Description

Technical Field

[0001] The present invention relates to the technical field of intelligent substation data processing, and in particular to a method for automatically generating a virtual terminal table of an intelligent substation. Background Art

[0002] As an important foundation and node support for smart grids, more than 10,000 smart substations have been put into operation across the country. With the basic requirements of digitalization of full-station information, networking of communication platforms, and standardization of information sharing, smart substations automatically complete basic functions such as information collection, measurement, control, protection, metering, and monitoring.

[0003] The application of new technologies and new standards has affected many aspects of smart substation design, engineering implementation, operation and maintenance. Specifically in the design of smart substations, the design products provided by design institutes no longer only include traditional design blueprints and manufacturer's blank drawings. The design of virtual terminal tables in smart substations has become the core of smart substation design. The correctness of the virtual circuit directly affects the realization of the protection function and is crucial to the safe operation of smart substations.

[0004] The application of merging units and intelligent terminals in smart substations realizes the digitization of sampling and tripping signals. The traditional hard-wired circuits of secondary equipment are replaced by invisible and intangible virtual circuits. The hard-wiring design based on terminal blocks in the original conventional substations is transformed into a virtual terminal table design based on virtual terminals in ICD model files.

[0005] Different design units are aware that the workload of virtual terminal table design is large, manual connection of virtual terminals is cumbersome and very error-prone, and there is a large amount of repeated design work and low work efficiency during the design and implementation of new projects or renovation and expansion projects. The advantages of digitalization of smart station information and standardization of information sharing are not fully utilized. The virtual circuit design of smart stations still has great development potential.

[0006] Chinese patent CN103268362A "Virtual terminal auxiliary design method based on universal template and key character matching" discloses a virtual terminal auxiliary design method based on universal template and key character matching. This method uses the similarity of virtual terminal names and definitions of various manufacturers to match key characters of the virtual terminals to be associated with the universal template, and adjusts the order of the virtual terminals to be associated to make them consistent with the positions of virtual terminals with the same functions in the universal template, thereby completing the automatic association of virtual terminals.

[0007] Chinese patent CN107025329A "Method for automatic connection of virtual circuits in smart substations" discloses a method for automatic connection of virtual circuits in smart substations, which inputs typical technical solutions in technical manuals into a computer to generate a tree-like circuit matching model including voltage levels, bays, bay equipment and information flows;

[0008] The above methods are all based on auxiliary design software with ICD model configuration function. Design institutes need to configure special hardware and software tools, and designers are required to be familiar with ICD model file modeling knowledge. In addition, the dedicated auxiliary design software does not have collaborative design function and does not meet the existing collaborative design work mode of the design institute. All of the above limit the promotion and popularization of auxiliary design software with ICD model configuration function. Nowadays, many design institutes are still using traditional EXCEL spreadsheet editors for virtual terminal table design.

[0009] However, the existing traditional EXCEL spreadsheet editor for virtual terminal table design has great drawbacks. In the traditional design method, the IED equipment does not have digital information and does not meet the basic requirements of digitalization of the entire station information and standardization of information sharing; manual configuration is labor-intensive and prone to errors, there is a lot of repetitive work, the design period is long, and the efficiency is low. The collaborative work platform of the design institute has not realized the informatization, automation and intelligence of virtual circuit design. It is urgent to change the virtual circuit design method to make the virtual circuit design more efficient and of better quality. Summary of the invention

[0010] In order to overcome the shortcomings of the prior art, the present invention provides a method for automatically generating a virtual terminal table for an intelligent substation, which realizes changing the design process and method of the virtual terminal table and improves the efficiency of virtual circuit design.

[0011] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0012] The first aspect of the present application provides a method for automatically generating a virtual terminal table of a smart substation, comprising the following steps:

[0013] S101, generating several typical bay IED equipment configuration information tables based on the smart substation data information, and formulating corresponding typical bay virtual terminal table files;

[0014] S102, importing virtual terminal mapping file information corresponding to the ICD model files of several IED devices into the i-th typical interval virtual terminal table file;

[0015] S103, in the i-th typical interval virtual terminal table file, for the k-th virtual terminal on the j-th IED device, based on the virtual terminal mapping file and the standard virtual circuit file corresponding to the ICD model file of the IED device on the local side, generate the opposite side IED device name and the ICD model file mapping virtual terminal of the opposite side IED device corresponding to the row where the k-th virtual terminal on the j-th IED device is located;

[0016] S104, generating an i-th typical bay virtual terminal table based on traversing the ICD model file virtual terminals of all IED devices in the i-th typical bay;

[0017] S105. Generate a virtual terminal table file for the entire smart substation by summarizing all typical interval virtual terminal table files.

