[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] In one embodiment, Figure 1 As shown, a data processing method for multi-physics field calculation software of power equipment is provided. This embodiment takes the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0049] Step S101, obtaining a simulation data set of a simulation model of an electric power device.

[0050] Among them, the simulation data set of the simulation model of the power equipment may include a variety of simulation data of the simulation model, such as but not limited to the mesh data, geometry data, material property data, constraint data, load data, excitation data, connection relationship data, unit attribute data, etc. of the model. Among them, the mesh data can be used to describe the discretization results of the model, such as unit type, node distribution, etc., the geometry data can include the geometry, size and topological relationship of the model, etc., the material attribute data can include physical properties of the model material such as density, elastic modulus, conductivity, etc., the constraint data can include displacement boundary conditions, temperature fixed values, potential constraints, etc., the load data and excitation data can include, for example, external forces, heat sources, electromagnetic excitations, etc. of the model, the connection relationship data can include the interaction between physical fields, such as the interface connection of fluid-solid coupling, the power exchange of electrothermal coupling, etc., and the unit attribute data can include additional information that the solver may need, such as nonlinear material models, eddy current unit parameters, etc.

[0051] Exemplarily, the terminal can obtain the simulation data of the simulation model input by the user through the graphical interface to obtain the simulation data set. Exemplarily, the terminal can also obtain the simulation data set of the simulation model by running a script file provided by the user.

[0052] Step S102, according to the applicable relationship between each type of data in the simulation data set and each physical field, the general data in the simulation data set is stored in a general database, and the exclusive data corresponding to each physical field in the simulation data set is stored in an exclusive database corresponding to the physical field.

[0053] Specifically, for various types of data in the simulation data set, they can be classified as general data or exclusive data corresponding to a certain physical field according to the applicable relationship between each type of data and different physical fields. General data can be applicable to multiple physical fields, and it does not change with the change of the physical field in multi-physical field simulation. Exemplarily, general data can include but are not limited to mesh data, geometric data, material property data, etc. Exemplarily, the exclusive data of the physical field can include but are not limited to the data applicable to the physical field, which are closely related to the characteristics of the physical field. Exemplarily, the exclusive data of the physical field can include but are not limited to the constraint condition data, load data, excitation data, connection relationship data, unit attribute data, etc. of the physical field. For example, the exclusive data corresponding to the electromagnetic physical field may include electromagnetic excitation data, and for another example, the exclusive data corresponding to the structural physical field may include data such as external force load data.

[0054] Among them, the terminal can pre-establish a general database for storing general data, and for multiple physical fields, respectively establish exclusive databases for storing their corresponding exclusive data. Among them, the general database and each exclusive database can set corresponding constraint rules according to the preset data format, so that the data stored therein can conform to the preset data format. Among them, the exclusive database corresponding to each physical field can be set according to the specific data requirements of the physical field. For example, specific data types, verification rules, etc. can be set for various exclusive data corresponding to the physical field to ensure the accuracy of the data description of the physical field. In this step, the general data in the simulation data set can be stored in the general database, and the exclusive data corresponding to each physical field can be stored in the exclusive database corresponding to the physical field.

[0055] Exemplarily, the terminal may use different labels to mark different physical fields, so that in this step, the exclusive database with the same label can be searched according to the label of the physical field corresponding to the exclusive data, and then the exclusive data can be stored in the exclusive database.

[0056] Optionally, when the simulation data set contains exclusive data corresponding to a physical field, and the terminal has not established an exclusive database for the physical field, a new exclusive database for the physical field can be created according to the data requirements of the physical field, and the exclusive data can be stored in the exclusive database.

[0057] Step S103, when performing simulation solution on the simulation model, according to the target physical field corresponding to the simulation solution, a physical field simulation data set of the target physical field is extracted from the general database and the exclusive database of the target physical field.

[0058] When it is necessary to simulate and solve the simulation model of the power equipment, the physical field simulation data set corresponding to the target physical field can be extracted from the general database and the exclusive database of the target physical field according to the target physical field involved in the simulation solution. In different simulation solution scenarios, the target physical field may include one or more physical fields, and the physical field simulation data set corresponding to the target physical field may include simulation data that can realize the simulation solution of the simulation model of the power equipment in the one or more physical fields.

[0059] Step S104, converting the physical field simulation data set into an input file that conforms to the input format of the target physical field solver for simulation solution.

