[0002] With the continuous expansion of the power grid scale and the deepening of the construction of the new power system, the grid framework structure and operation mode show a high degree of complexity. In this context, in a comprehensive software application system integrating power grid topology analysis, maintenance plan data flow, and multi-business scenarios, the information interaction and logical wiring relationship complexity between maintenance equipment have increased significantly. The traditional way of relying on text descriptions or table displays of field information to convey the maintenance plan information of system equipment can no longer effectively display the topological structure, equipment layout, and line connection mode of the power system, that is, the mutual relationship between key facilities such as power plants, substations, power transmission and transformation lines, and power generation equipment.

[0003] The list-style information display method restricts the improvement of power system management efficiency, the optimization of operation performance, and the shortening of fault recovery time. To ensure the safe and stable operation of the system and provide a more intuitive, convenient, and efficient working platform for system management personnel, constructing a high-efficiency graph-model integrated page data XML generation system that can clearly display the association and topological structure between each device can effectively improve the rationality, scientificity, and effectiveness of the decision-making of operation planners. This system aims to intuitively display the complex structure of the power system through graphical means and promote the intelligence and refinement of system management.

[0004] According to the complexity of the power system and the increasing construction requirements, the present invention innovatively proposes a method for designing a graph-model integrated system structure based on mxGraph and G6. This method aims to closely combine the core services such as the equipment maintenance plan, maintenance risk assessment, and grid connection form of the power system with graphical display, so as to construct an intuitive and efficient power grid framework structure.

[0036] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Example 1, referring to Figure 1 , which is an embodiment of the present invention, provides a method for generating power system XML based on mxGraph and G6, including:

[0038] S1: Collect the first object parameter data and analyze the parameter data to obtain the influencing parameters.

[0039] Collect the power system parameter data and analyze the conditions that the parameter data needs to meet when implementing the function.

[0040] In this embodiment, the first object includes the power system, and the influencing parameters include the parameters that affect the construction of the power system influence diagram model and the function. The process of analyzing the parameter data to obtain the influencing parameters is specifically

[0041] It should be noted that by collecting data through the first object parameter, the first data required for generating the integrated diagram model is obtained. Such as voltage, current, power, frequency, impedance, phase angle, etc., as well as the status information of the equipment (such as online / offline, faulty / normal) and the network topology structure information.

[0042] Preferably, before generating the integrated diagram model parameter data, it also includes two steps of data preprocessing and data algorithm model analysis. Specifically,

[0043] The first step, data preprocessing: Clean, verify and format the collected raw data to ensure the accuracy and consistency of the data.

[0044] The second step, data algorithm model analysis:

[0045] First, feature extraction: Use statistical methods to extract the key features in the parameter data, and these features can reflect the operating status and functional requirements of the power system.

[0046] Further, formula processing:

[0047] Correlation analysis: Use the Pearson correlation coefficient formula to evaluate the linear or non-linear correlation between parameters. The Pearson correlation coefficient formula is:

[0048]

[0049] where x i , y i are the i-th observations of two parameters; x̄, ȳ are the means, and n is the number of observations.

[0050] Based on the analysis results of the data algorithm model, identify the parameters that have a direct or significant impact on the construction of the power system diagram model data and the realization of functions. These influencing parameters may include key equipment parameters, network topology parameters, and operating status parameters of the power system, etc.

[0051] Sort out and output the influencing parameters obtained from the analysis and their related information (such as parameter names, data types, influencing degrees, conditions met, etc.) to provide basic data support for subsequent steps (such as diagram model construction, XML generation, etc.).

[0052] By introducing formula processing, we can analyze the power system parameter data more precisely and quantitatively, so as to accurately identify the key parameters that affect the construction of the power system diagram model and the realization of functions. This method not only improves the accuracy and efficiency of the analysis, but also provides strong technical support for the optimal design and operation management of the power system.

[0053] S2: Perform conversion processing on the influencing parameters to obtain diagram model data.

[0054] Sort out and convert the parameter data according to the required conditions, and construct a front-end drawing library to obtain diagram model data.

[0055] In this embodiment,

[0056] Mainly perform conversion processing on the influencing parameters identified in step S1 to construct the diagram model data required by the front-end drawing library. In this process, we will clean, verify, and format the format of the parameter data to ensure the accuracy and consistency of the data. At the same time, for the situation of missing data, we will use the interpolation method to fill it.

[0057] First, clean and verify the data format, including removing invalid data, format verification, data cleaning, etc.

[0058] Remove invalid data: Delete invalid or redundant information in the parameter data, such as null values, duplicate values, or data that does not meet the format requirements.

[0059] Format verification: Check whether the format of parameter data meets the requirements of the front-end drawing library, such as data type, data range, data accuracy, etc. For data that does not meet the requirements, format conversion or correction is required.

[0060] Data cleaning: Processing outliers or noise in parameter data, such as improving data accuracy through smoothing, denoising, etc.

[0061] Further, data interpolation is performed:

[0062] For the missing parts of parameter data, we use interpolation to fill them in. Interpolation is a method of inferring unknown data points based on known data points, and is often used to fill in missing data.

