Finally, based on the integration of symbol templates, graphic connections, model associations and other aspects of logical symbols, the protection logic diagram model is established through composite signal construction and symbol template reference.

[0046] At present, the protection logic diagram of the relay protection industry has no structured data, and each link in the back end can only carry out related applications through the image information carried by the manual. At the same time, due to the lack of correlation with the IPD model and the ICD model, the internal principle of the device still exists as a black box in terms of device testing, on-site digital twins, integrated query of optoelectronic circuits, fault diagnosis, intelligent operation and maintenance, etc., which greatly limits the improvement of the intelligence and digitization of the secondary system of the substation. The present invention abstracts the symbols and attributes required for the protection logic diagram through an object-oriented method, breaking the black box status of the internal protection logic principle of the device for a long time, establishing a structured data model of the device protection logic, filling the gap in the modeling of the internal protection logic of the device, and connecting the IPD model, ICD model and the internal protection principle data of the device, realizing the "last mile" of substation relay protection, that is, the data connection of the internal protection logic of the device, which will provide strong data support for the debugging, fault diagnosis, simulation test, intelligent operation and maintenance of the relay protection equipment principle and other links.

[0053] Research on related technologies has limited focus on testing protection logic. Currently, there is no technology for modeling and correlating relay protection logic diagrams. To address the challenges of standardizing protection logic diagram models and sharing data, and to provide robust data support for debugging, fault diagnosis, and intelligent operation and maintenance of relay protection equipment, a method for modeling and correlating protection logic diagrams is needed.

[0054] The present invention provides a protection logic diagram modeling and multi-model association method, including:

[0055] Acquire each logical symbol of the protection logic diagram and establish a symbol template for each logical symbol;

[0056] Define protection logic diagram model elements; wherein the elements are used to represent protection function logic scenarios, and the logic scenarios include graphics composed of logic symbols and corresponding logical connection relationships;

[0057] According to the corresponding relationship between the device physical logic model IPD, the intelligent electronic device IED capability description model ICD and the protection logic diagram model elements, the association between the protection logic diagram model and the IPD model and the ICD model is obtained;

[0058] According to the symbol template and elements, a protection logic diagram model is established based on the association.

[0059] Among them, the symbol templates of each logical symbol are established, including:

[0060] Use basic graphic elements to describe each logic symbol, create input and output connection point information for each logic symbol, and set the properties of each logic symbol;

[0061] Model elements are used to construct symbol templates to describe the logical symbols. Specifically, the SymbolTemplate element is used to construct the symbol template, which includes a Terminals element, a Caption element, a Shape element, and a Properties element. The SymbolTemplate element uniquely identifies the symbol using the id attribute, identifies the symbol type using the type attribute, and represents the height and width of the symbol using width and height.

[0062] Among them, the types of symbols include input and output symbols, logic symbols, triggers, comparison operators, mathematical operators, mathematical function operators, startup elements, etc. Among them, input and output symbols are used to associate IPD, ICD, constants, etc., logic symbols and trigger symbol types are used to process digital inputs, comparison operators, mathematical operators, and mathematical function operator symbols are used to process analog inputs, and the startup element, as a special element, represents whether the protection function of the device is activated.

[0063] Among them, the protection logic diagram model elements are defined, including:

[0064] The model element is used to represent the protection function logic scene, and the attributes of the logic scene include the scene name, size, and background color bkColor.

[0065] Specifically, the LogicScene element is used to represent the protection function logic scene. The LogicScene element includes attributes such as the scene name, size, and background color bkColor. The functional logic scene represents all graphics composed of a set of protection logic symbols and graphic attributes such as canvas, and also includes the corresponding logical connection relationships. Symbol is a symbol element, which is an instantiation of the SymbolTemplate element. The attributes are the same as the template by default, and can also be instantiated in a displayed manner. The Line element represents the connection, which graphically and logically expresses the connection of the protection logic diagram.

