Description

Technical Field

[0001] This application relates to the field of power technology, and in particular to a method, apparatus, device and storage medium for determining abnormal switch displacement. Background Technology

[0002] The position changes of substation switchgear are categorized into three states: open, closed, and intermediate. If the open or closed position change is triggered by unplanned operation, it is considered an abnormal position change. While abnormal position changes of switchgear account for a relatively small percentage of substation operation monitoring, they pose a significant risk. Failure to detect abnormal position changes can severely jeopardize substation operation.

[0003] The existing method mainly adopts manual monitoring and verification, in which staff check the position changes of the switch equipment one by one according to the planned operation steps, and record and report any abnormal changes in the switch equipment.

[0004] However, existing methods are prone to omissions when manually verifying changes in the position of switchgear, resulting in a large workload, low verification efficiency, and low accuracy in identifying abnormal switch position changes. Summary of the Invention

[0033] If the first device information in the first switch operation is consistent with the second device information in the first switch change signal, and the first time information in the first switch operation is inconsistent with the second time information in the first switch change signal, then it is determined that the current switch change signal is abnormal.

[0048] Thirdly, embodiments of this application provide an electronic device, including: a memory and a processor;

Each first switch operation is a switch operation preceding the second switch operation corresponding to the switchgear to be processed in the mapping list. Finally, based on the historical signal acquisition order of the first switch position change signals and the switch operation order of the first switch operations, the information between all first switch operations and all first switch position change signals is compared to determine whether there is an abnormality in the current switch position change signal. In the above method, by acquiring the current switch change signal and at least one first switch change signal preceding the current switch change signal of the switchgear to be processed in the substation, the position change of the switchgear to be processed can be monitored, providing a basis for subsequent judgment. By setting a mapping list, the switching operations that need to be executed according to the plan during the operation of the substation can be accurately reflected. By comparing the current switch change signal with all the switching operations set according to the planned execution order in the mapping list, it can be determined whether the current switch change signal has a corresponding planned switching operation, realizing a preliminary abnormal judgment of the current switch change signal. Furthermore, by comparing the information between the switching operations preceding the second switching operation corresponding to the switchgear to be processed and all the first switch change signals preceding the current switch change signal, it can be finally determined whether the current switch change signal is abnormal, which can effectively improve the accuracy of determining abnormal switch changes.

[0061] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0062] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0063] Before introducing the embodiments of this application, the application background of the embodiments of this application will be explained first:

[0064] The position changes of substation switchgear are categorized into three types: open, closed, and intermediate state. An open change occurs when the switch position changes from closed or an intermediate state to open; a closed change occurs when the switch position changes from open or an intermediate state to closed; and an intermediate state is a state between closed and open. Intermediate states are short-lived and will always revert to either open or closed. If the open or closed position change is triggered by unplanned operation, it is considered an abnormal position change.

[0065] In the monitoring of substation operation, abnormal displacement of switchgear accounts for a small percentage, but it poses a significant threat. Failure to detect abnormal displacement of switchgear can seriously harm the operation of the substation. Current methods mainly rely on manual monitoring and verification, checking the position changes of switchgear one by one according to the planned operating procedures.

[0066] However, existing methods are prone to omissions when manually verifying changes in the position of switchgear, resulting in a large workload, low verification efficiency, and low accuracy in identifying abnormal switch position changes.

[0067] The method for determining abnormal switch position changes provided in this application aims to solve the aforementioned technical problems of the prior art. The inventive concept of this application is as follows: Existing methods rely on manual verification to determine whether a change in the position of a switchgear is a planned operation, resulting in low accuracy in anomaly identification. Determining abnormal switch position changes primarily involves determining whether the change in position corresponds to a planned operation. If multiple verifications can be performed based on equipment and time information in the switch position change signal, the accuracy of determining anomalies in the switch position change can be improved. Therefore, this application first obtains the current switch position change signal of the switchgear to be processed in the substation, and based on the current switch position change signal and a mapping list, determines at least one first switch operation. Each first switch operation is a switch operation preceding the second switch operation corresponding to the switchgear to be processed in the mapping list. By following the sequentially recorded switch operations that conform to planned operations in the mapping list, it can be preliminarily determined whether the current switch position change signal is triggered by a planned operation. Then, the information between the at least one first switch position change signal preceding the current switch position change signal and the at least one first switch operation is compared to determine whether the current switch position change signal is abnormal, thus achieving accurate identification of abnormal switch position signal conditions.

