Description

Technical Field

[0001] This application relates to the technical field of project management, and in particular to a method, device, equipment and storage medium for monitoring power grid infrastructure projects. Background Technology

[0002] In today's society, electricity, as a basic energy source, plays a vital supporting role in economic and social development. As a fundamental guarantee for power supply, the scale and number of power grid infrastructure projects are constantly expanding with the continuous economic growth and the acceleration of urbanization.

[0003] Under the traditional management model, various data for power grid infrastructure projects are scattered and stored in different departments and systems. For example, investment data is mainly managed by the planning department and stored in a dedicated investment management system; material supply data is the responsibility of the materials department and recorded on the materials management platform; and construction progress data is held by the construction department and usually exists in the form of paper reports or simple spreadsheets. The lack of an effective data sharing mechanism between departments leads to the inability to circulate and integrate information in a timely manner, forming information silos.

[0004] This phenomenon of data dispersion and information silos brings many inconveniences to project management. Project managers find it difficult to obtain comprehensive and accurate project information, and are unable to monitor and analyze the overall progress of the project in real time, resulting in incomplete decision-making. Summary of the Invention

[0005] In order to monitor and analyze the overall progress of the project in real time, this application provides a method, device, equipment and storage medium for monitoring power grid infrastructure projects.

[0006] Firstly, this application provides a method for monitoring power grid infrastructure projects, employing the following technical solution: A method for monitoring power grid infrastructure projects, comprising: Obtain construction information from power grid infrastructure projects. The construction information includes information on multiple individual projects, and the information on individual projects includes information on sub-projects, the current construction time of each sub-project, and the preset time percentage of each sub-project. The completion time percentage of each of the sub-projects is determined based on the current construction time and the preset construction time. The construction progress value of each individual project is calculated based on the completion time percentage of the sub-projects and the corresponding preset time percentage. The overall progress value of the power grid infrastructure project is calculated based on the construction progress value of each individual project and the corresponding proportion of the estimated budget of each individual project. Calculate the current theoretical completion value based on the overall progress value and the estimated total investment; The deviation value is calculated based on the current theoretical completion value and the actual investment completion value. The deviation value is compared with the preset value corresponding to the current construction time to obtain the comparison result, and a prompt message is determined based on the comparison result.

[0007] By adopting the above technical solution, the current construction time of each milestone node and the completion time ratio of each individual project are calculated using the milestone node information, sub-project information, and itemized project information in the individual project information, as well as the preset time ratio of the sub-project information. This allows for the calculation of the construction progress value of the individual project. The overall progress value of the power grid infrastructure project is then determined based on the construction progress value of the individual project, thus yielding the current completion value. The deviation value is calculated by comparing the current theoretical completion value with the actual investment completion value, and compared with a preset threshold to obtain the comparison result. This enables real-time monitoring and comprehensive analysis of the overall project progress, improving the accuracy of analysis and decision-making.

[0008] Optionally, multiple historical infrastructure projects of the same type as the power grid infrastructure project can be obtained; Extract the information to be used that matches the current construction time from the historical construction information of the historical infrastructure project. The information to be used includes historical deviation values. The preset value is determined based on Monte Carlo simulation and the information to be used.

[0009] By adopting the above technical solutions, by screening historical projects of the same type as the current power grid infrastructure projects, the correlation between historical data and the construction environment and process flow of the current project is ensured. By screening historical deviation values ​​that match the current construction time, the preset values ​​are ensured to reflect the typical deviation range of the current stage. Through Monte Carlo simulation, the probability interval of the preset values ​​is generated based on the probability distribution of historical deviation values, thereby improving the applicability of the preset values.

[0010] Optionally, before comparing the deviation value with a preset value corresponding to the current construction time, the method further includes: Determine the construction time period corresponding to the current construction time and the start construction time; Obtain the weather information for the construction period and the comparison results; Calculate the first calculated value corresponding to the weather information and the second calculated value corresponding to the comparison result; The adjustment coefficient is determined based on the first calculated value and the second calculated value; The preset value is adjusted based on the adjustment coefficient, and the deviation value is compared with the adjusted preset value.

