[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 It is a flow chart of a photovoltaic project cost statistics method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of statistics on the construction costs of photovoltaic projects. The method can be executed by a photovoltaic project cost statistics device, which can be implemented by software and / or hardware.

[0022] like Figure 1 As shown in the figure, the statistical method of photovoltaic project costs includes the following steps:

[0023] S110 , obtaining a target design scheme for a target photovoltaic project, and determining at least one unit to be counted according to the target design scheme.

[0024] The target photovoltaic project may be a photovoltaic project for which construction cost statistics are required. The target design scheme may be a construction design scheme corresponding to the target photovoltaic project. Exemplarily, the target design scheme may include instruments and equipment required for the construction of the target photovoltaic project, equipment installation, and other engineering projects requiring expenditures. The unit to be counted may be an engineering unit for which expenditure statistics are required. Specifically, the design units in the target design scheme may be disassembled based on the preset photovoltaic unit type, thereby obtaining a plurality of units to be counted.

[0025] S120 , for each unit to be counted, determine the unit design cost corresponding to each unit to be counted according to each unit to be counted and a reference unit cost table.

[0026] The reference unit cost table may be a reference table for determining the construction cost of the unit to be counted. The unit design cost may be the cost required to build a unit to be counted.

[0027] Specifically, the reference unit cost table may include unit prices corresponding to design units of multiple unit types. For each unit to be counted, the unit price corresponding to the unit to be counted can be matched from the reference unit cost table according to the unit type of the unit to be counted, and then the reference unit price corresponding to the unit to be counted and the number of units can be multiplied to obtain the unit design cost corresponding to the unit to be counted.

[0028] S130: Determine target project cost information of the target photovoltaic project according to the unit design costs of all units to be counted.

[0029] The target project cost information may be information for predicting the project cost corresponding to the target photovoltaic project. Specifically, the unit design costs of all units to be counted may be integrated to obtain the total cost corresponding to all units to be counted, and the total cost information corresponding to all units to be counted may be used as the target project cost information.

[0030] The technical solution provided by the embodiment of the present invention obtains the target design scheme of the target photovoltaic project, determines at least one unit to be counted according to the target design scheme; for each unit to be counted, determines the unit design cost corresponding to each unit to be counted according to each unit to be counted and the reference unit cost table; determines the target project cost information of the target photovoltaic project according to the unit design costs of all units to be counted. The technical solution of the embodiment of the present invention solves the problems of inconsistent photovoltaic project budget estimates and inaccurate project cost statistics in the prior art, and can split the design units in the photovoltaic project, and respectively count the costs corresponding to each design unit based on the reference cost standard, and then determine the total design cost of the photovoltaic project, which can improve the accuracy and efficiency of the photovoltaic project budget estimates.

[0031] Figure 2 It is a flow chart of another photovoltaic project cost statistics method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of statistics on the construction cost of photovoltaic projects. Based on the above embodiment, this embodiment further explains how to determine at least one unit to be counted according to the target design scheme; how to determine the unit design cost corresponding to each unit to be counted according to each unit to be counted and the reference unit cost table; and how to determine the target project cost information of the target photovoltaic project based on the unit design costs of all units to be counted. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0032] like Figure 2 As shown in the figure, the statistical method of photovoltaic project costs includes the following steps:

[0033] S210: Obtain a target design scheme for a target photovoltaic project, decompose design units in the target design scheme based on preset photovoltaic unit types, and use the decomposed design units as units to be counted.

[0034] Among them, the target photovoltaic project may be a photovoltaic project that requires construction cost statistics. The target design scheme may be a construction design scheme corresponding to the target photovoltaic project. Exemplarily, the target design scheme may include instruments and equipment required for the construction of the target photovoltaic project, equipment installation, and other engineering projects that require expenditures. Further, the preset photovoltaic unit type may be a preset unit type for photovoltaic engineering division. Exemplarily, the preset photovoltaic type can be divided into four parts: equipment and installation engineering costs, construction engineering costs, other costs, and basic reserve funds. The unit to be counted may be an engineering unit that requires expenditure statistics. Specifically, based on the preset photovoltaic unit type, the design units in the target design scheme can be disassembled to obtain multiple units to be counted.