[0018] Furthermore, the typical bay IED device configuration information table includes: main transformer bay, line bay, busbar bay, busbar bay, circuit breaker bay... The information table includes the typical bay name and the ICD model file information corresponding to the IED device in the bay.

[0019] Furthermore, when the typical interval is the busbar interval, the correspondence between each branch in the busbar protection and the actual interval is clarified. The branches of each interval of the busbar protection include the busbar coupling branch, section branch, line branch and main transformer branch, and the correspondence between each branch and the actual interval is clarified.

[0020] Further, generating several typical bay IED equipment configuration information tables based on the smart substation data information and formulating corresponding typical bay virtual terminal table files includes the following steps:

[0021] Based on the main wiring diagram, bay division and IED device configuration information in the bay, determine M typical bay IED device configuration information tables;

[0022] Create a virtual terminal table file based on each typical interval.

[0023] Furthermore, formulating a virtual terminal table file based on each typical interval includes the following steps:

[0024] Create a new EXCEL file and set the name to Typical Interval;

[0025] The number of worksheets in the EXCEL file is determined by the typical bay IED device configuration information table. Each IED device corresponds to a virtual terminal table and is named IED device.

[0026] The header contents of the virtual terminal table corresponding to each IED device are the same, and the header contents include serial number, ICD model virtual terminal data attributes, ICD model virtual terminal data description, standard virtual terminal, data type, opposite IED device name, opposite ICD model virtual terminal description and opposite ICD model virtual terminal attributes.

[0027] Further, importing virtual terminal mapping file information corresponding to the ICD model files of several IED devices into the i-th typical interval virtual terminal table file includes the following steps:

[0028] Based on each different ICD model file in the typical bay IED equipment configuration information table, a new EXCEL file is created, and the file name consists of the IED manufacturer name, device model, device version, and check code;

[0029] The header content in the EXCEL file is serial number, ICD model virtual terminal data attribute, ICD model virtual terminal data description, standard virtual terminal, data type;

[0030] The ICD models corresponding to the verification codes of different manufacturers, different device models and versions are mapped to the standard virtual terminals according to the principle of consistent virtual terminal functions, and a virtual terminal mapping file is prepared.

[0031] Furthermore, the CRC of the IED device corresponding to the ICD model file refers to the CRC check code of the IED device software program, which is automatically generated according to a specific CRC check rule and is used to distinguish the uniqueness of the IED device software.

[0032] Further, in the i-th typical interval virtual terminal table file, the k-th virtual terminal on the j-th IED device on the local side, based on the virtual terminal mapping file and the standard virtual circuit file corresponding to the ICD model file of the IED device on the local side, generates the opposite side IED device name corresponding to the row where the k-th virtual terminal on the j-th IED device is located and the ICD model file mapping virtual terminal of the opposite side IED device, including the following steps:

[0033] According to the standard virtual terminal in the virtual terminal mapping file corresponding to the ICD model file of the IED device on this side, the device code and the standard virtual terminal on the opposite side are obtained through the standard virtual circuit file corresponding to the IED device on this side;

[0034] By parsing the opposite IED device code and obtaining the IED device name from the typical interval, the opposite IED device name corresponding to the row where the kth virtual terminal on this side is located in the jth IED device is automatically generated;

[0035] By obtaining the opposite side standard virtual terminal, according to the standard virtual terminal in the ICD virtual terminal mapping file of the opposite side IED device, the ICD model file virtual terminal of the opposite side IED device corresponding to the row where the kth virtual terminal on this side in the jth IED device is located is automatically generated.

[0036] Further, according to the standard virtual terminal in the virtual terminal mapping file corresponding to the ICD model file of the IED device on this side, through the standard virtual circuit file corresponding to the IED device on this side, obtaining the opposite side IED device code and the opposite side standard virtual terminal includes the following steps:

[0037] For each different IED device type in the typical bay IED device configuration information table, a new EXCEL file is created with the file name local IED device code_opposite IED device code;

[0038] The header content in the EXCEL file is the serial number, the IED equipment code on this side, the standard virtual terminal on this side, the data type, the IED equipment code on the opposite side, and the standard virtual terminal on the opposite side;

[0039] The content of the EXCEL file is the maximized set of standard virtual circuits of the IED device type. All standard virtual circuits are determined according to the general design scheme of the smart substation and the virtual terminal table of the smart substation.