[0068] The execution subject of this application embodiment is an electronic device, which can be a terminal device, such as a laptop, desktop computer, or tablet computer, or a server. In practical applications, whether the electronic device is a terminal device or a server can be determined according to the actual situation, and no specific limitation is imposed on it.

[0069] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0070] Figure 1 A flowchart illustrating the abnormal determination method for switch displacement provided in this application embodiment. Figure 1 .like Figure 1 As shown, the method for determining the abnormality of the switch displacement includes the following steps:

[0071] S110. Obtain the current switch change signal and at least one first switch change signal preceding the current switch change signal of the switchgear to be processed in the substation.

[0072] The current switch change signal includes: the current device information and the corresponding current time information of the switch device to be processed; the first switch change signal includes: the first device information and the first time information of the switch device to be processed; and at least one first switch change signal is arranged in the order of historical signal acquisition.

[0073] In this step, the current switch change signal of the switchgear to be processed in the substation and at least one first switch change signal arranged in the order of historical signal acquisition before the current switch change signal are obtained. The current switch change signal carries the current equipment information and the corresponding current time information of the switchgear to be processed, and the first switch change signal carries the first equipment information and the first time information of the switchgear to be processed, providing a basis for subsequent analysis of whether there is any abnormality in the current switch change signal.

[0074] For example, the equipment information corresponding to the switchgear to be processed includes the name of the switchgear to be processed and the position change type of the switchgear to be processed, i.e., closing type or opening type; the time information is used to indicate the sending time or generation time of the switch change signal.

[0075] In one possible implementation, the substation includes an operation monitoring system and a measurement and control device. This application embodiment applies to the operation monitoring system in the substation. The measurement and control device collects the current switch change signal of the switchgear to be processed in the substation and sends the current switch change signal to the operation monitoring system. The operation monitoring system acquires the current change signal and performs subsequent analysis. At least one first switch change signal preceding the current switch change signal is stored in the operation monitoring system and can be retrieved from it.

[0076] S120. Based on the current switch change signal and the mapping list, determine at least one first switch operation. Each first switch operation is a switch operation preceding the second switch operation corresponding to the switch device to be processed in the mapping list.

[0077] The mapping list includes at least one switching operation arranged in the order of switching operations, and each switching operation includes device information and time information.

[0078] In this step, the mapping list records at least one switch operation arranged in the order of switch operation. Each switch operation includes: device information and time information. Based on the device information and time information of the switch device to be processed carried by the current switch change signal, the second switch operation corresponding to the switch device to be processed is determined in the mapping list. Then, the switch operations before the second switch operation in the mapping list are determined as at least one first switch operation.

[0079] For example, the second switching operation refers to a switching operation in which the device information and time information are the same as the device information and time information of the switching device to be processed corresponding to the current switching change signal.

[0080] In one possible implementation, the mapping list can be one or more. If the current switch signal does not identify the second switch operation corresponding to the switch device to be processed in the current mapping list, the matching continues in other mapping lists until all mapping lists have been traversed.

[0081] In one possible implementation, prior to step S120 above, the method for determining the abnormality of the switch displacement further includes the following steps:

[0082] Step 1: Obtain the operation ticket information for the switchgear to be processed;

[0083] The operation ticket information includes at least one operation step arranged in the order of switch operation.