[0011] By adopting the above technical solution, the current construction period is determined, and the weather information and historical comparison results for the current construction period are obtained to achieve phased adjustments. The specific weather information for the construction period is obtained and converted into a first calculated value to quantify the impact of weather. The historical comparison results for the construction period are obtained and converted into a second calculated value to achieve linkage between historical and real-time data. The adjustment coefficient is calculated using the first and second calculated values ​​to achieve quantitative integration of multi-dimensional factors and improve the accuracy of preset value adjustments.

[0012] Optionally, calculating the first calculated value corresponding to the weather information and the second calculated value corresponding to the comparison result includes: based on Calculate the first calculated value; based on Calculate the second calculated value; in, For the first calculated value, This is the second calculated value. This refers to the actual number of hours the disaster lasted. Based on the base duration, As a correction factor, This is the deviation value. This is the current preset value; Determining the adjustment coefficient based on the first calculated value and the second calculated value includes: based on Calculate the adjustment factor; Where β is the adjustment coefficient, γ is the risk sensitivity factor, and a is the directional weight index.

[0013] Optionally, the construction information also includes information on various time nodes of the power grid infrastructure project; after obtaining the construction information in the power grid infrastructure project, it further includes: In the event of a time sequence problem in the project commencement time, project commissioning time, project settlement time, and project final settlement time, at least one of the following times will be corrected based on preset rules: project commencement time, project commissioning time, project settlement time, and project final settlement time. In cases where the project start time and project commissioning time do not match, the project start time and project commissioning time will be corrected based on preset rules; In the event of a mismatch between the project commissioning time and the project settlement time, the project commissioning time and the project settlement time will be corrected based on preset rules; In cases where the project settlement time and the project final account time do not match, the project settlement time and the project final account time will be corrected based on preset rules.

[0014] By adopting the above technical solution, when there are timing issues in the time nodes of project approval and filing, material bidding, commencement, settlement, final account, and commissioning, resulting in data inconsistencies, the system can monitor and automatically correct time node conflicts in real time, thereby reducing project delays or resource waste caused by time mismatches.

[0015] Optionally, an alarm message may be generated if the project scale does not match the project scale information and individual project scale information in the preliminary design approval document. An alarm will be generated if the project commencement scale does not match the project scale information and individual project scale information in the project commencement report. An alarm message is generated if the project's production scale does not match the production scale stated in the project completion report.

[0016] By adopting the above technical solutions, and by comparing the scale information in the preliminary design approval, commencement report, and completion report, problematic scale information can be identified in a timely manner and alerts can be issued, thereby reducing decision-making biases caused by information silos.

[0017] Optional acquisition of construction scale information and information on various time nodes of power grid infrastructure projects includes: Based on large model text parsing technology, the construction scale information and the information of each time node of the power grid infrastructure project are extracted from the relevant documents of the power grid infrastructure project.

[0018] Secondly, this application provides a monitoring device for power grid infrastructure projects, which adopts the following technical solution: A monitoring device for power grid infrastructure projects, comprising: The acquisition module is used to acquire construction information in power grid infrastructure projects. The construction information includes information on multiple individual projects, and the information on individual projects includes information on sub-projects, the current construction time of each sub-project, and the preset time percentage of each sub-project. The determination module is used to determine the completion time percentage of each of the sub-projects based on the current construction time and the preset construction time. The first calculation module is used to calculate the construction progress value of each milestone node based on the completion time percentage of the sub-project and the corresponding preset time percentage. The second calculation module is used to calculate the construction progress value of each individual project based on the completion time percentage of the milestone node and the corresponding preset time percentage. The third calculation module is used to calculate the overall progress value of the power grid infrastructure project based on the construction progress value of each individual project and the corresponding proportion of the estimated budget of the individual project. The fourth calculation module is used to calculate the current theoretical completion value based on the overall progress value and the estimated total investment. The fifth calculation module is used to calculate the deviation value based on the current theoretical completion value and the actual investment completion value; The comparison module is used to compare the deviation value with a preset value corresponding to the current construction time, obtain a comparison result, and determine a prompt message based on the comparison result.

