[0048] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0054] The working principle and beneficial effects of the above technical solution are:

[0055] For the offshore wind power project budget template, the sub-projects are divided into: construction auxiliary projects, equipment and installation projects, construction projects, and other expenses. The construction project table is used to store the project divisions in the "Compilation Regulations". The table header row attribute fields are: code, project name, project characteristics, unit, quantity calculation, quantity, unit price, unit price number, remarks, project category, mark color, index unit price, similar unit price range, etc. The calculation of the construction project budget cost is the core link of project planning and budget management. It ensures the accurate estimation of project costs, provides a scientific basis for project investment decisions, fund raising, cost control and contract negotiations, and helps to optimize resource allocation, reduce financial risks, improve project economic benefits, and ensure the smooth progress of project construction.

[0056] (1) Equipment costs

[0057] The main equipment fee is calculated by multiplying the design engineering quantity by the original price of the equipment, and taking into account the comprehensive transportation and miscellaneous expenses. Among them, the original price of the equipment is calculated according to the following standards: the wind turbine equipment adopts the domestic whole machine procurement method, and the price at the construction site is 3,400 yuan / kW with reference to the tendered price and comprehensive consideration. The tower is produced domestically, and the price at the construction site is 10,000 yuan / t. The comprehensive transportation and miscellaneous expenses are calculated at 0.6% of the original price of the equipment, including 0.1% for unloading fees and 0.5% for procurement and storage fees.

[0058] The unit price of other equipment is calculated with reference to similar projects and market prices. Comprehensive transportation and miscellaneous expenses are calculated at 4.92% of the original price of the equipment, including 4.0% for equipment transportation and miscellaneous expenses, 0.4% for equipment transportation insurance, and 0.5% for equipment purchase and storage fees.

[0059] (2) Installation fee

[0060] It is calculated by multiplying the design engineering quantity by the installation unit price.

[0061] The budget calculation of power plant equipment and installation projects is a complex process involving multiple aspects of costs. The following are common budget calculation formulas:

[0062] 1. Equipment costs

[0063] Equipment costs include all necessary equipment purchase costs, such as wind turbines, transformers, switch station equipment, submarine cables, etc.

[0064] Equipment cost = ∑ (equipment unit price × equipment quantity)

[0065] 2. Installation costs

[0066] Installation costs include equipment installation, debugging, testing and other costs.

[0067] Installation cost = ∑ (installation unit price × number of equipment)

[0068] 3. Shipping costs

[0069] Transportation costs include the cost of transporting equipment from the manufacturing plant to the construction site.

[0070] Transportation cost = ∑ (transportation unit price × equipment weight or volume)

[0071] 4. Civil construction costs

[0072] Civil engineering costs include infrastructure, road construction, substation construction, etc.

[0073] Civil engineering cost = ∑ (unit price of civil engineering × quantity of civil engineering work)

[0074] 5. Survey and design fees

[0075] The survey and design costs include geological survey, engineering design, drawing production and other costs.

[0076] Survey and design fee = total project investment × survey and design fee rate

[0077] 6. Project construction management expenses

[0078] Project construction management costs include project management, supervision, consulting and other fees.

[0079] Project construction management fee = total project investment × project construction management fee rate

[0080] 7. Production preparation costs

[0081] Production preparation costs include costs such as personnel training and production startup.

[0082] Production preparation cost = total project investment × production preparation rate

[0083] 8. Other expenses

[0084] Other expenses include temporary facility fees, insurance premiums, unforeseen expenses, etc.

[0085] Other expenses = ∑(various expenses)

[0086] 9. Taxes

[0087] Taxes and fees include value-added tax, urban maintenance and construction tax, education surcharge, etc.

[0088] Taxes = ∑ (various expenses × tax rate)

[0089] 10. Total Cost

[0090] Sum up the above expenses to get the total cost.

[0091] Total cost = equipment cost + installation cost + transportation cost + civil engineering cost + survey and design cost + project construction management cost + production preparation cost + other costs + taxes

[0092] Calculation process for equipment and installation project budget of offshore power generation projects

[0093] Equipment and installation project budget = power plant equipment and installation project budget + booster energy storage station equipment and installation project budget + other equipment and installation project budget

[0094] The required number of equipment, equipment cost, installation project cost, material cost for equipment supplied by Party A, and comprehensive transportation and miscellaneous expenses are known. The number of equipment, equipment cost, installation cost, and comprehensive transportation and miscellaneous expenses are defined.

[0095] Known formula

[0096] Power plant equipment and installation engineering costs = (N1×C1+N1×(I1+M1)+T1)+(N2×C2+N2×

[0097] (I2+M2)+T2)+(N3×C3+N3×(I3+M3)+T3)+(N4×C4+N4×(I4+M4)+T4)+(N5×C5+N5×(I5+M5)+T5)

[0098] in:

[0124] By putting the calculated power plant equipment and installation project budget, collector line equipment and installation project budget, booster energy storage station equipment and installation project budget, and other equipment and installation project budget costs into the formula, we can finally get the estimated cost of offshore power generation project equipment and installation project.

