objects of the same category is counted through the type selector of the BIM software, such as filtering GIS (Gas Insulated Switchgear) combined electrical equipment with a rated voltage of 500kV and counting; For components that need to be measured by group / set (such as lightning arresters, battery packs), the final engineering quantity is automatically converted according to the preset single group containing quantity (such as 1 group of lightning arresters containing 3 devices).

[0044] The length-based engineering quantity is applicable to linear components such as conductors, ground wires, cables, cable bridges, and protection pipes, and the calculation logic is as follows: Based on the positioning reference geometry of the model object (the laying curve for conductors and the axis straight line for bridges), the geometric length is obtained through Brep topology analysis; For components that need to consider cross-section parameters (such as soft conductors, hard conductors), associate cross-sectional area attributes, match quota sub-items (such as 240 square millimeter soft conductor erection), and calculate derived quantities by length multiplied by cross-sectional correlation coefficient (such as when weight conversion is required).

[0045] Area-based engineering quantity is suitable for formwork, painting, floor and other planar components. The calculation logic is as follows: For floor, the axis size area of the laying area is obtained by Brep topology analysis, without deducting non-computing areas such as staircases and openings; For painting engineering (such as pole tower painting), based on the Brep surface set of the component surface, the total area of all surfaces that need to be painted is calculated, excluding bolt holes, connection flanges and other non-painting areas.

[0046] Volume / weight-based engineering quantity is suitable for walls, beams, columns, foundations, and other civil components. The calculation logic is as follows: Volume calculation: obtain the component entity volume through Brep topology, and perform Boolean subtraction operation to deduct the overlapping volume for the intersection part of wall and structural column, beam and slab (such as wall volume = wall overall volume - structural column embedded volume); Weight calculation: for steel reinforcement and steel components, automatically convert based on "volume x density" (such as steel density 7.85 tons / cubic meter), or directly associate single weight attribute (such as ground screw bolt single weight 0.5 tons) and multiply by quantity.

[0047] For civil engineering, calculate wall, beam, column, foundation quantities according to the above volume / area / length rules, such as wall height calculated as "foundation beam top elevation to parapet top elevation", and floor area calculated as axis size; For substation / converter station, calculate electrical equipment and pipeline quantities according to the number / length rule, such as GIS combined electrical according to the number of tables, and cable according to the length; For transmission, calculate conductor, tower, foundation quantities according to the number / length / volume rule, such as tower according to the base, and earthwork according to the excavation volume (hole depth x hole diameter x soil coefficient).

[0048] The calculated quantities (such as 3 transformers, 5km conductors) and matching list / quota items (such as 500kV transformer installation, 240 square millimeter conductor erection) are written back to the corresponding model object properties through the "parameter assignment" function of BIM software; according to the professional, system (such as "500kV main transformer system", "transmission line tower system"), the quantities are summarized to generate Excel or BIM model format of the bill of quantities, which supports direct import into pricing software to generate cost files.

[0049] Step S3, determining a historical UHV power transmission and transformation project with a similarity greater than a similarity threshold to the engineering scale of the target UHV power transmission and transformation project, and obtaining the quantities of the three-dimensional calculation model of the historical UHV power transmission and transformation project as the calculation quantities.

[0050] For the completed UHV project, the quantity data (including original quantities, list quota items, engineering stages, and professional classifications) in the standardized model are structured, and are stored in tables according to “engineering voltage level-professional-component type”, that is, the calculation quantities include multiple data tables, and each data table stores the quantities of the model components of a component type under a professional. For example, the “500kV substation-electrical professional-transformer” data table. At the same time, the retrieval parameters (such as engineering type and construction year and equipment model) are set for the query library, and multiple condition combination queries are supported, such as querying the reactor quantities of the 500kV converter station completed in 2023.

[0051] Step S4, comparing the design quantities and the calculation quantities to obtain a comparison result.

[0052] The comparison result can include the comparison results of the quantities of each first granularity in the design quantities and the calculation quantities, or the comparison results of the quantities of part of the first granularities in the design quantities and the calculation quantities.