[0019] By adopting the above technical solution, the completion time percentage of each individual project is calculated by using the sub-project information of the individual project information, the current construction time of the sub-project information, and the preset time percentage of the sub-project information. This allows for the calculation of the construction progress value of each individual project. The overall progress value of the power grid infrastructure project is then determined based on the construction progress value of each individual project, thus yielding the current theoretical completion value. The deviation value is calculated by comparing the current theoretical completion value with the actual investment completion value and compared with a preset threshold to obtain the comparison result. This enables real-time monitoring and comprehensive analysis of the overall progress of the project, improving the accuracy of analysis and decision-making.

[0031] like Figure 1 As shown, a monitoring method for power grid infrastructure projects is described in the following main process flow (steps S101 to S107): Step S101: Obtain construction information in the power grid infrastructure project. The construction information includes information on multiple individual projects. The information on individual projects includes information on sub-projects, the current construction time of each sub-project, and the preset time percentage of each sub-project. In this embodiment, construction information in power grid infrastructure projects is obtained through an infrastructure management system, a PMS system, and an IoT terminal. The infrastructure management system obtains structured project plan data, including project codes and milestone information, through a standardized API interface. The PMS system uses dynamic webpage parsing technology combined with OCR recognition to capture semi-structured progress reports and automatically extracts key time nodes. The IoT terminal receives real-time sensor data from the construction site based on the MQTT protocol, including equipment activation time and environmental monitoring data.

[0032] In this embodiment, the information on individual projects includes, but is not limited to, substation projects, cable projects, and overhead line projects.

Milestones for cable projects include, but are not limited to, cable ducts, cable laying, etc. Cable commissioning and acceptance defect elimination, including cable channel sub-project information such as earthwork, cable tunnel construction, demolition (reusable), and demolition (non-reusable); cable laying sub-project information such as cable bridges, bracket fabrication and installation, cable laying, cable accessories, and cable fireproofing; cable commissioning sub-project information such as commissioning and testing, cable monitoring (control) system, demolition (reusable), and demolition (non-reusable); acceptance defect elimination sub-project information such as acceptance defect elimination; overhead line project milestones including line foundation construction, line tower construction, and line stringing construction, including line foundation construction sub-project information such as foundation excavation and foundation pouring; line tower construction sub-project information including but not limited to auxiliary works, pole and tower works, and grounding works; line stringing construction sub-project information including but not limited to stringing works, accessory installation works, auxiliary works, communication line works, and demolition works.

[0033] In this embodiment, construction information is collected by an RPA robot. Based on the individual project code, the construction information of individual projects is automatically collected from the infrastructure management system, PMS system and IoT terminal, and then summarized to the corresponding power grid infrastructure project.

[0034] This application also includes the verification of construction scale information and information on various time nodes of the power grid infrastructure project. The acquisition of construction scale information and information on various time nodes of the power grid infrastructure project includes: extracting construction scale information and information on various time nodes of the power grid infrastructure project from relevant documents based on large model text parsing technology.

[0035] Verification of various time nodes for power grid infrastructure projects includes: correcting at least one of the following times based on preset rules when there are time sequence issues in the project commencement, commissioning, settlement, and final settlement times; correcting both the commencement and commissioning times based on preset rules when they do not match; correcting both the commissioning and settlement times based on preset rules when they do not match; and correcting both the settlement and final settlement times based on preset rules when they do not match.

[0036] In this embodiment, the project start time is obtained through the PMS system, the project commissioning time is obtained through the completion and acceptance report, the settlement time is determined through the settlement audit report, and the project final settlement time is obtained through the final settlement audit report.

[0037] The following is a verification and correction of information at various time points for power grid infrastructure projects: (a) Time sequence verification of project commencement time, project commissioning time, project settlement time, and project final account time.

[0038] Establish a timeline rule: Project start time < Project commissioning time < Project settlement time < Project final account time.

[0039] Verification: The four obtained time points are compared according to the rules described above. If any discrepancies are found in the time sequence, such as the settlement time being earlier than the production launch time, the process proceeds to the correction stage.

