[0045] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be given later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0046] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present application. On the contrary, they are merely examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] In the related art, after the substation equipment trips, it mainly relies on the operation and maintenance personnel to go to the site for inspection to collect data and analyze the data. However, the complexity of substation equipment faults and the diversity of data lead to lower efficiency of traditional manual data collection and analysis, and it is impossible to quickly and accurately identify the cause of the fault, thus affecting the fault handling efficiency and the safe and stable operation of the power grid.

[0048] In view of the above technical problems, the substation equipment fault tripping monitoring system provided by the present application, through the coordinated action of the data acquisition system, the tripping judgment system and the tripping analysis system, is fully automated to execute, improving the timeliness of data collection and shortening the fault troubleshooting time; and when detecting the alarm of the substation and the position change information of the switch, it intelligently analyzes whether it is a fault tripping and screens out the tripping events caused by human operations; further, it only deeply analyzes the fault tripping events without operation and maintenance records to generate a fault tripping report, reducing the processing of redundant data, thereby improving the fault troubleshooting efficiency and enhancing the response speed of fault handling.

[0049] The following uses specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0050] Figure 1 Structure schematic of the substation equipment fault tripping monitoring system provided by the embodiments of the present applicationFigure 1 , as Figure 1 shown, the substation equipment fault trip monitoring system provided in this embodiment includes: a data acquisition system 11, a trip judgment system 12, and a trip analysis system 13; where:

[0051] The data acquisition system 11 is used to acquire the system operation data of the power grid system; and when it detects that the system operation data contains the alarm information of the target substation and the position change information of the switches in the target substation, it sends the alarm information and the position change information to the trip judgment system 12, and the alarm information contains a timestamp.

[0052] Among them, the system operation data is used to assist in the online monitoring and fault analysis of the substation equipment trip. For example, it includes real-time monitoring data (equipment status potential information, load data, current, voltage, protection information, interval light signal information, intelligent wave recording data, etc.), meteorological data (such as weather information in the area where the main power transmission and transformation network of the power grid is located, lightning strike location information, etc.), and operation and maintenance work data of substation equipment (such as work tickets carried out in the station on the same day, operation tickets for switching operations on the same day, historical defect conditions, patrol and maintenance records, etc.).

[0053] The switches in the substation include equipment such as circuit breakers and disconnectors, which are used to control the connection and disconnection of the circuit. For example, a circuit breaker can cut off the current during a fault to protect other equipment.

[0054] Exemplarily, the data acquisition system 11 acquires real-time monitoring data from the power grid dispatching data center, acquires meteorological data from the local meteorological bureau or the power grid meteorological service system, and acquires operation and maintenance work data of substation equipment from the power grid management platform. It can also acquire real-time stored system operation data from other servers or databases.

[0055] The data acquisition system 11 performs real-time detection of the alarm of the target substation and the position change information of the switches in the target substation on the acquired system operation data. For example, during the operation of the power grid system, if a trip event occurs in Substation A, at this time, the alarm information of Substation A can be detected in the system operation data. The alarm information may include the timestamp of the trip event, the substation identifier of Substation A, and the alarm content (trip). At the same time, the position change information of the switches that trip in Substation A can also be detected. There may be multiple switches that trip, so there may be one or more switch position change information. Among them, the position change information at least includes a switch identifier (such as a unique identifier such as a switch name and a switch number), and may also include a position change type (opening / closing), a timestamp, etc. For example, the position change information includes that Switch A-2# is in the open state, that is, the switch that trips in Substation A is Switch A-2#.

[0056] A tripping judgment system 12 is used to determine whether there is an operation and maintenance record corresponding to a time stamp. The operation and maintenance record includes the operation and maintenance record of the switch and / or the operation and maintenance record of the substation equipment associated with the switch. If not, it is determined that the switch has a faulty trip, and the time stamp and the target switch identifier of the switch are sent to the tripping analysis system 13.

[0057] Among them, the operation and maintenance record can be stored in the tripping judgment system 12, a server communicating with the tripping judgment system 12, or other systems docked with the tripping judgment system 12, and the operation and maintenance record can be updated regularly. When receiving the alarm information and the position change information sent by the data acquisition system 11, the operation and maintenance record can be retrieved from the memory or database of the tripping judgment system 12, or obtained from a server communicating with the tripping judgment system 12, or obtained from other systems docked with the tripping judgment system 12.

