[0053] Reference Figure 1 and Figure 2 This is a system graphical interaction method between power grid systems provided in one embodiment of the present application, comprising:

[0054] S1: Export the domain data and graphic data from the system graphics of the source system to generate CIM model files and SVG graphic files respectively;

[0055] S2: Determine the mapping relationship between the CIM model file and the SVG graphic file;

[0069] As described in step S1 above, the domain data and graphic data in the system diagram of the source system are exported to generate CIM model files and SVG graphic files, respectively. The domain data includes the CIM model (i.e., the metadata model) of the system diagram, as well as the exchange types of the required devices, metadata elements, and corresponding metadata attributes within the model, as detailed in the table below:

[0070]

[0071]

[0072] The SVG graphics file contains definitions of system graphics chart objects, graphic objects, group objects, chart views, layer definitions, metadata objects, etc., as detailed in the table below:

[0073]

[0074] Figure 2 The SVG viewer in the document is not required; it is only used as a way to verify the correctness of the SVG document. It can be used to locate problems during the export and import process. The import program of the target system is responsible for reporting and handling inconsistencies between the graphics and the model, such as whether domain data is missing.

[0075] As described in step S2 above, determining the mapping relationship between the CIM model file and the SVG graphic file involves determining which type of normative reference and implementation the CIM model and the SVG graphic are based on.

[0076] As described in steps S3-S4 above, domain data import should precede graphic data import; otherwise, the references from graphics to domain objects cannot be resolved. That is, when importing into the target system, the CIM model file must be imported first, followed by the SVG graphic files. Otherwise, the references from graphics to domain objects cannot be resolved. After importing the CIM model file and SVG graphic files into the target system, the target system will create an interactive graphic file suitable for the target system based on its required device information and corresponding mapping relationships, and will perform normalization processing on the new SVG graphic file, such as setting colors, scaling, logos, width, height, background color, and foreground color to conform to the target system.

[0077] In one embodiment, the step of determining the mapping relationship between the CIM model file and the SVG graphic file includes:

[0078] The CIM model file and the SVG graphic file are parsed respectively to obtain the equipment information in the CIM model file and the graphic element information in the SVG graphic file;

[0079] The mapping relationship between the CIM model file and the SVG graphic file is generated based on the reference between the device information and the graphic element information.

[0080] As described above, after obtaining the system graphics of the source system, the system graphics CIM model file and the SVG graphic file are extracted and parsed to obtain the required equipment information in the CIM model file and the primitive information used in the SVG graphic file. Based on the CIM model, the reference relationship between the extracted equipment information and the primitive information is determined. According to the reference relationship between the two, the mapping relationship between the CIM model file and the SVG graphic file can be determined, that is, the above-mentioned normative reference relationship, to map the connection relationship between the CIM model and the graphics.

[0081] In one embodiment, the step of sequentially importing the CIM model file and the SVG graphic file into the target system to generate a new CIM model file and a new SVG graphic file, and then completing the mapping between the new CIM model file and the new SVG graphic file in the target system based on the mapping relationship includes:

[0082] The SVG graphic file is loaded into the import program of the target system and traversed to obtain the layer information of the SVG graphic file.

[0083] The CIM model file is loaded into the import program of the target system for parsing to obtain the CIM model;

[0084] Obtain the device object information of the target system;

[0085] Associate the CIM model with the device object information of the target system to generate a new CIM model file;

[0086] The layer information is imported into the new drawing, and the device object information in the new CIM model file and the layer information are mapped between the new CIM model file and the new SVG graphic file in the target system.

