Description

Technical Field

[0001] The present invention belongs to the technical field of power system dispatching automation, and relates to a technology for improving the monitoring efficiency of power system dispatching automation monitoring personnel, and more specifically, to an intelligent diversion handling method and system for frequent alarms. Background Art

[0002] With the expansion of the scale of the power grid and the growth of user demand, a variety of abnormal phenomena have occurred in the operation of the power grid, resulting in the frequent generation of warning signals, including a large number of invalid or mis-sent signals. Monitoring personnel need to determine the cause and specific location of the fault based on the type of these warning signals, and perform corresponding troubleshooting. However, due to the large number of warning messages and the complexity of the situation, and the fact that some monitoring personnel may lack sufficient experience and processing capabilities, this often leads to an untimely response to the alarm information, thus affecting the normal operation of the power grid.

[0003] In order to ensure the safety and stability of the power system, existing technologies have designed and implemented a set of power grid alarm processing and response systems. The system classifies and manages alarm information in an automated manner, and provides a variety of response methods including voice, sound prompts, SMS notifications, and phone calls to achieve real-time, accurate, and reliable alarm processing effects. Despite this, current technical means are still insufficient for the various types of frequent alarm signal problems that actually exist in the power grid. It is impossible to completely eliminate the interference of these signals on key operations, and it is difficult to effectively reduce the pressure faced by monitoring personnel in their daily monitoring work.

[0004] To deal with the frequent alarms in power systems, the existing technologies have the following shortcomings:

[0005] 1. Too many alarm signals: There are many devices in the power system, and the amount of alarm signals generated is large, which can easily cause information overload for dispatchers and make it difficult to handle all alarms in a timely manner.

[0006] 2. Frequent invalid alarms: Due to equipment aging, improper configuration or environmental factors, a large number of invalid alarms may be generated. These alarms not only occupy resources but also may cover up the truly important alarm information.

[0007] 3. Unclear alarm classification: Existing alarm systems often lack an effective classification mechanism, which causes important alarms and minor alarms to be mixed together, increasing the difficulty for dispatchers to identify and handle them.

[0008] 4. Lack of intelligent analysis: Traditional alarm systems can usually only perform simple threshold judgments, lack in-depth analysis and mining of alarm data, and cannot provide higher-level decision support.

[0009] 5. Slow response: When alarms are frequent, traditional manual processing methods are inefficient and take a long time to respond, which may result in important issues not being resolved in a timely manner.

[0010] 6. Insufficient professional collaboration: Information sharing and collaborative work between different departments are not sufficient, which may lead to duplication of work or omission of important information in the alarm processing process.

[0011] 7. Imperfect management system: The alarm signal defect management system process is not perfect and lacks standardized processing procedures, which affects the overall processing efficiency and effectiveness.

[0012] 8. Poor user experience: The alarm interface is not designed reasonably, the operation is complicated, and the user-friendliness is poor, which affects the dispatcher's work efficiency and experience. Summary of the invention

[0013] In order to solve the deficiencies in the prior art, the present invention provides an intelligent shunting method based on frequent alarms of power grid signals. The method can automatically count and display the number of frequent alarms. When the number of alarms in a certain period exceeds a preset threshold, it automatically enters the intelligent shunting process, pops up a frequent alarm window, and promptly reminds the monitoring personnel to take further measures.

[0014] The present invention adopts the following technical solution.

[0015] A first aspect of the present invention provides an intelligent traffic diversion method for frequent alarms, comprising the following steps:

[0016] Configure frequent alarm identification rules, identify frequent alarm signals based on the rules, push the identified frequent alarm signals to the frequent alarm window, form a frequent alarm table, and continue to perform intelligent diversion and disposal of frequent alarms, including diversion into unprocessed, short-term disposal and long-term disposal, and handle them with different strategies;

[0017] Alarms that have just been identified as frequent alarm signals and have not yet been further processed are classified as unprocessed, reminding monitoring personnel of the frequent alarm signals and making further diversion and disposal, including continuing to divert to short-term disposal, long-term disposal, and no disposal required;

[0018] When an alarm enters the short-term handling phase, the alarm handling urgency level is marked, and the alarm is converted to long-term handling, fault elimination, or restored to the regular alarm handling process.

