[0046] Please see Figure 1One embodiment of the present invention provides a secondary equipment testing method, comprising:

[0047] S1. Based on the standard operating procedure, set the evaluation logic for all test items of the secondary equipment to be tested and the details of the corresponding state sequence for the evaluation logic;

[0048] Please see Figure 2 The secondary equipment testing method provided in this embodiment of the invention is applicable to a secondary equipment testing system, which includes a mobile terminal, a relay protection tester, and a secondary equipment under test. The mobile terminal and the relay protection tester are controlled wirelessly. The relay protection tester outputs a message containing the analog quantities required for the action of the secondary equipment under test, and the message information of the secondary equipment under test is transmitted to the mobile terminal.

[0049] In this embodiment of the invention, the message information is MMS / GOOSE message information.

[0050] Please see Figure 3 This is a schematic diagram of the evaluation logic for the test items provided in an embodiment of the present invention; please refer to... Figure 4 This is a schematic diagram of signal names provided in an embodiment of the present invention.

[0051] S2. Based on the test request, query the state sequence details corresponding to the evaluation logic of the current test item within the preset query range, and record the message information within the preset query range;

[0052] In this embodiment of the invention, the mobile terminal controls the relay protection tester to start increasing the quantity to the secondary device under test, and the mobile terminal starts recording the MMS / GOOSE message information of the device within the preset query range.

[0053] In this embodiment, the increment is a preset voltage and current value in the state sequence details. The devices within the preset query range can be the devices in the current test interval and all devices with virtual connections in the SCD file. Specifically, the virtual connections exist between devices in the SCD due to signal subscription and publication.

[0054] In this embodiment of the invention, after the addition of the quantity is completed, the message information within the preset query range is recorded.

[0055] S3. Traverse each evaluation logic and mark the position of each evaluation logic.

[0056] S4. For the evaluation logic after the displacement mark, group the data according to the state sequence details of the test items to obtain the evaluation logic grouping data; group the message information according to the signal point section to obtain the message information grouping information;

[0057] S5. Compare and evaluate the logical group data and message information group data, and obtain the test results of the secondary device under test based on the comparison results.

[0058] In this embodiment of the invention, the evaluation logic after the displacement mark is grouped according to the state sequence details of the test item to obtain evaluation logic grouping data; the message information is grouped according to the signal point section to obtain message information grouping information; the evaluation logic grouping data and the message information grouping data are compared, and the test results of the secondary device under test are obtained based on the comparison results. By comparing the consistency of the quantity and message parameters of the evaluation logic and message information respectively, the test logic in the test process is increased, thereby effectively avoiding signal omission or signal error during the secondary device test, and thus effectively improving the accuracy and reliability of the secondary device test.

[0059] In one embodiment, before step S2, which queries the state sequence details corresponding to the evaluation logic of the current test item within a preset query range according to the test request, and records the message information within the preset query range, the method further includes:

[0060] S201. Traverse all signal names involved in the evaluation logic to determine the device type and spacing attributes, and establish a standard signal library based on the device type and spacing attributes;

[0061] S202. Based on the standard signal library, parse the SCD file to obtain the original description of the message signal, and automatically associate the original description of the message signal with the standard signals in the standard signal library.

[0062] In this embodiment of the invention, the equipment types can be classified as protection, measurement and control, intelligent terminals, and merging units, etc., and according to the bay attributes, they can be classified as line bays, main transformer bays, busbar bays, bus tie bays, section bays, automatic transfer switch bays, and circuit breaker bays. Please refer to [link / reference]. Figure 5 This is a schematic diagram of a standard signal library provided in an embodiment of the present invention.

[0063] In this embodiment of the invention, the original description of the MMS / GOOSE message is obtained, and the original description is automatically associated with the standard signals in the standard signal library through the correspondence of the original description.

[0064] In one embodiment, S2, recording message information within a preset query range, includes:

[0065] S21. Control the relay protection tester to perform additional processing on the secondary equipment to be tested according to the corresponding state sequence details, and record the message information obtained from the preset range after the additional processing.

[0066] In one embodiment, step S21, recording the message information obtained within a preset range after the increment processing, includes:

[0067] S211. After the incremental processing is completed, set a delay to end the message query and record all message information stored within the preset range.

[0068] In this embodiment of the invention, by setting a delay before ending the message query, the problem of inaccurate test results caused by data transmission delay in practical applications can be effectively solved.

