[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following describes a method and device for graphical configuration modeling of relay protection setting items according to an embodiment of the present invention with reference to the accompanying drawings. First, the method for graphical configuration modeling of relay protection setting items according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0030] Figure 1 It is a flow chart of the method for graphical configuration modeling of relay protection setting items according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the relay protection setting item graphical configuration modeling method includes the following steps:

[0032] In step S101, a correspondence between fixed values ​​and setting principles and formulas is established.

[0033] Furthermore, in one embodiment of the present invention, a correspondence between fixed values ​​and setting principles and formulas is established, including: establishing multiple fixed value item templates based on the fixed value items, wherein the content of each template in the multiple fixed value item templates generates at least one setting principle description and corresponding formula entry according to the number of entered setting principles.

[0034] It can be understood that the corresponding relationship between the setting value and the setting principle and formula is established, and the relationship between the setting principle and formula and the protection setting value is as follows: Figure 2 As shown in the figure, for different setting items, the number of principle formulas may be different. Some setting items correspond to a single principle and formula, while some setting items correspond to multiple principles and formulas. In order to distinguish different protection setting items, different setting item templates can be established by taking the setting items as references. Before adding setting principles and formulas, set the setting item templates first. When adding setting items, select different setting item templates, such as Figure 3 As shown, the fast configuration of the fixed value item information is realized, the possible errors in the configuration are reduced, and the speed of fixed value item modeling is greatly improved.

[0035] The content of the fixed value item template is to automatically generate n setting principle descriptions and corresponding formula entry boxes according to the number of setting principles (n) entered. Since the fixed value items mostly correspond to 1 setting principle, 2 setting principles, and 3 setting principles, the system comes with the above three templates, which can be used directly. The fixed value single templates for other number of setting principles can be established according to the custom content.

[0036] In step S102, a data dictionary index table of fixed value items is established according to the corresponding relationship between fixed values ​​and setting principles and formulas.

[0037] It is understandable that in the application system development process of the prior art, the application program and the underlying database are tightly coupled, and the database operation statements in the program are statically encapsulated in the program and are closely integrated with specific data table structures or fields. When the system changes, the database structure has to be redesigned to adapt to the changes in new requirements.

[0038] Therefore, an embodiment of the present invention establishes a fixed value item data dictionary index table to record the hierarchical relationship between fixed value items and setting principles and formulas, as well as the operation object table structure information. The index table is used to release the binding relationship between the program and the database, reduce the coupling degree, and improve the functional scalability and reuse.

[0039] In step S103, according to the data dictionary index table and the selected fixed value item template, a fixed value item setting formula is established based on the graphic configuration package to complete the fixed value item modeling.

[0040] Furthermore, in one embodiment of the present invention, a setting formula for a fixed value item is established based on a data dictionary index table and a selected fixed value item template and based on a graphic configuration package to complete fixed value item modeling, including: utilizing a fixed value item template selected from a plurality of fixed value item templates, maintaining its corresponding setting principles and formulas, and establishing setting principles and corresponding formulas for corresponding fixed value items according to the relay protection fixed value setting regulations, wherein principle information is entered into the corresponding fixed value item template to establish the setting principle, and a setting calculation formula is established based on the MathType graphical component.

[0041] That is to say, in an embodiment of the present invention, based on the selected fixed value item template, its corresponding setting principles and formulas are maintained, and the setting principles and formulas correspond one to one. The setting principles and corresponding formulas of the corresponding fixed value items are established according to the relay protection fixed value setting procedures. The setting principles can be established by directly entering the principle information in the corresponding fixed value item template, and the setting calculation formula is established based on the MathType graphical component.

[0042] In addition, in one embodiment of the present invention, a setting calculation formula is established based on the MathType graphical component, including: encapsulating the setting variables, logical operation relationships of multiple setting formulas, and numerical operation relationships through the MathType graphical component, and representing them with corresponding symbolic icons, and at the same time establishing the variables involved in the setting principles in the MathType graphical component.

[0043] For example, the MathType graphical component encapsulates the logical operation relationships and numerical operation relationships of setting variables and various setting formulas, and represents them with corresponding symbol icons, including taking the maximum value (icon represented by max), taking the minimum value (icon represented by min), taking the absolute value (icon represented by abs), conditional value (icon represented by if), rounding (icon represented by int), logical OR (icon represented by or), logical AND (icon represented by and), rounding function (icon represented by round), etc., as well as operators related to numerical operation relationships, such as addition (icon represented by +), subtraction (icon represented by -), multiplication (icon represented by ×), division (icon represented by ÷), brackets (icon represented by ()), greater than (icon represented by >), less than (icon represented by <), greater than or equal to (icon represented by ≥), less than or equal to (icon represented by ≤), not equal to (icon represented by ≠), square (icon represented by x 2 ), cubic (icon represents x 3 ), square root (icon represented by √), sine and cosine function (icon represented by sin), cosine function (icon represented by cos), inverse tangent function (icon represented by arctan), etc., constant values ​​such as pi (icon represented by π). At the same time, the variables involved in the setting principle are established in the MathType graphical components, such as reliability coefficient class (icon represented by Kk), sensitivity coefficient class (icon represented by Klm), measurement impedance class (icon represented by Zcl), branch coefficient class (icon represented by Kfz), fault voltage class (icon represented by U), fault current class (icon represented by I), etc.