[0019] When an alarm enters the long-term disposal phase, the original alarm that occurs again will be processed as a stop alarm and will not enter any real-time alarm table, but will only be written into the historical event record table.

[0020] Preferably, the frequent alarm identification rule includes: a signal type condition and a signal frequency condition;

[0021] The signal type condition is used to automatically determine whether the type of the original alarm signal received belongs to the signal type that requires diversion processing; the signal frequency condition is used to automatically determine whether the frequency of occurrence of the original alarm received triggers diversion processing; alarms that do not meet any of the signal type conditions and signal frequency conditions will not enter the diversion processing and will be processed as regular alarm information.

[0022] Preferably, responsibility conditions are configured in the frequent alarm identification rules, and the types of frequent alarm signals to be monitored in the signal types are divided according to monitoring responsibilities, so as to further divert the monitoring and handling of frequent alarms.

[0023] Preferably, the alarms classified as unhandled links are further diverted and handled, including: setting an automatic handling threshold, when the number of alarms exceeds the threshold, the signal is automatically transferred from the unhandled link to the short-term handling link, and the subsequent original alarms will only update the short-term handling link statistics; or,

[0024] Manual operations further divide the unhandled alarms into short-term handling, long-term handling, and no handling required;

[0025] Automatically generate operation alarm records representing automatic operations and manual operations.

[0026] Preferably, in the short-term handling link, for short-term handling alarms, the original alarm that occurs again will be automatically diverted to the test alarm table and will no longer be displayed in the regular alarm window, for automatic shielding of frequent signals.

[0027] Preferably, in the short-term disposal phase,

[0028] Transfer to long-term disposal: After transfer to long-term disposal, the alarm signal will be transferred to the long-term disposal stage and marked as stop alarm. The alarm will be removed from the test alarm table and the test status will be cleared.

[0029] Fault elimination: After selecting fault elimination, the alarm signal will be deleted from the frequent alarm window, the alarm will be removed from the test alarm table, and the test status will also be cleared;

[0030] Restore alarm: After selecting Restore alarm, the alarm signal will not be deleted from the frequent alarm window, but the alarm will be removed from the test alarm table, the test status will be cleared, and the alarm will resume normal display and processing;

[0031] Alarm level: Set multiple alarm handling urgency levels and distinguish them by color display.

[0032] Preferably, in the long-term treatment link, the operation on the alarm includes: transferring to short-term treatment, troubleshooting, alarm recovery or modifying the alarm level, wherein:

[0033] Fault elimination processing: After selecting fault elimination processing, the alarm signal will be deleted from the frequent alarm window. If it is in the test state before the fault is eliminated, the test state will be cleared; if it is in the stop alarm state before the fault is eliminated, the stop alarm state will be cleared;

[0034] Restore alarm: After selecting restore alarm, the alarm signal will not be deleted from the frequent alarm window. If it is in the test state before the fault is eliminated, the test state will be cleared. If it is in the stop alarm state before the fault is eliminated, the stop alarm state will be cleared to restore the alarm to normal display and processing;

[0035] Alarm level: Set multiple alarm handling urgency levels and distinguish them by color display.

[0036] Preferably, for alarms that enter the unprocessed, short-term processed or long-term processed stages, when the original alarm occurs again, the alarm count displayed in the frequent alarm window is automatically updated;

[0037] The frequency level is automatically adjusted and displayed according to the frequency of alarm occurrence.

[0038] A second aspect of the present invention provides an intelligent traffic diversion and handling system for frequent alarms, comprising:

[0039] Frequent alarm identification module, with built-in frequent alarm identification rules, is used to detect frequent alarm signals; push frequent alarms to the frequent alarm window, perform intelligent diversion and disposal, and push non-frequent alarms to the regular alarm window;

[0040] The frequent alarm window includes: unhandled tab, short-term handling tab and long-term handling tab, which handle frequent alarms with different strategies respectively;

[0041] Regular alarm window: used to display and process alarms that are not pushed to the frequent alarm window, and to display the handling operation records of the frequent alarm window.