[0125] For the above-mentioned budget estimation process, by listing various items of the project, it is impossible to conduct targeted analysis during the implementation process. On this basis, the present invention proposes a construction engineering budget estimation analysis method for offshore wind power engineering projects. First, a visualization model is constructed based on the planning data of the offshore wind power engineering project; the specific effect of the project can be intuitively seen through the visualization model; then, initial budget estimation analysis data is generated based on the visualization model; the initial budget estimation analysis data is basically equivalent to the above-mentioned budget estimation process, but it should be noted that in order to facilitate subsequent management, each budget item of the budget estimation data needs to be associated with a model component or a divided unit of the visualization model. During the project construction process, the project construction data is obtained in real time, and the visualization model is updated based on the project construction data, and the initial budget estimation analysis data is updated based on the project construction data and the visualization model; through the real-time update of the project construction data, the initial budget estimation analysis data is updated on this basis, so as to realize accurate and effective cost management throughout the process.

[0126] In order to realize the construction of a visualization model, in one embodiment, a visualization model is constructed based on the planning data of an offshore wind power project, including:

[0127] According to the pre-configured data extraction templates of each model component and the data extraction rules corresponding to each data extraction template, the planning data is extracted to obtain the corresponding parameter data of each model component;

[0128] According to the parameter data corresponding to each model component, the corresponding model component is retrieved from the pre-configured model library;

[0129] The retrieved model components are spliced ​​together to form a visual model.

[0130] The construction of the visualization model provided in this embodiment is based on a pre-configured model library, which stores various model components of the construction project under construction. The model components may specifically include: model components corresponding to wind turbines, model components corresponding to unit transformers, model components corresponding to towers, model components corresponding to grounding equipment, etc.; the planning data is extracted to extract the model components covered by the construction project, and then the components are spliced ​​to form a visualization model; the visualization model is essentially a three-dimensional model corresponding to the project; in order to facilitate the generation of the visualization model, when the planning data is formed, a part of the planning data clearly states the number of objects (unit transformers, wind turbines, etc.) of the construction project and the corresponding parameters (models, power, dimensions, etc.), as well as the connections between the objects; the models retrieved are spliced ​​according to the connection relationship stated in the planning data to ensure the accuracy of the formed visualization model.

[0131] In order to realize accurate generation of initial budget analysis data, in one embodiment, generating initial budget analysis data according to a visualization model includes:

[0132] According to the pre-configured model segmentation rules, the visualization model is segmented to obtain multiple budget units; for example, the indivisible parts (wind turbines, transformers, etc., which are finished units that can be directly installed and wired) are segmented as a whole into a budget unit, and the divisible parts (towers, etc.) can be segmented according to the equal-area segmentation method or according to the smallest units such as beams and rods; the equal-area segmentation method treats this area as a whole;

[0133] According to the pre-configured budget rules corresponding to each budget unit, the initial analysis data corresponding to each budget unit is generated; each budget unit is configured with its corresponding budget rule, and the budget rule is the quantification of the equipment cost, equipment installation cost, device material cost, comprehensive transportation and miscellaneous cost, etc. corresponding to a budget unit;

[0134] The initial analysis data corresponding to each budget unit is collected to obtain the initial budget analysis data. That is, the initial analysis data of each budget unit is integrated, and other related expenses (civil construction costs + survey and design costs + project construction management costs + production preparation costs + other costs + taxes, which can be obtained from planning data or calculated according to pre-configured calculation formulas) are added on this basis to form the initial budget analysis data.

[0135] In order to achieve accurate model update, in one embodiment, updating the visual model according to the project construction data includes:

[0136] Perform finite element segmentation on the visualization model and divide the visualization model into various finite element units. When performing finite element segmentation, you can refer to the segmentation of the budget unit, that is, the indivisible parts (wind turbines, unit transformers, etc., which are finished units that can be directly installed and wired) can be divided into a finite element unit as a whole. For the divisible parts (towers, etc.), they can be divided according to the equal area segmentation method or according to the smallest units such as beams and rods. The equal area segmentation method is to treat this area as a whole as a finite element unit. When performing the regional segmentation method, the parameters with material details in the segmented area are counted as the characterization parameters of the finite element unit.

[0137] Determine the status of each finite element based on the project construction data; the status includes: completed, under construction, and not under construction;

[0138] Fill the completed finite element units. There are two representations of finite element units: one is unfilled, which uses a frame to construct the outline of the finite element to mark it; the other is filled, that is, the area between the frames is filled with solid color;

[0139] This embodiment divides the model into finite element units and uses the filling of the finite element units to indicate the completion of the construction, so that the construction effect can be seen intuitively and it is more convenient to update the initial budget analysis data.

[0140] In order to update the model to the initial budget analysis data, in one embodiment, the initial budget analysis data is updated according to the project construction data and the visualization model, including:

[0141] Based on the project construction data corresponding to the completed finite element units, actual cost accounting is performed to update the data corresponding to the finite element units in the initial budget analysis data;

[0142] Based on the actual cost of the first related item belonging to the pre-configured associated cost item in the project construction data, the actual cost of other second related items in the initial budget analysis data is updated;

[0143] The data of the same unimplemented budget items in the initial budget analysis data are updated based on the actual costs of the budget items that have been incurred in the project construction data.