[0058] It can be understood that as a whole, the substation is divided into multiple equipment bays, and specific substation equipment (such as transformers, circuit breakers, etc.) is installed in each equipment bay. The switch, as a part of the substation equipment, is installed in the equipment bay and is used to control the on-off of the circuit to protect the substation equipment. Therefore, when performing manual operation and maintenance on the switch or performing manual operation on the substation equipment associated with the switch, it may cause the switch to open (i.e., trip).

[0059] Exemplarily, in response to receiving the alarm information and the position change information sent by the data acquisition system 11, the tripping judgment system 12 searches in the operation and maintenance record according to the time stamp in the alarm information and the switch identifier of the switch, and determines whether there is an operation and maintenance record for the switch identifier and / or the substation equipment associated with the switch identifier within a certain time range before and after the time stamp. If it exists, it is determined that the non-faulty trip event of the switch is caused by manual operation, such as switching operation, planned maintenance of substation equipment, etc., and there is no need to further investigate the cause of the trip. If not, it is determined that the faulty trip event is caused by non-manual operation, and the cause of the trip needs to be further investigated. At this time, the time stamp carried in the alarm information and the target switch identifier of the switch are sent to the tripping analysis system 13 for analyzing the cause of the trip through the tripping analysis system 13.

[0060] A tripping analysis system 13 is used to determine the system operation data of the target substation within the first preset time period corresponding to the time stamp according to the target switch identifier, and generate a fault trip report of the switch.

[0061] Among them, the first preset time period can be preset according to the fault type to ensure that key event data is covered. It should be noted that this application does not make specific restrictions on the first preset time period, as long as the key event data can be covered within this time period.

[0062] Exemplarily, in response to receiving the timestamp sent by the trip judgment system 12 and the target switch identifier of the switch, the trip analysis system 13 obtains the target substation corresponding to the target switch identifier from the data acquisition system 11, and the system operation data within the first preset duration corresponding to the timestamp. For example, the system operation data from 5 minutes before the trip event occurs to 5 minutes after the trip event occurs. And based on the system operation data within the first preset duration, a fault trip report for the switch is generated. For example, the system operation data is subjected to data cleaning, normalization processing, correlation integration processing, and key feature extraction and analysis, and based on the report template, a fault trip report is automatically generated. This fault trip report can assist the operation and maintenance personnel in determining the cause of the fault, and then quickly carry out fault handling.

[0063] Optionally, the fault briefing may further include fault handling suggestions.

[0064] Optionally, the trip analysis system 13 may visually display the fault briefing on the front-end interface of the substation equipment fault trip monitoring system and / or send it to relevant personnel.

[0065] It should be noted that at least one of the data acquisition system 11, the trip judgment system 12, and the trip analysis system 13 can be independently deployed on at least one server. For example, the data acquisition system 11 is deployed on one server; the trip judgment system 12 is deployed on multiple servers, and the multiple servers cooperate to complete the functions of the trip judgment system 12. The server can also be replaced by a server cluster, virtual resources (such as containers), computing devices with a certain computing power, etc. The present application does not limit the deployment form of the acquisition system 11, the trip judgment system 12, and the trip analysis system 13.

[0066] In the embodiment of the present application, by real-time monitoring the system operation data, automatically detecting alarm and switch position change information, timely integrating multi-source data, such as alarm information, switch position change information, and operation and maintenance records, performing correlation judgment on trip events, eliminating human operation interference, and reducing the misjudgment rate of fault trips; in addition, the whole process is automated, reducing labor costs while also improving the data collection timeliness, shortening the fault troubleshooting time, and only deeply analyzing the fault trip events without operation and maintenance records to generate fault trip reports, reducing redundant data processing, thereby improving the fault troubleshooting efficiency, enhancing the response speed of fault handling, reducing the load loss and power outage time after the fault occurs, and ensuring the safe and stable operation of the power grid.

[0067] In some embodiments, the trip analysis system 13 is specifically configured to: determine a target substation according to a target switch identifier based on the mapping relationship between switch identifiers and substations; obtain system operation data of the target substation within a first preset duration corresponding to a time stamp; obtain inspection data for the switch according to the target switch identifier; and generate a fault trip report for the switch according to the inspection data and the system operation data within the first preset duration.