[0069] In one embodiment, step S3, traversing each evaluation logic and marking each evaluation logic by a shift, includes:

[0070] S31. Divide the evaluation logic into action signals and status signals according to signal type;

[0071] Please see Figure 6 In this embodiment of the invention, due to different signal types, the actual evaluation logic will select different shift determination logic according to the order of states and signal types.

[0072] S32. When the action signal is displaced, mark the displacement of the action signal;

[0073] In this embodiment of the invention, the motion signal displacement determination logic is as follows: when there is displacement, that is, when the motion signal state = 1, displacement marking processing is performed to mark the motion signal with displacement.

[0074] S33. Determine whether the current state of the state signal is consistent with the previous state. If they are inconsistent, mark the state signal for change.

[0075] In this embodiment of the invention, the state signal change determination logic is as follows: compare the previous state with the current state. If the two are different, for example, if the previous state of a certain signal is 1 and the current state is 0, it is considered that there is a difference, so a change mark is added.

[0076] The embodiments of the present invention divide the evaluation logic into action signals and status signals according to signal type, and perform displacement marking for different types of signals, which can be applied to a variety of different test items, thereby effectively improving the comprehensiveness and accuracy of secondary equipment testing.

[0077] In one embodiment, step S4 involves grouping the message information according to the signal point sectional area to obtain message information grouping information, including:

[0078] Aspect Rule 1: Use the details of the state sequence as the standard aspect. The number of states in the state sequence determines how many aspects need to be considered in the evaluation logic.

[0079] Section Rule 2: Grouping is performed starting with the grouped feature signal, that is, the signal in the state sequence details of the test item that can indicate the start of the current state.

[0080] In one embodiment, step S5, comparing and evaluating logical packet data and message information packet data, and obtaining the test result of the secondary device under test based on the comparison result, includes:

[0081] S51. Perform a quantity consistency test on the evaluation logic packet data and message information packet data;

[0082] S52. If there is no consistency, the secondary device to be tested is deemed to have failed the test.

[0083] In this embodiment of the invention, all MMS / GOOSE message signals within the test range are grouped according to evaluation logic, i.e., the number of state sequence states = the number of evaluation logic groups = the number of MMS / GOOSE signal groups. If the condition is met, the next evaluation step is performed; otherwise, the secondary device test is directly determined to have failed.

[0084] S53. If they match, compare the message parameters in the message information group data with the message parameters in the preset standard evaluation logic. If they match, the secondary device under test is determined to have been successfully tested. The message parameters include the message order and the message target value.

[0085] In this embodiment of the invention, the message parameters in the message information group data are compared with the message parameters in the preset standard evaluation logic, and the comparison results are visualized, thereby effectively improving the efficiency of secondary equipment test data management.

[0086] In this embodiment of the invention, the comparison rules are as follows:

[0087] Comparison Rule 1: For the determination of action signals, if the signal point does not change in the evaluation logic, the number of signals with the same parameter and a value of 1 in the segmented MMS / GOOSE group is allowed to be 0; if the signal point changes in the evaluation logic, the number of signals with the same parameter and a value of 1 in the segmented MMS / GOOSE group is allowed to be the same.

[0088] Comparison Rule 2: For the determination of state signals, if the signal point does not change in the evaluation logic, the number of identical reference signals allowed in the segmented MMS / GOOSE group is 0; if the signal point changes in the evaluation logic, the number of identical reference signals allowed in the segmented MMS / GOOSE group is consistent.

[0089] Please see Figure 7 This is another flowchart illustrating a secondary equipment testing method provided in an embodiment of the present invention.

[0091] In this embodiment of the invention, the evaluation logic after the displacement mark is grouped according to the state sequence details of the test item to obtain evaluation logic grouping data; the message information is grouped according to the signal point section to obtain message information grouping information; the evaluation logic grouping data and the message information grouping data are compared, and the test results of the secondary device under test are obtained based on the comparison results. By comparing the consistency of the quantity and message parameters of the evaluation logic and message information respectively, the test logic in the test process is increased, thereby effectively avoiding signal omission or signal error during the secondary device test, and thus effectively improving the accuracy and reliability of the secondary device test.

[0092] Furthermore, by classifying the types of evaluation logic, embodiments of the present invention enable compatibility with different test items during secondary equipment testing, thereby effectively improving the comprehensiveness of testing and further enhancing the accuracy and reliability of secondary equipment testing.