[0066] Furthermore, the LogicScene element contains two or more Symbol elements and one or more Line elements. Therefore, Symbol elements can be used to represent symbols, inputs, outputs, and various operators. The LogicScene element includes attributes such as the scene name, size, background color (bkColor), and type. When the Logic type is composite, it indicates a composite signal; when type is plg, it indicates a primary protection logic diagram.

[0067] Furthermore, the Symbol element contains attributes such as name, pos, size, template ID, target output information, and source input information. The ID attribute uniquely identifies the associated SymbolTemplate, the target attribute is used to output the symbol's associated IPD, ICD, constant, and other signals, and the source attribute is used to input the symbol's associated IPD, ICD, constant, and other signals.

[0068] Furthermore, the connection points of the protected logical diagram are represented by Line. The Line element contains the style attributes of the connection and the symbolic connection point information of the start and end points. Specifically, the startSymbolName, startSymbolPoint, endSymbolName, and endSymbolPoint attributes can be used to represent the symbolic information of the start and end points. The Line element contains style attributes such as size, linecolor wire color, linwidth wire width, and linstyle wire style. The style elements of Line generally use the default, and the corresponding attributes can be modified if there are special needs. Line contains two or more CornerPoint elements, and the coordinate information of Line is represented by the CornerPoint element. The CornerPoint element represents the path coordinates of the Line element from the start point to the end point, and contains two attributes, x and y.

[0069] Among them, the association between the protection logic diagram model and the IPD model and the ICD model refers to the association of the protection logic diagram model with the IPD model and the ICD model through input symbols or output symbols. The input symbol is associated with the IPD model and the ICD model through the source attribute, and the output symbol is associated with the IPD model and the ICD model through the target attribute.

[0070] Specifically, the correspondence between the device physical logic model (IPD) and the protection logic diagram model elements involves associating functional elements in the device physical logic model (IPD), such as switch outputs and analog quantities, with input or output symbols of the protection logic diagram model elements. The associated IPD information includes hard pressure plate signals, analog quantity signals, hard contact output signals, etc. The relative path of elements in the IPD model is used for association, such as device board / functional element, and this path can be used to index unique elements in the IPD model.

[0071] Specifically, the correspondence between the IED capability description model (ICD) and the protection logic diagram model elements involves associating GOOSE, SV, control words, and fixed values ​​in the ICD capability description model with the input or output symbols of the protection logic diagram model elements. Associated ICD model elements include fixed values, control words, soft pressure plates, functional status, and other objects. The physical addresses of ICD model elements are used for association, and the physical addresses can be used to index unique elements in the ICD model.

[0072] In particular, the input symbols of the protection logic diagram model can be associated with Boolean values, constants, and composite signals in addition to IPD model and ICD model elements.

[0073] The protection logic diagram model is established based on the symbol templates and elements, including using XML format, using defined symbols, connections, and other elements, and using composite signal construction, symbol template reference, and other methods to describe the protection logic diagram within the protection logic diagram scenario based on the position, size, and connection relationship of the protection logic symbols. The root element of the constructed protection logic diagram model is PLG, which contains one IED element and one SymbolTemplates element. The IED element contains one or more LogicSence elements, which contain two or more Symbol elements and one or more Line elements. The Line element contains two or more CornerPoint elements. The SymbolTemplates contains one or more SymbolTemplate elements.

[0074] The composite signal construction approach involves describing complex signals using the same methods as protection logic diagram models. The resulting output can be used as input for other protection logic diagram models. Complex signals, typically composed of multiple signals, such as CT disconnection or current flow, require synthesis. The resulting signal can then be used as input for other logic configuration diagrams, associating it with the input symbol of the protection logic diagram through the source attribute.

[0075] The symbol template reference method is used, including referencing and instantiating the SymbolTemplate symbol template through the template id attribute of the Symbol element when generating the protection logic diagram. Symbol contains all the properties of SymbolTemplate and has the project instantiation property.

[0076] The present invention is further described in detail below with reference to the accompanying drawings and examples.

[0077] The embodiment of the present invention provides a model construction and association method for protecting logic diagrams. Figure 1 Steps for its implementation.

[0078] Step 1: Extract various logical symbols from the protection logic diagram and create corresponding symbol templates.

