[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 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 power 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 to enable the user to perform 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 instructions for the distribution network planning project, such as the business personnel's estimated project planning start and commissioning time. For demand-based new 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. For existing transformation projects, users can enter information on existing power grid equipment and facilities.

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

[0120] In the present embodiment, the planning operation can be performed according to the key information carried in the power distribution network planning project generation instruction and the preset time sequence section data and typical design tool library, so as to generate operation result data. For example, the key information such as project name, geographical location, voltage level, etc. Specifically, according to the time sequence section data and the typical design tool library, a canvas operation tool can be provided, including operation options such as new construction, expansion, reconstruction, and demolition of devices and facilities such as substations, lines, distribution station buildings, and power pipe trenches. The user can select the type of device and facility to be planned and the type of operation, for example, to newly construct a substation or to reconstruct a section of line. According to the user's selection, the system can automatically obtain the corresponding design scheme from the typical design tool library and generate the corresponding station diagram and device list. The generated station diagram and device 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: When the operation result data is checked and verified, the preset comprehensive cost tool library is used to perform calculation on the operation result data to obtain planning project investment data.

[0122] In the present embodiment, the server first checks the operation result data for duplication, queries the repeated construction projects for reconstruction and demolition of the same existing equipment in the past three years. This process can be performed through database query and comparison to ensure project logic and reduce investment waste. The server then queries the existing status power grid problem list according to the existing equipment involved in the operation result data and automatically associates it with the project to strengthen the necessity of the project and achieve one item with multiple functions. This process can be performed through data matching and association to ensure the rationality and effectiveness of the project. After the project duplication and problem verification, the server performs investment calculation. Based on the operation result data, combined with the preset comprehensive cost tool library, the comprehensive cost data such as equipment purchase cost, construction engineering cost, installation engineering cost, and other costs required by the project are automatically calculated. This process can be performed through data calculation and analysis to obtain the investment data of the planning project.

[0123] The entire data processing process is automatically performed on the server, and the operation result data is checked, verified, and investment calculated through the preset tool library and algorithm, so as to obtain the investment data of the planning project. This can improve the efficiency and accuracy of data processing and provide reliable data support for the decision-making of the planning project.

[0124] Step S304: Based at least on the operation result data and the planning project investment data, a power distribution network planning operation result is generated.

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

[0126] In some embodiments, in step S302, the planning operation can be performed based on the diagnostic analysis result data, the power distribution network planning project generation instruction, and the preset time sequence section data and typical design tool library, to generate operation result data. The planning operation can also be performed based on the load prediction result data, the power distribution network planning project generation instruction, and the preset time sequence section data and typical design tool library, to generate operation result data.

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

[0128] In summary, in the above-mentioned embodiments, by receiving the user input planning project generation instruction, automatically performing the planning operation and generating the operation result data, the automation of the power 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, and the existence of repeated construction projects and the status of the power grid is avoided, and the quality of the planning project is improved. Using the preset comprehensive cost tool library to calculate the operation result data, the investment data of the planning project is obtained, which helps the planning personnel to better evaluate the investment demand of the project and optimize the efficiency of the use of funds. Based on the operation result data and the planning project investment data, the power distribution network planning operation result is generated, including the planning scheme, the investment plan and the project report, etc., to provide comprehensive information support for decision makers.

[0129] In some embodiments, the time-series section data is obtained by a method comprising: performing data freezing on section data based on a time-series section cutting task created by a first account; wherein the section data at least includes power grid graphic data, device facility account data, or topology connection data;

[0130] performing cutting and labeling operations on the section data based on a second account to obtain the frozen section data; wherein the first account has higher authority than the second account;

[0131] performing topology analysis and network frame analysis based on the topology connection data to obtain data quality evaluation indexes;