[0087] As described above, based on the import program in the target system, the SVG graphic file is traversed to obtain the layer information of the SVG graphic file. This layer information includes: a static background layer (Head_Layer), a power equipment component layer, a static text layer (Text_Layer), a measurement layer (MeasurementValue_Layer), a connection layer (Link_Layer), other layers (Other_Layer), and a hotspot layer (Ref_Layer). The static background layer includes the width, height, background color, and foreground color of the entire graphic. The power equipment component layer is layered according to different power equipment component types, including both AC and DC components: such as the Bus_Layer, Load_Layer, AC segment endpoint layer (ACLineSegment_Layer), AC segment layer (ACLine_Layer), Circuit breaker layer (Breaker_Layer), Disconnector layer (Disconnector_Layer), and Grounding switch layer (Gro). The following layers are included: undDisconnector_Layer, two-roller transformer layer (Transformer2_Layer), three-roller transformer layer (Transformer3_Layer), generator layer (Generator_Layer), terminal equipment layer (Terminal_Layer), dollyBreaker layer (DollyBreaker_Layer), capacitor layer (Compensator_Layer), reactor layer (Reactor_Layer), voltage transformer layer (PT_Layer), current transformer layer (CT_Layer), DC switching equipment layer (DCSwitch_Layer), DC commutator layer (HLJ_Layer), DC terminal equipment layer (DCTerminal_Layer), DC grounding equipment layer (DCGroundTerminal_Layer), DC conductor layer (DCLine_Layer), and DC conductor end layer (DCLineSegment_Layer); the static text layer is used for static text. <text>Element or primitive descriptions mainly include coordinate position, font size, type, font direction, color, etc.; the measurement layer is used to describe dynamic text information, and compared with static text, it includes more... <metadata / > Information such as ObjectID within the element. For measurements on the device, the format ObjectID = "Device Name: Measurement Type" is used. The advantage of this is that the importing party can directly generate measurements for the device based on the "Device Name" and "Measurement Type" information, eliminating the need for mapping with CIMXML. The connection relationship layer is used to describe the connection lines on the diagram. <path>Elements include descriptive information such as the start and end points of the connecting lines, the coordinates of each inflection point, color, and line width. The following information is optional: The connection relationships of the graphics are described in this layer, including the total number of devices connected by the connecting lines, the specific device ID at each end, and which terminal the connecting line is connected to. Other layers are used to store objects that do not have electrical meaning. The hotspot layer is used to handle all photosensitive points. For example, for hotspots on the graphics, they can be linked to the SVG file using the following method:

[0088] <a xlink:href＝"***.svg">

[0089] For example

[0090] <a xlink:href＝"广电_220kv某某变.svg">

[0091] <rect x="0"y="0"width="227"height="80"fill-opacity="0"stroke-opacity="0"stroke-width="2" / >

[0092] .

[0093] Where x and y are the coordinates of the hot spots on the graphic, width is the width of the graphic, height is the height of the graphic, fill-opacity represents the fill opacity of the graphic, stroke-opacity represents the border opacity, and stroke-width represents the border width.

[0094] The CIM model file will then be loaded into the import program of the target system for parsing to obtain the CIM model. Based on the parsed CIM model, device object information adapted to the target system, such as device name and ID, will be obtained. Then, the mapping between the new CIM model file and the new SVG graphic file will be completed through the mapping relationship between the CIM model file and the SVG graphic file obtained above.

[0095] In one embodiment, the step of performing normalization processing on the new SVG graphic file includes:

[0096] Examine the header of the new SVG graphic file, which contains version information for the XML application;

[0097] Specifically, there are several parameters to pay attention to during the header file verification process:

[0098] XML version: This refers to the XML version used. Since SVG graphics are based on XML, an SVG document must also contain XML declarations and a root element. The currently used version is 1.0.

[0099] Character encoding uses UTF-8

[0100] The DOCTYPE should specify whether it is SVG or the SVG version.

[0101] The root element of an SVG primarily describes the width and height of the entire graphic, as well as its namespace. `width` and `height` describe the width and height of the canvas, and `viewBox` allows for translation and transformation within the local coordinate system. The main namespaces are: <svg>The element is in the namespace http: / / www.w3.org / 2000 / svg, which is the default namespace. Two other namespaces are required.

[0102] xmlns:xlink="http: / / www.w3.org / 1999 / xlink", xmlns:cge="http: / / iec.ch / TC57 / 2005 / SVG-schema#"; It is worth mentioning that when converting the representation between the source system and the target system, the transmitting side needs to express the representation. Whether the importing side needs to and how to handle these representations can be considered separately. The representation is mainly reflected in the defs, for example:

[0103] <defs> ...

[0105] < / defs> .

[0106] According to the requirements of the primitive objects in the target system, the first primitive object contained in the new SVG graphics file is replaced with the second primitive object required by the target system;

[0107] Specifically, graphic elements describe how different power system objects are displayed in the diagram. For example, a switch can be displayed as a trolley shape or a standard switch shape. The corresponding graphic elements in the source system are replaced with the graphic elements of the target system. Among them, graphic element objects include: substations / electricity rooms, feeder switches, load switches, disconnect switches, circuit breakers, knife switches, grounding knife switches, transformers, busbars, overhead lines / cables, connecting lines, annotation text, base map, and layers.