[0060] It is understandable that the data format of each simulation data in the physical field simulation data set extracted from the general database and the exclusive database is the preset data format corresponding to the database. In this step, each simulation data can be converted according to the input format of the target physical field solver used for this simulation solution to obtain an input file that conforms to the input format. Exemplarily, in this step, a file template of the input file can be obtained according to the input format corresponding to the input file, and then the physical field simulation data sets are respectively inserted into the corresponding positions in the file template to obtain an input file that conforms to the input format.

[0061] For example, Figure 2 As shown, the terminal in this embodiment can be configured with a simulation database and a converter. A general database and exclusive databases corresponding to structural physics, fluid physics, and electromagnetic physics can be set in the simulation database. The general database can store mesh data, geometric data, material property data and other data in the simulation data set, the exclusive database corresponding to the structural physics field can store connection relationship data, constraint data and the like, the exclusive database corresponding to the fluid physics field can store boundary condition data and the like, and the exclusive database corresponding to the electromagnetic physics field can store excitation data and the like. When it is necessary to simulate and solve the simulation model, the physical field simulation data set can be extracted from the general database and the exclusive database of the target physical field according to the target physical field corresponding to the simulation solution, and then the physical field simulation data set can be converted into an input file that conforms to the input format according to the input format of the target physical field solver using the converter. As shown in FIG. Figure 2 As shown, the converter can convert data into files in various input formats including but not limited to .xml format, .cdb format, .bdf format, etc.

[0062] In the data processing method of the multi-physics field computing software of the above-mentioned power equipment, the common data shared between different physical fields is uniformly stored by using a general database, so that different physical fields can share a consistent data basis, reduce the complexity of maintaining redundant data, and provide a standardized basis for data sharing and coupling across physical fields; and by using the exclusive database corresponding to the physical field to store the exclusive data of the physical field, the exclusive data of the physical field can be standardized according to the differentiated data requirements of each physical field, so as to ensure the accuracy of the data description. At the same time, since the standardized storage of simulation data can be achieved by storing the simulation data in the general database and the exclusive database in this scheme, when the multi-physics field computing software is needed for simulation and solving, only one format conversion is needed to convert the physical field simulation data set into an input file that conforms to the input format of the target physical field solver, effectively reducing the redundant work and error risks caused by inconsistent data formats. Moreover, the data storage and format conversion method in this scheme has high flexibility and scalability, and can be flexibly compatible with new physical fields or solvers, which is conducive to complying with the development trend of multi-physics field simulation technology penetrating into a wider field, and providing long-term support for the growing simulation needs.

[0063] In an exemplary embodiment, Figure 3 As shown, converting a physics simulation data set into the input format of a target physics solver for simulation may include:

[0064] Step S301, obtaining the supported input format of the target physics field solver.

[0065] When converting a physical field simulation data set into an input format of a target physical field solver, the supported input format of the target physical field solver to be used may be firstly obtained.

[0066] Each solver may have one or more supported input formats. When an input file corresponding to one of the supported input formats of the solver is input to the solver, the solver may parse it and extract corresponding data for simulation solution. It is understood that if the input file input to the solver does not conform to any of the supported input formats, the solver cannot process the input file.

[0067] After obtaining the supported input format of the target physical field solver, it can be determined whether the supported input format includes the preset first file format, and if so, step S302 can be executed, otherwise, step S303 can be executed.

[0068] Step S302: if the supported input format includes a preset first file format, the physical field simulation data set is converted into an input file in the first file format.

[0069] Among them, when the supported input format of the target physical field solver includes the first file format, the physical field simulation data set can be preferentially converted into an input file of the first file format. Optionally, the first file format can be an Extensible Markup Language (XML), which is a markup language for representing structured data, has good readability and flexibility, and is widely used for data storage and transmission. Optionally, the terminal can pre-set a converter that converts data in a general database and a proprietary database into different file formats, and the converter can be configured with data conversion rules corresponding to the data in the database and the first file format.

[0070] Step S303: if the supported input format does not include the first file format, converting the physical field simulation data set into an input file of the second file format according to the second file format included in the supported input format.

[0071] Among them, when the supported input format of the target physical field solver does not include the first file format, the second file format included in the supported input format can be obtained, and the physical field simulation data set can be converted into an input file of the second file format. Optionally, after determining that the supported input format does not include the first file format, the terminal can determine whether the supported input format of the target physical field solver contains a file format that its converter already supports for conversion. If so, the format can be used as the second file format. When all the file formats included in the supported input format do not match the file formats supported by the converter for conversion, a format can be selected from the supported input format as the second file format, and a data conversion rule corresponding to the second file format can be added to the converter. Then, the converter can be used to convert the physical field simulation data set into an input file of the second file format.