[0144] When the initial budget analysis data is updated, it mainly includes updating the data of the finite element units that have been completed in the initial budget analysis data. Construction completion means that the project represented by the finite element unit is completed and the cost has been actually incurred. In essence, it is to update the estimated data in the initial budget analysis data to the actual cost; then update the associated costs, such as taxes and fees related to the total cost. In addition, there is a ratio between the installation fee of the configured wind turbine and the installation fee of the unit transformer, which is A. When the installation fee of the wind turbine is the corresponding first relationship item, the installation fee of the unit transformer is the second relationship item. When the installation fee of the wind turbine is recorded in the construction data and the installation fee of the unit transformer is not recorded, the associated cost items can be used to supplement the data; finally, the actual costs that have not been issued are updated and corrected based on the actual costs that have been issued, and further updated and corrected based on the actual costs incurred by this construction project itself, so that the budget analysis data is closer and closer to reality, and it has more analytical research value.

[0145] In one embodiment, the data of the same unimplemented budget items in the initial budget analysis data are updated based on the actual costs of the budget items that have been generated in the project construction data, including:

[0146] Group the actual costs of the budget items that have been incurred by finite element units and match them with the corresponding filled finite element units;

[0147] According to the characterization parameters of the filled finite element unit and the unfilled finite element unit, the unfilled finite element unit is associated with the filled finite element unit and an association coefficient set is determined;

[0148] Based on the determined correlation coefficient and the actual cost in the group corresponding to the filled finite element unit, the estimated data corresponding to the associated unfilled finite element unit is updated;

[0149] Among them, each data in the correlation coefficient set is the inverse of the ratio between the actual cost of each generated budget item in the group and the corresponding associated ungenerated budget data; when updating, the actual cost generated can be directly multiplied by the corresponding data in the correlation coefficient set to update the budget data with the obtained data;

[0150] According to the characterization parameters of the filled finite element unit and the unfilled finite element unit, the unfilled finite element unit and the filled finite element unit are associated and the association coefficient set is determined, including:

[0151] When the filled finite element unit and the unfilled finite element unit have the same number and consistent characterization parameters, the two are associated; at this time, the association may appear one-to-many, many-to-one, or many-to-many.

[0152] When the same unfilled finite element unit is associated with multiple filled finite element units, in order to facilitate analysis and processing, one way is to further narrow the association relationship, build a feature set of finite element units according to the narrowing requirement, and then further narrow the association relationship based on the feature set; wherein the steps of constructing the feature set are as follows: the parameter data representing the parameters are arranged in sequence and the coordinate data representing the position of the finite element unit in the model and the time data of the filling time are added after the arranged data to form a feature set; wherein the time planned by the unfilled finite element unit according to the construction progress plan is used as the time data of the filling time. The narrowing method is to calculate the similarity between the feature set of the unfilled finite element unit and the feature set of the filled finite element unit, and take the filled finite element unit with the largest similarity as the final association item with the unfilled finite element unit; wherein the similarity can be calculated by the cosine similarity calculation method.

[0153] At this time, the construction of the association coefficient set is to configure different relationship conversion tables for each table parameter between each associated finite element unit; when determining, according to the characterization parameter, or the characterization parameter and the position parameter (the position parameter is the position of the filled finite element unit in the model and the position of the unfilled finite element unit in the model), query the relationship conversion table to obtain the corresponding value;

[0154] To further improve the accuracy of the update, the construction engineering budget analysis for offshore wind power projects also includes:

[0155] When updating the estimated data corresponding to the filled finite element unit according to the associated filled finite element unit, determining whether the estimated data corresponding to the filled finite element unit has been updated in an associated manner, and when updated in an associated manner, determining the number of associated updates and the update value each time;

[0156] Determine the coefficient of variance between each updated value and the actual cost (the ratio between the difference between the actual cost and the updated value). Variance determination shall be made for each budget item.

[0157] The final correction factor is determined according to the following formula:

[0158]

[0159] In the formula, C i is the difference coefficient of the last ith update, μ iThe weight of the last ith update is determined by querying the preset weight coefficient table according to the number of updates, and X is the correction coefficient;

[0160] The estimated data of the corresponding estimated items are corrected according to the correction coefficient. The corrected data is the original data plus the product of the correction coefficient and the original data.

[0161] The present invention provides a construction engineering budget analysis system for offshore wind power engineering projects, such as Figure 2 As shown, it includes: a construction module 1, a generation module 2 and an update module 3; wherein the construction module 1 constructs a visualization model based on the planning data of the offshore wind power project; the generation module 2 generates initial budget analysis data based on the visualization model; the update module 3 obtains the project construction data in real time during the project construction process, updates the visualization model based on the project construction data, and updates the initial budget analysis data based on the project construction data and the visualization model.