[0084] For example, the operation ticket information includes at least one operation step arranged in the order of switch operation, and each operation step is associated with the corresponding equipment operation of the equipment in the substation.

[0085] In one possible implementation, at least one operation step in the operation ticket information is recorded in the planned operation sequence. There may be substation equipment associated with an operation step that is other than switchgear, in which case the operation step can be ignored.

[0086] Extract the operation steps associated with the switching equipment in the substation from each operation step in the operation ticket information, and arrange them according to the switching operation sequence to obtain at least one operation step arranged according to the switching operation sequence.

[0087] Step 2: Determine the mapping list based on at least one switch operation in each operation step.

[0088] For example, each operation step includes at least one switching operation, and the operation ticket information of the switching device to be processed is converted into a mapping list based on the at least one switching operation.

[0089] In one possible implementation, at least one switching operation in each operation step includes the name of the switching device, the type of switching operation, the command execution time, and the repeat command completion time.

[0090] The device name and operation type of each switching operation are respectively used as the device name and operation type in the device information corresponding to the switching operation recorded in the mapping list. The command execution time and repeat command completion time of each operation are respectively used as the operation start time and operation end time corresponding to the switching operation recorded in the mapping list.

[0091] For example, if operation step 1 in the operation ticket information corresponds to only one switch operation 1, then the first switch operation recorded in the mapping list corresponds to switch operation 1; the command execution time 1 and the re-completion time 1 of operation step 1 are respectively used as the operation start time 1 and operation end time 1 of the switch operation 1 recorded in the mapping list.

[0092] If operation step 2 in the operation ticket information corresponds to switch operation 2 and switch operation 3, then the second and third switch operations recorded in the mapping list correspond to switch operation 2 and switch operation 3, respectively. The order execution time 2 of operation step 2 is used as the operation start time 2 and operation start time 3 of switch operation 3 recorded in the mapping list. The repeat order completion time 2 of operation step 2 is used as the operation end time 2 and operation end time 3 of switch operation 2 and switch operation 3 recorded in the mapping list. That is, the operation start time and operation end time of switch operation 2 and switch operation 3 are the same.

[0093] Table 1 is an example of a mapping list. As shown in Table 1, the mapping list includes the operation steps, switch operation (including switch device name and switch operation type), operation start time, and operation end time in the operation ticket information.

[0094] Table 1:

[0095]

[0096] S130. Based on the historical signal acquisition sequence of the first switch change signal and the switching operation sequence of the first switch operation, compare whether the information between all first switch operations and all first switch change signals is consistent, so as to determine whether there is an abnormality in the current switch change signal.

[0097] In this step, according to the historical signal acquisition order of the first switch change signal and the switching operation order of the first switch operation, the device information and time information between all first switch operations and all first switch change signals are compared to determine whether there is an anomaly in the current switch change signal.

[0098] In one possible implementation, when the comparison result shows that the device information and timing information between all first switch operations and all first switch change signals are consistent, it indicates that all first switch change signals are triggered by the first switch operations in the corresponding mapping list, and the mapping list is recorded according to the planned operation sequence.

[0099] In one possible implementation, if the second switch operation corresponding to the switchgear to be processed is not determined, then it is determined that there is an anomaly in the current switch position signal.

[0100] For example, before step S120 above, it is necessary to first determine the second switch operation corresponding to the switch device to be processed in the mapping list.

[0101] The mapping list can be one or more. If the second switch operation corresponding to the switch device to be processed cannot be determined after traversing all the mapping lists, then it is directly determined that there is an abnormality in the current switch position signal.

