Description

Technical Field

[0001] The present application belongs to the field of industrial control digital information, and particularly relates to a method and management system for merging alarms of power distribution equipment. Background Art

[0002] Power distribution equipment is of great significance in the operation of large factories or smart parks, and is the cornerstone for ensuring the normal and orderly operation of factories or parks. In the current power distribution management system, a large number of indicators of power distribution equipment and hundreds of millions of data are often monitored. These indicators and their data are often interrelated in the entire business scenario. If an abnormality occurs, it may trigger a chain of abnormalities, and the management system will issue multiple alarms; or when an abnormality occurs, the management system will repeatedly issue alarms until it is resolved, thus forming a so-called management system alarm storm. For example, a power distribution equipment management system in a smart park once issued hundreds of alarms in one day due to the problem of overvoltage.

[0003] Alarm storms not only slow down operational efficiency and delay troubleshooting, but can also interfere with maintenance personnel, causing them to ignore critical alarms and cause losses. Existing alarm merging methods usually merge alarms one by one based on the alarm association rules manually defined by the manufacturer in advance. This method has many problems such as low scalability and slow analysis speed, and cannot meet the alarm merging requirements of power distribution equipment in industrial scenarios.

[0004] Based on the above situation, using traditional methods to merge the alarms of power distribution equipment in industrial production scenarios does not fit the actual situation of industrial scenarios. There is an urgent need for better and more targeted methods to merge the alarms of power distribution equipment. Summary of the invention

[0005] The embodiment of the present application provides a method and management system for merging alarms of distribution equipment. It uses a pre-constructed alarm relationship matrix to query all parent alarms of the current alarm, and merges the alarms according to the relationship with the occurrence time of the new alarm. Since the method has a fast parent alarm query process and clear and simple merging logic, it greatly improves the processing efficiency and speed of alarm merging and can meet the requirements of the distribution management system for alarm merging.

[0006] In a first aspect, an embodiment of the present application provides a method for merging alarms of a power distribution device, which is used in a power distribution device management system. The method includes:

[0007] An alarm relationship matrix is ​​constructed according to the causal relationship between the alarm types of the power distribution equipment, wherein the elements in the alarm relationship matrix use different values ​​to represent whether there is a causal relationship between the row alarm type where the element is located and the column alarm type;

[0008] When a new alarm occurs in the power distribution equipment management system, the alarm relationship matrix is ​​queried according to the alarm type of the new alarm, wherein all alarm types that can trigger the new alarm are parent alarm types of the new alarm;

[0009] Check whether the parent alarm type exists in the unhandled alarm message in the power distribution equipment management system:

[0010] If it exists, the parent alarm type is selected for alarm merging according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. After the alarm is merged, the alarm notification of the new alarm is absorbed by the parent alarm type, and the power distribution equipment management system does not issue an alarm notification of the new alarm;

[0011] If not, the power distribution equipment management system issues an alarm notification of the new alarm.

[0012] Furthermore, the alarm occurrence time according to the parent alarm type includes:

[0013] If there is only one latest occurring parent alarm type, then the latest occurring parent alarm type is selected as the selected parent alarm type;

[0014] If there are multiple latest parent alarm types that occur simultaneously, a parent alarm type among the latest parent alarm types is randomly selected as the selected parent alarm type.

[0015] Further, selecting the parent alarm type for alarm merging according to the relationship between the occurrence time of the parent alarm and the occurrence time of the new alarm includes:

[0016] Preset alarm merging time interval;

[0017] Before merging the new alarm with the selected parent alarm type, it is necessary to determine the relationship between the time difference between the alarm of the parent alarm type and the new alarm and the alarm merging time interval:

[0018] If the time difference is within the alarm merging time interval, the alarm merging continues to be performed; if the time difference exceeds the alarm merging time interval, the alarm merging is not performed.

[0019] Furthermore, the alarm merging time interval is set according to the application scenario of the power distribution equipment management system and / or the alarm processing level requirement.

[0020] Furthermore, the order of the alarm relationship matrix is ​​equal to the number of alarm types; in the alarm relationship matrix, 0 represents that there is no causal relationship between the alarm types in the row and column where the element is located; in the alarm relationship matrix, 1 represents that the alarm type in the row where the element is located will trigger the alarm type in the column where it is located, and at this time, the alarm type in the row where the element is located is the parent alarm of the alarm type in the column; in the alarm relationship matrix, the initial value of the elements on the diagonal is set to 1, indicating that each alarm type is the parent alarm of its own alarm type.

[0021] Furthermore, after the alarm merging is completed, the new alarm will not issue a separate alarm notification, but the alarm information will be retained in the record of the merged alarm as a basis for evidence retention and subsequent alarm merging queries.