[0040] Furthermore, for each different IED device type in the typical bay IED device configuration information table, a new EXCEL file is created correspondingly, and the file name is local IED device code_opposite IED device code, which includes the following steps:

[0041] The IED equipment coding content consists of IED equipment type, equipment object, main wiring type, voltage level, IED equipment set, and switch type;

[0042] Encoding is based on IED device type, belonging device type, voltage level, and set type;

[0043] The main connection types include double bus connection, double bus double branch connection, double bus single branch, single bus connection, 3 / 2 connection, internal bridge connection, expanded internal bridge connection, variable group connection, single bus segmented connection, single bus three segments, single bus four segments, single bus six segments, single bus eight segments, etc. Different main connection types are coded in sequence using a hexadecimal 1 to F;

[0044] The switch types include line-side circuit breakers, main transformer-side circuit breakers, line-to-line complete string circuit breakers, line-to-transformer complete string circuit breakers, line-to-line incomplete string circuit breakers, line-to-transformer incomplete string circuit breakers, etc. The switch types are encoded in sequence using a hexadecimal 1 to F.

[0045] The beneficial effects of the present application are as follows: it realizes the change of the virtual terminal table design process and method, and improves the accuracy and efficiency of the virtual terminal table design. The existing virtual terminal table design process is changed, and the virtual terminal table of the ICD model file originally imported into the IED device is changed to the virtual terminal mapping file of the ICD model file imported into the IED device, and the standard virtual circuit file is used to provide technical support and data support for the automatic generation of virtual circuits. The existing virtual terminal table production method is changed from manually producing the virtual terminal table to automatically generating the virtual terminal table. The virtual terminal mapping files and standard virtual circuit files corresponding to the ICD model files of different IED devices are summarized to form a virtual terminal mapping file library and a standard virtual circuit library, so as to realize the reuse of virtual terminal mapping files and standard virtual circuit files of different IED devices during the implementation of virtual terminal design. In the design of virtual terminals for new construction projects or renovation and expansion projects, the virtual terminal mapping file corresponding to the ICD model file of the corresponding IED device is directly retrieved or replaced in the virtual terminal mapping file library to realize the automatic generation or update of virtual circuits.

[0046] Collaborative design is achieved, which significantly shortens the design period. Virtual terminal design is performed in the EXCEL spreadsheet editor, and designers from different volumes can design virtual terminal tables in parallel, which is in line with the existing collaborative design work mode of design institutes. Different designers simultaneously complete the hard circuit and virtual circuit design of typical intervals in their respective volumes, and then complete the automatic design of virtual circuits between cross-interval equipment. Finally, the virtual terminal tables of each volume are summarized to form a virtual terminal table for the entire site, shortening the construction period and saving costs.

[0054] Embodiment 1:

[0055] A method for automatically generating a virtual terminal table of an intelligent substation comprises the following steps:

[0056] S101, generating several typical bay IED equipment configuration information tables based on the smart substation data information, and formulating corresponding typical bay virtual terminal table files;

[0057] Obtain the data information of the smart substation, generate several typical interval IED device configuration information tables based on the data information of the smart substation, and formulate corresponding typical interval virtual terminal table files. For example, generate M typical interval IED device configuration information tables based on the data information of the smart substation, and formulate corresponding M typical interval virtual terminal table files. The typical interval IED device configuration information table includes: main transformer interval, line interval, busbar interval, busbar interval, circuit breaker interval... The information table includes the typical interval name and the ICD model file information corresponding to the IED device in the interval. Furthermore, when the typical interval is a busbar interval, it is necessary to clarify the correspondence between each branch in the busbar protection and the actual interval. The branches of each interval of the busbar protection include busbar branches, segmented branches, line branches and main transformer branches, and the correspondence between each branch and the actual interval is clarified.

[0058] Generating several typical bay IED equipment configuration information tables based on smart substation data information and formulating corresponding typical bay virtual terminal table files includes the following steps:

[0059] Based on the main wiring diagram, bay division and IED device configuration information in the bay, determine M typical bay IED device configuration information tables;

[0060] Create a virtual terminal table file based on each typical interval.