[0042] Preferably, each tab page of the frequent alarm window displays the frequent alarms with set fields, including: alarm level, plant name, address, first frequent occurrence time, number of times and disposal status.

[0043] Compared with the prior art, the beneficial effects of the present invention include at least: by introducing intelligent and automated technologies, the automation level of power system dispatching can be significantly improved. This not only effectively reduces the workload of power grid monitoring personnel, but also greatly improves their efficiency in handling frequent alarms. At the same time, through effective management and rapid response to alarm information, the safe and stable operation of the power grid is ensured, and the potential risks caused by failure to handle alarms in a timely manner are reduced. In addition, the system can also help to reasonably allocate resources, so that limited manpower and material resources can be concentrated on the most critical issues, thereby further enhancing the overall stability and reliability of the power system.

[0060] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0061] It is understandable that with the continuous advancement of the process of integrated power grid control, the problems of imperfect equipment alarm signal management process and insufficient professional collaboration have become increasingly prominent. Frequent signals are usually caused by defects in primary equipment. Such frequent signals not only seriously interfere with the normal monitoring work of monitoring personnel, but also occupy a large amount of system resources, affecting the stable operation of the system. In order to solve this problem, reduce the workload of monitoring personnel, and optimize the signal processing of the system, it is necessary to effectively identify and handle frequent signals on site. Based on a full understanding of technical issues, the present invention is committed to giving full play to the advantages of integrated control, avoiding the concealment of key information due to too many invalid or erroneous signals, thereby affecting the stable operation of the system and the safety of power grid equipment, and providing effective technical means to realize the intelligent diversion and disposal of frequent alarm signals.

[0062] like Figure 1 As shown, embodiment 1 of the present invention provides an intelligent diversion method for handling frequent alarms. The intelligent diversion method for handling frequent alarms specifically includes the following steps:

[0063] Step 1: Configure frequent alarm identification rules, such as Figure 2 As shown, based on the rule, frequent alarm signals are identified, and frequent alarm intelligent diversion and disposal are continued for the identified frequent alarm signals, including diversion into three categories: unhandled, short-term disposed and long-term disposed, and different strategies are used for processing respectively.

[0064] Preferably but not restrictively, for the original alarm received, the frequent alarm identification rules include: signal type conditions and signal frequency conditions; wherein, the signal type conditions are used to determine whether the type of the original alarm signal received belongs to the signal type that requires diversion processing; the signal frequency conditions are used to determine whether the frequency of occurrence of the original alarm received triggers diversion processing; alarm signals that do not meet any of the signal type conditions and the signal frequency conditions do not enter the diversion processing and are processed as regular alarm information.

[0065] Preferably but not restrictively, any type of signal can be configured to join the frequent alarm intelligent diversion processing, and the frequent identification threshold can be set for different types of signals, that is, different signal frequency conditions are set for different types of signals.

[0066] Preferably but not restrictively, the frequency condition in the frequent alarm identification rule is implemented by configuring the intelligent alarm counting rule. The specific configuration interface is as follows: Figure 2 This intelligent processing method not only improves the efficiency of alarm management, but also effectively reduces the workload of monitoring personnel, ensuring that important alarm information can be paid attention to and processed in a timely manner.

[0067] By way of example but not limitation, based on the intelligent alarm counting function, the system can monitor and process alarm signals that occur 4 times or more within 1 hour, or 10 times or more within 24 hours. It is understandable that these parameters can be set according to actual needs. When the set conditions are met, the system will generate an alarm for the frequent signals and push them to the frequent alarm window so that the monitoring personnel can view and handle them in time.

[0068] Further preferably but not restrictively, for an alarm signal that has been determined to be a frequent alarm, subsequent alarms of the alarm signal are suppressed to reduce interference from invalid alarms.