[0079] Extract the input and output symbols, logical symbols, triggers, comparison operators, mathematical operators, mathematical function operators, and startup elements of the protection logic diagram, describe the symbols through basic graphic elements, create input and output connection point information for various symbols, and set the symbol's name, description, type and other attributes.

[0080] Unified construction rules are formulated for various graphic symbols to ensure the accuracy of coordinates and descriptions within the graphic symbols. Some examples of graphic symbol templates are shown in Table 1. The construction of symbol templates should comply with the following rules:

[0081] 1) Input / output graphic symbols default to 20cm high and 60cm wide. Symbols with two inputs and one output are 60cm high and 40cm wide, while symbols with three inputs are 80cm high and 40cm wide. The height increases by 20cm for each additional input or output, and so on.

[0082] 2) The coordinates of the connection points are located at equally spaced points on both sides of the symbol. For example, the two input connection points are located at the 1 / 3 and 2 / 3 positions, respectively, and the output connection point is located at the 1 / 2 position. The coordinates of the connection points are similar and are not described when describing graphic symbols.

[0083] 3) If the symbol types are the same but the number of connection points is different, the symbols are expanded according to the rules in 2) and 3). When building the library, the names are named in the format of "original name_input_output". For example, logic_gate_xor has two inputs and one output by default. If the symbol is expanded to 4 inputs and 1 output, the new symbol name is named "logic_gate_xor_4_1".

[0084] 4) The graphic center point of the symbol template should be at the geometric center point of the symbol, and should not be misplaced.

[0085] Table 1 Examples of some graphic symbol templates

[0086]

[0087] Step 2: Define the protection logic diagram scenario and attributes, and define the symbols and graphic connections of the protection logic diagram.

[0088] The protection logic diagram model expresses logical topology relationships by connecting Lines and Symbols. Line elements represent the start and end symbol information of a connection. Symbol elements and their connection points reference the SymbolTemplate through the ID attribute. Symbols contain all the properties of the SymbolTemplate and have project instantiation properties.

[0089] Protection scenarios are divided into two types: protection logic diagrams and composite signals. Both methods use the same description method: drawing the logic diagram through symbolic reference instantiation and connection. The default size of the logic scene is {800cm, 600cm}, and the default background color is (A:255, R:255, G:255, B:255). The protection logic diagram logic scene elements are constructed as follows:

[0090] <LogicScence name="Test Scenario" size="Size(800, 600)" bgColor="Color(255, 255, 255, 255)" type="plg">

[0091] When a connection element is created, the various style attributes are default. If there are special requirements, the style of the connection can be set by setting the corresponding attribute values. A connection is identified by two or more corner point coordinates for various turning points of the connection. The starting corner point coordinates identify the start of the connection, and the ending corner point coordinates identify the end of the connection. An example of creating a connection element is as follows:

[0092] <Line name="line1" pos="Point(0, 0)" size="Size(0, 0)" startSymbolName="S1" startSymbolPoint="1" endSymbolName="S4" endSymbolPoint="1">

[0093] <cornerpoint> Point(445,205)< / cornerpoint>

[0094] <cornerpoint> Point(500,205)< / cornerpoint> <s

[0095]

[0096] The symbol "Symbol" references the symbol template by its id, and determines the specific position of the symbol in the protection logic diagram by instantiating the coordinates. The coordinates are centered on the symbol's center, and the default size of the symbol is (60, 20). The output of the symbol is associated through the "target" attribute, and the input of the signal is associated through the "source" attribute. In addition to referencing IPD model elements, ICD model elements, boolean quantities, and analog quantities, the signals of the symbol can also be associated with the aforementioned composite signals. An example of creating a symbol is as follows:

[0097] <Symbol name="S2" id="io_dinput" pos="Point(325, 195)" size="Size(60, 20)" source="E[%type%]C1[%address%]A-phase current operation[%desc%]" / >

[0098] <Symbol name="S3" id="io_doutput" pos="Point(530, 205)" size="Size(60, 20)" target="B02.GSLogicLinkMult1.out1[%address%]Protection trip[%desc%]" / >

[0099] Step 3: Analyze the corresponding relationship between the IPD model, ICD model and protection logic graph model elements, and establish the association between the protection logic graph model (PLG) and the IPD model and ICD model.

