[0002] Automatic transfer switch (ATS) is the second line of defense for the stable operation of a power system. Its main function is to quickly and automatically switch to a backup power source after a power outage caused by a grid fault, thereby rapidly restoring power supply and ensuring its continuity. This device plays a crucial role in improving power quality and reliability. To verify the reliable and normal operation of the ATS, regular inspections are necessary.

[0003] Currently, the periodic inspection of automatic transfer switch (ATS) is mainly carried out on-site at the substation.

[0051] This invention provides a method, apparatus, electronic device, and storage medium for automatic backup switching tests, which solves the technical problems of low efficiency and long operation time in existing automatic backup switching test methods.

[0052] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0053] Please see Figure 1 , Figure 1 This is a schematic diagram of a 10kV sectionalized automatic transfer switch primary wiring diagram provided in an embodiment of the present invention. The 10kV sectionalized automatic transfer switch includes a first main transformer (#1 main transformer), a second main transformer (#2 main transformer), a first busbar (10kV 1M), and a second busbar (10kV 2M). The first main transformer is connected to the first busbar via a first main transformer circuit breaker (1DL); the second main transformer is connected to the second busbar via a second main transformer circuit breaker (2DL); the first busbar and the second busbar are connected via a busbar circuit breaker (3DL); 1CT and 2CT are current transformers, and 1PT and 2PT are voltage transformers.

[0054] The inputs for connecting to the 10kV sectional automatic transfer switch include: #1 main transformer low-voltage switch position 1DL (when 1DL=0, the main transformer low-voltage switch is in the open position; when 1DL=1, the #1 main transformer low-voltage switch is in the closed position), #1 main transformer low-voltage switch closed position KKJ1 (when KKJ1=1 and the #1 main transformer low-voltage switch is in the open position, the #1 main transformer low-voltage switch will trip under protection; when KKJ1=0 and the #1 main transformer low-voltage switch is in the open position, the switch will trip manually), #2 main transformer low-voltage switch position 2DL, #2 main transformer low-voltage switch closed position KKJ2, 10kV sectional switch position 1DL, automatic transfer switch function pressure plate, external interlock input, allow 1DL output soft pressure plate, allow 2DL output soft pressure plate, allow 3DL output soft pressure plate, allow 3DL output soft pressure plate, remote test soft pressure plate, etc.

[0055] The analog quantities connected to the 10kV segmented automatic transfer switch are: 10kV 1M three-phase voltage UA1, UB1, UC1; 10kV 2M three-phase voltage UA2, UB2, UC2; #1 main transformer low current IA1, IB1, IC1; #2 main transformer low current IA2, IB2, IC2.

[0056] Please see Figure 2 Based on the 110kV segmented automatic transfer switch in Figure 1, Figure 2 A flowchart of the steps for a self-starting test method is provided.

[0057] This invention provides a backup automatic switching test method, applied to an intelligent substation based on a safe, autonomous, and controllable automation system. The method specifically includes the following steps:

[0058] Step 201: Obtain the operating status of the backup automatic transfer switch;

[0059] In practice, testers can check the operating status of the 10kV section automatic transfer switch under test at the safety substation to determine whether the automatic transfer switch is operating normally and without any abnormal alarm signals. If so, step 202 is executed; otherwise, the process ends and an abnormality is reported for the 10kV section automatic transfer switch test.

[0060] Step 202: When the operating status is determined to be normal operating status, switch the standby automatic transfer to remote test status;

[0061] When the 10kV sectional automatic transfer switch is determined to be in normal operating condition, the test personnel can exit the current operating state of the 10kV sectional automatic transfer switch at the safe substation and switch to the remote test state.

[0062] In one example, when the operating status is determined to be normal, the step of switching the backup automatic transfer switch to the remote test status may specifically include: when the operating status is determined to be normal, deactivating the backup automatic transfer switch's outlet soft pressure plate, activating the backup automatic transfer switch's remote test soft pressure plate, and switching the backup automatic transfer switch to the remote test status.

[0063] In practice, testers can deactivate all the soft pressure plates at the 10kV sectional automatic transfer station outlets at the Anzhi substation; then activate the 10kV sectional automatic transfer remote test soft pressure plate to enter the remote test state.

[0064] The outlet soft pressure plate is used to control whether the actual switch needs to be driven. When the outlet soft pressure plate is retracted, the actual switch cannot be driven. This includes the tripping soft pressure plate, the 2DL tripping soft pressure plate, the 3DL tripping soft pressure plate, and the closing soft pressure plate. Here, "tripping" refers to tripping, and "closing" refers to closing.

[0065] The remote test soft switch is used to control the switching between the 10kV section automatic transfer switch and the remote test state. When the switch is engaged, the 10kV section automatic transfer switch will allow remote testing.

[0066] Step 203: Determine whether the automatic transfer switch is charging based on the first busbar, the second busbar, the first main transformer circuit breaker, the second main transformer circuit breaker, and the busbar circuit breaker.