[0069] Further preferably but not restrictively, responsibility conditions are configured in the frequent alarm identification rules, and the types of frequent alarm signals to be monitored in the signal types are divided according to monitoring responsibilities, so as to further divert the monitoring and disposal of frequent alarms. Specifically, since the division of on-site responsibility areas is more detailed, and the dispatchers in different responsibility areas have different monitoring responsibilities, it is necessary to divide the frequent signals into responsibility areas so that the dispatchers in each responsibility area can monitor and handle the frequent signals in a targeted manner. To this end, a configuration item is added to allow the user to set whether to enable the responsibility area diversion function in the frequent alarm window. The specific configuration interface is as follows: Figure 3 It is worth noting that this design helps improve monitoring efficiency and ensures that the dispatcher in each responsible area can focus on alarm processing in his or her responsible area.

[0070] Step 2: Alarms that have just been identified as frequent alarm signals and have not yet been further processed are classified as unhandled links, and the frequent alarm window is used to remind monitoring personnel of the occurrence of frequent alarm signals. The frequent alarm signals classified as unhandled links are further diverted and handled, including continued diversion to short-term handling, long-term handling, and no handling required.

[0071] Preferably, but not restrictively, within a certain period, if the number of alarms exceeds a preset frequency threshold, the diversion process is automatically triggered and the alarm is classified as an unhandled link, and a frequent alarm window is automatically popped up to remind monitoring personnel that the signal is frequent. If the original alarm that occurs again has not reached the automatic handling threshold and has not been manually transferred to short-term handling, it will still enter the all alarm table and be displayed in the regular alarm window.

[0072] Preferably but not restrictively, alarms classified as unhandled are further diverted and handled, including: setting an automatic handling threshold, when the number of alarms exceeds the threshold, automatically transferring the signal from the unhandled stage to the short-term handling stage, and the subsequent recurrence of the original alarm will only update the short-term handling stage statistics; or, manually operate to further divert alarms in the unhandled stage into short-term handling, long-term handling, and no handling required, and automatically generate operation alarm records representing automatic operations and manual operations.

[0073] Further preferably but not restrictively, when frequent alarms are generated, the system will automatically push a frequent alarm window. If the statistical number of frequent alarms reaches the preset automatic handling threshold and no manual handling has been performed, in order to avoid the frequent alarms affecting the monitoring work, the system will automatically transfer the alarm to short-term handling. At the same time, the system will send an operation alarm record, in which the operator field is filled in as "(automatic handling)" to distinguish manual handling operations. In addition, in the frequent alarm window, the alarm will be annotated and marked as "automatic handling".

[0074] The configuration of automatic disposal threshold parameters is as follows Figure 4 If the automatic handling threshold is not configured, no automatic handling will be performed. It is worth noting that this design ensures that the system can automatically handle frequent alarms without manual intervention, thereby reducing the workload of monitoring personnel and maintaining the stable operation of the system.

[0075] Further preferably but not restrictively, in the unhandled phase, short-term handling, long-term handling or no handling and other manual operations are performed on the frequent alarms, such as Figure 5 As shown, specifically:

[0076] 1) Short-term disposal: After selecting short-term disposal, the alarm signal will be transferred to the short-term disposal link and marked as "test" status. The processed alarm information will be displayed in the test alarm window without affecting the regular monitoring work.

[0077] 2) Long-term disposal: After selecting long-term disposal, the alarm signal will be transferred to the long-term disposal link and marked as "stop alarm". The processed alarm information will no longer appear in any real-time alarm window, and only historical records will be retained to ensure that it does not affect normal monitoring.

[0078] 3) No action required: After selecting No action required, the alarm signal will be deleted from the Unhandled window and no further processing will be performed. It will be displayed as a regular alarm.

[0079] Preferably, but not restrictively, there are two ways to open the frequent alarm window: (1) when the system recognizes that the signal is frequent, the frequent alarm window pops up automatically; (2) the monitoring personnel manually opens the frequent alarm window through the conventional alarm window.

[0080] Step 3: When the alarm enters the short-term handling stage, the monitoring personnel can mark the urgency level of the alarm based on the decision support information, and choose to convert the alarm to long-term handling, perform defect elimination, or restore to the regular alarm handling process.

[0081] As mentioned above, short-term handling alarms include two situations: one is the alarm that is manually transferred from the unhandled link to the short-term handling link, and the other is the alarm that the system automatically transfers to the short-term handling link when the number of alarms exceeds the preset automatic handling threshold. Preferably, but not restrictively, for short-term handling alarms, the original alarm that occurs again will be automatically diverted to the test alarm table and will no longer be displayed in the regular alarm window, thereby realizing automatic shielding of frequent signals.