[0044] When modeling fixed-value items, you can directly use the corresponding functions and variable icons of MathType graphical components, and apply the encapsulated functions to the establishment of setting formulas. It is simple, efficient and not prone to errors. Especially for the problems of complicated modeling of fixed-value items, inconvenient use, and the need to maintain code scripts, the characteristics of MathType graphical components are fully combined to display complex modeling code programs graphically. The modeling of fixed-value items can be completed with simple operations, freeing users from complex programming and modeling, greatly improving the efficiency of fixed-value item modeling.

[0045] Specifically, the technical problems that the fixed value item modeling process of the prior art is cumbersome, prone to errors and requires staff to have a certain code foundation have not been solved. The embodiment of the present invention determines the relationship between the fixed value items of relay protection and the setting principles and formulas, establishes a data dictionary index table, selects an existing fixed value item template or establishes a custom fixed value item template, establishes a fixed value item setting formula based on the setting variable information, logical operation relationship, numerical operation relationship, etc. encapsulated in the graphic configuration, completes the fixed value item modeling work, and comprehensively improves the efficiency of the fixed value item modeling work. The embodiment of the present invention is simple to use, efficient and not prone to errors.

[0046] The working principle of the method in the embodiment of the present invention is described in detail below with a specific embodiment.

[0047] like Figure 4 As shown, the method of the embodiment of the present invention includes:

[0048] Step S0: Start.

[0049] Step S1: Determine the set of all constant value items that need to establish a model.

[0050] For example, determine the set A of all constant-value items that need to be modeled, and let A = {s1, s2, ..., s n}, where s1 to s n is the fixed value item that needs to be modeled.

[0051] Step S2: Establish a constant value item modeling index table.

[0052] Based on the relay protection setting calculation procedures, a fixed value item data dictionary index table is established to record the correspondence between the fixed value items and the setting principles and formulas as well as the operation object table structure information. The binding relationship between the program and the database is released through the index table.

[0053] Step S3: Select any fixed-value item from the set for modeling.

[0054] For example, select a fixed value item s from the set A in order i Data modeling (s i is any value item to be established).

[0055] Step S4: Select a fixed value item template according to the corresponding relationship between the fixed value item and the setting principle and formula.

[0056] In order to distinguish different protection setting items, different setting item templates are established, and the setting item corresponding template is selected according to the correspondence between the setting item and the setting principle and formula, so as to realize the rapid configuration of the setting item information.

[0057] Step S5: Enter the setting principle description in the setting instructions.

[0058] That is, enter the setting principle description in the setting instructions of the fixed value item template.

[0059] Step S6: In the formula box, select the formula variables and operation logic icons corresponding to the setting principle to edit the setting formula.

[0060] In the setting formula of the constant value item template, select the corresponding setting description variables and operation logic icons to complete the editing of the setting calculation formula.

[0061] Step S7: After the fixed value item is established, the established fixed value flag is set to 1, and the fixed value item is removed from the fixed value item combination.

[0062] It can be understood that after the fixed value item is established, the established fixed value flag is set to 1, and the fixed value item s is removed from the fixed value item set A. i .

[0063] Step S8: Determine whether the set of fixed value items is empty.

[0064] That is to say, determine whether the fixed value item set A is empty. If so, jump to step 9, otherwise jump to step S3.

[0065] Step S9: End.

[0066] In summary, the graphical configuration modeling method for relay protection setting items in the embodiment of the present invention realizes the rapid development of application systems based on graphical configuration as a human-computer interaction tool of general configuration software. Graphic component modeling draws on some processes in UML (Unified Modeling Language) to establish models, applies data dictionary index tables, and realizes a full set of mapping mechanisms from objects to database tables, which can improve the flexibility of queries and can be reused many times. In addition, the function implementation process and storage modules are combined in a building block manner. The interface operation is simple, the control resources are rich, and can be reused, which reduces the waste of system resources and is simple to operate.

[0069] like Figure 5 As shown, the relay protection setting item graphic configuration modeling device 10 includes: a first establishing module 100, a second establishing module 200 and a modeling module 300.

[0070] Specifically, the first establishing module 100 is used to establish a corresponding relationship between a fixed value and a setting principle and formula.

[0071] The second establishing module 200 is used to establish a data dictionary index table of fixed value items according to the corresponding relationship between fixed values ​​and setting principles and formulas.

[0072] The modeling module 300 is used to establish a setting formula for the set value item according to the data dictionary index table and the selected set value item template and based on the graphic configuration package to complete the set value item modeling.

[0073] Furthermore, in one embodiment of the present invention, the second establishing module 200 is specifically used to establish multiple fixed value item templates based on the fixed value items, wherein the content of each template in the multiple fixed value item templates generates at least one setting principle description and corresponding formula entry according to the number of entered setting principles.

[0074] Furthermore, in one embodiment of the present invention, the modeling module 300 is specifically used to utilize a fixed value item template selected from a plurality of fixed value item templates to maintain its corresponding setting principles and formulas, and to establish setting principles and corresponding formulas for corresponding fixed value items according to the relay protection fixed value setting procedures, wherein principle information is entered in the corresponding fixed value item template to establish the setting principle, and a setting calculation formula is established based on the MathType graphical component.

[0075] Furthermore, in one embodiment of the present invention, the modeling module 300 is further used to encapsulate the setting variables, logical operation relationships of various setting formulas, and numerical operation relationships through MathType graphical components, and represent them with corresponding symbolic icons, and at the same time establish the variables involved in the setting principles in the MathType graphical components.
