[0053] See also Figure 1 , Figure 1 A schematic diagram of a 10kV segmented standby automatic switching primary wiring diagram provided in an embodiment of the present invention. The 10kV segmented standby automatic switching includes a first main transformer (#1 main transformer), a second main transformer (#2 main transformer), a first busbar (10kV 1M), a second busbar (10kV 2M), the first main transformer is connected to the first busbar through a first main transformer circuit breaker (1DL); the second main transformer is connected to the second busbar through a second main transformer circuit breaker (2DL); the first busbar and the second busbar are connected through a busbar circuit breaker (3DL); 1CT and 2CT are current transformers, and 1PT and 2PT are voltage transformers.

[0056] See also Figure 2 , based on the 110kV section backup automatic switch in Figure 1, Figure 2 A flow chart of the steps of a self-test method is provided.

[0057] The invention provides a standby automatic test method, which is applied to a safe autonomous substation. The safe autonomous substation is an intelligent substation based on a safe, autonomous and controllable automation system, and can specifically include the following steps:

[0058] Step 201, obtaining the operation status of the standby automatic start-up;

[0059] In the specific implementation, the test personnel can check the operating status of the 10kV segmented standby automatic transfer to be tested at the safety station to determine whether the standby automatic transfer is operating normally and there is no abnormal alarm signal. If so, execute step 202; if not, end the process and report the 10kV segmented standby automatic transfer test abnormality.

[0060] Step 202, when it is determined that the operation state is the normal operation state, the standby automatic switching is switched to the remote test state;

[0061] When it is determined that the 10kV section standby automatic switching is in normal operating state, the test personnel can exit the current operating state of the 10kV section standby automatic switching at the safety station and switch to the remote test state.

[0062] In one example, when the operating state is determined to be a normal operating state, the step of switching the standby automatic start-up to a remote test state may specifically include: when the operating state is determined to be a normal operating state, exiting the standby automatic start-up exit soft pressure plate, engaging the standby automatic start-up remote test soft pressure plate, and switching the standby automatic start-up to a remote test state.

[0063] In the specific implementation, the test personnel can exit all the export soft pressure plates of the 10kV section standby automatic transfer at the automatic station; then put in the 10kV section standby automatic transfer remote test soft pressure plate to enter the remote test state.

[0064] Among them, the exit soft pressure plate is used to control whether the actual transmission switch is required. When the exit soft pressure plate is withdrawn, the actual transmission switch cannot be transmitted, including the 1DL soft pressure plate for allowing cutting, the 2DL soft pressure plate for allowing cutting, the 3DL soft pressure plate for allowing cutting, and the 3DL soft pressure plate for allowing closing. Among them, the "allowing cutting" refers to tripping, and the "allowing closing" refers to closing.

[0065] The remote test soft pressure plate is used to control the switching of the 10kV section standby automatic switching between operation and remote test status. When the pressure plate is put into operation, the 10kV section standby automatic switching will allow remote testing.

[0066] Step 203, judging whether the standby automatic switch is charged according to the first bus, the second bus, the first main transformer circuit breaker, the second main transformer circuit breaker and the bus circuit breaker;

[0067] After triggering the remote test state of the standby automatic starter, it can be determined whether the standby automatic starter is charged 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 to determine whether to send a remote test command to the standby automatic starter.

[0068] In one example, the step of determining whether the standby automatic switch is charged according to the first bus, the second bus, the first main transformer circuit breaker, the second main transformer circuit breaker and the bus circuit breaker includes:

[0069] S31, judging whether the hard pressure plate and the soft pressure plate of the automatic start-up are in operation;

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

[0071] S33, if it exists, determine whether the first main transformer circuit breaker and the second main transformer circuit breaker are in the closed position, and whether the busbar circuit breaker is in the open position;

[0072] S34, if yes, determine whether the closing position of the first main transformer low switch and the closing position of the second main transformer low switch are equal to 1;

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

[0074] S36: If yes, determine that the standby automatic switch is in charging state.