[0068] Exemplarily, a mapping relationship between switch identifiers and substations is preset in the database of the trip analysis system 13. After receiving the time stamp and the target switch identifier of the switch sent by the trip judgment system 12, the target substation corresponding to the target switch identifier is searched for in the mapping relationship with the target switch identifier as the index. The system operation data of the target substation corresponding to the target switch identifier within the first preset duration corresponding to the time stamp can be obtained from the data acquisition system 11. For example, the system operation data from 5 minutes before to 5 minutes after the trip event occurs. In addition, according to the target switch identifier, the specific substation equipment associated with the switch and the equipment bay where the substation equipment is located can be located, and then the inspection data for the switch can be associated. For example, the inspection data can be obtained by querying a database (such as cloud storage, inspection record database), API call, or exported from other equipment management systems, inspection systems, etc. The inspection data includes infrared thermal imaging data (such as temperature abnormal points), visible light images (such as appearance rust, oil leakage, smoke, etc.).

[0069] Data cleaning, standardization processing, correlation integration processing, and key feature extraction and analysis are performed on the obtained inspection data and the system operation data within the first preset duration, and a fault trip report is automatically generated based on the report template.

[0070] In the embodiments of the present application, the on-site situation after a fault trip is collected through inspection data, providing safety suggestions for the accident level of the trip event and fault handling; through the multi-modal information fusion of inspection data and system operation data, the all-round monitoring of substation equipment before and after a fault trip is realized, avoiding the blind area of fault data collection, improving the accuracy of fault trip analysis, providing a more complete and accurate fault trip report, and thus improving the fault handling efficiency.

[0071] See below Figure 2 As shown, in some embodiments, the substation equipment fault trip monitoring system further includes: an intelligent inspection system 14; the trip analysis system 13 is further configured to send an inspection instruction for the switch to the intelligent inspection system 14 to obtain inspection data, and the inspection instruction carries the target switch identifier; the intelligent inspection system 14 is configured to respond to the inspection instruction, and based on the mapping relationship between the switch identifier and the inspection point and the equipment bay, control the intelligent inspection equipment at the inspection point corresponding to the target switch identifier to inspect the equipment bay corresponding to the switch to obtain inspection data.

[0072] For example, after the trip judgment system 12 determines that a switch has a faulty trip, it sends the time stamp of the trip and the target switch identifier of the switch to the trip analysis system 13 to trigger the trip analysis system 13 to send an inspection instruction to the intelligent inspection system 14. Among them, the inspection instruction carries at least the target switch identifier, and may also carry information such as the inspection duration, inspection scope, and priority.

[0073] In the database of the intelligent inspection system 14, a mapping relationship between the switch identifier and the inspection point and the equipment interval is preset. The inspection point is associated with the intelligent inspection device. It can be understood that each intelligent inspection device is responsible for at least one inspection point, and at least one inspection point can be set for each equipment interval. When the intelligent inspection system 14 receives the inspection instruction, it will assign the intelligent inspection device at the inspection point corresponding to the switch identifier to work. The intelligent inspection device inspects the equipment interval corresponding to the switch (for example, temperature measurement, inspection), and returns inspection data such as visible light and infrared photos to the intelligent inspection system 14.

[0074] The intelligent inspection device is, for example, a drone and indoor and outdoor robots.

[0075] In the embodiment of the present application, after a faulty trip occurs, the intelligent inspection system quickly responds to the inspection instruction, assigns the intelligent inspection device to inspect the specified equipment interval, and quickly obtains the inspection data. Compared with manual inspection, it improves the data collection efficiency and saves labor costs; the deep linkage between the intelligent inspection system and the trip analysis system provides richer data judgment basis for the operation and maintenance personnel, thereby improving the fault troubleshooting efficiency and fault handling efficiency.

[0076] Further, in some embodiments, the intelligent inspection system includes: an equipment ledger management module, which is used to establish a mapping relationship between substation equipment, switches and equipment intervals, a mapping relationship between outgoing line intervals and transmission towers outside the substation, and a mapping relationship between the inspection points of intelligent inspection devices and equipment ledger information; a camera management module, which is used to perform network debugging, preset position acceptance and compilation management on the power transmission and transformation cameras; a drone management module, which is used to perform three-dimensional real-scene modeling on the substation, and perform route planning, route splitting, management and risk point verification on the drones; a robot management module, which is used to perform two-dimensional radar modeling on the inside and outside of the substation, and perform inspection point planning, connection and management on indoor and outdoor robots.