[0040] Correction: Depending on the specific circumstances and based on subsequent matching and verification rules, at least one of the following dates will be corrected: project commencement date, project commissioning date, project settlement date, and project final settlement date. For example, if the settlement date is earlier than the commissioning date, first check whether the commissioning date and the settlement date meet their respective matching rules. If not, correct the commissioning date or the settlement date according to the corresponding matching rules. If they meet the rules, then based on the actual progress of the project, combined with historical data and expert experience, make reasonable adjustments to the timeline to ensure correct timing.

[0041] (II) Verification and Correction of the Mismatch Between Project Start-up Time and Project Commissioning Time: The first construction period rule is that the commissioning time should be after the commencement time, and the interval should not be less than the reasonable construction period. According to the "Standard Construction Period Manual for Power Grid Infrastructure Projects", the reasonable construction period for 110kV line projects is 8 months.

[0042] Verification: Calculate the interval between the commissioning time and the start time. If the interval is less than the reasonable construction period, it is judged as a mismatch.

[0043] Correction: The production start time will be adjusted to the start time plus the reasonable construction period. If the actual construction period deviates from the reasonable construction period due to special reasons such as force majeure or policy adjustments, relevant supporting materials must be provided. After evaluation by the project management expert team, the reasonable construction period will be adjusted appropriately, and the production start time will be recalculated.

[0044] (III) Verification and Correction of the Mismatch between Project Commissioning Time and Project Settlement Time: The second construction period time rule: the settlement time should be after the commissioning time, and the interval should not be less than the settlement preparation period. According to the "Administrative Measures for Settlement of Power Grid Projects", the settlement preparation period is 3 months.

[0045] Verification: Check if the settlement time is after the production start time and calculate the interval between the two. If the settlement time is earlier than the production start time, or the interval is less than the settlement preparation period, it is considered a mismatch.

[0046] Correction: If the settlement time is earlier than the production start time, the settlement time will be adjusted to the production start time plus the settlement preparation period; if the interval is less than the settlement preparation period but the settlement time is after the production start time, the reasons for the early or delayed settlement work will be analyzed based on the actual situation of the project. If the delay is due to insufficient preparation of settlement data, the relevant departments will be urged to speed up the data preparation, and the settlement preparation period will be appropriately extended; if the early settlement is due to the optimization of the settlement process, the adjusted settlement time can be maintained on the premise of ensuring the quality of settlement, but the relevant information must be recorded for future reference.

[0047] (iv) Verification and correction of the mismatch between project settlement time and project final account time: The third construction period rule: the final settlement time should be after the settlement time, and the interval should not be less than the final settlement preparation period. According to the "Specification for the Preparation of Final Settlement of Power Grid Engineering", the final settlement preparation period is 2 months.

[0048] Verification: Check whether the final settlement date is after the settlement date and calculate the interval between the two. If the final settlement date is earlier than the settlement date, or the interval is shorter than the final settlement preparation period, it is considered a mismatch.

[0049] Correction: If the final settlement date is earlier than the settlement date, the final settlement date will be adjusted to the settlement date plus the final settlement preparation period; if the interval is less than the final settlement preparation period but the final settlement date is after the settlement date, analyze the reasons for the early or delayed final settlement work. If the delay is due to incomplete final settlement data, require relevant departments to supplement the data in a timely manner and appropriately extend the final settlement preparation period; if the early delay is due to improved efficiency of the final settlement work, the adjusted final settlement date can be accepted, provided that the quality of the final settlement is guaranteed, and a record should be kept.

[0050] Verification of construction scale information includes: generating alarm information when the project commencement scale does not match the project scale information and individual project scale information in the preliminary design approval document; generating alarm information when the project commencement scale does not match the project scale information and individual project scale information in the project commencement report; and generating alarm information when the project commissioning scale does not match the commissioning scale in the project completion report.

[0051] A scale benchmark database is established. The scale error of the preliminary design is determined based on the approval documents, the construction error of individual projects is determined based on the commencement report, and the scale error at the time of completion is determined based on the acceptance report. In this embodiment, the scale error of the preliminary design is ±5%, the construction error of individual projects is ±3%, and the scale error at the time of completion is ±1%.

[0052] Individual unit size total verification: ∑individual unit size ∈ [total size × 0.95, total size × 1.05]; Material matching verification: cable length ≥ design value × 1.1 (including loss).