[0022] Furthermore, after the alarm merging is completed, the new alarm will not be counted in the total number of alarms of the power distribution equipment management system.

[0023] In a second aspect, an embodiment of the present application provides a power distribution equipment management system, the system comprising:

[0024] Alarm relationship matrix construction module: construct an alarm relationship matrix according to the causal relationship between the alarm types of the power distribution equipment, and the elements in the alarm relationship matrix use different values ​​to represent the row alarm type where the element is located and whether there is a causal relationship between the column alarm type;

[0025] Alarm type query module: when a new alarm occurs in the power distribution equipment management system, the alarm relationship matrix is ​​queried according to the alarm type of the new alarm, wherein all alarm types that can trigger the new alarm are parent alarm types of the new alarm;

[0026] An unhandled alarm message query module is used to query whether the unhandled alarm message in the power distribution equipment management system contains the parent alarm type;

[0027] Alarm merging analysis execution module: according to the query result of the unprocessed alarm message query module, perform the following operations:

[0028] If it exists, the parent alarm type is selected for alarm merging according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. After the alarm is merged, the alarm notification of the new alarm is absorbed by the parent alarm type, and the power distribution equipment management system does not issue an alarm notification of the new alarm;

[0029] If not, the power distribution equipment management system issues an alarm notification of the new alarm.

[0030] In a third aspect, an embodiment of the present application provides a target device, characterized in that the target device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the computer program, it implements the distribution equipment alarm merging method as described in any one of the first aspects above.

[0031] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the method for merging alarms of distribution equipment as described in any one of the above-mentioned first aspects is implemented.

[0032] It can be understood that the beneficial effects of the second to fourth aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here.

[0033] Compared with the prior art, the embodiments of the present application have the following beneficial effects: in the alarm merging scenario of the power distribution equipment in the industrial scenario, the alarm merging method of the present application quickly executes the alarm merging through the designed alarm relationship matrix when an alarm occurs in the power distribution equipment management system, and the efficiency of the alarm merging is high. The construction or maintenance personnel of the alarm relationship matrix of the present application only need to simply use different numbers to represent whether there is a causal relationship between the row and column where the matrix element is located, so that the construction and maintenance of the alarm relationship matrix can be completed. Therefore, the construction and maintenance of the alarm relationship matrix are very simple. In the present application, the construction or maintenance personnel of the alarm relationship matrix no longer need to have a comprehensive understanding of the entire alarm system like the construction or maintenance personnel of the previous alarm merging system, and fully evaluate the operating mechanism and alarm logic of the overall system to establish a complete alarm merging system, but only need to follow the existing alarm relationship matrix prompts, focus on whether there is a causal relationship between specific alarm services, and then a relatively comprehensive merged alarm system can be established, thereby reducing the training cost of system construction and maintenance personnel, and is very conducive to the expansion and upgrading of the relationship system after adding new controlled equipment. On the other hand, the method of directly randomly selecting the parent alarm type to be merged from the only latest parent alarm type, or directly randomly selecting the parent alarm type to be merged from multiple latest parent alarm types that occur simultaneously, does not need to compare the current alarm time with the occurrence time of each parent alarm one by one. Compared with the existing method of traversing the merging rules one by one, while ensuring the accuracy and effect of the merger, it also greatly improves the speed of retrieval and calculation. In addition, due to the complete decoupling of the selection logic of the alarm to be merged and the alarm relationship matrix construction method, the system can be seamlessly upgraded when the controlled equipment increases. In addition, by presetting the alarm merging interval, the interference of the failed parent alarm can be efficiently filtered, making the alarm merging more accurate. And the alarm merging time interval is set according to the application scenario and / or the alarm processing level requirements, which further improves the accuracy of the alarm merging and can reduce the probability of the occurrence of the wrong merger. Finally, in order to facilitate subsequent queries on alarm mergers, after the merger is completed, the alarm information will remain in the record of the merged alarm, but will not be included in the total alarm statistics of the distribution equipment management system, which not only ensures the traceability and maintainability of the system alarm information, but also ensures the accuracy of the system statistical analysis results.

[0047] The embodiment of the present application provides a method and management system for merging alarms of power distribution equipment. The method uses a pre-constructed alarm relationship matrix to query all parent alarms of the current alarm, and merges the alarms according to the relationship with the occurrence time of the new alarm. The method has a simple alarm relationship matrix construction, which reduces the training cost of system construction and maintainers. The selection logic for the parent alarm to be merged is simple and efficient, which can greatly improve the speed of retrieval and calculation while ensuring the accuracy and effect of the merger. At the same time, in terms of the processing of alarm information, it not only ensures the traceability and maintainability of the system alarm information, but also ensures the accuracy of the system statistical analysis results.