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

[0076] 1) 10kV segmented standby automatic switching hard pressure plate is put into use;

[0077] 2) 10kV sectional standby automatic soft pressure plate is put into operation (including mode 1 soft pressure plate and mode 2 soft pressure plate. When mode 1 soft pressure plate is put into operation, mode 1 test can be carried out, and when mode 2 soft pressure plate is put into operation, mode 2 test can be carried out);

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

[0079] 4) 1DL, 2DL combined, 3DL divided;

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

[0081] 6) There is no interlocking automatic start-up (the interlocking automatic start-up will discharge and cannot operate again).

[0082] Step 204, if yes, send a remote test command to the standby automatic drop;

[0083] In the embodiment of the present invention, the remote test command may include a mode 1 test command and a mode 2 test command. The mode 1 test command includes: setting the second bus voltage to 0, setting the second bus circuit breaker switch position to 0;

[0084] The test command of mode 2 includes: setting the voltage of the first busbar to 0, and setting the switch position of the first busbar circuit breaker to 0.

[0085] In the specific implementation, since the 10kV sectioned backup automatic switch has two main transformers, it is necessary to test the switching functions of the two main transformers separately.

[0086] 10kV sectional standby automatic switching mode 1 test command includes:

[0087] 1) Set the 10kV 2M bus voltages UA2, UB2, and UC2 of the 10kV sectional standby automatic switch to 0;

[0088] 2) Set the low currents IA2, IB2 and IC2 of the 10kV sectional standby automatic switching #2 main transformer to 0;

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

[0090] When the 10kV sectional standby automatic switching mode 1 has completed the test or is not in the charging state (mode 1 soft pressure plate is not engaged), it can be determined whether mode 2 is in the charging state (mode 2 soft pressure plate is engaged). If mode 2 is in the charging state, a mode 2 test command is sent to the standby automatic switching. Mode 2 test commands include:

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

[0092] 2) Set the low currents IA1, IB1 and IC1 of the 10kV sectional standby automatic switching #1 main transformer to 0;

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

[0094] Step 205, receiving the test result returned by the standby automatic start-up mode in response to the remote test command, and judging whether the standby automatic start-up mode is tested normally according to the test result.

[0095] In the embodiment of the present invention, after receiving the test result returned by the standby automatic start-up mode in response to the remote test command, it can be determined whether the standby automatic start-up mode is tested normally according to the test result.

[0096] In one example, taking the method 1 test as an example, the judgment condition for the normal test is that the main station receives the following message (test result) of the 10kV section standby automatic transfer:

[0097] 1) 10kV sectional standby automatic start-up, after t1 delay, the #2 main transformer low 2DL switch is tripped;

[0098] 2) After the 10kV section backup automatic switch detects the 2DL position, it closes the 10kV section 3DL switch after a delay of t2.

[0099] Taking method 2 as an example, the judgment condition for the normal test is that the Anzi substation receives the following message (test result) from the 10kV section backup automatic transfer:

[0100] 1) 10kV sectional standby automatic start-up, after t1 delay, the #1 main transformer low 1DL switch is tripped;

[0101] 2) After the 10kV section standby automatic switch detects the 1DL position, it closes the 10kV section 3DL switch after a delay of t2.

[0102] If the above message is not received, the safety control station will determine that the 10kV section standby automatic transfer test is abnormal.

[0103] The present invention obtains the operating status of the standby automatic switch; when the operating status is determined to be a normal operating state, the standby automatic switch is switched to a remote test state; whether the standby automatic switch is charged is determined according to the first bus, the second bus, the first main transformer circuit breaker, the second main transformer circuit breaker and the bus circuit breaker; if so, a remote test command is issued to the standby automatic switch; the test result returned by the standby automatic switch in response to the remote test command is received, and whether the standby automatic switch mode is tested normally is determined according to the test result. No manual operation is required, thereby improving the test efficiency and shortening the operation time.

[0104] For ease of understanding, the embodiments of the present invention are described below by using specific examples:

[0105] like Figure 3 As shown, Figure 3 A flow chart of a 10kV segmented standby automatic switching test provided in an embodiment of the present invention.