[0061] The following steps are involved in developing a virtual terminal table file for each typical interval:

[0062] Create a new EXCEL file and set the name to Typical Interval;

[0063] The number of worksheets in the EXCEL file is determined by the typical bay IED device configuration information table. Each IED device corresponds to a virtual terminal table and is named IED device.

[0064] The header contents of the virtual terminal table corresponding to each IED device are the same, and the header contents include serial number, ICD model virtual terminal data attributes, ICD model virtual terminal data description, standard virtual terminal, data type, opposite IED device name, opposite ICD model virtual terminal description and opposite ICD model virtual terminal attributes.

[0065] It should be noted that the IED device configuration information includes the IED device name, ICD model file information and manufacturer name, etc. The IED device name is determined by the IED device configuration information in the design drawing, and the ICD model file information is provided by each device manufacturer, and a virtual terminal information table corresponding to the ICD model file information is also provided.

[0066] For example, the entire smart substation has 7 typical bays, namely 220kV bus bay, 220kV line bay, 220kV bus bay, 110kV bus bay, 110kV line bay, 110kV bus bay and main transformer bay. The IED device configuration information table for the 220kV line typical bay is as follows:

[0067] Table 1 220kV line typical bay IED equipment configuration information table

[0068] Serial number IED device name IED equipment corresponds to ICD model 1 220kV line protection set A WXH-803B_V1.0_BDFA838B.icd 2 220kV line merging unit A set PRS-7393-1F-G-A2_.icd 3 220kV Line Intelligent Terminal Set A PRS-7789-V2.0_3BC0BB8A.icd 4 220kV line protection set B PCS-931A-DA-GR-V4.00-138DA74C.icd 5 220kV line merging unit set B PRS-7393-1F-G-A2_.icd 6 220kV Line Intelligent Terminal Set B PRS-7789-V2.0_3BC0BB8A.icd 7 220kV line measurement and control PRS-7741-T-V2.10-C3BF8410.icd

[0069] According to Table 1, an EXCEL file is prepared for the typical interval of 220kV line. The file name is 220kV line interval virtual terminal table, which includes 7 worksheets. The work names are 220kV line protection set A, 220kV line merging unit set A, 220kV line intelligent terminal set A, 220kV line protection set B, 220kV line merging unit set B, 220kV line intelligent terminal set B and 220kV line measurement and control.

[0070] See the attached diagram for the typical interval virtual terminal header composition diagram. Figure 3 .

[0071] S102, importing virtual terminal mapping file information corresponding to the ICD model files of several IED devices into the i-th typical interval virtual terminal table file;

[0072] By generating several typical bay IED device configuration information tables based on the smart substation data information and formulating corresponding typical bay virtual terminal table files, the virtual terminal mapping file information corresponding to the ICD model files of several IED devices is imported into the i-th typical bay virtual terminal table file.

[0073] Importing virtual terminal mapping file information corresponding to the ICD model files of several IED devices into the i-th typical interval virtual terminal table file includes the following steps:

[0074] Based on each different ICD model file in the typical bay IED equipment configuration information table, a new EXCEL file is created, and the file name consists of the IED manufacturer name, device model, device version, and check code;

[0075] The header content in the EXCEL file is serial number, ICD model virtual terminal data attribute, ICD model virtual terminal data description, standard virtual terminal, data type;

[0076] The ICD models corresponding to the verification codes of different manufacturers, different device models and versions are mapped to the standard virtual terminals according to the principle of consistent virtual terminal functions, and a virtual terminal mapping file is prepared.

[0077] It should be noted that the standard virtual terminals are determined by the promulgated technical regulations and specifications related to smart substations; the standard virtual terminals of measurement and control devices can be determined by the enterprise standards formulated by various design institutes; the data types include GOOSE input, GOOSE output, SV input and SV output.

[0078] Furthermore, the CRC of the IED device corresponding to the ICD model file refers to the CRC check code of the IED device software program, which is automatically generated according to a specific CRC check rule and is used to distinguish the uniqueness of the IED device software.

[0079] For example, according to the 220kV line typical interval IED equipment configuration information table, formulate the virtual terminal mapping file corresponding to the 220kV line intelligent terminal set A and the 220kV line protection set A ICD model file.

[0080] The virtual terminal mapping file corresponding to the 220kV line protection set A ICD model file is named XJDQ_WXH-803B_V1.0_BDFA838B, and the virtual terminal mapping file corresponding to the 220kV line intelligent terminal set A ICD model file is named CYSR_PRS-7393-1F-G-A2_V2.0_3BC0BB8A, as shown in Table 2 and Table 3 respectively.