[0048] In one example, the power distribution equipment alarm merging method of the present application is used in a power distribution equipment management system, such as Figure 1 As shown, it includes the following main steps:

[0049] S101, constructing an alarm relationship matrix according to the causal relationship between the alarm types of the power distribution equipment, wherein the elements in the alarm relationship matrix use different values ​​to represent the row alarm type where the element is located, and whether there is a causal relationship between the column alarm type;

[0050] S102: When a new alarm occurs in the power distribution equipment management system, query the alarm relationship matrix according to the alarm type of the new alarm, wherein all alarm types that can trigger the new alarm are parent alarm types of the new alarm;

[0051] S103, querying whether the unhandled alarm message in the power distribution equipment management system contains the parent alarm type:

[0052] If it exists, the parent alarm type is selected for alarm merging according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. After the alarm is merged, the alarm notification of the new alarm is absorbed by the parent alarm type, and the power distribution equipment management system does not issue an alarm notification of the new alarm;

[0053] If not, the power distribution equipment management system issues an alarm notification of the new alarm.

[0054] In order to avoid the occurrence of alarm storms, the current power distribution equipment management system adopts a variety of merging methods, but the control logic, system maintenance and construction process are usually complicated, and the operation is complicated when the management system is upgraded when new power distribution equipment is added, which is not suitable for the requirements of the power distribution management system for the growing modern power distribution facilities. The main steps of the power distribution equipment alarm merging method of the present application are described below in conjunction with the embodiments to illustrate the alarm merging of the present invention.

[0055] S101. Construct an alarm relationship matrix according to the causal relationship between the alarm types of the power distribution equipment. The elements in the alarm relationship matrix use different values ​​to represent the row alarm type where the element is located and whether there is a causal relationship between the column alarm type:

[0056] First, it is necessary to investigate the workflow and business logic in the actual power distribution system, and have a deeper understanding of the collaborative relationship between each work link in the entire scenario; then, organize the alarm type list of the power distribution equipment management system corresponding to the power distribution system, and organize the association relationship of each alarm type on the list with the actual production logic and working mechanism as the guide, and sort out which related alarms may be triggered when a certain alarm occurs. For example, in the power distribution equipment of a factory, when the current has an overcurrent problem, it may also cause a series of problems, such as line overload, circuit tripping, equipment abnormality, etc. Of course, different problems may also cause the same problem, such as circuit tripping problems, whether it is current overcurrent or voltage overvoltage; the association relationship between the above-mentioned various alarms will be stored in the data platform in a matrix for subsequent alarm merging. In one embodiment, taking a factory power distribution system scenario as an example, the business logic of the scenario is first studied, and the alarm type list in the scenario data platform is obtained. As shown in Figure 2, there are 22 types of alarms in this implementation.

[0057] Then, guided by the working mechanism and business logic of the actual operation of the scenario, the alarm relationship is sorted out. For example, when an overvoltage alarm occurs, it is very likely to trigger a local power grid imbalance alarm and an equipment damage alarm. When an undervoltage alarm occurs, it will also cause a local power grid imbalance alarm and an equipment damage alarm. The relationship between these four alarms is sorted out as shown in the alarm matrix B in Figure 3.

[0058] Finally, the 22 alarms in the alarm list are sorted out in sequence according to the above working mechanism, and the global relationship between the alarms is obtained, and the corresponding matrix is ​​sorted out. In the matrix, not only the correlation between various alarms can be reflected, but also whether the alarm will repeat itself. The specific construction process is as follows:

[0059] like Figure 3 As shown, in the embodiment, the order of the alarm relationship matrix B is equal to the number of alarm types, which is 4. In constructing the alarm relationship matrix, 0 represents that there is no causal relationship between the alarm types of the row and column where the element is located; in the alarm relationship matrix, 1 represents that the alarm type of the row where the element is located will trigger the alarm type of the column where it is located. At this time, the alarm type of the row where the element is located is the parent alarm of the alarm type of the column where it is located. Similarly, using the above example to illustrate, for example, when a voltage overvoltage alarm occurs, it is very likely to trigger a local power grid imbalance alarm or an equipment damage alarm. That is to say, in this scenario, the voltage overvoltage alarm is the parent alarm of the local power grid imbalance alarm and the equipment damage alarm. Therefore, in the alarm matrix B, among all the matrix elements in the row where the voltage overvoltage alarm of row 1 is located, the two elements B12 and B13 are both 1, which represents the alarm association relationship between the alarm type B-002 local power grid imbalance alarm in the second column and the alarm type B-003 equipment damage alarm in the third column, which are caused by the voltage overvoltage alarm of B-001; and the alarm type B004 voltage undervoltage alarm in the column where the B14 element is located has no causal relationship with the voltage overvoltage alarm of B-001, so the value of the B14 element is 0. It can be noted that in the alarm relationship matrix, the initial value of the diagonal element, i.e., the causal relationship between the alarm type and itself, is set to 1, which means that each alarm type is the parent alarm of its own alarm type.