[0067] After the remote test state of the automatic transfer switch is triggered, the system can determine whether the automatic transfer switch is charging based on the first bus, the second bus, the first main transformer circuit breaker, the second main transformer circuit breaker, and the bus circuit breaker, so as to determine whether to issue a remote test command to the automatic transfer switch.

[0068] In one example, the steps for determining whether the automatic transfer switch (ATS) needs charging based on the first busbar, the second busbar, the first main transformer circuit breaker, the second main transformer circuit breaker, and the busbar circuit breaker include:

[0069] S31, determine whether the standby automatic switching hard plate and soft plate are engaged;

[0070] S32, if yes, determine whether there is voltage on the first busbar and the second busbar;

[0071] S33, if it exists, determine whether the first main transformer circuit breaker and the second main transformer circuit breaker are closed and whether the bus circuit breaker is open.

[0072] S34, If so, determine whether the position after the first main transformer low-voltage switch is closed and the position after the second main transformer low-voltage switch is closed are equal to 1;

[0073] S35, if equal to, determine whether the automatic transfer switch is in an unblocked state;

[0074] S36, if so, determine that the backup automatic transfer switch is in a charging state.

[0075] In specific implementation, the charging conditions for 10kV segmented backup automatic transfer include:

[0076] 1) 10kV sectional automatic transfer switch hard plate is put into operation;

[0077] 2) 10kV segmented automatic transfer switch soft switch activation (including soft switch type 1 and soft switch type 2; when soft switch type 1 is activated, test type 1 can be performed; when soft switch type 2 is activated, test type 2 can be performed).

[0078] 3) The 10kV 1M busbar and 10kV 2M busbar are under voltage;

[0079] 4) 1DL and 2DL combined position, 3DL separated position;

[0080] 5) KKJ1=1, KKJ2=1;

[0081] 6) No interlocking backup automatic transfer switch (the interlocking backup automatic transfer switch will discharge and will no longer be able to operate).

[0082] Step 204: If so, issue a remote test command to the backup system.

[0083] In this embodiment of the invention, the remote test command may include a test command of mode one and a test command of mode two. The test command of mode one includes: setting the second bus voltage to 0 and setting the second bus circuit breaker switch position to 0;

[0084] The test commands for Method 2 include: setting the voltage of the first busbar to 0 and setting the switch position of the first busbar circuit breaker to 0.

[0085] In practice, since the 10kV segmented automatic transfer switch has two main transformers, it is necessary to test the switching function of the two main transformers separately.

[0086] The test commands for the 10kV sectionalized automatic transfer switch mode one include:

[0087] 1) Set the voltages UA2, UB2, and UC2 of the 10kV sectional automatic transfer switch to 0;

[0088] 2) Set the low current IA2, IB2, and IC2 of the #2 main transformer in the 10kV segmented automatic transfer switch to 0;

[0089] 3) Set the position of the #2 main transformer low-voltage 2DL switch of the 10kV segmented automatic transfer switch to 0.

[0090] When the 10kV section automatic transfer switch (ATS) mode 1 test is completed or the system is not in a charging state (mode 1 soft switch not engaged), it can be determined whether mode 2 is in a charging state (mode 2 soft switch engaged). If mode 2 is in a charging state, a mode 2 test command is issued to the ATS. The mode 2 test command includes:

[0091] 1) Set the voltages UA1, UB1, and UC1 of the 10kV sectional automatic transfer switch to 0;

[0092] 2) Set the low current IA1, IB1, and IC1 of the #1 main transformer in the 10kV segmented automatic transfer switch to 0;

[0093] 3) Set the position of the #1 main transformer low 1DL switch of the 10kV segmented automatic transfer switch to 0.

[0094] Step 205: Receive the test results returned by the remote test command for the backup automatic transfer response, and determine whether the backup automatic transfer mode is working properly based on the test results.

[0095] In this embodiment of the invention, after receiving the test results returned by the remote test command for the backup automatic transfer response, it can be determined whether the backup automatic transfer mode is working properly based on the test results.

[0096] In one example, taking the Mode 1 test as an example, the normal test condition is that the automatic substation receives the following message from the 10kV sectional backup automatic transfer station (test result):

[0097] 1) The 10kV sectional standby automatic transfer starts, and the #2 main transformer low-voltage 2DL switch trips after a t1 delay;

[0098] 2) After the 10kV section automatic transfer is detected at the 2DL position, the 10kV section 3DL switch is closed after a delay of t2.

[0099] Taking mode two as an example, the normal test condition is that the Anzhi substation receives the following message from the 10kV sectional backup automatic transfer station (test result):

[0100] 1) The 10kV sectional standby automatic transfer starts, and the #1 main transformer low-voltage 1DL switch trips after a t1 delay;

[0101] 2) After the 10kV section automatic transfer is detected by the 1DL switch, the 10kV section 3DL switch is closed after a delay of t2.