[0072] In this embodiment, when converting the physical field simulation data set into an input file, it is preferentially determined whether the target physical field solver supports the first file format, and if it is determined that it supports it, the physical field simulation data set is preferentially converted into an input file of the first file format. According to the universality of various file formats in different solvers, a format with higher universality can be selected as the first file format, thereby saving the development of format conversion interfaces for other file formats, which is conducive to improving processing efficiency.

[0073] In an exemplary embodiment, obtaining a simulation data set of a simulation model of an electrical device may include: displaying a visual input interface for simulation model data; obtaining a simulation data set in response to a parameter input operation based on the visual input interface; or, obtaining a data input script file for the simulation model; and obtaining a simulation data set based on the data input script file.

[0074] Among them, the terminal can obtain the simulation data set of the simulation model of the power equipment in a variety of different ways.

[0075] Optionally, the terminal may display a visual input interface for simulation model data, and the visual input interface may include interactive controls for inputting simulation data of the simulation model. The user may perform parameter input operations by interacting with the interactive controls in the visual input interface. Exemplarily, the visual input interface may include multiple input boxes, each of which may be used to input a type of simulation data of the simulation model, and the terminal may obtain the data input by the user in each input box, and obtain a simulation data set based on the data.

[0076] Optionally, the terminal may also obtain a data input script file provided by the user, and obtain simulation data of the simulation model by running the script file, and obtain a simulation data set based on the data. Exemplarily, the data input script file may include multiple simulation data of the simulation model, or may include data source information that can obtain multiple simulation data of the simulation model. By running the script file, the terminal may directly obtain multiple simulation data of the simulation model, or may obtain multiple simulation data of the simulation model from the corresponding data source.

[0077] In this embodiment, by providing the user with a data input method through a visual interface or using a script, the actual needs of different users for data input can be flexibly met, which is conducive to improving the data acquisition efficiency of the simulation data set.

[0078] In an exemplary embodiment, Figure 4 As shown, obtaining a simulation data set of a simulation model of an electric power device may include:

[0079] Step S401, obtaining a data input file of a simulation model.

[0080] In this embodiment, the user can provide a data input file to the terminal so that the terminal can obtain the simulation data set of the simulation model that needs to be input. The data input file can include multiple simulation input data of the simulation model, and these data can be represented in a structured or semi-structured form.

[0081] Step S402: extracting multiple pieces of simulation input data contained in the data input file according to the file format of the data input file.

[0082] The terminal can identify the file format of the data input file, and then parse the data input file using a parsing method corresponding to the file format, and extract various simulation input data contents contained therein.

[0083] Among them, different from obtaining user input data through a visual input interface, or directly importing data through a data input script file, etc., which can directly import data that meets the format requirements of the simulation data set, the data input file may come from a variety of different simulation processing tools, so the data format corresponding to the simulation input data extracted from the data input file may not meet the format requirements of the simulation data set, making it difficult to directly obtain a simulation data set based on the simulation input data. Based on this, after extracting multiple simulation input data from the data input file, it can be first determined whether the data format of each simulation input data meets the first data format corresponding to the simulation data set. If it meets, step S303 is executed, otherwise step S304 is executed.

[0084] Optionally, the first data format corresponding to the simulation data set may include data types, data fields, data lengths, constraints, etc. corresponding to different simulation data. Exemplarily, the terminal may determine whether each simulation input data conforms to the first data format corresponding to the simulation data set.

[0085] Step S403: if the data formats corresponding to the multiple simulation input data conform to the first data format corresponding to the simulation data set, a simulation data set is obtained according to the simulation input data.

[0086] If the data format corresponding to the simulation input data conforms to the first data format corresponding to the simulation data set, the simulation data set can be directly obtained according to the multiple simulation input data.

[0087] Step S404: if the data format is not the first data format, then according to the data mapping relationship between the data format and the first data format, each simulation input data is converted into simulation data conforming to the first data format.

[0088] Among them, the terminal can pre-store data mapping rules between various data formats and the first data format according to the data mapping relationship between various data formats and the first data format for the data formats commonly used by the simulation input data, so that the simulation input data can be directly format converted according to the mapping rules to obtain simulation data that conforms to the first data format.

[0089] Exemplarily, the data mapping relationship between the data format and the first data format may include field mapping, data type mapping, data value mapping, etc. For example, assuming that the data field of a simulation input data item is "A" and the data value is "123", and according to the first data format requirement of the simulation data set, the data field corresponding to the data should be "B", then in this step, according to the field mapping relationship between the data format of the simulation input data and the first data format, the simulation input data can be converted from "A: 123" to "B: 123". For another example, assuming that the data content of a simulation input data item is "yes / no", and the first data format of the simulation data set requires "1 / 0" to represent the same information, then in this step, according to the data value mapping relationship between the data format of the simulation input data and the first data format, the simulation input data can be converted from "yes / no" to "1 / 0".