[0063] The specific interpolation method can be selected according to the characteristics and requirements of the data. In this embodiment, we use linear interpolation to fill in.

[0064] The linear interpolation formula is:

[0065]

[0066] By using this formula, we can calculate the dependent variable value y for the missing data point 插值 .

[0067] Therefore, the data is formatted, and the parameter data after cleaning, verification and filling is first converted into a format suitable for the front-end drawing library, including data type conversion, data structure adjustment, etc.

[0068] Furthermore, the front-end drawing library model data is constructed, and the formatted parameter data is imported into the drawing library according to the API and data format requirements of the front-end drawing library.

[0069] Use the functions and methods provided by the drawing library to build the power system model data based on the parameter data. Create elements such as nodes (representing generators, transformers, etc.), edges (representing transmission lines), labels (displaying information such as device names and parameter values), and set their properties (such as position, size, color, etc.).

[0070] Through the above steps, the influencing parameters can be converted into graphic model data suitable for use by the front-end drawing library, and the accuracy and consistency of the data can be ensured. At the same time, the interpolation method is used to fill in the missing parts of the data, which improves the integrity and availability of the data.

[0071] S3: Establish a format conversion model to parse and adjust the image data to obtain XML format data.

[0072] The graph model data is parsed into the structure required for subsequent processing through a format conversion model, and the graphics are configured according to the adjusted graph model data, and the configured graphics are adjusted and tested.

[0073] Both mxGraph and G6 are front-end drawing libraries, but there are essential differences in their data models, rendering mechanisms, and interaction logics, resulting in the following technical obstacles in direct combination:

[0074] 1. Incompatible data models

[0075] mxGraph: A tree structure model based on cells (Cell), where each node / edge contains geometric attributes (position, size), styles (color, shape), and business metadata.

[0076] G6: A flattened structure based on a graph data model, where nodes / edges are defined in the form of JSON arrays, associated by id, and have no hierarchical nesting.

[0077] 2. Differences in rendering mechanisms

[0078] mxGraph: Depends on SVG / VML rendering, emphasizing topological editing capabilities (dragging, connecting lines, grouping).

[0079] G6: Based on Canvas / WebGL rendering, focusing on the visualization of dynamic relationship networks (layout algorithms, animation effects).

[0080] 3. The format gap between XML and JSON

[0081] mxGraph exports XML: Contains complex nested levels and redundant metadata (such as <mxgeometry> 、 <mxcell>)。

[0082] The required data format for G6: flattened JSON structure (such as {nodes:[...],edges:[...]}).

[0083] In order to overcome the obstacles in the combination of mxGraph and G6 technologies, a format conversion model is designed:

[0084] By constructing an intermediate layer conversion engine, the data and interaction gap between the two libraries is solved. The model architecture is as Figure 2 ,。

[0085] The core modules of the intermediate layer conversion engine are shown in Table 1:

[0086] Table 1 Core Module Table

[0087]

[0088] Furthermore, a format conversion model is designed, and the key technical implementation steps are:

[0089] 1. Parse mxGraph XML and extract structured data as shown in the figure.

[0090] 2. Define a two-way mapping rule library as Figure 4 。

[0091] 3. Process differential compensation (hierarchical structure) as Figure 5 。

[0092] 4. Generate G6 standard JSON as Figure 6 。

[0093] 5. Reverse conversion (G6 → mxGraph XML) as Figure 7 。

[0094] After being processed by the format conversion model, the key technical obstacles solved are shown in Table 2:

[0095] Table 2 Obstacle Technology Table

[0096]

[0097] Through this model, while retaining the powerful editing ability of mxGraph, the high-performance rendering and dynamic interaction characteristics of G6 are utilized to achieve a graph-model integration solution for the power system.

[0098] Example 2, an embodiment of the present invention, provides a method for generating power system XML based on mxGraph and G6.

Plan the page layout, including the canvas position, node and connection layout, filtering panel layout, toolbox operation layout, etc.

[0100] Create a canvas container and use graphical modeling technology to construct a canvas that meets the function of drawing graphics. Add Add node element element, and use the API of mxGraph to add the node element to the drawing area. Add connection Elements to represent the associations or connections between nodes. Support custom nodes and connections, draw different electrical components using SVG elements according to business requirements, and import them into the drawing board as node materials for diagram model editing.

[0101] Set the style attributes of the nodes and connections, including colors, shapes, fonts, etc., to meet the page design requirements.

[0102] Analyze the interactive functions of the business requirements and configure and implement them one by one. Listen to various events of mxGraph to implement specific functions, such as updating the connection position, triggering specific operations, etc. Save the edited diagram model data in XML format.

[0103] Deconstruct the XML data and convert it into a JSON format recognizable by G6. Use G6 technology to create and configure the graphics, define the data and styles, and implement interactive operations.

[0104] Finally, perform debugging and testing to ensure that the graphical display and interactive functions are normal.

[0105] Embodiment 3, an embodiment of the present invention, provides a power system XML generation system based on mxGraph and G6, including an acquisition and analysis module, a parsing and processing module, and a configuration and adjustment module.