[0082] Preferably, but not restrictively, in the short-term handling phase, a manual operation such as long-term handling, fault elimination, alarm recovery or modification of alarm level is performed on the designated alarm, such as Figure 6 As shown, specifically:

[0083] 1) Long-term disposal: After selecting long-term disposal, the alarm signal will be transferred to the long-term disposal interface and marked as stop alarm. At the same time, the test status will be cleared.

[0084] 2) Fault elimination: After selecting fault elimination, the alarm signal will be deleted from the frequent alarm window and the test status will also be cleared.

[0085] 3) Restore alarm: After selecting restore alarm, the alarm signal will not be deleted from the frequent alarm window, but the test status will be cleared, so that the alarm can be displayed and processed normally again.

[0086] 4) Alarm level: Three alarm handling urgency levels can be set and distinguished by color display. Preferably, but not limited to, general: the first field is displayed in green; important: the first field is displayed in dark red; urgent: the first field is displayed in dark red.

[0087] Step 4: Long-term disposal alarms refer to those alarms that are manually converted to long-term disposal status after entering the unprocessed or short-term disposal stage. For long-term disposal alarms, the original alarm that occurs again will be stopped, and only the alarm count will be updated. It will not enter any real-time alarm table, but only be written into the historical event record table.

[0088] Preferably, but not restrictively, in the long-term processing link, short-term processing, fault elimination, alarm recovery or modification of alarm level and other manual operations are performed on the designated alarm, such as Figure 7 As shown, specifically:

[0089] 1) Short-term disposal: After selecting short-term disposal, the alarm signal will be transferred to the short-term disposal interface and marked as a test alarm, and the stop alarm status will be cleared.

[0090] 2) Fault elimination: After selecting fault elimination, the alarm signal will be deleted from the frequent alarm window and the stop alarm status will be cleared.

[0091] 3) Restore alarm: After selecting Restore alarm, the alarm signal will not be deleted from the frequent alarm window, but the stop alarm mark will be cleared, so that the alarm will resume normal display and processing.

[0092] 4) Alarm level: Three alarm handling urgency levels can be set and distinguished by color display. Preferably, but not limited to, general: the first field is displayed in green; important: the first field is displayed in dark red; urgent: the first field is displayed in dark red.

[0093] Preferably but not restrictively, for alarms that enter the unprocessed, short-term processed or long-term processed stages, the number of alarms displayed in the frequent alarm window will be automatically updated whenever a new alarm occurs. Depending on the frequency of the alarm, its status is automatically adjusted and displayed as low frequency, medium frequency or high frequency.

[0094] Specifically, two columns (frequency and alarm group) are added to the frequent alarm window to distinguish the frequency of alarms and classify them into high frequency, medium frequency and low frequency. The specific frequency parameter configuration is as follows Figure 8 By combining frequency information and alarm group display, more effective handling decision support can be provided to monitoring staff on duty. This helps monitors distinguish the level of signals and their processing priorities, so that they can handle them more efficiently. The actual display effect of frequent alarms is shown in Fig. 9It is worth noting that this design not only enhances the visualization of alarm information, but also improves the efficiency and accuracy of monitoring work.

[0095] Further preferably but not restrictively, the frequent alarm handling interface provides an export button, and the user can click the button to export the relevant information of all frequent alarms on the current page. It is worth noting that this design facilitates the user to export the data of frequent alarms for further analysis or archiving, thereby improving work efficiency.

[0096] The handling operation records of frequent alarms will be displayed in the general window, such as Fig.10 It is worth noting that this design makes it easy for users to view and track the processing of frequent alarms in the regular window, thereby improving the efficiency of monitoring and management.

[0097] Embodiment 2 of the present invention provides an intelligent diversion and disposal system for frequent alarms. The system can receive remote signal alarm messages in real time, and perform graded processing on the signals according to their importance and frequency of occurrence, and generate corresponding frequent alarm information to remind monitoring personnel. At the same time, the system will set marks for the measurement points of frequent signals so that more detailed alarm processing can be performed based on these mark bits in the future. In addition, the system will pop up a special frequent alarm window for monitoring personnel to view in time and take corresponding measures to deal with it.