[0077] Among them, the intelligent inspection devices include drones, indoor and outdoor robots, cameras inside the substation, and cameras outside the transmission channels of the substation.

[0078] The equipment ledger management module records the ledger information such as the names and numbers of all substation equipment and transmission towers outside the substation in the power grid system. The substation equipment is bound according to the equipment bay where it is located, and the switches are bound according to the equipment bay where they are located to establish the mapping relationship between the substation equipment, switches and equipment bays; the outgoing line bay is bound to the transmission towers outside the substation to establish the mapping relationship between the outgoing line bay and the transmission towers outside the substation; the inspection points of cameras, drones and indoor and outdoor robots are bound to the equipment ledger information to establish the mapping relationship between the inspection points of intelligent inspection equipment and the equipment ledger information. This facilitates the intelligent inspection system to index the inspection points of the corresponding intelligent inspection equipment according to the target switch identifier (name, number), and conduct inspections on a single substation equipment or the equipment bay where it is located, and can also quickly obtain the video data of the transmission channels outside the substation associated with the target switch identifier.

[0079] The camera management module conducts network debugging, preset position acceptance and compilation management on the power transmission and transformation cameras (including cameras inside the substation and cameras on the transmission channels outside the substation).

[0080] The drone management module conducts 3D real - scene modeling of the substation, and conducts flight path planning, flight path splitting, management and risk point verification on the drones. Among them, the drone flight path is planned manually in the 3D real - scene model of the substation; flight path splitting means executing some inspection points of a flight path; risk point verification means automatically calculating the closest distance between the flight path and the obstacles in the 3D real - scene model to determine whether the inspection is safe.

[0081] The robot management module conducts 2D radar modeling of the inside and outside of the substation (including outdoor high - voltage sites and indoor equipment rooms), and conducts inspection point planning, connection and management on indoor and outdoor robots. The inspection points of indoor and outdoor robots are realized by manually remotely controlling the robot to locate and marking points in the 2D radar model, and it also supports manually connecting the inspection points into an inspection path.

[0082] Based on the above - mentioned embodiments, in some embodiments, the tripping analysis system is further used for: obtaining the video data of the target substation within a second preset duration corresponding to the time stamp; generating a fault tripping report of the switch according to the video data, inspection data and system operation data within the first preset duration.

[0083] Among them, the second preset duration can be preset according to the fault type to ensure covering key event data. It should be noted that this application does not make specific limitations on the second preset duration, as long as it can cover key event data within this duration.

[0084] Exemplarily, in response to receiving the timestamp sent by the trip judgment system 12 and the target switch identifier of the switch, taking the target switch identifier as an index, in the mapping relationship between the switch identifier and the substation, the target substation corresponding to the target switch identifier is found, and the trip analysis system 13 obtains the video data of the target substation within the second preset duration corresponding to the timestamp from the intelligent patrol system 14. For example, visible light videos before and after the trip events inside and outside the target substation are obtained for 1 minute to assist in the fault analysis of the substation equipment fault trip.

[0085] Perform data cleaning, standardization processing, correlation integration processing, and key feature extraction and analysis on the obtained video data, patrol data, and system operation data within the first preset duration, and automatically generate a fault trip report based on the report template.

[0086] In the embodiment of the present application, through the collection of video data, a reliable basis is provided for fault tracing. Fault trip data is collected based on various types of intelligent patrol equipment (such as cameras, drones, and indoor and outdoor robots), and multimodal information fusion is performed with system operation data. Compared with a single data dimension, the comprehensiveness and accuracy of fault analysis are improved, providing accurate and reliable reference data for judging the cause of the fault trip, shortening the fault handling time, and thus improving the reliability of the power grid.

[0087] In some embodiments, the operation and maintenance records include substation equipment maintenance information, planned adjustment information of the operation status of substation equipment, and planned adjustment information of the power grid operation mode.