[0053] Optionally, the comparing the design quantities and the calculation quantities to obtain a comparison result includes: respectively calculating the deviation values between the quantities corresponding to each first granularity in the design quantities and the quantities corresponding to each first granularity in the calculation quantities under each professional; wherein the deviation values carry positive / negative signs; when the deviation value exceeds the preset deviation range, determining the model component corresponding to the deviation value in the three-dimensional design model and determining the quantity corresponding to the deviation value in the calculation quantities; generating the comparison result of the design quantities and the calculation quantities; wherein the comparison result includes multiple comparison records, and each comparison record includes a deviation value exceeding the preset deviation range, a model component corresponding to the deviation value in the three-dimensional design model, and a quantity corresponding to the deviation value in the calculation quantities.

[0054] The absolute values of the left and right extreme values of the preset deviation range are the same, and the signs are opposite. For example, the preset deviation range is [-10%, 10%].

[0055] For example, in the electrical specialty, if the statistical quantity of 500 kV oil-immersed transformers in the design engineering quantity is 3, and the statistical quantity of 500 kV oil-immersed transformers in the calculated engineering quantity is 3, the deviation value of the two must be less than the preset deviation threshold; if the statistical quantity of 500 kV oil-immersed transformers in the calculated engineering quantity is 2.

[0056] For another example, in the power transmission specialty, if the total length of 240 square millimeter conductors in the design engineering quantity is 3 km, and the total length of 240 square millimeter conductors in the calculated engineering quantity is 2.5 km, the deviation value of the two is 20%, if it exceeds the preset deviation threshold, the early warning is triggered, otherwise the early warning is not triggered.

[0057] Step S5, when the comparison result represents that the deviation value between the design engineering quantity and the calculated engineering quantity exceeds the preset deviation range, adjusting the three-dimensional design model, so that the deviation value between the design engineering quantity of the adjusted three-dimensional design model and the calculated engineering quantity is within the preset deviation range.

[0058] Wherein, the deviation value between the design engineering quantity and the calculated engineering quantity greater than the preset deviation threshold can represent that the deviation value between the engineering quantity of any one or more first granularities in the design engineering quantity and the engineering quantity of the corresponding first granularity in the calculated engineering quantity is greater than the preset deviation threshold; the deviation value between the design engineering quantity and the calculated engineering quantity is less than or equal to the preset deviation threshold can represent that the deviation value between the engineering quantity of each first granularity in the design engineering quantity and the engineering quantity of the corresponding first granularity in the calculated engineering quantity is less than or equal to the preset deviation threshold.

[0059] Specifically, the three-dimensional design model can be adjusted based on the comparison result: based on each comparison record in the comparison result, determine the sign of the deviation value in the comparison record, determine whether to increase or decrease the engineering quantity of the model component corresponding to the deviation value in the three-dimensional design model based on the sign, and at the same time, based on the engineering quantity corresponding to the deviation value in the calculated engineering quantity recorded in the comparison record, determine the adjustment amplitude of the engineering quantity of the model component corresponding to the deviation value in the three-dimensional design model.

[0060] The purpose of the deviation value carrying a positive or negative sign is that through the sign, it can be clearly known whether the design engineering quantity is more than the calculated engineering quantity or the calculated engineering quantity is more than the design engineering quantity, so that when adjusting the three-dimensional design model, it can be determined whether to decrease or increase the corresponding engineering quantity based on the sign of the deviation value.

[0061] In this embodiment, after the new project calculation is completed, the reference quantities of the same type of project are called from the query library (such as the main transformer quantity of a new 500kV substation, the number and capacity of the main transformer of the historical project of the same scale are referred to); the warning deviation range is set, if the quantity of the new project deviates from the reference quantity by more than the deviation range (such as the number of the main transformer of the new project is 20% more than the reference value), the warning prompt is popped up on the user interface through the "event notification mechanism" of the BIM software, the deviation component, the deviation proportion and the reference engineering information are displayed, which assists the designer to check and adjust.