[0102] The method for determining anomalies in switch position changes provided in this application first acquires the current switch position change signal of the switchgear to be processed in the substation and at least one first switch position change signal preceding the current switch position change signal. Then, based on the current switch position change signal and a mapping list, at least one first switch operation is determined. Each first switch operation is a switch operation preceding the second switch operation corresponding to the switchgear to be processed in the mapping list. Finally, based on the historical signal acquisition order of the first switch position change signal and the switch operation order of the first switch operation, the information between all first switch operations and all first switch position change signals is compared to determine whether there is an anomaly in the current switch position change signal. In this embodiment, by acquiring the current switch change signal and at least one first switch change signal preceding the current switch change signal of the switchgear to be processed in the substation, the position change of the switchgear to be processed can be monitored, providing a basis for subsequent judgment. By setting a mapping list, the switching operations that need to be executed according to the plan during the operation of the substation can be accurately reflected. By comparing the current switch change signal with all the switching operations set according to the planned execution order in the mapping list, it can be determined whether the current switch change signal has a corresponding planned switching operation, realizing a preliminary abnormal judgment of the current switch change signal. Furthermore, by comparing the information between the switching operations preceding the second switching operation corresponding to the switchgear to be processed and all the first switch change signals preceding the current switch change signal, it can be finally determined whether the current switch change signal is abnormal, which can effectively improve the accuracy of determining abnormal switch changes.

[0103] Based on the above embodiments, Figure 2 A flowchart illustrating the abnormal determination method for switch displacement provided in this application embodiment. Figure 2 .like Figure 2 As shown, a possible implementation of step S130 above also includes the following steps:

[0104] S210. For each historical signal acquisition sequence that is the same as the switching operation sequence of the first switch operation, if the first device information in the first switch operation is inconsistent with the second device information in the first switch change signal, then it is determined that the current switch change signal is abnormal.

[0105] In this step, for each first switch change signal whose historical signal acquisition sequence is the same as the switch operation sequence of the first switch operation, the first device information in the first switch operation is compared with the second device information in the first switch change signal. If the first device information and the second device information are inconsistent, it is determined that there is an anomaly in the current switch change signal.

[0106] For example, the device information includes the name of the switchgear and the type of switchgear.

[0107] In one possible implementation, if the switch device name in the first device information is different from the switch device name in the second device information, it directly indicates that the first device information and the second device information are inconsistent.

[0108] For example, the first device information is: switch A is closed, and the second device information is: switch B is closed.

[0109] If the switch device name in the first device information is the same as the switch device name in the second device information, but the switch device type in the first device information is different from the switch device type in the second device information, it can also be said that the first device information and the second device information are inconsistent.

[0110] For example, the first device information is: switch A is closed, and the second device information is: switch A is open.

[0111] S220. If the first device information in the first switch operation is consistent with the second device information in the first switch change signal, and the first time information in the first switch operation is inconsistent with the second time information in the first switch change signal, then it is determined that there is an abnormality in the current switch change signal.

[0112] In this step, when the first device information in the first switch operation is consistent with the second device information in the first switch change signal, the first time information in the first switch operation is compared with the second time information in the first switch change signal. If they are inconsistent, it is determined that there is an abnormality in the current switch change signal.

[0113] For example, the first time information includes the operation start time and operation end time, and the second time information includes the command execution time and the repeat command completion time.

[0114] In one possible implementation, if the command execution time is before the operation start time, it indicates that the first time information and the second time information are inconsistent, and it can be directly determined that the current switch change signal is abnormal.

[0115] If the command execution time is after the operation start time and the re-completion time is after the operation end time, it can also indicate that the first time information and the second time information are inconsistent, and it can be determined that the current switch change signal is abnormal.

[0116] If the command execution time is after the operation start time and the re-completion time is before the operation end time, it means that the first time information and the second time information are consistent, and it can be determined that the current switch change signal is normal.