[0053] When the discrepancy between the initial design and the actual construction exceeds 5%, payments are frozen and the design change process is initiated. When the production scale is less than 95% of the design value, an incomplete works list is generated. When the completed scale is less than the design value, change orders are compared; if no valid changes are found, the completion report is revised according to the design value, and a "Scale Discrepancy Responsibility Determination Certificate" is generated. For example, the preliminary design approval states that the main transformer capacity is 2×1000MVA, while the completion report states that it is 2×980MVA. A deviation of 1.2% (<5% threshold) was detected, which matched the design change order (DC-2025-012) and marked it as a compliance difference.

[0054] Step S102: Determine the completion time percentage of each sub-project based on the current construction time and the preset construction time; Completion time percentage = Current construction time / Total planned construction time × Preset time percentage, where the total planned construction time is the planned duration of the sub-project, such as 60 days for civil construction, and the current construction time is the actual duration of the sub-project, such as 30 days of civil construction.

[0055] For example, the civil construction time of a certain substation project is 40% of the total planned construction period, which is 60 days. Currently, 30 days of construction have been completed, so the completion time percentage is 60 / 30 × 40% = 20%.

[0056] Step S103: Calculate the construction progress value of each milestone node based on the completion time ratio of the sub-project and the corresponding preset time ratio; The construction progress value of the milestone node is: Where n is the number of sub-projects included in the milestone node.

[0057] For example, the "civil construction" milestone of a substation project includes civil construction of the main control building, civil construction of the relay protection room, cable trench construction, and perimeter wall and gate. Among them, the preset time for civil construction of the control building accounts for 20%, and the completion time accounts for 30%; the preset time for civil construction of the relay protection room accounts for 15%, and the completion time accounts for 50%; the preset time for cable trench construction accounts for 25%, and the completion time accounts for 20%; and the preset time for perimeter wall and gate accounts for 40%, and the completion time accounts for 10%.

[0058] The progress value for "civil construction completed" is: 30%×20%+50%×15%+20%×25%+10%×40%=6%+7.5%+5%+4%=22.5%.

[0059] Step S104: Calculate the construction progress value of each individual project based on the completion time percentage of the milestone nodes and the corresponding preset time percentage; The formula for calculating the construction progress value of a single project is: ,in, To represent the proportion of the total workload completed by the i-th milestone node, =Actual completed workload / Total planned workload × 100% The preset time percentage for the i-th milestone node, where n is the number of milestone nodes in a single project: The logical relationship coefficient is that if node j depends on node i, then the progress value of node j does not exceed the progress value of node i. For example, if the civil engineering is not 80% complete, the equipment installation progress is at most 80%.

[0060] For example, milestones include completion of civil construction, completion of equipment installation, and commissioning. The pre-set timeframe for completion of civil construction accounts for a certain percentage of the total time. It accounts for 30% of the total time spent on the project. The percentage is 80%, with no logical relationship; the percentage of the preset time for equipment installation completion. It accounts for 40% of the total time spent on the project. The percentage is 50%, with the logical relationship being that it depends on the completion of civil construction; the preset time for commissioning and operation accounts for [percentage missing]. For, the percentage of completion time The logical relationship is that the installation of the dependent device is completed.

[0061] Construction completed: P1 = 80% × 30% × 1 = 24%; Equipment installation completed, theoretical value: 50% × 40% = 20%, dependent on civil construction (progress 80%), actual value: min(50%, 80%) × 40% = 20%, P2 = 20% × 1 = 20% (logic relationship coefficient = 1); Commissioning and operation: theoretical value: 20% × 30% = 6%, dependent on equipment installation (progress 50%), actual value: min(20%, 50%) × 30% = 6%, P3 = 6% × 1 = 6%.

[0062] Overall progress of individual project:

[0063] Overall progress value ,in, The construction progress value for a single project is calculated in step S104, representing the actual progress (range 0% to 100%) of the j-th single project. denoted as the percentage of the total budget for a single project, based on the project budget, representing the proportion of the investment amount of the j-th single project to the total project budget (e.g., 20% for a substation and 30% for a transmission line), where m is the number of single projects included in the project.

