DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0018] like Figure 1 As shown, the present invention provides a method for constructing an investment plan preparation model, the method comprising the following steps: Step 100: Obtain data from the feasibility study stage and preliminary design stage of a power grid infrastructure project.

[0019] Specifically, the data sources available to the system at each stage of the power grid infrastructure project execution are different. For the feasibility study stage, the data available mainly include engineering costs, while for the preliminary design stage, the data available include project budget, project construction start time, and completion rate of progress nodes.

[0020] For example, as shown in Table 1, the engineering costs in the feasibility study stage for a substation project mainly include four costs, namely, construction costs, equipment costs, first installation costs, and first other costs.

[0021]

[0022] For another example, as shown in Table 2, the engineering costs in the feasibility study stage for overhead line engineering projects mainly include the second installation fee and the second other fees.

[0023]

[0024] For the initial design phase of substation projects and overhead line projects, the system can obtain data including project budget, project construction start time, and completion ratio of progress nodes.

[0025] Step 101: Based on the data, the investment plan is compiled according to the feasibility study stage and the preliminary design stage, and an investment plan compilation model is constructed; Among them, the investment plan preparation method in the feasibility study stage further includes: According to the reasonable construction period and planned progress nodes of the power grid infrastructure project, by inputting the start time, the planned completion time of each progress node is formed, and the planned progress nodes are updated; Based on the updated progress nodes, according to the upper limit of the investment completion ratio of the project cost in the stages of commencement, commissioning, project settlement and final settlement, the estimated investment of the corresponding milestone nodes is allocated on a monthly basis, a monthly investment plan preparation model is constructed, and the annual investment plan is summarized; The investment planning method at the initial stage further includes: Set the proportion of investment allocated for the estimated cost corresponding to the project schedule node in the stages of commencement, commissioning, project settlement, and final settlement; decompose the integrated node construction period on a monthly basis, and simultaneously allocate the estimated investment of the corresponding node on a monthly basis, build a monthly investment plan preparation model, and summarize the annual investment plan.

[0026] Specifically, for the substation investment plan preparation model in the feasibility study stage: According to the reasonable construction period of conventional new power transmission and transformation projects stipulated by the State Grid (the reasonable construction period of substation milestones in the feasibility study stage is as follows: Figure 2 As shown in the figure, the planned progress nodes of the substation are obtained from the system. By inputting the start time, the planned completion time of each progress node is formed. Considering factors such as process requirements, external environment and equipment supply, each project can be adjusted according to its own conditions.

[0027] The progress of substation construction in the feasibility study stage is divided into civil construction, main equipment arrival, equipment installation and commissioning. The substation data source that the system can obtain in the feasibility study stage mainly includes four expenses: the four expenses are shown in Table 1 in step 100.

[0028] According to the reasonable construction period of conventional new transmission and transformation projects stipulated by the State Grid, taking into account the construction sequence of the project, according to the upper limit of the investment completion ratio of the four expenses in the stages of commencement, commissioning, project settlement, and final settlement: the guideline for the investment completion ratio of substations in the feasibility study stage is as follows: Figure 3 As shown, The estimated investment of the corresponding milestone nodes is allocated monthly, and a monthly investment plan preparation model is designed to summarize the annual investment plan. The model for preparing the substation investment plan in the feasibility study stage is as follows: Figure 4 shown.

[0029] For the initial stage substation investment plan preparation model: In the initial design stage, the system can obtain data sources including project budget, project construction start time, progress node completion ratio, etc. The budget costs corresponding to different types of project schedule nodes are as follows: Figure 5 shown.

[0030] The characteristics of power transmission and transformation projects are complex and changeable. For example, the names of 13 progress nodes such as substation civil engineering and power distribution device system construction and structures, outdoor water supply and drainage and rainwater and sewage system construction and structures are diverse in the budget estimates, and cannot be accurately matched. The budget estimates corresponding to the five progress nodes such as station area buildings and site-related projects, power distribution device buildings, and auxiliary production buildings after integration can be automatically parsed and accurately matched through the budget estimate table.

[0031] According to the data sources available in the system, in the initial design phase, the civil engineering part of the substation is subdivided into station buildings and site-related projects, main production buildings, distribution device buildings, auxiliary production buildings, and fire protection systems; the electrical part of the substation is subdivided into primary electrical equipment installation, secondary electrical equipment installation, cables, and grounding.

[0032] Through the budget analysis, the cost of construction engineering and installation engineering can be obtained. With reference to the guidance line algorithm of 35 kV and above physical engineering quantity, the investment proportion of each cost in the stages of construction, commissioning, project settlement, and final settlement can be set. The guidance line of the investment completion ratio of the substation in the initial stage is as follows: Figure 6 shown.

[0033] The node construction period after monthly decomposition and integration is simultaneously allocated on a monthly basis for the corresponding node budget investment, and a monthly investment plan preparation model is constructed to summarize the annual investment plan. Figure 7 shown.

By inputting the start time, the planned completion time of each progress node is formed. Considering factors such as process requirements, external environment and equipment supply, each project can be adjusted according to its own conditions.

[0035] The construction progress of overhead lines is divided into foundation construction, tower assembly, and line laying construction. The data sources of overhead line projects that can be obtained by the system during the feasibility study phase mainly include installation fees and other fees.

[0036] Considering the construction sequence of the project, the upper limit of the investment completion ratio of the overhead line project cost in the stages of commencement, commissioning, project settlement, and final settlement is as follows: (The guideline for the investment completion ratio of the overhead line project in the feasibility study stage is as follows: Fig. 9 shown) The estimated investment of the corresponding milestone nodes is allocated monthly, and a monthly investment plan preparation model is designed to summarize the annual investment plan. The investment plan preparation model for overhead line projects in the feasibility study stage is as follows: Fig.10 shown.

[0037] A model for compiling investment plans for overhead line projects in the initial design phase In the initial design stage, the system can obtain data sources including project budget, project construction start time, progress node completion ratio, etc. The budget costs corresponding to different types of project schedule nodes are as follows: Fig.11 As shown: Refer to the algorithm of the physical engineering quantity guidance line for 35 kV and above line projects, set the investment proportions for line foundation, tower assembly, line stringing, etc. in the stages of commencement, commissioning, project settlement, and final settlement. Among them, the investment completion ratio guidance line for overhead line projects in the initial stage is as follows: Fig.12 shown.