[0035] For example, Figure 3 is a schematic diagram of a type of preset photovoltaic unit provided by an embodiment of the present invention, such as Figure 3 As shown in the figure, the preset photovoltaic unit type includes four parts: equipment and installation engineering costs, construction engineering costs, other costs, and basic reserve costs. Among them, the equipment and installation engineering costs include power generation equipment and installation engineering, power distribution equipment and installation engineering, control and protection equipment and installation engineering; construction engineering costs include construction engineering, step-up substation engineering, housing construction engineering, transportation engineering, and other construction engineering; other costs include project construction land fees, project construction management fees, production preparation fees, survey and design fees, and other fees; the basic reserve cost only includes the basic reserve cost.

[0036] S220 , respectively determining the unit type and unit quantity corresponding to each unit to be counted.

[0037] Among them, the unit type can be the type corresponding to the unit to be counted. In the process of disassembling the entire target design scheme, the design unit in the scheme can be matched with multiple preset photovoltaic unit types, and the matched preset photovoltaic unit type can be used as the unit type corresponding to the unit to be counted. By determining the unit type corresponding to the unit to be counted, it is convenient to subsequently determine the unit price required to build the unit to be counted. Furthermore, the number of units to be counted of the same unit type can be counted, and then the number of units corresponding to each unit to be counted can be determined. By determining the number of units corresponding to the unit to be counted, it is convenient to subsequently determine the total cost required to build the unit to be counted.

[0038] S230: Based on the unit type, match the reference unit cost corresponding to each unit to be counted from the reference unit cost table.

[0039] The reference unit cost table may be a reference table for determining the construction cost of the unit to be counted. The reference unit price cost may be the construction cost corresponding to a single unit to be counted. Specifically, the reference unit cost table may include unit prices corresponding to design units of multiple unit types. The unit price cost corresponding to the unit to be counted may be obtained by matching the unit type of the unit to be counted from the reference unit cost table, and the matched unit price cost may be used as the reference unit price cost.

[0040] Optionally, a reference unit cost table is generated, including: obtaining photovoltaic project sample information, splitting the design components in the photovoltaic project sample information based on preset photovoltaic unit types to obtain sample units; determining the sample unit cost information corresponding to each sample unit based on the cost information about the sample units in the photovoltaic project sample information and a reference cost standard; and generating a reference unit cost table based on the sample unit cost information corresponding to multiple sample units.

[0041] Among them, the photovoltaic project sample information may be preset photovoltaic project construction information. Exemplarily, the photovoltaic project sample information may include the items of expenditure in the photovoltaic project construction, as well as the expenditure of each item. The sample unit may be the design unit involved in the photovoltaic project sample information. Exemplarily, the photovoltaic unit type may be preset to split the design components in the photovoltaic project sample information, thereby obtaining multiple sample units. Further, the reference cost standard may be a reference standard for determining the cost ratio of multiple types of expenditures. In the construction process of photovoltaic projects, not all expenses are for entities, that is, there are many design units without fixed cost standards in the project construction, so it is necessary to determine the charging range corresponding to the design units without fixed cost standards based on the reference cost standard. Exemplarily, the charging range corresponding to the design units with non-fixed cost standards can be determined based on the proportion of the design unit expenditures with non-fixed cost standards and the actual costs of the design units with fixed cost standards.

[0042] The sample unit cost information may be the construction unit price corresponding to a single sample unit. For example, based on the cost information about the sample unit in the photovoltaic project sample information, the cost corresponding to each type of sample unit may be counted separately, and then the cost range of the sample unit without a fixed cost standard may be adjusted based on the reference cost standard, thereby determining the sample unit cost information corresponding to each sample unit. Finally, the sample unit cost information corresponding to all sample units may be recorded in a corresponding table to generate a reference unit cost table.

[0043] S240: Determine the unit design cost corresponding to each unit to be counted according to the reference unit price and the number of units.

[0044] The unit design fee may be the fee required to construct a unit to be counted. Specifically, for each unit to be counted, the reference unit price corresponding to the unit to be counted and the number of units may be multiplied to obtain the unit design fee corresponding to the unit to be counted.

[0045] S250, counting the unit design costs of all units to be counted, and generating a target engineering budget estimate table based on the unit design costs of all units to be counted, and using the target engineering budget estimate table as the target engineering cost information.

[0046] The target project budget table may be a statistical table of project expenses corresponding to the target photovoltaic project. Specifically, the unit design expenses of all units to be counted may be counted in a corresponding table to obtain the target project budget table.