[0100] The protection logic diagram model is based on the correspondence between the input or output symbols and the IPD model and ICD model, such as Figure 3 As shown in Figure 2. Input symbols are associated with other models through the source attribute, and output symbols are associated with other models through the target attribute.

[0101] The source attribute of the Symbol element cannot be empty when the symbol is of input type. The source attribute represents the association between the input symbol of the protection logic diagram model and various models. The specific association format of the source attribute is: "I[%type%]ZZZJ:B01.SyncTime.signal_err[%address%]0[%desc%]", which consists of four parts. The first part is the signal type, the identifier is [%type%], and the specific model type is the previous character. The signal type is an enumeration type: P process, I internal, constant C, startup element Q, L indicates reference to IPD model, D is reference to ICD model, and E is reference to other composite signals. The second part is the signal address, the identifier is [%address%], which represents the address of the signal. When referencing a composite signal, it is the name of the composite signal logic scenario; for the ICD model, it refers to the physical address of DO or DA; for the IPD model, it is the path address of IPD, referenced in the Device.SubDevice / Component format; for digital constants, it is generally an integer, and for analog quantities, it is generally a floating point type. The last identifier [%desc%] represents the Chinese description of the signal and can be empty.

[0102] The target attribute of the Symbol element cannot be empty when the symbol is of output type. The target attribute element represents the association between the output of the protection logic diagram model and various models. The specific association format of target is: "B01.C1R2.yk03.ind_close[%address%] remote control 03[%desc%]". The target signal consists of two parts. The first part is the signal address, and the identifier is [%address%]. When associated with the ICD model, it references the physical address of the DO or DA; when associated with the IPD model, it is the element relative path address, and is referenced in the Device.SubDevice / Component format. The second part is the signal description, identified by [%desc%], which can be empty.

[0103] Step 4: Based on the integration of symbol templates, graphic connections, model associations, etc., a protection logic diagram model is established through composite signal construction and symbol template reference.

[0104] The protection schematic model structure is as follows Figure 2 As shown, the root element is the PLG element, which contains 1 IED element and 1 SymbolTemplates element. The IED element contains 1 or more LogicSence elements, and the LogicSence element contains 2 or more Symbol elements and 1 or more Line elements. The Line element contains 2 or more CornerPoint elements. The SymbolTemplates element contains 1 or more SymbolTemplate elements, and the SymbolTemplate element contains 1 Terminals element, Shapes element, Caption element, and Properties element. The Terminals element contains 2 or more Terminals. The Shapes element contains 0 or more Rectangle elements and Polygon elements. The Polygon element contains 3 or more Point elements. The Caption element contains 0 or more Text elements. Properties contains 1 or more Property elements. All elements of the model can be extended and privately defined through the Private element.

[0105] For each protection schematic, all involved graphic symbols are transformed and the corresponding models in the symbol library are extracted, such as Figure 4 shown.

[0106] Some complex signals are composed of many signals, such as CT disconnection, flow or no flow, etc., which require the synthesis of multiple signals. The synthesized signal can be used as the input of other logic configuration diagrams. Figure 5 In the protection logic diagram model, the protection tripping signal is the output of the synthetic signal, and can also be used as the input of the protection logic diagram model and associated with other protection logic diagram models.

[0107] Based on symbol templates, connections, model associations, etc., the topological relationship of the protection schematic is expressed by connecting Line and Symbol types and connection points. The Line element expresses the starting and ending symbol connection information of the connection, such as Figure 6 As shown, Line 1 indicates a connection between point 1 of the S1:io_dinput element and point 1 of the S4:logic_gate_and element. S2:io_dinput is a composite signal, representing a reference to the composite signal of the phase A operating current. The Symbol element and its connection points reference a symbol template. Figure 6 The corresponding protection logic diagram model example is as follows:
