This can improve the efficiency of planning operations, reduce manual intervention, and reduce the time cost of planning operations. After the operation result data is checked for duplicates and verified, the data is calculated using the preset comprehensive cost tool library to obtain the investment data of the planning project. This can ensure the consistency and accuracy of the operation result data and avoid unreasonable planning schemes caused by data errors. The operation result data is calculated by using the preset comprehensive cost tool library to obtain the investment data of the planning project.

The present application combines the characteristics of automated execution, data consistency and accuracy, and comprehensive cost calculation, which can improve the efficiency and accuracy of planning operations, provide a scientific and reasonable planning scheme for distribution network planning, and help optimize the power grid structure and improve the power grid operation efficiency.

[0089] More specifically, in the project online compilation module, the following operations are mainly included:

[0090] Based on the diagnosis conclusions of the power grid, access demand and load forecast, a planning target grid plan is proposed. Based on the project granularity and the results of steps 1-7, online planning operations are carried out, including project creation, planning operations, project duplication checking, problem verification, investment estimate, milestone planning, project confirmation and other processes. The project construction scale and investment estimate are automatically summarized to form a planning project list.

[0091] Step 101: Project creation, create a planned project, and automatically generate a project name based on the key elements of project naming, including the first, second, and third-level functional classifications of the project, the project location, the voltage level, the name of the equipment and facilities, etc. The business personnel estimate the planned start and commissioning time of the project; demand-type new projects such as land development supporting new construction projects, power supply access supporting projects, user access supporting projects related to land development projects, power supply access applications, business expansion and installation work orders and other information; existing transformation projects are related to the existing power grid equipment and facilities involved in the diagnosis of problems, to ensure that the necessity of project establishment is sufficient.

Based on the selected typical design, a station diagram and a station equipment list are generated with one click, and an association relationship is automatically established with the planning project.

[0093] Step 103: Check for duplicate projects. Use the results of step 103 as a benchmark to search for duplicate construction projects that have been carried out to renovate or demolish the same existing equipment in the past three years to ensure project logic and reduce investment waste.

[0094] Step 104: Problem verification. As the work content in step 103 involves existing equipment, a list of existing power grid problems is queried and automatically associated with the project, thereby reinforcing the necessity of the project and achieving multi-functionality.

[0095] Step 105: Investment estimate. Based on the result of step 103 and the comprehensive cost of step 6, the investment estimate of the planned project is generated with one click. The business personnel adjust the project investment ratio according to the source of project funds.

[0102] Step 114: Verify planning objectives, calculate changes in indicators such as power supply quality, power supply capacity, grid structure, intelligent development, equipment level, new energy and distributed power consumption in the planning area before and after the project is put into the database, and evaluate and analyze the planning results.

[0103] Step 115: Planning report atlas, combined with the results of steps 1-10, combined with the planning report template, extract the corresponding indicator data, generate a planning report, and generate a year-by-year planning grid geographic wiring diagram atlas based on the results of the above drawing in step 10.

[0104] Step 116: The projects are reviewed and put into storage. The list of planning projects that have passed the review and inspection is reported to the higher authorities step by step and released for storage.

[0105] More specifically, in the project adjustment and call-out module, the following operations are mainly included:

[0106] Step 121: Adjust related issues / demands. Adjust the planned project support access needs or pre-solve existing power grid problems without withdrawing the project from the database.

[0107] Step 122: Adjust the construction management unit. According to the clarification of the project construction management unit, adjust the project construction management unit and regenerate the WBS code to support the issuance of the project investment plan and the start of construction.

[0108] Step 123: Adjust the planning schedule. Adjust the planned project start time and regenerate the planning milestone plan without withdrawing the project from the warehouse.

[0109] Step 124: Adjust the planning scheme, adjust the planning project construction plan, compare the changes before and after the adjustment, and initiate an adjustment application. After review and approval, replace the original project plan.

[0110] Step 125: Plan the project out of the library, call out the abandoned planned projects from the project library, identify and analyze other projects that have power-related projects with the project plans to be called out, call out or adjust the project plans together, and ensure the feasibility of the projects in the library.

[0111] To sum up, this scenario example, on the one hand, uses the big data operation platform to realize the online operation of the entire distribution network planning process, effectively improving the efficiency of distribution network planning operations. On the other hand, it not only overcomes the problems of traditional power grid planning, such as separation of diagrams and numbers, unclear diagnosis, unclear problems, single planning operation tools, and shelving of planning results, but also improves the efficiency of planning operations and has great promotion and application value.

[0112] Example method:

[0113] Example 1

[0114] like Figure 3 As shown, this embodiment provides a method for generating distribution network planning operation results, which can be applied to a server, and the method may include:

[0115] Step S301: receiving a distribution network planning project generation instruction input by a user.

[0116] In this embodiment, the receiving action may be represented as the server receiving a distribution network planning project generation instruction from the client.

[0117] In this embodiment, the distribution network planning project generation instruction may be that the user performs one or more desktop operations through the client, so that the client generates the distribution network planning project generation instruction, and the instruction is transmitted to the server through the network.

