the second establishing module is used for establishing a data dictionary index table of the fixed value item according to the corresponding relation between the fixed value and the setting principle and the formula; and
and the modeling module is used for establishing a fixed value item setting formula based on graphic configuration package according to the data dictionary index table and the selected fixed value item template so as to complete fixed value item modeling.
6. The apparatus according to claim 5, wherein the second establishing module is specifically configured to establish a plurality of fixed-value item templates according to fixed-value items, and the content of each of the plurality of fixed-value item templates in the plurality of fixed-value item templates generates at least one setting rule description and corresponding formula entry according to the number of entered setting rules.
7. The apparatus of claim 6, wherein the modeling module is specifically configured to maintain the corresponding setting rules and formulas by using a constant item template selected from the plurality of constant item templates, and establish the setting rules and corresponding formulas of the corresponding constant item according to a relay protection constant value setting procedure, wherein principle information is entered into the corresponding constant item template to establish the setting rules, and a setting calculation formula is established based on a MathType graphical component.
8. The apparatus of claim 7, wherein the modeling module is further configured to encapsulate setting variables, logical operational relationships of multiple setting formulas, and numerical operational relationships through the MathType graphical component, and represent them with corresponding symbolic icons, and meanwhile establish variables involved in the setting rules in the MathType graphical component.
9. An electronic device, comprising: a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the relay protection setting item graph configuration modeling method according to any one of claims 1 to 4.
10. A non-transitory computer readable storage medium having a computer program stored thereon, wherein the program is executed by a processor to implement the relay protection setting item graph configuration modeling method according to any one of claims 1 to 4.