[0098] The system provides the following functions:

[0099] 1) Automatic identification of frequent signals.

[0100] 2) Frequent signal handling, including frequent comprehensive alarms, short-term handling, long-term handling, automatic handling, fault elimination, alarm recovery and alarm export.

[0101] 3) Frequent signal counting statistics and lists.

[0102] Specifically, the intelligent diversion and handling system for frequent alarms includes:

[0103] The frequent alarm identification module has built-in frequent alarm identification rules to detect whether the alarm signal is a frequent alarm signal; push frequent alarms to the frequent alarm window, perform intelligent diversion and disposal, and push non-frequent alarms to the regular alarm window;

[0104] The frequent alarm window includes: unprocessed labels, short-term processing labels and long-term processing labels, and handles frequent alarms with different strategies. Fig.11 As shown;

[0105] The regular alarm window is used to display and process alarms that are not pushed to the frequent alarm window; the handling operation records of frequent alarms will be displayed in the regular window operation alarm label. This design makes it easier for users to view and track the handling of frequent alarms in the regular window, improving the efficiency of monitoring and management.

[0106] The frequent alarm identification module includes: a configurable category detection unit and a frequency detection unit. The category detection unit determines whether the received alarm signal type belongs to the signal type that needs to be diverted according to the signal type condition; the frequency detection unit determines whether the frequency of the received alarm signal type meets the requirements for entering the diversion process according to the signal frequency condition.

[0107] Alarm signals that do not meet any of the signal type conditions and signal frequency conditions will not enter the diversion process, but will be pushed to the regular alarm window and processed as regular alarm information.

[0108] By way of example but not limitation, based on the intelligent alarm counting function, the frequent alarm identification module can monitor and process alarm signals that occur 4 times or more within 1 hour, or 10 times or more within 24 hours. It is understandable that these parameters can be set in the frequent alarm identification module according to actual needs. When the set conditions are met, the frequent alarm identification module will generate an alarm for the frequent signals and push it to the frequent alarm window so that the monitoring personnel can view and deal with it in time. In addition, the suppression function of the subsequent alarms of the signal by the frequent alarm identification module can reduce the interference of invalid alarms.

[0109] Further preferably but not restrictively, the frequent alarm identification module also includes: a responsibility area diversion configuration unit, which divides the frequent signals into responsibility areas, for further diverting the monitoring and handling of frequent alarms. Specifically, since the division of responsibility areas on site is more detailed, and the monitoring responsibilities of dispatchers in different responsibility areas are different, it is necessary to divide the frequent signals into responsibility areas so that the dispatchers in each responsibility area can monitor and handle the frequent signals in a targeted manner. To this end, the system adds a configuration item that allows users to set whether to enable the responsibility area diversion function in the frequent alarm window. This design helps to improve monitoring efficiency and ensure that dispatchers in each responsibility area can focus on alarm processing in their area of ​​responsibility.

[0110] For the three tabs of Unprocessed, Short-term Processed and Long-term Processed, Fig.12 , Fig.13 and Fig.14 As shown in the figure, different alarm diversion processing strategies are designed respectively: for alarms that enter the unprocessed, short-term processing or long-term processing window, the number of alarms displayed in the frequent alarm window will be automatically updated every time a new alarm occurs. According to the frequency of alarm occurrence, the system will automatically adjust and display its status as low frequency, medium frequency or high frequency.

[0111] The unhandled label is used to display and process unhandled alarms. Within a certain period, if the number of alarms exceeds the preset frequency threshold, the system will automatically trigger the diversion process, classify the signal into the unhandled label window, and automatically pop up the frequent alarm window to remind the monitoring personnel that the signal is frequent. If the original alarm occurs again, if the number has not reached the automatic handling threshold and has not been manually transferred to short-term handling, it will still enter the all alarm table and be displayed in the regular alarm window.

[0112] Further preferably but not restrictively, an automatic handling threshold is set. When the number of alarms exceeds the threshold, the system automatically transfers the signal from the unhandled tab to the short-term handling tab. Subsequent alarms will only update the short-term handling tab statistics.