[0118] It is understandable that a corresponding interactive interface can be configured in the client so that the user can make one or more desktop operations. For example, the client sets the corresponding UI elements in the client so that the user can create a planning project, name the key elements according to the project, and provide an input box so that the user can enter the necessary information for generating distribution network planning project generation instructions, such as business personnel estimating the project planning start and commissioning time. For new demand-based projects, users can enter information such as new land development supporting projects, power supply access supporting projects, user access supporting projects related to land development projects, power supply access applications, business expansion and installation work orders, etc. For existing transformation projects, users can enter information on existing power grid equipment and facilities.

[0119] Step S302: Execute planning operations based at least on the distribution network planning project generation instructions and preset time-series section data and typical design tool library, thereby generating operation result data.

[0120] In this embodiment, the planning operation can be performed according to the key information carried in the distribution network planning project generation instruction and the preset time-series section data and typical design tool library, so as to generate the operation result data. For example, key information such as project name, geographical location, voltage level, etc. Specifically, according to the time-series section data and the typical design tool library, a canvas operation tool can be provided, including operation options such as the construction, expansion, transformation, and demolition of equipment and facilities such as substations, lines, distribution stations, and power pipe trenches. The user can select the type of equipment and facilities and the type of operation to be planned, such as building a new substation or transforming a section of line. According to the user's choice, the system can automatically obtain the corresponding design scheme from the typical design tool library and generate the corresponding station diagram and equipment list. The generated station diagram and equipment list are automatically associated with the planning project to ensure that the operation result data corresponds to the planning project one by one. The user can view, modify and optimize the generated operation result data to ensure the accuracy and completeness of the planning scheme.

[0121] Step S303: After the operation result data has been checked for duplication and verified, a preset comprehensive cost tool library is used to perform calculations on the operation result data to obtain planned project investment data.

[0122] In this embodiment, the server will first check the duplicate operation result data and query the duplicate construction projects that have been transformed and demolished for the same existing equipment in the past three years. This process can be carried out by database query and comparison to ensure project logic and reduce investment waste. The server will then query the existing list of power grid problems based on the existing equipment involved in the operation result data and automatically associate it with the project to strengthen the necessity of the project and achieve multiple functions. This process can be carried out by data matching and association to ensure the rationality and effectiveness of the project. After passing the project duplication check and problem verification, the server will perform an investment estimate. Based on the operation result data, combined with the preset comprehensive cost tool library, the comprehensive cost data such as equipment purchase costs, construction engineering costs, installation engineering costs, and other costs required for the project are automatically calculated. This process can be carried out by data calculation and analysis to obtain the investment data of the planned project.

[0123] The entire data processing process is automated on the server side. Through the preset tool library and algorithm, the operation result data is checked for duplicates, verified, and the investment is estimated, thereby obtaining the investment data of the planning project. This can improve the efficiency and accuracy of data processing and provide reliable data support for decision-making of planning projects.

[0124] Step S304: Generate distribution network planning operation results based at least on the operation result data and the planned project investment data.

[0125] In this embodiment, the operation result data after duplication checking, verification and investment estimation and the investment data of the planning project are integrated to ensure the integrity and accuracy of the data. Based on the integrated data, the system can automatically generate a distribution network planning scheme. This includes specific plans for various projects such as new construction, renovation, and demolition, including the layout and design of equipment and facilities such as substations, lines, distribution stations, and power trenches. Based on the planning scheme and investment data, the system can generate an investment plan for the distribution network planning project. This includes the budget, funding sources, investment allocation, etc. of each project to ensure that the funding needs and use of the project are in line with the actual situation. The system can generate a detailed report on the distribution network planning project based on the planning scheme and investment plan. The report content includes a description of the planning scheme, an analysis of the investment plan, suggestions for project implementation, etc., to provide comprehensive information support for decision makers. Finally, the system can output and display the generated distribution network planning operation results in the form of reports, charts, maps, etc., which are convenient for users to view and share. At the same time, the data can also be exported to other systems or software for further analysis and application.

[0126] In some embodiments, in step S302, a planning operation may be performed based on the diagnostic analysis result data, the distribution network planning project generation instruction, preset time series section data, and a typical design tool library, thereby generating operation result data. Alternatively, a planning operation may be performed based on the load forecast result data, the distribution network planning project generation instruction, preset time series section data, and a typical design tool library, thereby generating operation result data.

[0127] In some implementations, in step S304, the distribution network planning operation result may also be generated based on the geographic information data, the power load data or the equipment technical parameter data, the operation result data and the planned project investment data.

[0128] In summary, in the above-mentioned implementation mode, by receiving the planning project generation instruction input by the user, automatically executing the planning operation and generating the operation result data, the automation of the distribution network planning process is realized, and the work efficiency is improved. By checking and verifying the operation result data, the accuracy and consistency of the data are ensured, the existence of duplicate construction projects and current power grid problems is avoided, and the quality of the planning project is improved.