[0108] Based on the style of the visualization elements required by the target system, the first visualization element contained in the new SVG graphic file is replaced with the second visualization element required by the target system.

[0109] Specifically, in a VG document, shapes, paths, or groups can be copied to multiple different locations within the document, by using... <use>An element references an element defined elsewhere in the document. Generally, the referenced element is placed in a... <defs>The interior of the element, up to a <use>The graphics are drawn only when an element references these elements. <defs>The element is only used to define the referenced element; it does not perform the actual drawing and rendering of the element.

[0110] Graphic primitives are converted into symbol elements in SVG. <symbol>This is used to define an image template. The defined template can only be accessed through... <use>Elements are referenced as instances for actual rendering. For example, a knife switch primitive is converted into two states, open and closed, respectively, in the SVG document. <symbol>element.

[0111] In one embodiment, after the step of replacing the first visual element contained in the new SVG graphic file with the second visual element required by the target system according to the style of the visual element required by the target system, the method further includes:

[0112] Define a reference to the new SVG graphics file in the target system, the definition steps including:

[0113] Set an identifier containing specific elements in the second primitive object;

[0114] When the second primitive object is referenced, the second primitive object is drawn to the reference location using the identifier.

[0115] As described above, in the above steps, primitives are defined, that is, by using... <use>The element references an element defined elsewhere in the document.

[0116] <use>The syntax for elements is:

[0117] <use xlink:href="#some_local_uri" / > .

[0118] In SVG, references can use absolute or relative URLs. The "xlink:href" example above doesn't require the "url" keyword; alternatively, you can use `url(#xpointer(id-name))`. For instance, the actual knife switch object is drawn using... <use>The reference to the element will be the one corresponding to "Disconnector". <symbol>The element is drawn to the reference.

[0119] It is worth mentioning that after defining the coloring style and style name for each voltage level, referencing a selector in a specific element requires using the "class" attribute.

[0120] In one embodiment, after the step of drawing the second primitive object to the reference location using the identifier when the second primitive object is referenced, the method further includes performing coordinate transformation on the second primitive object, the transformation step including:

[0121] Obtain the initial coordinates of the second primitive object in the image template;

[0122] The actual coordinates of the second primitive object in the new SVG graphic file are calculated based on the initial coordinates, using the following formula:

[0123]

[0124] Where x and y are the initial coordinate values ​​of the second primitive object in the image template, and x1 and x2 are the actual coordinate values ​​of the second primitive object in the new SVG graphic file. The coordinate transformation expression when referencing the image template is as follows:

[0125] transform = matrix(abcdef),

[0126] a, b, c, d, e, and f are elements within the matrix in the transform matrix function, and all are constants.

[0127] As mentioned above, the coordinate transformation utilizes matrix operations to transform the original coordinates of the image template symbol position into the actual coordinates on the SVG graphic. The formula for calculating the matrix transformation of a two-dimensional coordinate system is:

[0128]

[0129] Where x and y are the initial coordinate values ​​of the second primitive object in the image template, and x1 and x2 are the actual coordinate values ​​of the second primitive object in the new SVG graphic file. The coordinate transformation expression when referencing the image template is as follows:

[0130] transform = matrix(abcdef),

[0131] Where a, b, c, d, e, and f are elements within the matrix of the transform matrix function, and all are constants.

[0132] In one embodiment, the step of performing normalization processing on the new SVG graphic file further includes:

[0133] Define the topological representation relationship between the second primitive objects in the new SVG graphics file;

[0134] The connection relationships among all devices are determined based on the topological representation relationship.

[0135] As mentioned above, for general SCADA diagrams, it is recommended that all devices be directly associated with the ConnectiveNode in the CIM, as this reduces the need for endpoint representation. For the topologically topologically optimized bus branch model diagram, it is recommended that the CN_Ref be directly the bus. For example:

[0136]

[0137]

[0138] For the receiving end, this description is complete in terms of topology, fully representing the connection relationships between all devices. This allows the receiving end to perform topology analysis graphically even without CIM files or data. The SVG graphic ID is implemented using a format where 'g' is followed by 'id', i.e.<g id="BS-3"> .
