However, the simulation software used in different physical fields in the prior art is different, and even the simulation software used in the same physical field may be different. This will lead to problems such as repeated and complex exchange of different file data, low efficiency, and large errors during the simulation and analysis calculation process of power equipment.

Due to the different simulation software used in different physical fields or in the same physical field, the data format is incompatible, resulting in complex data transmission, low efficiency and prone to errors.

[0060] Embodiment 1

[0061] Please refer to Figure 1 , a flow chart of an embodiment of a data interface control method adapted to multiple simulation tools provided by the present application, comprising steps S1 to S4;

[0062] Step S1, obtaining a data file generated by the power system, and parsing the data file into corresponding power equipment model variables and parameter variables;

[0063] It is understandable that when performing simulation analysis of power equipment, it is necessary to first obtain the data file generated by the power system, and identify the file type corresponding to the data file through control instructions, and save the file type. After confirming the file type corresponding to the data file, the data file can be parsed and read by calling the corresponding parsing program pre-set by the computer program to obtain the power equipment model variables and the parameter variables, and save them; wherein, the power equipment model variables and the parameter variables are in a unified format, and can be key-value pairs containing parameter types and corresponding values. In this step, the required target output file format, result report format, etc. can be determined. Exemplary but not limiting, step S1 can be implemented by Python programming language, by calling the mime library to identify the file type corresponding to the data file, when the identified file type is a .DAT file type, the .DAT file type will be saved, and jump to the corresponding .DAT parsing program compiled based on the pandas library to parse and read the data file corresponding to the .DAT file type, so as to obtain the power equipment model variables and the parameter variable key-value pair dictionary in a unified format.

[0064] It should be noted that the data file can be directly collected through existing technologies or directly input, and this application does not impose any restrictions.

[0065] It should be noted that file types include but are not limited to .DAT files, .SWI files, .RAW files, .DYR files, .CSV files, .XLS files, .XLSX files, and .XML and .E files of CIM models, etc. This application does not limit the specific file types.

[0066] It should be noted that the parsing methods include but are not limited to libraries or modules such as pandas, numpy, pypsse, PYCIM, and xml.erree.ElementTree.

[0067] It should be noted that the power equipment model variables and the parameter variables are all key-value pair dictionaries, where the parameter type is the key and the specific data of the parameter is the value. The power equipment model variables include but are not limited to generator dictionaries, load dictionaries, transformer dictionaries, line dictionaries, etc.; wherein the generator dictionary includes but is not limited to generator model, node type, connection object, rated power, reference voltage, active power, reactive power, internal reactance, stator resistance, excitation system parameters, speed regulator parameters and other key values; the load dictionary includes but is not limited to load type, connection object, active power demand, reactive power demand, power factor, load model, response speed and other key values; the transformer dictionary is shown in Table 1, including but not limited to connection object, transformation ratio, connection group, core loss per unit value, no-load current per unit value and other key values; the line dictionary includes but is not limited to connection object, length, unit impedance, unit reactance, rated power, rated voltage, shunt reactor and other key values.

[0069]

[0070] In this way, by parsing data files of different data types into corresponding types of power equipment model variables and parameter variables, different data files can be converted into power equipment model variables and parameter variables in a format of one type, which is convenient for subsequent simulation calculations of simulation software.

[0071] Step S2, converting the power equipment model variables and the parameter variables into power equipment model files and parameter files in corresponding data formats respectively;

[0072] It can be understood that after the acquired data file is converted into the power equipment model variables and the parameter variables in a unified format, the data format corresponding to the simulation software can be obtained through the instructions of the corresponding simulation software; and at the same time, a first mapping relationship is established between the power equipment model variables, the parameter variables and the data format corresponding to the simulation software, and the first mapping relationship is encapsulated into a first program module; and based on the first program module, the power equipment model file and parameter file corresponding to the data format of the simulation software are generated. Of course, since the data formats corresponding to each simulation software are inconsistent, a mapping relationship can be established between the power equipment model variables, the parameter variables and the data formats corresponding to several simulation software, and encapsulated into several program modules. After the simulation software is determined, the program module corresponding to the simulation software is directly called, and the input power equipment model variables and the parameter variables can be directly converted into power equipment model files and parameter files corresponding to the data format corresponding to the simulation software, without calling the program module corresponding to the non-corresponding simulation software. By way of example and not limitation, when the simulation software to be determined is BPA, the specific content of the input file and the data format of the parameters can be obtained through the BPA flow and stability manual (e.g., if the data format is F4.3, then

[12] in the input file means [0.012]). By analyzing the spaces, carriage returns and other characters between the parameters in the input power equipment model variables and parameter variables, it can be ensured that the power equipment model variables and parameter variables can be read, and data cards (one line of the .DAT file is one data card) can be added and modified in the power equipment model variables and parameter variables to generate power equipment model files and parameter files in the corresponding data format of BPA. Of course, the power equipment files and parameter files can also be integrated into one file to facilitate subsequent input into the simulation software.