[0081] Table 2XJDQ_WXH-803B_V1.0_BDFA838B virtual terminal mapping file

[0082]

[0083] Table 3 CYSR_PRS-7393-1F-G-A2_V2.0_3BC0BB8A virtual terminal mapping file

[0084]

[0085] In Tables 2 and 3, the virtual terminal data attributes of the ICD model file, the description of the ICD model virtual terminal data and the data type are shown. The virtual terminal mapping files corresponding to the 220kV line intelligent terminal set A and 220kV line protection set A ICD model files are imported into the 220kV line typical interval virtual terminal table.

[0086] S103, in the i-th typical interval virtual terminal table file, for the k-th virtual terminal on the j-th IED device, based on the virtual terminal mapping file and the standard virtual circuit file corresponding to the ICD model file of the IED device on the local side, generate the opposite side IED device name and the ICD model file mapping virtual terminal of the opposite side IED device corresponding to the row where the k-th virtual terminal on the j-th IED device is located;

[0087] By importing the virtual terminal mapping file information corresponding to the ICD model files of several IED devices into the i-th typical interval virtual terminal table file, and by using the k-th virtual terminal on the local side of the j-th IED device in the i-th typical interval virtual terminal table file, according to the virtual terminal mapping file and the standard virtual circuit file corresponding to the ICD model file of the IED device on the local side, the opposite side IED device name corresponding to the row where the k-th virtual terminal on the local side of the j-th IED device is located and the ICD model file of the opposite side IED device The virtual terminal is automatically generated.

[0088] In the i-th typical interval virtual terminal table file, the k-th virtual terminal on the j-th IED device generates the opposite IED device name and the ICD model file mapping virtual terminal of the opposite IED device corresponding to the row where the k-th virtual terminal on the j-th IED device is located based on the virtual terminal mapping file and the standard virtual circuit file corresponding to the ICD model file of the IED device on the local side, including the following steps:

[0089] According to the standard virtual terminal in the virtual terminal mapping file corresponding to the ICD model file of the IED device on this side, the device code and the standard virtual terminal on the opposite side are obtained through the standard virtual circuit file corresponding to the IED device on this side;

[0090] By parsing the opposite IED device code and obtaining the IED device name from the typical interval, the opposite IED device name corresponding to the row where the kth virtual terminal on this side is located in the jth IED device is automatically generated;

[0091] By obtaining the opposite side standard virtual terminal, according to the standard virtual terminal in the ICD virtual terminal mapping file of the opposite side IED device, the ICD model file virtual terminal of the opposite side IED device corresponding to the row where the kth virtual terminal on this side in the jth IED device is located is automatically generated.

[0092] According to the standard virtual terminal in the virtual terminal mapping file corresponding to the ICD model file of the IED device on this side, obtaining the opposite side IED device code and the opposite side standard virtual terminal through the standard virtual circuit file corresponding to the IED device on this side includes the following steps:

[0093] For each different IED device type in the typical bay IED device configuration information table, a new EXCEL file is created with the file name local IED device code_opposite IED device code;

[0094] The header content in the EXCEL file is the serial number, the IED equipment code on this side, the standard virtual terminal on this side, the data type, the IED equipment code on the opposite side, and the standard virtual terminal on the opposite side;

[0095] The content of the EXCEL file is the maximized set of standard virtual circuits of the IED device type. All standard virtual circuits are determined according to the general design scheme of the smart substation and the virtual terminal table of the smart substation.

[0096] For each different IED device type, a new EXCEL file is created. The file name is IED device code on this side_IED device code on the opposite side. The following steps are included:

[0097] The IED equipment coding content consists of IED equipment type, equipment object, main wiring type, voltage level, IED equipment set, and switch type;

[0098] Encoding is based on IED device type, belonging device type, voltage level, and set type;

[0099] The main connection types include double bus connection, double bus double branch connection, double bus single branch, single bus connection, 3 / 2 connection, internal bridge connection, expanded internal bridge connection, variable group connection, single bus segmented connection, single bus three segments, single bus four segments, single bus six segments, single bus eight segments, etc. Different main connection types are coded in sequence using a hexadecimal 1 to F;

[0100] The switch types include line-side circuit breakers, main transformer-side circuit breakers, line-to-line complete string circuit breakers, line-to-transformer complete string circuit breakers, line-to-line incomplete string circuit breakers, line-to-transformer incomplete string circuit breakers, etc. The switch types are encoded in sequence using a hexadecimal 1 to F.