[0064] For example, a single project includes substation A, cable project B, and overhead line project C. The construction progress of substation A... It accounts for 50%, and the estimated percentage is 50%. The construction progress of cable project B is 20%. It accounts for 30%, the estimated percentage. The construction progress of overhead line project C is 30%. It is 10%, the estimated percentage. If it is 50%, Y = 50% × 20% + 30% × 30% + 10% × 50% = 10% + 9% + 5% = 24%.

[0065] Step S106: Calculate the current theoretical completion value based on the overall progress value and the estimated total investment; The current theoretical completion value is calculated as follows: Overall progress value × Estimated total investment. For example, if the overall project progress value is 24% and the estimated total investment is 200 million yuan, the current theoretical completion value is 24% × 200 million yuan = 48 million yuan.

[0066] Step S107: Calculate the deviation value based on the current theoretical completion value and the actual investment completion value; Wherein, the deviation value = the current theoretical completion value - the actual investment completion value.

[0067] Step S108: Compare the deviation value with the preset value corresponding to the current construction time to obtain the comparison result, and determine the prompt information based on the comparison result.

[0068] In this embodiment, when the deviation value is not less than the preset value, it indicates that the accounting progress is lagging behind, and the prompt message is "Accounting should be expedited"; when the deviation value is less than the preset value, it indicates that the accounting progress is lagging behind, or that the accounting progress is ahead of schedule, and the prompt message is "There may be a situation where the construction site falsely reports completion".

[0069] The determination of preset values ​​includes: acquiring multiple historical infrastructure projects of the same type as power grid infrastructure projects; extracting information to be used that matches the current construction time from the historical construction information of the historical infrastructure projects, including historical deviation values; and determining preset values ​​based on Monte Carlo simulation and the information to be used.

[0070] In this embodiment, at least 30 historical project data of the same type are screened from the project database, and the progress deviation records of each project construction process are extracted, including deviation values ​​during normal construction days, deviation values ​​during extreme weather, and deviation values ​​during equipment failure. The Monte Carlo method is used to conduct 10,000 random samplings to generate a probability distribution curve of deviation values, and to determine dual threshold standards: warning threshold (90% confidence interval): covering 90% of normal deviations; action threshold (99% confidence interval): covering 99% of extreme deviations.

[0071] Before comparing the deviation value with the preset value corresponding to the current construction time, the process includes: determining the construction time period corresponding to the current construction time and the start construction time; obtaining weather information and comparison results for the construction time period; obtaining a first calculated value corresponding to the weather information and a second calculated value corresponding to the comparison results; determining an adjustment coefficient based on the first and second calculated values; adjusting the preset value based on the adjustment coefficient; and comparing the deviation value with the adjusted preset value.

[0072] The calculation of the first calculated value corresponding to the weather information and the second calculated value corresponding to the comparison result include: based on Calculate the first calculated value; based on Calculate the second calculated value; where, For the first calculated value, This is the second calculated value. This refers to the actual number of hours the disaster lasted. Based on the base duration, As a correction factor, This is the deviation value. This is the current preset value.

[0073] The adjustment coefficient is determined based on the first calculated value and the second calculated value, including: based on Calculate the adjustment coefficient; where β is the adjustment coefficient, γ is the risk sensitivity factor, and a is the directional weight index.

[0074] In this embodiment, current construction progress data is collected through IoT devices, and the real-time progress deviation value ΔV is calculated: ΔV = (actual completed value - planned completed value) / planned completed value × 100%; weather warning information issued by the meteorological department is obtained: disaster type: typhoon / rainstorm / dust storm; warning level: red / yellow / blue, expected duration, C1 = λ × (T_d / T_0) × s_w, λ: engineering type coefficient, of which electrical engineering 1.3, civil engineering 1.0, T_d: number of hours of disaster duration, T_0: base duration, of which red warning 24h, yellow warning 48h; s_w: disaster intensity coefficient, of which typhoon 1.5, rainstorm 1.2; deviation state factor calculation: when ΔV>V_s: C2 = |ΔV| / V_s; when |ΔV|≤V_s: C2 = 1; when ΔV<-V_s, C2 = V_s / |ΔV|; γ: risk sensitivity coefficient 0.6-0.9, α: directional weight, where lead is 1.2 and lag is 0.8.