[0073] It should be noted that the simulation software includes but is not limited to PSD-BPA, PSS / E, PSASP, DSP, etc., and this application does not impose any restrictions.

[0074] It should be noted that the data formats corresponding to various simulation software are different. For example, the calculation model of PSD-BPA only defines two-winding transformers. For three-winding transformers, they need to be converted into three two-winding transformers. The generator models only include classic models, dual-axis models with / without considering damping windings, and equivalent load models. The excitation system models are relatively rich. PSS / E defines two-winding and three-winding transformers, and the generator models are relatively rich. In addition to the above models, it also provides salient-pole machine / hidden-pole machine sub-transient models with exponential saturation curves, and hidden-pole machine sub-transient models considering stator transients. There are fewer types of excitation systems, but custom model functions are provided.

[0075] It should be noted that after the power equipment model file and the parameter file are generated, they can be imported into a simulation data folder under a specific path, wherein the specific path is the storage path in the parameter variable in step S1.

[0076] In this way, by converting the power equipment model variables and parameter variables into power equipment model files and parameter files corresponding to the simulation software format, it is convenient to perform simulation calculations on the converted power equipment model files and parameter files.

[0077] Step S3, calculating the power equipment model file and the parameter file through simulation software to obtain a simulation calculation result file;

[0078] It can be understood that after the power equipment model variables and the parameter variables are converted into power equipment model files and parameter files in corresponding data formats respectively, the power flow calculation program in the simulation software can be called through control instructions to perform power flow calculation on the power equipment model file and the parameter file to obtain a power flow result output file; then, the transient calculation program or short-circuit calculation program in the simulation software can be called through control instructions to simulate the power flow result output file to obtain the simulation calculation result file.

[0079] It should be noted that the flow calculation program will construct corresponding control instructions based on the simulation program, simulation data files and the storage path of the flow result output file. Generally speaking, a new process can be started in the python script, and the simulation program can be executed by calling the command line based on the subprocess module to control program operation, input, etc., and obtain output results. This application does not limit the calling module.

[0080] It should be noted that the control instructions mainly include but are not limited to initialization, reading files, running programs, saving calculation results, etc.; after initialization, the power equipment model file and the parameter file are read through a specific storage path, and the power equipment model file and the parameter file are written into the calculation library of the simulation software, and then the calculation program of the simulation software is called, and after the simulation calculation is completed, the simulation calculation result file is saved to the specific path, wherein the specific path is also the storage path in the parameter variable in step S1.

[0081] In this way, by calling the power flow calculation program, transient calculation program or short circuit calculation program in the simulation software, the power equipment model file and the parameter file can be quickly simulated and calculated, thereby improving the calculation efficiency.

[0082] Step S4: parsing the simulation calculation result file to obtain a target result file in a unified format.

[0083] It can be understood that after completing the simulation calculation through the simulation software, the simulation calculation result file can be parsed. Specifically, first, the target output file format corresponding to the data file is obtained; secondly, the simulation calculation result file is extracted based on the target output file format to obtain the output variable; thirdly, a second mapping relationship is established between the simulation calculation result file, the target output file format and the output variable, and the second mapping relationship is encapsulated into a second program module; finally, based on the second program module, a target result file in a unified format is obtained. Of course, a mapping relationship can also be established in advance between the simulation calculation result file, the target output file format and the output variable, and encapsulated into several program modules. When the simulation calculation result file is confirmed, the corresponding program module can be directly called to generate a target result file in a unified format.

[0084] It should be noted that when the data file is converted into the power equipment model variables and the parameter variables, the target output file format is clarified, so the target output file format can be directly obtained through the control instruction.

[0085] It should be noted that the simulation calculation result file can be analyzed through, but not limited to, libraries such as pandas and numpy to analyze the simulation output format of the simulation calculation result file, including the sorting of simulation data of each node, data format and result report, etc., which is conducive to the subsequent establishment of a mapping relationship between the target output format and the simulation output format and output variables.

[0086] It should be noted that the target result file in a unified format may be, but is not limited to, an EXCEL table, document, etc., and this application does not impose any restrictions.

[0087] In this way, by parsing the simulation calculation result files, the simulation calculation result files with the corresponding data format of the simulation software can be converted into target result files in a unified format according to the required format. The data generated by various simulation tools can be converted into a unified format to reduce the complexity of data integration and processing, thereby improving the efficiency of simulation analysis of power equipment.

[0088] The embodiment of the present application can convert different data files into power equipment model variables and parameter variables in a same format by parsing the acquired data files into corresponding power equipment model variables and parameter variables, thereby facilitating the subsequent simulation calculations of the simulation software; by respectively converting the power equipment model variables and parameter variables into power equipment model files and parameter files corresponding to the simulation software format, it is convenient to perform simulation calculations on the converted power equipment model files and parameter files, and obtain simulation calculation result files; by parsing the simulation calculation result files, the simulation calculation result files with the corresponding data format of the simulation software can be converted into target result files in a unified format according to the required format, and the data generated by multiple simulation tools can be converted into a unified format to reduce the complexity of data integration and processing, thereby improving the efficiency of power equipment simulation analysis.