[0088] See below Figure 2 As shown, the substation equipment fault trip monitoring system further includes an operation and maintenance pool system 15 for recording and updating substation equipment maintenance information, the operation status of substation equipment, planned adjustment information of the operation status of substation equipment, and planned adjustment information of the power grid operation mode; correspondingly, the equipment trip judgment system 12 is further configured to obtain the operation and maintenance records of the substation equipment from the operation and maintenance pool system 15.

[0089] Exemplarily, the operation and maintenance inspection pool system 15 includes an operation pool module and a maintenance inspection pool module. Among them, the operation pool module can record the operation status of all substation equipment that has been put into formal operation in the power grid system. The operation status of the substation equipment can include cold standby, hot standby, maintenance, and operation. Each equipment bay records information such as the name, number, and status of the switch and the disconnectors on both sides thereof, and binds them to each other. In the operation pool module, the equipment information (including substation equipment) and operation status of each equipment bay in the power grid system were manually compiled in the early stage, and subsequently, the equipment information (including substation equipment) and operation status of the equipment bay can be automatically updated. For example, the operation and maintenance inspection pool system 15 is docked with the power grid management platform, and can automatically update the equipment information (including substation equipment) and operation status of the equipment bay according to the switching operation plan information and the content information of the daily dispatching operation ticket in the power grid management platform. When carrying out the planned adjustment work of the operation status of substation equipment or the planned adjustment work of the power grid operation mode, the switch may trip due to reasons such as improper parameter setting, the equipment not adapting to the new status, the protection setting value not being updated in time, and the wrong operation sequence. Therefore, the operation pool module also records and updates the planned adjustment information of the operation status of substation equipment and the planned adjustment information of the power grid operation mode, so as to avoid misjudging the tripping caused by the planned adjustment work of the operation status of substation equipment or the planned adjustment work of the power grid operation mode as a fault tripping.

[0090] The maintenance inspection pool module records and updates the maintenance information of substation equipment carried out in the power grid system. For example, the maintenance information of substation equipment obtains the maintenance work order by packing through the firewall from the power grid management platform, and records or updates the maintenance information of substation equipment according to the maintenance work order. The maintenance work order contains information such as the name, number, and status of the equipment to be maintained, and further retrieves the name, number, status of the equipment to be maintained (such as switches, disconnectors, equipment bays, substation equipment), and the status of the maintenance work order (whether it has been terminated) in the maintenance work order through automated fuzzy search.

[0092] In some embodiments, the tripping analysis system is further configured to output a fault tripping report in the form of a voice call or a text message to remind relevant personnel to perform fault handling.

[0093] Exemplarily, after generating a fault trip report, it is pushed to the relevant equipment responsible persons via AI voice call, intranet SMS, and email to remind them to log in to the substation equipment fault trip monitoring system to view and determine specific alarms, and to perform fault handling in a timely manner.

[0094] Optionally, the trip analysis system supports functions such as historical alarm storage, query, and playback.

[0095] In the embodiments of the present application, the fault trip report is sent to relevant personnel via voice call or SMS, enabling relevant personnel to promptly understand the fault trip event and perform fault handling, improving the fault handling speed and enhancing the user experience.

[0096] In some embodiments, the data acquisition system includes: an operation data acquisition module for acquiring real-time monitoring data of the power grid; and when it detects that the real-time monitoring data contains alarm information and position change information, it sends the alarm information and position change information to the equipment trip judgment system; a weather data acquisition module for acquiring weather information and lightning strike location information of key areas of concern; and an operation and maintenance data acquisition module for acquiring work tickets carried out in the station on the day related to the tripped equipment, operation tickets for switch operations on the day, historical defect conditions, inspection and maintenance records, N-1 power grid risks, and basic information data.

[0097] Exemplarily, the real-time monitoring data includes equipment status potential information, load data, current, voltage, protection information, interval light signal information, intelligent waveform recording data, etc., which can be obtained from the power grid dispatching data center. The key areas of concern can be regarded as the power grid equipment and facilities areas of all substation locations and the transmission line corridors outside the stations, that is, the main power transmission and transformation network of the power grid.

The substation equipment fault trip monitoring method includes:

[0106] S301. The data acquisition system acquires the system operation data of the power grid system; when it detects that the system operation data includes the alarm information of the target substation and the position change information of the switch in the target substation, it sends the alarm information and the position change information to the trip judgment system, and the alarm information includes a time stamp.

