[0076] The low-voltage branch information can be understood as the branch information corresponding to the low-voltage branch bay. Optionally, the low-voltage branch information can comprise the branch number of each low-voltage branch bay and the branch quantity of the low-voltage branch bay.

[0079] In the embodiment of the present application, the virtual loop checking logic can be different in the case that the branch number and the branch quantity corresponding to different main transformers are different. In summary, the present application determines the virtual loop checking logic based on the branch number and the branch quantity, and performs personalized checking on virtual loops of different structures, thereby ensuring the accuracy of virtual loop checking.

[0080] The technical solution of the embodiment of the present application determines the main transformer quantity of the main transformer in the target substation based on the main transformer interval; in the case that the main transformer quantity is one, directly performs virtual loop checking on the target substation based on the actual checking data and the standard checking data corresponding to each target device; in the case that the main transformer quantity is at least two, determines low-voltage branch information based on the low-voltage branch interval, and performs virtual loop checking on the target substation based on the low-voltage branch information, the actual checking data and the standard checking data.

[0081] Figure 5 is a whole flowchart of a virtual loop checking method according to the embodiment one of the present application. As shown in Figure 5 , the whole flowchart of the virtual loop checking method can be:

[0082] 1. Import the SCD file of the target substation, read the IEDNAME (IED device naming, named in eight-bit standard format) of each IED device, parse the IED type, belonging device type, voltage level, belonging device number and IED number information of each IED device according to the rules in the following table, and classify the IED devices of the same device type, voltage level and device number together (hereinafter referred to as classification interval). Classify and divide the protection, intelligent terminal and other IED devices belonging to the same line, transformer, bus and other intervals into an interval.

[0083] 2. The main transformer bay is subdivided into the high, medium, and low voltage sides of the main transformer and the main transformer body. Information from the IEDNAME of all protection devices and intelligent terminals within the main transformer bay is extracted. The side of the main transformer bay to which an intelligent terminal belongs is identified by voltage level, equipment number, and IED number. When there are branches on the low-voltage side of the main transformer, for intelligent terminals on these branches, the equipment description of the IED device is identified. Then, based on the IED description, the intelligent terminals are subdivided into branches one and two on the low-voltage side of the main transformer. Intelligent terminals belonging to the same low-voltage side branch are grouped under one branch. For example, if the intelligent terminals on the low-voltage side branches are all described as #1 main transformer intelligent terminals, they are assigned to the #1 main transformer low-voltage side. The branch is determined by the second-to-last digit of the IEDNAME standard 8-digit naming format; the smaller digit is branch one, and the larger digit is branch two. If there are no branches on the low-voltage side of the main transformer, it is identified as a single branch. The same method is used for cases where the high-voltage side of the main transformer has branches.

[0084] 3. Based on the virtual loop connection relationship between IED devices, the wiring method of the primary system main wiring is determined according to certain rules, including double busbar wiring, double busbar single-section wiring, double busbar double-section wiring, single busbar wiring, single busbar section wiring, and three-half wiring. The low-voltage side of the main transformer generally adopts a single busbar wiring method. For cases where the low-voltage side has branches, it can be further subdivided into single busbar section wiring, single busbar two-section wiring, single busbar three-section wiring, and single busbar five-section wiring. Correspondingly, in single busbar section wiring, the two busbars are named Bus 1 and Bus 2; in single busbar two-section wiring, the busbars are named Bus 1, Bus 2, and Bus 3; in single busbar three-section wiring, the busbars are named Bus 1, Bus 2, Bus 3 (or Bus 5), and Bus 4 (or Bus 6); in single busbar five-section wiring, the busbars are named Bus 1, Bus 2, Bus 3 (or Bus 5), Bus 4 (or Bus 6), Bus 5 (or Bus 8), and Bus 6 (or Bus 9).

[0085] 4. Determine the number and branch number of the low-voltage side branches of the main transformer through step two. Based on the virtual loop connection between the main transformer protection and the intelligent terminal of the low-voltage side branches of the main transformer, extract the association relationship between the low-voltage side branches of the main transformer and the busbars connected to the low-voltage side branches of the primary system.