[0062] The implementation steps of the present application will be described in detail below Figure 2 And taking a 500kV extra-high voltage substation project as an example, the implementation steps of the present application are described in detail: (1) Model information standardization: a three-dimensional design model information standardization system is constructed, and the classification, attributes and pipeline integration of the model components are uniformly specified.

[0063] Classification standardization: create a "500kV substation model" in the BIM software (such as Guanglianda GDMP platform), divide the specialties according to "civil engineering-electrical engineering-water supply and drainage", divide the electrical specialty into "main transformer system-switching equipment system-grounding system", and define the "500kV oil-immersed transformer" subcategory under the main transformer system; Information supplement: add shared parameters "rated capacity (1000MVA), insulation method (oil-immersed), installation method (indoor)" to "500kV oil-immersed transformer", and add parameters "cross-sectional area (240 square millimeters), span (30 meters)" to "240 square millimeter soft conductor"; Pipeline optimization: fuse the cable bridge model of the electrical specialty and the beam model of the structure specialty, detect 3 bridge and beam collisions, adjust the bridge elevation from 3.5 meters to 4.0 meters to avoid conflicts.

[0064] (2) Quantity calculation: based on the professional characteristics of the extra-high voltage power transmission and transformation project, develop type-specific measurement rules to adapt the measurement units and calculation logic of different components; based on the standardized model and the measurement rules, perform the quantity calculation of the civil engineering, the substation / converter station and the power transmission project, and write the results back to the model.

[0065] Number measurement: select "500kV oil-immersed transformer", count the number as 2, and match the list item "transformer installation 500kV 1000MVA"; Length measurement: analyze the lofting curve length of "240 square millimeter soft conductor", the single length is 30 meters, there are 100 pieces in total, the total length is 3km, and the matching quota item is "soft conductor erection 240 square millimeters"; Volume measurement: calculate the main transformer basic volume, the basic size is 6m*4m*2m, deduct the volume of anchor bolt hole (0.1 cubic meters), the final volume is 47.9 cubic meters, and the concrete grade C30 matching list items are matched.

[0066] (3) Early warning verification: establish a reference engineering quantity query library to realize the comparison of engineering quantities between new projects and historical projects and trigger abnormal early warning.

[0067] The main transformer engineering quantity (2 sets of 1000MVA) of the "2022 certain 500kV substation" is called from the reference query library, the number of main transformers of the new project is consistent, and no early warning is triggered; The wire engineering quantity of the new project is 3km, the reference project is 2.5km, the deviation is 20%, which triggers early warning, and verification finds that the span of the new project is adjusted to 30m (the reference project is 25m), and after adjusting the span to 25m, the engineering quantity is reduced to 2.5km, and the deviation is eliminated.

[0068] The present application establishes a "classification-attribute-pipeline" three-level standardized scheme for the professional characteristics of UHV power transmission and transformation projects, solves the design and cost information fault problem, and ensures that the model can be directly used for measurement; based on the difference of component measurement units, the calculation logic including geometric analysis, Boolean operation and parameter correlation is developed to adapt to the diversified measurement needs of UHV engineering electrical and civil components; by building a historical engineering reference library, automatic comparison between new projects and historical data is realized, early warning is triggered based on threshold, engineering quantity abnormality is controlled in the design stage, and subsequent changes are reduced. In terms of efficiency: without BIM translation, engineering quantity is calculated directly based on the design model, the process link is reduced by 50%, and the calculation time is shortened by more than half; in terms of accuracy: through model information standardization and automatic calculation, human error is avoided, and the engineering quantity calculation accuracy is much higher than that of traditional methods; in terms of professional adaptability: special measurement rules are developed for electrical equipment and power transmission components of UHV power transmission and transformation projects to solve the problem of insufficient adaptation of existing general BIM calculation software to electrical power professionals; in terms of whole-process control: integrate "design-calculation-early warning" links to realize closed-loop management of engineering quantity from calculation to abnormal adjustment, and avoid cost overruns (such as early warning mechanism to reduce cost increase caused by design changes).