[0060] In another embodiment, when a new distribution device is added to the distribution system or a new alarm type is added simply due to new business needs, only one column and one row need to be added to the original alarm relationship matrix to represent the new alarm type, and values ​​are assigned to the elements of the newly added rows and columns according to the above-mentioned matrix element value filling process. After the assignment is completed, the new alarm relationship matrix is ​​constructed, and the subsequent alarm merging process only needs to expand the matrix retrieval range to the new matrix in the original system accordingly, and the overall alarm merging system upgrade can be completed without modifying the judgment logic, merging process, etc., so the equipment expansion effect is good.

[0061] S102: When a new alarm occurs in the power distribution equipment management system, the alarm relationship matrix is ​​queried according to the alarm type of the new alarm, wherein all alarm types that can trigger the new alarm are parent alarm types of the new alarm:

[0062] From the alarm matrix construction logic of step S101, it can be known that among all the column elements of each alarm type in the alarm matrix, the row elements where the elements with a value of 1 are located are all the parent alarms of the alarm type in the column. Figure 4 As shown, the current alarm is the B-003-equipment damage alarm. By searching the alarm matrix B, it can be found that in the third column where the B-003-equipment damage alarm is located, the values ​​of B13, B33, and B43 are 1, which means that in addition to the B-003-equipment damage alarm itself, the alarms B001-voltage overvoltage alarm and B004-voltage undervoltage alarm can cause the B-003-equipment damage alarm to occur, that is, the alarms B001-voltage overvoltage alarm, B004-voltage undervoltage alarm, and B-003-equipment damage alarm itself are all parent alarms of the B-003-equipment damage alarm. These three alarms can cause the B-003-equipment damage alarm to occur.

[0063] S103, query whether the parent alarm type exists in the unprocessed alarm message in the power distribution equipment management system: if it exists, the alarm is merged according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. After the alarm is merged, the alarm notification of the new alarm is absorbed by the parent alarm type, and the power distribution equipment management system does not issue an alarm notification of the new alarm; if it does not exist, the power distribution equipment management system issues an alarm notification of the new alarm:

[0064] like Figure 4 As shown, in the embodiment, after completing step S102, all parent alarms that cause the current alarm B-003-equipment damage alarm are queried through the alarm matrix, and whether these parent alarm types exist in the unprocessed alarm messages in the power distribution equipment management system. In this embodiment, there are multiple unprocessed alarms in the current unprocessed alarm queue in the power distribution equipment management system, among which B001-voltage overvoltage alarm and B004-voltage undervoltage alarm are both parent alarms of B-003-equipment damage alarm, so the two alarms are objects to be merged with B-003-equipment damage alarm.

[0065] In an embodiment, from the above-mentioned multiple parent alarm objects to be merged, alarms are merged according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. Specifically: according to the alarm occurrence time of the parent alarm type, including: if there is a unique latest parent alarm type, then the latest parent alarm type is selected as the selected parent alarm type; if there are multiple latest parent alarm types that occur simultaneously, one of the latest parent alarm types is randomly selected as the selected parent alarm type.

[0066] In this embodiment, if Figure 4 As shown, B001-voltage overvoltage alarm and B004-voltage undervoltage alarm are both parent alarms of B-003-equipment damage alarm, and both exist in the current unprocessed alarm queue in the power distribution equipment management system. Among them, the occurrence time of B001-voltage overvoltage alarm is 15:00 on September 20, 2024, and the occurrence time of B004-voltage undervoltage alarm is 15:30 on September 20, 2024. Compared with the two, since B004-voltage undervoltage alarm is the latest alarm, B004-voltage undervoltage alarm is the final object of this alarm merging selection. The alarm notification of this new alarm is most likely to be absorbed by B004-voltage undervoltage alarm, and the alarm notification of the new alarm will no longer be issued separately.

[0067] In an embodiment, after completing the above-mentioned parent alarm type selection, before merging the new alarm with the selected parent alarm type, it is necessary to judge the relationship between the time difference between the alarm of the parent alarm type and the new alarm and the alarm merging time interval: if the time difference is within the alarm merging time interval, then continue to execute the alarm merging; if the time difference exceeds the alarm merging time interval, then do not perform the alarm merging. The alarm merging time interval is set according to the application scenario of the power distribution equipment management system and / or the alarm processing level requirements.