[0117] The method for determining the anomaly of switch change provided in this application firstly targets each first switch change signal whose historical signal acquisition order is the same as the switch operation order of the first switch operation. If the first device information in the first switch operation is inconsistent with the second device information in the first switch change signal, then it is determined that the current switch change signal is abnormal. Then, if the first device information in the first switch operation is consistent with the second device information in the first switch change signal, and the first time information in the first switch operation is inconsistent with the second time information in the first switch change signal, then it is determined that the current switch change signal is abnormal. In this embodiment, for each first switch change signal with the same first switch operation and sequence, the system determines whether there is an anomaly in the current switch change signal by checking whether the information between the first switch operation and the first switch change signal is consistent. A comprehensive comparison is performed sequentially to determine whether the current switch change signal accurately reflects the planned operation of the switching equipment. By comparing equipment information and time information, dual verification can effectively improve the accuracy of identifying abnormal switch changes. Automatic comparison of equipment information and time information according to a set procedure can reduce manual intervention, improve overall operational efficiency, prevent omissions or misjudgments during manual verification, and thus improve the operating efficiency and safety of the substation.

[0118] Based on the above embodiments, Figure 3 A flowchart illustrating the abnormal determination method for switch displacement provided in this application embodiment. Figure 3 .like Figure 3 As shown, a possible implementation of step S120 above also includes the following steps:

[0119] S310. Based on the first device information and first time information in the current switch change signal, as well as the mapping list, determine the second switch operation corresponding to the switch device to be processed.

[0120] In this step, the first device information and the first time information in the current switch signal are compared with the device information and time information included in each switch operation in the mapping list. The switch operation whose first device information is consistent with the device information in the mapping list and whose first time information is consistent with the time information in the mapping list is determined as the second switch operation corresponding to the switch device to be processed.

[0121] In one possible implementation, firstly, a switching operation that matches the first device information in the current switch change signal is determined in the mapping list. For example, the device information is: switch device B is open. Then, among the switching operations that match the first device information in the current switch change signal, the switching operation whose time information matches the time information in the current switch change signal is determined. This is the second switching operation corresponding to the switch device to be processed.

[0122] The second switching operation corresponding to the switchgear to be processed can be a switching operation whose command execution time of the current switch change signal is after the start time of the operation of the switch operation and whose reorder completion time is before the end time of the operation of the current switch change signal; if the time information of the current switch change signal only includes the command execution time, then the second switching operation corresponding to the switchgear to be processed can be a switching operation whose command execution time of the current switch change signal is after the start time of the operation of the switch operation.

[0123] S320. Determine at least one first switch operation prior to the second switch operation in the mapping list.

[0124] In this step, the second switch operation is identified from the mapping list, and then at least one first switch operation arranged in sequence prior to the second switch operation is identified.

[0125] For example, at least one first switch operation is arranged in an operation sequence that conforms to the planned operation sequence of the substation.

[0126] In one possible implementation, the mapping list can be one or more. If a second switch operation is determined in the current mapping list, then all switch operations preceding the second switch operation in the current operation list are determined as at least one first switch operation.

[0127] The method for determining abnormal switch position changes provided in this application first determines the second switch operation corresponding to the switch device to be processed based on the first device information and first time information in the current switch position change signal, as well as a mapping list. Then, at least one first switch operation preceding the second switch operation is determined from the mapping list. In this embodiment, by determining a second switch operation in the mapping list that is identical to the first device information and first time information in the current position change signal, the mapping list is effectively utilized to confirm the consistency between the switch operation and the switch position change signal, ensuring that the current position change signal is triggered by the second switch operation. By determining at least one first switch operation preceding the second switch operation in the mapping list, planned switch operations preceding the second switch operation corresponding to the current position change signal can be indicated, providing a basis for subsequently confirming the correctness of the corresponding sequence of the current position change signal. By comparing the overall sequence, the accuracy of determining abnormal switch position changes can be effectively improved.

[0128] Based on the above embodiments, Figure 4 A flowchart illustrating the abnormal determination method for switch displacement provided in this application embodiment. Figure 4 .like Figure 4 As shown, the corresponding equipment information includes: equipment name and operation type; correspondingly, the method for determining the abnormality of this switch position change also includes the following steps:

[0129] S410. If there is an abnormality in the current switch change signal, then obtain the number of all switch change signals of the switch device to be processed within a preset time period according to the device name in the first device information.