[0047] Optionally, the unit design costs of all units to be counted are counted, and a target project estimate table is generated based on the unit design costs of all units to be counted, including: constructing multiple initial sub-project estimate tables based on a reference unit cost table; based on the unit type of the units to be counted, the unit design costs of each unit to be counted are counted in the sub-project estimate table to obtain a target sub-project estimate table; and determining the target project estimate table based on multiple initial sub-project estimate tables.

[0048] The initial sub-project budget table may be an original table without data statistics. For example, the initial sub-project budget table may include at least one of: an equipment and installation project budget table, a construction project budget table, other cost budget table, and a basic reserve budget table.

[0049] The target sub-project budget table can be a table obtained by statistically analyzing the initial sub-project budget table. Specifically, based on the unit type of the unit to be statistically analyzed, the initial sub-project budget table corresponding to each unit to be statistically analyzed is analyzed, and the unit design cost is statistically analyzed in the initial sub-project budget table corresponding to the unit to be statistically analyzed, thereby obtaining the target sub-project budget table. Furthermore, all the target sub-project budget tables can be spliced ​​and combined to obtain the target project budget table.

[0050] For example, in order to better understand the technical solution provided by the present invention, a specific embodiment is introduced below:

[0051] Step 1) Extract the preset typical design scheme, summarize and preliminarily screen the engineering budget classification items and the standards used for distributed photovoltaic projects with grid-connected voltage levels ranging from 220V to 35kV. The classification items mainly include equipment costs, construction and installation costs, other costs and basic reserve costs, among which the equipment costs include the equipment costs used in the project, and the construction and installation costs include the construction engineering costs and equipment installation costs used in the project.

[0052] Step 2) Analyze and process the summary information of step 1, and redefine the classification items of the project budget, which can be divided into four parts: equipment and installation project costs, construction project costs, other costs, and basic reserve.

[0053] Step 3) Clarify the charging basis for each item in the four major parts of the second step. If the charging basis cannot be found in the relevant national standards and regulations, the compiler can give an estimated value based on the actual operation results of previous projects and then make corrections based on the results of on-site surveys. Figure 4 It can be seen that the cost of equipment and installation projects accounts for a large proportion of the total project budget, about 75% to 85%, while the equipment costs of photovoltaic modules and inverters and the material costs of cables account for about 57% of the equipment and installation project costs. Therefore, when preparing the project budget table, engineering personnel need to pay attention to the quantity and unit price of photovoltaic modules and cables, which account for a relatively large proportion.

[0054] Step 4) Establish a one-to-one logical relationship between the distributed photovoltaic planning and design unit and the engineering budget unit to form an integrated design and cost process. When establishing a one-to-one logical relationship, the planning and design unit needs to determine the type and quantity of photovoltaic components, the type and quantity of inverters, the type and quantity of cables, the type and quantity of transformers, etc., which are the parts that account for a large proportion of the cost in the engineering budget.

[0055] Step 5) Output the engineering budget form after the integrated design and cost process according to the standard template. The standard template must include the charging basis table, equipment and installation engineering budget table, construction engineering budget table, other cost budget table, basic reserve budget table and engineering total budget table. The charging basis table can list the relevant national standards and regulations used; the equipment and installation engineering budget table can list the various equipment costs, installation costs and device material costs; the construction engineering budget table can list the names of various projects and costs, various unit prices, etc.; the other cost budget table can list the various charging bases, rates, etc.; the basic reserve budget table can list the charging bases, rates, etc., so that the review unit can have an intuitive understanding of the various charging bases and improve work efficiency.

[0056] The technical solution provided by the embodiment of the present invention obtains the power generation information of the target photovoltaic project, disassembles the design units in the target design scheme based on the preset photovoltaic unit type, and uses the disassembled design units as the units to be counted; respectively determines the unit type and unit quantity corresponding to each unit to be counted; based on the unit type, matches the reference unit price cost corresponding to each unit to be counted from the reference unit cost table; according to the reference unit price cost and the unit quantity, respectively determines the unit design cost corresponding to each unit to be counted; counts the unit design costs of all units to be counted, and generates a target project budget table based on the unit design costs of all units to be counted, and uses the target project budget table as the target project cost information. The technical solution of the embodiment of the present invention solves the problems of inconsistent photovoltaic project budget standards and inaccurate project cost statistics in the prior art, can split the design units in the photovoltaic project, count the costs corresponding to each design unit based on the reference cost standard, and then determine the total design cost of the photovoltaic project, which can improve the accuracy and efficiency of the photovoltaic project budget.