[0106] Step 1: The test personnel check the operating status of the 10kV sectional standby automatic switch to be tested at the safety station. Is it running normally and without abnormal alarm signals? If yes, proceed to step 2; if not, end the process and report the abnormality of the 10kV sectional standby automatic switch test;

[0107] Step 2: The test personnel withdraw all the soft pressure plates of the 10kV section standby automatic switch at the automatic station;

[0108] The exit soft pressure plate is used to control whether the actual transmission switch is required. When the exit soft pressure plate is withdrawn, the actual transmission switch cannot be transmitted, including the 1DL soft pressure plate for allowing cutting, the 2DL soft pressure plate for allowing cutting, the 3DL soft pressure plate for allowing cutting, and the 3DL soft pressure plate for allowing closing. Among them, the cutting refers to tripping, and the closing refers to closing.

[0109] Step 3: The test personnel put into operation the 10kV segmented standby automatic remote test soft pressure plate at the automatic station;

[0110] The remote test soft pressure plate is used to control the switching of the 10kV sectional standby automatic switching between the operation and remote test states. When the pressure plate is put into operation, the 10kV sectional standby automatic switching will allow remote testing;

[0111] Step 4: Is the 10kV sectional standby automatic switching mode 1 charged (i.e., is the soft pressure plate in mode 1 switched on)? If yes, proceed to step 5; if no, proceed to step 8;

[0112] Step 5: The test personnel issue a remote test command of mode 1 to the 10kV section standby automatic switch at the automatic station;

[0113] Mode 1 remote test commands include: 1) setting the 10kV 2M bus voltages UA2, UB2, and UC2 of the 10kV sectional standby automatic switch to 0;

[0114] Set the low currents IA2, IB2 and IC2 of the 10kV sectional standby automatic switching #2 main transformer to 0;

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

[0116] Step 6: 10kV sectional standby automatic switching execution mode 1 remote test command, and feedback the test results to the safety station

[0117] Step 7: Install the self-service station to determine whether the 10kV section standby automatic switching test is normal?

[0118] The condition for judging whether the test is normal is that the Anzi substation receives the following message from the 10kV section standby automatic switch:

[0119] 1) 10kV sectional standby automatic start-up, after t1 delay, the #2 main transformer low 2DL switch is tripped;

[0120] 2) After the 10kV section backup automatic switch detects the 2DL position, it closes the 10kV section 3DL switch after a delay of t2.

[0121] Otherwise, the safety station determines that the test is abnormal.

[0122] Step 8: Is the 10kV sectional standby automatic switching mode 2 charged (i.e., is the mode 2 soft pressure plate engaged)? If yes, proceed to step 9. If no, end the process and report the 10kV sectional standby automatic switching test abnormality;

[0123] Step 9: The test personnel issue the mode 2 remote test command to the 10kV section standby automatic switch at the installation station;

[0124] Mode 2 remote test commands include: 1) setting the 10kV 1M bus voltages UA1, UB1, and UC1 of the 10kV sectional standby automatic switch to 0;

[0125] Set the low currents IA1, IB1 and IC1 of the 10kV sectional standby automatic switching #1 main transformer to 0;

[0126] Set the low 1DL switch position of the #1 main transformer of the 10kV sectioned backup automatic switching to 0.

[0127] Step 10: 10kV sectional standby automatic switching executes the remote test command of mode 2, and feeds back the test results to the safety control station;

[0128] Step 11: Install the self-service station to determine whether the 10kV section standby automatic switching test is normal?

[0129] The condition for judging whether the test is normal is that the Anzi substation receives the following message from the 10kV section standby automatic switch:

[0130] 1) 10kV sectional standby automatic start-up, after t1 delay, the #1 main transformer low 1DL switch is tripped;

[0131] 2) After the 10kV section standby automatic switch detects the 1DL position, it closes the 10kV section 3DL switch after a delay of t2.

[0132] Otherwise, the safety station determines that the test is abnormal.