[0068] In this embodiment, the alarm merging time interval is set to 20 minutes according to the application scenario of the power distribution equipment management system and / or the requirements of the alarm processing level. As shown in Figure 4, the occurrence time of the B-003-equipment damage alarm is 15:40 on September 20, 2024, and the time difference with the selected B004-voltage undervoltage alarm is 10 minutes, which is less than the set alarm merging time interval of 20 minutes. Therefore, it is confirmed to be merged into the B004-voltage undervoltage alarm. After the merger, the B-003 alarm will not generate a new alarm notification.

[0069] In another embodiment, the alarm merging time interval is set to 5 minutes according to the application scenario of the power distribution equipment management system and / or the requirements of the alarm processing level. The occurrence time of the B-003-equipment damage alarm is 15:40 on September 20, 2024, and the time difference between the occurrence time of the selected B004-voltage undervoltage alarm is 10 minutes, which is greater than the set alarm merging time interval of 5 minutes. Therefore, the alarm merging is not performed, and the power distribution equipment management system issues an alarm notification of the new alarm B-003-equipment damage alarm.

[0070] In another embodiment, B001-voltage overvoltage alarm and B004-voltage undervoltage alarm are both parent alarms of B-003-equipment damage alarm, and both exist in the current unprocessed alarm queue in the power distribution equipment management system. Among them, the occurrence time of B001-voltage overvoltage alarm and B004-voltage undervoltage alarm is 15:00 on September 20, 2024, that is, there are multiple latest parent alarm types that occur at the same time. At this time, the system randomly selects any parent alarm type of B001-voltage overvoltage alarm and B004-voltage undervoltage alarm as the final object of this alarm merging selection.

[0071] In another embodiment, after completing step S102 and querying all parent alarms that cause the current alarm B-003-equipment damage alarm through the alarm matrix, it is queried that the parent alarm type of the new alarm B-003-equipment damage alarm does not exist in the unhandled alarm messages in the power distribution equipment management system - any one of B001-voltage overvoltage alarm, B-003-equipment damage alarm and B004-voltage undervoltage alarm. At this time, the power distribution equipment management system issues an alarm notification of the new alarm B-003-equipment damage alarm.

[0072] In another embodiment, after the alarm merging is completed, the new alarm will not send out an alarm notification separately, but the alarm information will be retained in the record of the merged alarm as evidence retention and query basis for subsequent alarm merging.

[0073] In another embodiment, after the alarm merging is completed, the new alarm will not be counted in the total number of alarms of the power distribution equipment management system, so as to avoid distortion of statistical results caused by alarm storms when performing alarm statistics.

[0074] In another embodiment, after the alarm merging is completed, the number of alarms in the current power distribution equipment management system will not increase, but the alarm will exist as a child node under the merged alarm. If the next alarm is triggered by it, it can be merged under it according to the merging rules.

[0075] Based on the same technical concept, such as Figure 5 As shown, the embodiment of the present application also provides a power distribution equipment management system. For the sake of convenience, only the parts related to the embodiment of the present application are shown. Figure 5 The system comprises an alarm relationship matrix construction module 301, an alarm type query module 302, an unhandled alarm message query module 303, and an alarm merging analysis execution module 304.

[0076] Alarm relationship matrix construction module 301: construct an alarm relationship matrix according to the causal relationship between the alarm types of the power distribution equipment, where the elements in the alarm relationship matrix use different values ​​to represent the row alarm type where the element is located and whether there is a causal relationship between the column alarm type;

[0077] Alarm type query module 302: when a new alarm occurs in the power distribution equipment management system, query the alarm relationship matrix according to the alarm type of the new alarm, wherein all alarm types that can trigger the new alarm are parent alarm types of the new alarm;

[0078] Unhandled alarm message query module 303: query whether the parent alarm type exists in the unhandled alarm message in the power distribution equipment management system;

[0079] The alarm merging analysis execution module 304 performs the following operations according to the query result of the unprocessed alarm message query module:

[0080] If it exists, the parent alarm type is selected for alarm merging according to the alarm occurrence time of the parent alarm type and the relationship between the parent alarm occurrence time and the new alarm occurrence time. After the alarm is merged, the alarm notification of the new alarm is absorbed by the parent alarm type, and the power distribution equipment management system does not issue an alarm notification of the new alarm;

[0081] If not, the power distribution equipment management system issues an alarm notification of the new alarm.