[0101] It should be noted that the IED device type, belonging device type, voltage level, and set coding rules can be formulated according to Appendix B Table B.1 "IED name table" of DL / T 1873 "Technical Specifications for Smart Substation System Configuration Description (SCD) File".

[0102] Optionally, when the IED device object is a main transformer and the voltage level is 110kV or below, the IED device set coding rules are as follows:

[0103] When the main transformer bay is configured according to the dual main-rear integrated protection, IED device set A represents the first set of main transformer protection, and IED device set B represents the second set of main transformer protection;

[0104] When the main transformer bay is configured with dual sets of main and rear integrated protection, IED equipment set C represents the first set of main transformer protection, and IED equipment set D represents the second set of main transformer protection;

[0105] When the main transformer bay is configured with double protection and backup protection is configured on each side, IED type E represents the main transformer differential protection, IED type F represents the main transformer high backup protection, IED type G represents the main transformer medium backup protection, and IED type H represents the main transformer low backup protection;

[0106] When the IED device code does not need to identify the main wiring type, the main wiring type code is 0;

[0107] When the IED device code does not need to distinguish the voltage level, the voltage level code is 00.

[0108] For example, formulate the standard virtual circuit file of 220kV line intelligent terminal as shown in Table 4:

[0109] Table 4 220kV line intelligent terminal standard virtual circuit file

[0110] Serial number IED device code on this side Standard virtual terminal on this side Data Types Opposite IED device code Opposite side standard virtual terminal 1 I_L_22_1A Protection jump A1 GOOSE reception P_L_22_1A Trip circuit breaker phase A 2 I_L_22_1A Protection jump B1 GOOSE reception P_L_22_1A Trip circuit breaker phase B 3 I_L_22_1A Protection jump C1 GOOSE reception P_L_22_1A Trip circuit breaker phase C 4 I_L_22_1A Lock reclosing 1 GOOSE reception P_L_22_1A Locking reclosing 5 I_L_22_1A Protection reclosing 1 GOOSE reception P_L_22_1A Reclosing 6 I_L_22_1A Protect TJR three jumps 1 GOOSE reception P_M_22_1A Branch 4_Protection trip

[0111] The equipment codes on this side and the opposite side in Table 4 are formulated according to the typical interval information configuration table of 220kV lines and the voltage level and main connection type corresponding to the interval. For example, for the first row of virtual terminal "A phase trip 1" in the virtual terminal table of set A of 220kV line intelligent terminal, the standard virtual terminal "protection trip A1" is found in the virtual terminal mapping file of Table 3. Through the standard virtual circuit file of 220kV line intelligent terminal, the equipment code of the opposite side is obtained as P_L_22_1A. After parsing the equipment code on the opposite side, the IED type of the equipment on the opposite side is protection, the belonging equipment object is line, and the set is set A. In the typical interval virtual terminal table file, the name of the equipment on the opposite side can be determined as 220kV line protection set A.

[0112] Through the standard virtual circuit file of the 220kV line intelligent terminal, according to the standard virtual terminal "Protection Trip A1" corresponding to the 220kV line protection set A, the opposite standard virtual terminal is obtained as "Tripping Circuit Breaker Phase A", and the ICD model virtual terminal description "Protection Action" is found in the virtual terminal mapping file in Table 2. The ICD model virtual terminal data reference is "PIGO / PTRC2.Op.phsA".

[0113] The specific implementation process of step 3 can be seen Figure 4 : Schematic diagram of automatic generation of virtual terminals. The automatic generation effect of the first row of virtual terminals in the virtual terminal table of set A of the 220kV line intelligent terminal is shown in Table 5 below:

[0115]

[0116] S104, generating an i-th typical bay virtual terminal table based on traversing the ICD model file virtual terminals of all IED devices in the i-th typical bay;

[0117] Through the virtual terminal mapping file and standard virtual circuit file corresponding to the ICD model file of the IED device on this side, the Kth virtual terminal on this side of the jth IED device in the i-th typical interval virtual terminal table file is used to generate the opposite side IED device name and the ICD model file mapping virtual terminal of the opposite side IED device corresponding to the row where the kth virtual terminal on this side of the j-th IED device is located. Based on traversing the ICD model file virtual terminals of all IED devices in the i-th typical interval, the i-th typical interval virtual terminal table is generated.
