[0003] A simulation distribution simulation model of urban rail transit stray current based on simulation software (for example, CDEGS software) is widely recognized and applied because it can well equivalent line metal structure and line operation environment.

In the embodiment, a computer device is taken as an example for description.

[0068] In an embodiment, the multi-source DC component basic simulation model is constructed, comprising: building a wire model, a substation grounding grid model, a transformer model, a contact net and drainage net model and a DC component excitation source model based on a MALZ module of CDEGS software; constructing a multi-source DC component basic simulation model according to the wire model, the substation grounding grid model, the transformer model, the contact net and drainage net model, the DC component excitation source model and preset parameters; wherein one subway train is equivalent to a group of DC component excitation sources.

[0069] It can be understood that the embodiment takes the simulation distribution of urban rail transit (such as a subway train) stray current based on CDEGS software as an example for description. CDEGS software is a power system design and analysis software, which can be used to quickly and accurately simulate complex electromagnetic field distribution in a power system, grounding system structure and soil characteristics, and communication interference problems of high-voltage transmission lines and substations, etc.

[0070] In an embodiment, when a subway train j is located between two subway stations, n DC component excitation sources are preset, which are a group of DC component excitation sources of the subway train j;

[0071] The positions of the DC component excitation sources are:

[0072] [AD j,1 , AD j,2 ,…, AD j,i ,…, AD j,n ]

[0073] The size of the corresponding excitation source is:

[0074] [I j,1 ,I j,2 ,…,I j,i ,…,I j,n ]

[0075] Among them, AD j,i For the i-th position of the j-th subway train, I j,i Let be the magnitude of the excitation current corresponding to the j-th subway train at the i-th position; 1≤i≤n, 1≤j≤m.

[0076] Specifically, such as Figure 3 Step A, as shown, involves building a multi-source DC component basic simulation model based on the MALZ module of the CDEGS software. This model includes: a conductor model; a substation grounding grid model and a transformer model; a contact network, rail, and drainage network model; and a DC component excitation source model. It should be noted that the position and magnitude of the DC components will change. This embodiment simulates the movement of a rail transit train by changing the position of the DC components. During the simulation, the positions of the shunt component excitation sources are first preset. One subway train is equivalent to a set of DC component excitation sources. When subway train j is located between two subway stations, n DC component excitation sources are preset. These n DC component excitation sources constitute a set of DC component excitation sources for subway train j. The positions of the DC component excitation sources are denoted as:

[0077] [AD j,1 AD j,2 ,…,AD j,i ,…,AD j,n ]

[0078] The size of the corresponding excitation source is:

[0079] [I j,1 ,I j,2 ,…,I j,i ,…,I j,n ]

[0080] Among them, AD j,i For the i-th position of the j-th train, I j,i Let be the magnitude of the excitation current corresponding to the j-th train at the i-th position, 1≤i≤n, 1≤j≤m, for example, Figure 4 This is a schematic diagram of a basic simulation model of a multi-source DC component for a subway example.

[0081] In an embodiment, the batched input file is generated according to the multi-source DC component basis simulation model, including: running the multi-source DC component basis simulation model to generate a basic data input file; batch modifying data in the basic data input file based on a preset programming procedure to obtain the batched input file.

[0082] The batch modifying data in the basic data input file based on the preset programming procedure to obtain the batched input file includes: batch generating excitation current data of time t based on the preset programming procedure and the basic data input file; batch generating excitation current data of the jth subway train based on the preset programming procedure and the basic data input file; determining a train position of the jth subway train according to a train timetable; determining corresponding excitation current according to the train position; determining whether the excitation current setting of all times and all subway trains is completed; and if yes, obtaining the batched input file.

[0083] Specifically, as shown in Figure 3 , the basic data input file is generated according to the multi-source DC component basis simulation model built in step A in step B, and data in the basic data input file is programmed and batch modified to obtain the batched input file.