[0130] In this step, if there is an abnormality in the current switch position change signal, the number of all switch position change signals corresponding to the switch device to be processed corresponding to the device name in the first device information is obtained within a preset time period.

[0131] For example, the preset duration is set to any integer number of minutes between 5 and 15 minutes.

[0132] In one possible implementation, if the preset duration is 15 minutes, then within 15 minutes before the command execution time corresponding to the current switch change signal, the number of all switch change signals of the switch device to be processed, including the device name in the first device information, is obtained.

[0133] For example, if the device name in the first device information of the current switch change signal is switch device D, then within 15 minutes before the command execution time corresponding to the current switch change signal, obtain the number of all switch change signals corresponding to switch device D.

[0134] S420. If the number of all switch position change signals is equal to the preset number, and the operation type corresponding to at least one switch position change signal is inconsistent with the operation type in the equipment information, then the switch equipment to be processed is determined to be abnormal.

[0135] In this step, if the number of at least one switch position change signal is equal to the preset number, the operation type corresponding to at least one switch position change signal is further compared with the operation type in the device information. If they are inconsistent, the switch device to be processed is determined to be in an abnormal position change.

[0136] For example, the preset number is set to 3, and the operation type includes intermediate state, which is the intermediate state between closing operation and opening operation.

[0137] In one possible implementation, when the operation type corresponding to at least one switch position change signal is an intermediate state, it can be directly regarded as the operation type being consistent with the operation type in the device information.

[0138] If the number of at least three switch position change signals is equal, then the three operation types corresponding to these three switch position change signals are determined and compared with the operation type in the device information of the current switch position change signal.

[0139] For example, if the operation type in the device information of the current switch signal is a tripping operation, and the three operation types corresponding to the three switch position change signals are tripping operation, intermediate state, and tripping operation, it means that the switch device to be processed corresponding to the current switch signal has a brief monitoring abnormality, which is normal, and the position change of the switch device to be processed is normal.

[0140] If the operation type in the device information of the current switch signal is closing operation, and the three operation types corresponding to the three switch position change signals are closing operation, intermediate state, and closing operation, this is normal, and the position change of the switch device to be processed is normal.

[0141] In one possible implementation, if the number of at least one switch displacement signal is greater than or less than a preset number, it indicates that the switch device to be processed is in an abnormal displacement state.

[0142] In one possible implementation, if there is no abnormality in the current switch position signal, a verification completion tag is added to the second switch operation.

[0143] For example, if there is no abnormality in the current switch position change signal, a verification completion tag is added to the second switch operation in the mapping list. When the switch position change signal is subsequently determined to be abnormal, it will no longer be matched and verified with the second operation.

[0144] The method for determining abnormal switch displacement provided in this application firstly identifies an abnormal switch displacement signal. Based on the device name in the first device information, the number of all switch displacement signals for the switch to be processed within a preset time period is obtained. Then, if the number of all switch displacement signals equals the preset number, and at least one of the switch displacement signals corresponds to an operation type inconsistent with the operation type in the device information, the switch to be processed is determined to be in an abnormal displacement state. In this embodiment, if the current switch displacement signal is abnormal, the method further determines whether the switch to be processed corresponding to the current switch displacement signal is abnormal, effectively improving the accuracy of abnormal displacement identification. By obtaining the number of displacement signals for the switch to be processed within a preset time period, it can be determined whether the switch to be processed has moved normally. If the operation type is inconsistent with the operation type in the device information, it indicates that the switch to be processed may have a fault or abnormal operation. This determination improves the accuracy of abnormal detection and reduces false alarms.

[0152] If the first device information in the first switch operation is consistent with the second device information in the first switch change signal, and the first time information in the first switch operation is inconsistent with the second time information in the first switch change signal, then it is determined that there is an abnormality in the current switch change signal.