[0113] When frequent alarms are generated, the system will automatically pop up a frequent alarm window. If the number of frequent alarms reaches the preset automatic handling threshold and no manual handling has been performed, the system will automatically transfer the alarm to short-term handling to avoid frequent alarms affecting the monitoring work. At the same time, the system will send an operation alarm record, in which the operator field is filled in as (automatic handling) to distinguish manual handling operations. In addition, in the frequent alarm window, the alarm will be annotated and marked as automatically handled.

[0114] If the automatic handling threshold is not configured, no automatic handling will be performed. This design ensures that the system can automatically handle frequent alarms without manual intervention, thereby reducing the workload of monitoring personnel and maintaining stable operation of the system.

[0115] Further preferably but not restrictively, in the unhandled tab page, manual operations such as short-term handling, long-term handling or no handling are performed on the frequent alarms.

[0116] 1) Short-term disposal: After selecting short-term disposal, the alarm signal will be transferred to the short-term disposal interface and marked as test status. The processed alarm information will be displayed in the test alarm window without affecting the regular monitoring work.

[0117] 2) Long-term disposal: After selecting long-term disposal, the alarm signal will be transferred to the long-term disposal interface and marked as stop alarm. The processed alarm information will no longer appear in any real-time alarm window, and only the historical records will be retained to ensure that it does not affect normal monitoring.

[0118] 3) No action required: After selecting No action required, the alarm signal will be deleted from the Unhandled tab page, and no further processing will be performed, and it will be displayed as a regular alarm.

[0119] The short-term handling tab is used to display and process short-term handling alarms, including: when an alarm enters the short-term handling tab, the monitoring personnel can mark the alarm handling urgency level based on the decision support information, and choose to convert the alarm to long-term handling, perform defect elimination, or restore to the regular alarm handling process.

[0120] Specifically, short-term disposal alarms include two situations: one is the alarm that is manually converted to short-term disposal from the unresolved tab; the other is the alarm that is automatically converted to short-term disposal status by the system when the number of alarms exceeds the preset automatic disposal threshold.

[0121] For short-term handling alarms, the original alarm that occurs again will be automatically diverted to the test alarm table and will no longer be displayed in the regular alarm window, thereby achieving automatic shielding of frequent signals.

[0122] Further preferably but not restrictively, in the short-term handling tab page, manual operations such as long-term handling, fault elimination, alarm recovery or modification of alarm level are performed on the designated alarm.

[0123] 1) Long-term disposal: After selecting long-term disposal, the alarm signal will be transferred to the long-term disposal interface and marked as stop alarm. At the same time, the test status will be cleared.

[0124] 2) Fault elimination: After selecting fault elimination, the alarm signal will be deleted from the frequent alarm window and the test status will also be cleared.

[0125] 3) Restore alarm: After selecting restore alarm, the alarm signal will not be deleted from the frequent alarm window, but the test status will be cleared, so that the alarm can be displayed and processed normally again.

[0126] 4) Alarm level: Three alarm handling urgency levels can be set and distinguished by color display. Preferably, but not limited to, general: the first field is displayed in green; important: the first field is displayed in dark red; urgent: the first field is displayed in dark red.

[0127] The long-term disposal tab is used to display and process long-term disposal alarms. Specifically, long-term disposal alarms refer to those alarms that are manually converted to long-term disposal status after entering the unresolved tab or short-term disposal tab.

[0128] For long-term processing alarms, the original alarm that occurs again will be processed as a stop alarm and will not enter any real-time alarm table, but will only be written into the historical event record table.

[0129] In the long-term disposal tab, manual operations such as short-term disposal, fault elimination, alarm recovery, or modification of alarm levels are supported for specified alarms.

[0130] 1) Short-term disposal: After selecting short-term disposal, the alarm signal will be transferred to the short-term disposal interface and marked as a test alarm, and the stop alarm status will be cleared.

[0131] 2) Fault elimination: After selecting fault elimination, the alarm signal will be deleted from the frequent alarm window and the stop alarm status will be cleared.