[0084] Exemplarily, after the multi-source DC component basis simulation model is built, the model is run to automatically generate a file with a suffix.F05, which includes detailed parameters of a conductor model, a substation grounding grid model, a transformer model, a catenary, a rail, a drainage network model, and a DC component excitation source model. In this embodiment, the generated basic data input file mainly includes positions and sizes of excitation sources that need to be modified.

[0085] In an example, as shown in Figure 5 , for time t and the jth subway train, when the train is located at AD j,i , the size of the excitation source corresponding to other positions is set to 0, in addition to I j,i , wherein 1≤i≤n; the size of I j,i is set according to the relationship between the current waveform of the standard subway excitation source and the train position, that is, I j,i =f(AD j,i); determining whether the setting of the excitation current source of all metro trains is completed, if not, setting j = j + 1, and continuing to modify the data of the excitation source of the next metro train; if the excitation current source of all metro trains at time t has been set, a file named "**_t.F05" can be obtained, wherein "**" in the file name represents the name of the project, which can be defined by the user, and t represents the time; determining whether the setting of the excitation current of all metro trains at all times is completed, if not, setting t = t + 1, and continuing to set the excitation current of the metro train at the next time, until the setting of the excitation current of all trains at all times is completed, that is, the batched input file is obtained, which includes the position and size of the excitation source to be modified of all trains at all times. For example, Figure 6 Figure 6 is an example of an input file in the batched input file.

[0086] In an embodiment, based on the automatic simulation process, the batched input file is read, and multi-source DC component simulation is performed according to the batched input file to output simulation results, including: adding the batched input file to the data file sub-process of the automatic simulation process; adding the simulation button in the MALZ module in the CDEGS software to the CDEGS simulation sub-process of the automatic simulation process; setting the simulation interval time based on the simulation interval sub-process of the automatic simulation process; performing multi-source DC component simulation based on the CDEGS simulation sub-process according to the simulation interval time and the batched input file; and outputting the simulation results based on the reading output results sub-process of the automatic simulation process when the batched input file traversal ends.

[0087] Specifically, as shown in Figure 3 , in step C, based on the batched input file obtained in step B, the automatic simulation process is set based on the RPA software to realize automatic reading of the input file and reading of the output results. It should be noted that the automatic simulation process set by the RPA software includes the reading data file sub-process, the CDEGS simulation sub-process, the simulation interval sub-process, and the reading output results sub-process.

[0088] ​Exemplarily, the RPA software is opened, four sub-processes of reading a data file, CDEGS simulation, simulation interval, and reading output results are newly created in the RPA software; the reading data file sub-process is opened, and the path of the batched input file obtained in step B is added to the reading data file sub-process; the CDEGS simulation sub-process is opened, and the simulation button in the MALZ module in the CDEGS software is added to the CDEGS simulation sub-process; the simulation interval sub-process is opened, and the simulation interval time is set, for example, the simulation interval time is set to 10 seconds; the reading output results sub-process is opened, the output module in the MALZ module is added to the reading output results sub-process, and the output results are saved to an Excel file. It can be understood that after all the input files in the path of the batched input file are simulated, the simulation process ends, and the simulation results (for example, an Excel file) of the multi-source DC component automatic simulation are output.

[0089] The embodiment builds a multi-source DC component basic simulation model, generates a batched input file according to the multi-source DC component basic simulation model, sets an automatic simulation process based on RPA software, reads the batched input file based on the automatic simulation process, and performs multi-source DC component simulation according to the batched input file to output simulation results. In the embodiment, the data in the modified basic data input file is batched by programming to obtain a batched input file, and the automatic multi-source DC component simulation is realized by combining the RPA software, so that the problem of complex and large workload of modifying input data when the multi-source DC component simulation is performed by using the CDEGS software can be solved, and the efficiency of the multi-source DC component simulation is improved.

[0090] In addition, the embodiment of the present application also provides a storage medium, and the storage medium stores a multi-source DC component automatic simulation program. When the multi-source DC component automatic simulation program is executed by a processor, the steps of the multi-source DC component automatic simulation method described above are realized.