[0109] The calculation module 03 is used to calculate the power equipment model file and the parameter file through simulation software to obtain a simulation calculation result file;

[0110] Specifically, the calculation module includes: a first calculation unit and a second calculation unit; the first calculation unit is used to call the power flow calculation program in the simulation software through control instructions, perform power flow calculation on the power equipment model file and the parameter file, and obtain a power flow result output file; the second calculation unit is used to call the transient calculation program or short-circuit calculation program in the simulation software through control instructions, simulate the power flow result output file, and obtain the simulation calculation result file.

[0111] It can be understood that after the power equipment model variables and the parameter variables are converted into power equipment model files and parameter files in corresponding data formats respectively, the power flow calculation program in the simulation software can be called through control instructions to perform power flow calculation on the power equipment model file and the parameter file to obtain a power flow result output file; then, the transient calculation program or short-circuit calculation program in the simulation software can be called through control instructions to simulate the power flow result output file to obtain the simulation calculation result file.

[0112] It should be noted that the flow calculation program will construct corresponding control instructions based on the simulation program, simulation data files and the storage path of the flow result output file. Generally speaking, a new process can be started in the python script, and the simulation program can be executed by calling the command line based on the subprocess module to control program operation, input, etc., and obtain output results. This application does not limit the calling module.

[0113] It should be noted that the control instructions mainly include but are not limited to initialization, reading files, running programs, saving calculation results, etc.; after initialization, the power equipment model file and the parameter file are read through a specific storage path, and the power equipment model file and the parameter file are written into the calculation library of the simulation software, and then the calculation program of the simulation software is called, and after the simulation calculation is completed, the simulation calculation result file is saved to the specific path, wherein the specific path is also the storage path of the parameter variable in step S1.

[0114] In this way, by calling the power flow calculation program, transient calculation program or short circuit calculation program in the simulation software, the power equipment model file and the parameter file can be quickly simulated and calculated, thereby improving the calculation efficiency.

[0115] The output module 04 is used to parse the simulation calculation result file to obtain a target result file in a unified format.

[0116] Specifically, the output module 04 includes: a second acquisition unit, an extraction unit, a second mapping unit and a second obtaining unit; the second acquisition unit is used to obtain the target output file format corresponding to the data file; the extraction unit is used to extract the simulation calculation result file based on the target output file format to obtain output variables; the second mapping unit is used to establish a second mapping relationship between the simulation calculation result file, the target output file format and the output variables, and encapsulate the second mapping relationship into a second program module; the second obtaining unit is used to obtain a target result file in a unified format based on the second program module.

[0117] It can be understood that after completing the simulation calculation through the simulation software, the simulation calculation result file can be parsed. Specifically, first, the target output file format corresponding to the data file is obtained; secondly, the simulation calculation result file is extracted based on the target output file format to obtain the output variable; thirdly, a second mapping relationship is established between the simulation calculation result file, the target output file format and the output variable, and the second mapping relationship is encapsulated into a second program module; finally, based on the second program module, a target result file in a unified format is obtained. Of course, a mapping relationship can also be established in advance between the simulation calculation result file, the target output file format and the output variable, and encapsulated into several program modules. When the simulation calculation result file is confirmed, the corresponding program module can be directly called to generate a target result file in a unified format.

[0118] It should be noted that when the data file is converted into the power equipment model variables and the parameter variables, the target output file format is clarified, so the target output file format can be directly obtained through the control instruction.

[0119] It should be noted that the simulation calculation result file can be analyzed through, but not limited to, libraries such as pandas and numpy to analyze the simulation output format of the simulation calculation result file, including the sorting of simulation data of each node, data format and result report, etc., which is conducive to the subsequent establishment of a mapping relationship between the target output format and the simulation output format and output variables.

[0120] It should be noted that the target result file in a unified format may be, but is not limited to, an EXCEL table, document, etc., and this application does not impose any restrictions.

[0121] In this way, by parsing the simulation calculation result files, the simulation calculation result files with the corresponding data format of the simulation software can be converted into target result files in a unified format according to the required format. The data generated by various simulation tools can be converted into a unified format to reduce the complexity of data integration and processing, thereby improving the efficiency of simulation analysis of power equipment.

[0122] The embodiment of the present application can convert different data files into power equipment model variables and parameter variables in a same format by parsing the acquired data files into corresponding power equipment model variables and parameter variables, thereby facilitating the subsequent simulation calculations of the simulation software; by respectively converting the power equipment model variables and parameter variables into power equipment model files and parameter files corresponding to the simulation software format, it is convenient to perform simulation calculations on the converted power equipment model files and parameter files, and obtain simulation calculation result files; by parsing the simulation calculation result files, the simulation calculation result files with the corresponding data format of the simulation software can be converted into target result files in a unified format according to the required format, and the data generated by multiple simulation tools can be converted into a unified format to reduce the complexity of data integration and processing, thereby improving the efficiency of power equipment simulation analysis.

It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the scope of protection of the present application.