[0132] 3) Restore alarm: After selecting Restore alarm, the alarm signal will not be deleted from the frequent alarm window, but the stop alarm mark will be cleared, so that the alarm will resume normal display and processing.

[0133] 4) Alarm level: Three alarm handling urgency levels can be set and distinguished by color display. Preferably, but not limited to, general: the first field is displayed in green; important: the first field is displayed in dark red; urgent: the first field is displayed in dark red.

[0134] Each tab of the Frequent Alarms window displays frequent alarms with specific fields, including:

[0135] 1) Level color: Associated with the last field "Signal Level", it includes three levels: general, important, and urgent, and is represented by different colors.

[0136] 2) Plant name: The name of the plant to which the alarm belongs.

[0137] 3) Address: It consists of two numbers separated by a colon. The first number indicates the RTU address of the plant station, and the second number indicates the address of the signal in the RTU.

[0138] 4) First frequent occurrence time: the time when the signal begins to be judged as frequent.

[0139] 5) Number of times: The cumulative number of times the signal occurs since the first occurrence.

[0140] 6) Disposal status: The current disposal status of frequent alarms, including short-term disposal, long-term disposal and alarm recovery.

[0141] 7) Signal level: The monitoring personnel set it according to the urgency of the signal, which is divided into three levels: general, important and emergency.

[0142] Preferably, but not restrictively, there are two ways to open the frequent alarm window: (1) when the system recognizes that the signal is frequent, the frequent alarm window pops up automatically; (2) the monitoring personnel manually opens the frequent alarm window through the conventional alarm window.

[0143] Specifically, the automatic pop-up method: when the system detects a new frequent alarm, the node configured with the pop-up window will automatically pop up the frequent alarm window. Fig.15 shown.

[0144] Manual opening method: The monitoring personnel can manually open the frequent alarm window by selecting the "Frequent Alarm Window" option in the alarm right-click menu through the regular alarm window. The specific operation steps are as follows: Fig.16 shown.

[0145] Preferably, but not restrictively, the frequent alarm window further includes an export unit. Specifically, the handling interface of the frequent alarm window provides an export button, and the user can click the button to export the relevant information of all frequent alarms on the current page. This design facilitates the user to export the data of frequent alarms for further analysis or archiving, thereby improving work efficiency.

[0146] Preferably, but not restrictively, the frequent alarm window also includes a grading unit for distinguishing the frequency of alarms. Specifically, the grading unit adds two columns (frequency and alarm group) in the frequent alarm window to distinguish the frequency of alarms, classifying them into high frequency, medium frequency and low frequency. By combining the frequency information and the alarm group display, more effective handling decision support can be provided for monitoring duty personnel. This helps the monitor to distinguish the level of the signal and its processing priority, so that priority handling can be performed more efficiently. This design not only enhances the visualization of the alarm information, but also improves the efficiency and accuracy of the monitoring work.

[0147] In summary, the present invention provides an intelligent diversion and disposal method and system for alarms based on frequent power grid signals with outstanding substantive characteristics, covering a number of technologies such as signal frequent occurrence identification, automatic disposal, alarm shielding, alarm cessation, frequent occurrence statistics and real-time display. The method and system support manual secondary disposal, including operations such as marking the urgency of the signal, flexible conversion of long-term and short-term disposal strategies, restoration of alarms, and fault elimination. In addition, different frequent occurrence identification thresholds can be set for different types of signals, which can meet the specific needs of users in different regions and scenarios. When the number of signal occurrences exceeds the set frequent occurrence threshold, the alarm will automatically enter the intelligent diversion disposal process to avoid frequent signals from interfering with normal monitoring work, and at the same time provide necessary decision-making support for the on-duty personnel in the disposal of frequent signals.

[0148] The technical solution of the intelligent shunting method and system for frequent alarms provided by the present invention has been successfully applied in engineering in multiple non-public projects. Practice has proved that the present invention can significantly reduce the adverse effects of frequent signals on monitoring work, help on-duty personnel to timely discover and process important information in the power grid in massive alarms, greatly reduce the pressure of monitoring, and thus improve the work efficiency of on-duty personnel.

[0149] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