[0086] 5. Determine the number of main transformer branches, low-voltage side sections, and the relationship between the busbars connected to the low-voltage side sections. This is determined according to the rules for the number of main transformers configured in the SCD, without considering cases with more than 3 main transformers.

[0087] If there is only one main transformer and there are no branches on the low-voltage side, then it does not need to be considered; if there are two branches, the standard virtual terminal template and the standard virtual circuit template can be used for verification.

[0088] If there are two main transformers, the main transformers can be named #1 and #2, or #2 and #3. The corresponding relationships are as follows:

[0089] 1) #1 main transformer without branch, #2 main transformer without branch, low-voltage side bus is 1 bus, 2 bus, and the sectional correlation bus is 1 bus and 2 bus;

[0090] 2) #1 main transformer without branch, #2 main transformer with 2 branches, low-voltage side bus is 1 bus, 2 bus, 3 bus, and the sectional correlation bus is 1 bus and 2 bus;

[0091] 3) #2 main transformer with 2 branches, #3 main transformer without branch, low-voltage side bus is 1 bus, 2 bus, 5 bus, and the sectional correlation bus is 2 bus and 5 bus;

[0092] 4) #1 main transformer with 2 branches, #2 main transformer with 2 branches, low-voltage side bus is 1 bus, 2 bus, 5 bus, 6 bus, and the sectional correlation bus is 2 bus and 5 bus.

[0093] When there are three main transformers, the main transformer naming can be #1, #2, #3 main transformer, or #2, #3, #4 main transformer, and there are the following several cases for specific division:

[0094] 1) #1 transformer without branch, #2 transformer without branch, #3 transformer without branch: low-voltage side bus is 1 bus+2 bus+3 bus, and the sectional correlation bus is 1 bus+2 bus;

[0095] 2) #1 transformer with 1 branch+#2 transformer with 2 branches+#3 transformer with 1 branch: low-voltage side bus is 1 bus+2 bus, 3 bus+5 bus, sectional 1 correlation bus is 1 bus+2 bus, and sectional 2 correlation bus is 3 bus+5 bus;

[0096] 3) #2 transformer with 2 branches+#3 transformer with 1 branch+#4 transformer with 1 branch: low-voltage side bus is 2 bus, 3 bus+5 bus+6 bus, sectional 1 correlation bus is 3 bus+5 bus, and sectional 2 correlation bus is 5 bus+6 bus;

[0097] 4) #1 transformer with 2 branches+#2 transformer with 2 branches+#3 transformer with 2 branches: low-voltage side bus is 1 bus, 2 bus+5 bus, 6 bus+8 bus, 9 bus, sectional 1 correlation bus is 2 bus+5 bus, sectional 2 correlation bus is 6 bus+8 bus, and sectional 3 correlation bus is 1 bus+9 bus.

[0098] 6. Import standard virtual terminal template library and standard virtual circuit template library, and check the virtual circuits of the line, bus and conventional main transformer interval.

[0099] 7. Set the checking mode of the low-voltage side branch of the main transformer to be checked according to the correlation relationship, and check the virtual circuits of the main transformer protection jump section according to the following logic:

[0100] 1. When there is only one main transformer, if there are two branches on the low side, then the main transformer protection jump low-voltage 1 branch section and the jump low-voltage 2 branch section are virtually connected with the section protection, and no interval error is judged, and the correctness of the connection is judged by the principle of virtual circuit connection template.

[0101] 2. When there are two main transformers:

[0102] 2.1 When both main transformers are single-branch, then the main transformer protection jumps low-voltage 1-branch section with virtual connection;

[0103] 2.2 When there are 2-branch and single-branch among the two main transformers, judge whether the main transformer A with smaller serial number is single-branch, if yes, then x in the low-voltage x-branch section jumped by the two main transformers is 1; if not, then x in the low-voltage x-branch section jumped by the main transformer A with smaller serial number is 2, and x in the low-voltage x-branch section jumped by the main transformer with larger serial number is 1;

[0104] 2.3 When both main transformers have two branches, then x in the low-voltage x-branch section jumped by the main transformer with smaller serial number is 2, and x in the low-voltage x-branch section jumped by the main transformer with larger serial number is 1.

[0105] 3. When there are three main transformers (the serial number relationship of A, B, and C is: A < B < C):