[0090] Step S405, obtaining a simulation data set according to each simulation data.

[0091] After each simulation input data is converted into simulation data conforming to the first data format, a simulation data set can be obtained according to the simulation data.

[0092] In this embodiment, by providing the user with a data input file to input data of the simulation model, the user can directly import files from various simulation processing tools to avoid repeated data processing. Among them, after obtaining the simulation input data in the data input file, checking whether its data format conforms to the first data format of the simulation data set, and converting the format when it does not conform, the smooth import of the simulation data can be guaranteed, and the uniformity of various simulation data in the database can be maintained, providing a stable data foundation for subsequent cross-physical field data sharing and coupling.

[0093] In an exemplary embodiment, Figure 5 As shown, the method may also include:

[0094] Step S501, inputting the input file into the target physical field solver, and obtaining the solution result output by the target physical field solver.

[0095] After the physical field simulation data set is converted into an input file conforming to the input format of the target physical field solver for the simulation solution, it can be input into the target physical field solver, and the target physical field solver performs simulation solution of the simulation model of the power equipment according to the data in the input file. Then, the solution result output by the target physical field solver can be obtained.

[0096] The solution result output by the target physical field solver may be a data file. After obtaining the solution result, it may be determined whether the file format of the solution result is a preset first file format. If so, step S502 may be executed, otherwise, step S503 may be executed. Optionally, the first file format may be an Extensible Markup Language (XML) format.

[0097] Step S502: if the file format of the solution result is the preset first file format, the solution result is parsed and visual information of the solution result is displayed.

[0098] Wherein, when the file format of the solution result is the first file format, the solution result can be parsed and converted into visual information according to the parsing method corresponding to the first file format, and then the visual information can be displayed. For example, the visual information of the solution result can include but is not limited to field distribution information, frequency response curve, etc.

[0099] Step S503, if the file format of the solution result is not the first file format, the solution result will be converted into the first file format according to the data mapping relationship between the second file format corresponding to the solution result and the first file format, and the solution result will be parsed and the visual information of the solution result will be displayed.

[0100] Among them, when the file format of the solution result is not the first file format, the terminal can obtain the second file format corresponding to the solution result, and convert the solution result into a file that conforms to the first file format according to the data mapping relationship between the second file format and the first file format. Then, the parsing method corresponding to the first file format can be used to parse the converted solution result and convert it into visual information, and then display the visual information. Exemplarily, the terminal can pre-set data conversion rules for various formats that do not belong to the first file format according to the file format of the solution result output by the commonly used solver of the simulation model of the power equipment, based on the data mapping relationship between the first file format and the various formats, so that after obtaining the solution result, the corresponding data conversion rules can be directly used for conversion processing.

[0101] In this embodiment, by obtaining the solution result output by the target physical field solver, and parsing the solution result when the file format is the first file format and displaying the obtained visualization information, and converting the solution result when the file format is not the first file format to obtain a solution result that conforms to the first file format, the same parsing method can be used to efficiently parse various solution results, which is beneficial to improving overall processing efficiency.

[0102] In an exemplary embodiment, the general data includes one or more of mesh data, geometric data, and material property data; the specific data of the physical field includes one or more of constraint data, load data, excitation data, connection relationship data, and unit property data corresponding to the physical field.

[0103] Among them, the general data may include one or more of mesh data, geometric data, and material property data, which do not change with the change of the physical field in the multi-physics field simulation. For example, mesh data can be used to describe the discretization results of the model, such as unit type, node distribution, etc., geometric data can include the geometric shape, size and topological relationship of the model, etc., and material property data can include physical properties of the model material such as density, elastic modulus, conductivity, etc.

[0104] Among them, the exclusive data of the physical field may include one or more of the constraint data, load data, excitation data, connection relationship data, and unit attribute data corresponding to the physical field, and the exclusive data of the physical field is closely related to the characteristics of the physical field. Exemplarily, the constraint data corresponding to various physical fields may include displacement boundary conditions, temperature fixed values, potential constraints, etc., load data and excitation data may include external forces, heat sources, electromagnetic excitations, etc., connection relationship data can be used to describe the interaction between multiple physical fields, such as interface connection of fluid-solid coupling, power exchange of electrothermal coupling, etc., and unit attribute data may include additional information that may be required by the solver corresponding to each physical field, such as nonlinear material model, eddy current unit parameters, etc. Among them, each physical field may correspond to one or more exclusive data.

[0105] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