[0102] If the above message is not received, the Anzhi substation will determine that the 10kV section backup automatic transfer test is abnormal.

[0103] This invention acquires the operating status of the automatic transfer switch (ATS). When the operating status is determined to be normal, the ATS is switched to remote testing mode. The system determines whether the ATS is charging based on the first busbar, second busbar, first main transformer circuit breaker, second main transformer circuit breaker, and busbar circuit breaker. If so, a remote testing command is sent to the ATS. The system receives the test results returned by the ATS in response to the remote testing command and determines whether the ATS test is normal based on the test results. This eliminates the need for manual operation, thereby improving testing efficiency and shortening operation time.

[0104] For ease of understanding, the embodiments of the present invention will be described below through specific examples:

[0105] like Figure 3 As shown, Figure 3 This is a flowchart of a 10kV segmented automatic switching test provided in an embodiment of the present invention.

[0106] Step 1: The test personnel check the automatic transfer status of the 10kV section to be tested at the Anzhi substation to see if it is operating normally and without any abnormal alarm signals. If yes, proceed to Step 2; if no, end the process and report an abnormality in the 10kV section automatic transfer test.

[0107] Step 2: The test personnel removed all the soft pressure plates from the 10kV section of the automatic transfer switch at the Anzhi substation;

[0108] The outlet soft pressure plate is used to control whether the actual operation of the switch is required. When the outlet soft pressure plate is removed, the actual operation of the switch is not possible. This includes the tripping soft pressure plate, the tripping soft pressure plate, the tripping soft pressure plate, the closing soft pressure plate, etc. Here, tripping means tripping and closing means closing.

[0109] Step 3: The test personnel put the 10kV segmental automatic transfer remote test soft pressure plate into the Anzhi substation;

[0110] The remote test soft switch is used to control the switching between the 10kV section automatic transfer switch and the remote test state. When the switch is engaged, the 10kV section automatic transfer switch will allow remote testing.

[0111] Step 4: Is the 10kV segmented automatic transfer switch (MTS) mode 1 charged (i.e., is the MTS mode 1 soft switch engaged)? If yes, proceed to step 5; if no, proceed to step 8.

[0112] Step 5: The test personnel issue a remote test command (Method 1) to the 10kV section automatic transfer switch from the Anzhi substation;

[0113] Method 1 remote test command includes: 1) Set the 10kV 2M bus voltages UA2, UB2, and UC2 of the 10kV segmented automatic transfer switch to 0;

[0114] Set the low current IA2, IB2, and IC2 of the #2 main transformer in the 10kV segmented automatic transfer switch to 0;

[0115] Set the position of the #2 main transformer low-voltage 2DL switch of the 10kV segmented automatic transfer switch to 0.

[0116] Step Six: Execute the remote test command for 10kV sectional automatic transfer switch operation in mode one, and feed back the test results to the automatic transfer station.

[0117] Step 7: Determine if the automatic transfer switch test of the 10kV section is normal.

[0118] The normal test condition is that the Anzhi substation receives the following message from the 10kV sectional backup automatic transfer station:

[0119] 1) The 10kV sectional standby automatic transfer starts, and the #2 main transformer low-voltage 2DL switch trips after a t1 delay;

[0120] 2) After the 10kV section automatic transfer is detected at the 2DL position, the 10kV section 3DL switch is closed after a delay of t2.

[0121] Otherwise, the autonomous station will determine that the experiment is abnormal.

[0122] Step 8: Is the 10kV sectional automatic transfer switch mode 2 charging (i.e., is the mode 2 soft switch engaged)? If yes, proceed to step 9; if no, end the process and report an abnormality in the 10kV sectional automatic transfer switch test.

[0123] Step Nine: The test personnel issue a remote test command (Method Two) to the 10kV section automatic transfer switch from the Anzhi substation;

[0124] Method 2 remote test commands include: 1) Setting the 10kV 1M bus voltages UA1, UB1, and UC1 of the 10kV segmented automatic transfer switch to 0;

[0125] Set the low current IA1, IB1, and IC1 of the #1 main transformer in the 10kV segmented automatic transfer switch to 0;

[0126] Set the position of the #1 main transformer low-voltage 1DL switch of the 10kV segmented automatic transfer switch to 0.

[0127] Step 10: Execute the remote test command for the 10kV segmented automatic transfer switch in mode two, and feed back the test results to the automatic transfer station;

[0128] Step 11: Determine if the automatic transfer switch test of the 10kV section is normal.

[0129] The normal test condition is that the Anzhi substation receives the following message from the 10kV sectional backup automatic transfer station:

[0130] 1) The 10kV sectional standby automatic transfer starts, and the #1 main transformer low-voltage 1DL switch trips after a t1 delay;

[0131] 2) After the 10kV section automatic transfer is detected by the 1DL switch, the 10kV section 3DL switch is closed after a delay of t2.

[0132] Otherwise, the autonomous station will determine that the experiment is abnormal.
