Description

Technical Field

[0001] The present invention belongs to the technical fields of power grid investment management, power grid big data processing, power grid system prediction and evaluation, and in particular to a method and system for evaluating the coupling degree between the accounting progress and on-site construction progress of a power grid infrastructure project based on a PSQ settlement model. Background Art

[0002] According to relevant laws and regulations and the development plan of the State Grid Corporation, it is required that newly started projects be counted using the financial expenditure method, while continued projects continue to be counted using the visual progress method. After the reform, investment completion and settlement are "serial relationships" and are directly related. The financial expenditure method is used for investment completion statistics, and the statistical basis is cost accounting. The amount of project investment completed is obtained by adding up the amount of cost accounting, which is closely related to the settlement of project progress payments. The settlement of project progress payments needs to be coupled with the visual progress of the project site. At present, the existing technology lacks a coupling evaluation scheme for the accounting progress and on-site construction progress of power grid infrastructure projects. Summary of the invention

[0003] To address the gaps and deficiencies in the prior art, based on the PSQ settlement model, the present invention proposes a method and system for evaluating the coupling degree between the accounting progress and the on-site construction progress of power grid infrastructure projects, which can accurately predict the coupling degree between the accounting progress and the on-site construction progress and has strong universality and stability.

[0004] The present invention specifically adopts the following technical solutions: A coupling evaluation method for power grid infrastructure project accounting progress and on-site construction progress based on PSQ settlement model: Based on the PSQ settlement model, by evaluating the monthly accounting progress and monthly on-site progress of power grid infrastructure projects, predicting the deviation between the monthly accounting progress and the monthly on-site progress, the coupling degree of power grid infrastructure project accounting progress and engineering progress is calculated.

[0005] Furthermore, the PSQ settlement model is adopted to set the power grid infrastructure project costs to include only progress payments, completion settlement payments and warranty deposits; and the warranty period is 12 months; Among them, the progress payment settlement standard is: progress payment is paid twice, and when the on-site progress is 80% completed, the first progress payment is settled, with a maximum of 50%; when the on-site progress is 80% completed, the second progress payment can be settled, with a maximum of 80%; The settlement standard for the quality guarantee deposit is: if there are no governance issues within one year after the completion of the project, the quality guarantee deposit will be settled at 3%; The settlement standard for the final settlement payment is: after the project is completed, the contract amount minus the progress payment already paid and the retained warranty deposit is the final settlement payment, which is 17%.

[0006] Furthermore, the monthly progress of the assessed power grid infrastructure project is as follows: The progress of depositing funds is divided into 5 stages: Phase A: From the start of construction to 80% completion of the on-site progress; Phase B: From 80% to 100% completion of the on-site progress Stage C is when the on-site progress is 100% completed until the project is finalized and settled; The period from project completion settlement to payment of warranty deposit is the D stage; Pay the security deposit, which is the E stage; This will evaluate the monthly progress of each stage: Phase A: Monthly deposit progress = 0; Phase B: Monthly deposit progress = 50%; Phase C: Monthly deposit progress = 70%; Phase D: Monthly deposit progress = 97%; Phase E: Monthly deposit progress = 100%.

[0007] Furthermore, the monthly progress of the assessed power grid infrastructure project is as follows: The on-site progress is divided into two stages: the first stage is from the start of construction to 80% completion of the on-site progress; the second stage is from 80% completion of the on-site progress to 100% completion of the on-site progress; The monthly on-site progress of each phase is evaluated as follows: Phase I: Monthly on-site progress = 80% / Phase I construction period in months Phase II: Monthly on-site progress = 80% + 20% / number of months for Phase II.

[0008] Furthermore, the deviation between the predicted monthly account progress and the monthly on-site progress is specifically: Statistical construction period: Construction period = number of months of construction period in Phase I + number of months of construction period in Phase II Evaluate monthly deviation: Monthly deviation = Monthly on-site progress - Monthly account progress Evaluate coupling deviation: Coupling deviation = Evaluate coupling: Coupling = .

[0009] And, a coupling evaluation system for the accounting progress and on-site construction progress of power grid infrastructure projects based on the PSQ settlement model, based on a computer system: Includes: PSQ settlement module, account entry progress assessment module, on-site progress assessment module and coupling degree assessment module; The PSQ settlement module is used to calculate the settlement costs of power grid infrastructure project costs using the PSQ settlement model; The account entry progress evaluation module is used to evaluate the monthly account entry progress of power grid infrastructure project expenses; The on-site progress assessment module is used to assess the monthly on-site progress of power grid infrastructure projects; The coupling degree evaluation module is used to evaluate the coupling degree between the accounting progress and the engineering progress of the power grid infrastructure project.

[0010] 1. According to claim 6, a system for evaluating the coupling degree between the accounting progress and the on-site construction progress of power grid infrastructure projects based on the PSQ settlement mode, characterized in that: The PSQ settlement model stipulates that the costs of power grid infrastructure projects only include progress payments, completion settlement payments and warranty deposits; and the warranty period is 12 months; Among them, the progress payment settlement standard is: progress payment is paid twice, and when the on-site progress is 80% completed, the first progress payment is settled, with a maximum of 50%; when the on-site progress is 80% completed, the second progress payment can be settled, with a maximum of 80%; The settlement standard for the quality guarantee deposit is: if there are no governance issues within one year after the completion of the project, the quality guarantee deposit will be settled at 3%; The settlement standard for the final settlement payment is: after the project is completed, the contract amount minus the progress payment already paid and the retained warranty deposit is the final settlement payment, which is 17%.

[0011] Furthermore, the account entry progress evaluation module divides the account entry progress into five stages: Phase A: From the start of construction to 80% completion of the on-site progress; Phase B: From 80% to 100% completion of the on-site progress Stage C is when the on-site progress is 100% completed until the project is finalized and settled; The period from project completion settlement to payment of warranty deposit is the D stage; Pay the security deposit, which is the E stage; This will evaluate the monthly progress of each stage: Phase A: Monthly deposit progress = 0; Phase B: Monthly deposit progress = 50%; Phase C: Monthly deposit progress = 70%; Phase D: Monthly deposit progress = 97%; Phase E: Monthly deposit progress = 100%.

[0012] Furthermore, the on-site progress assessment module divides the on-site progress into two stages: from the start of construction to 80% completion of the on-site progress, which is stage I; from 80% completion of the on-site progress to 100% completion of the on-site progress, which is stage II; The monthly on-site progress of each phase is evaluated as follows: Phase I: Monthly on-site progress = 80% / Phase I construction period in months Phase II: Monthly on-site progress = 80% + 20% / number of months for Phase II.

[0013] Furthermore, the coupling evaluation module includes the following calculations: Statistical construction period: Construction period = number of months of construction period in Phase I + number of months of construction period in Phase II Evaluate monthly deviation: Monthly deviation = Monthly on-site progress - Monthly account progress Evaluate coupling deviation: Coupling deviation = Evaluate coupling: Coupling = .

[0014] An electronic device comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps of a method for evaluating the coupling degree between the accounting progress and the on-site construction progress of a power grid infrastructure project based on the PSQ settlement mode are implemented as described above.