[0107] S302. The trip judgment system determines whether there is an operation and maintenance record corresponding to the time stamp. The operation and maintenance record includes the operation and maintenance record of the switch and / or the operation and maintenance record of the substation equipment associated with the switch; if not, it determines that the switch has a fault trip, and sends the time stamp and the target switch identifier of the switch to the trip analysis system.

[0108] It should be noted that if there is an operation and maintenance record corresponding to the time stamp, it is determined that the switch has a non-fault trip, and then step S301 is continued to be executed.

[0109] S303. The trip analysis system determines the system operation data of the target substation within the first preset duration corresponding to the time stamp according to the target switch identifier, and generates a fault trip report of the switch.

[0110] The specific implementation manner of the embodiment of the present application is similar to that of the substation equipment fault trip monitoring system, and will not be elaborated here.

[0111] In the embodiment of the present application, by real-time monitoring the system operation data, automatically detecting the alarm and the position change information of the switch, timely integrating multi-source data, such as alarm information, position change information of the switch and operation and maintenance records, performing associated judgment on trip events, eliminating the interference of human operations, reducing the misjudgment rate of fault trips; in addition, the whole process is automated, improving the data collection efficiency, shortening the fault troubleshooting time, and only performing in-depth analysis on the fault trip events without operation and maintenance records to generate a fault trip report, reducing the processing of redundant data, thereby improving the fault troubleshooting efficiency, enhancing the response speed of fault handling, reducing the load loss and power outage time after the fault occurs, and ensuring the safe and stable operation of the power grid.

[0112] Figure 4 is the flow schematic of the substation equipment fault trip monitoring method provided by the embodiment of the present application Figure 2 . As Figure 4 shown, the substation equipment fault trip monitoring method provided in this embodiment includes the following steps:

[0113] S401. The operation data acquisition module acquires the real-time monitoring data of the power grid system.

[0114] The real-time monitoring data includes device status potential information, load data, current, voltage, protection information, bay light signal information, intelligent waveform recording data, etc., which can be obtained from the power grid dispatching data center.

[0115] S402. The operation data acquisition module detects whether the real-time monitoring data contains both alarm information and change information.

[0116] If it is detected that the real-time monitoring data contains alarm information and change information, execute S403; if not, it means that no substation has tripped currently, and continue to execute S402.

[0117] S403. The operation data acquisition module sends the alarm information and change information to the device tripping judgment system, and the device tripping judgment system obtains the operation and maintenance records of the substation equipment from the operation and maintenance pool system.

[0118] The operation and maintenance records include substation equipment maintenance information, planned adjustment information of substation equipment operation status, and planned adjustment information of power grid operation mode.

[0119] S404. The device tripping judgment system determines whether there is an operation and maintenance record corresponding to the time stamp.

[0120] According to the time stamp in the alarm information and the switch identification of the switch, search in the operation and maintenance records to determine whether there is an operation and maintenance record for the switch identification and / or the substation equipment associated with the switch identification within a certain time range before and after the time stamp.

[0121] If there is, it is determined that the switch has tripped non-faultily, and continue to execute S402; if not, it is determined that the switch has tripped faultily, and execute S405.

[0122] S405. The device tripping judgment system sends the time stamp and the target switch identification of the switch to the tripping analysis system.

[0123] S406. The tripping analysis system obtains the system operation data of the target substation within the first preset duration corresponding to the time stamp from the data acquisition system.

[0124] The tripping analysis system obtains the system operation data of the target substation corresponding to the target switch identification from the data acquisition system within the first preset duration corresponding to the time stamp, for example, the system operation data from 5 minutes before the tripping event occurs to 5 minutes after it occurs.

[0125] S407. The tripping analysis system issues an inspection instruction for the switch to the intelligent inspection system to obtain inspection data, and obtains the video data of the target substation within the second preset duration corresponding to the time stamp.

[0126] Among them, the patrol instruction carries at least the target switch identifier, and may also carry information such as the patrol duration, patrol scope, priority, etc.

[0127] The tripping analysis system responds to the timestamp and the target switch identifier of the switch sent by the tripping judgment system. Using the target switch identifier as an index, in the mapping relationship between the switch identifier and the substation, it finds the target substation corresponding to the target switch identifier, and in the intelligent patrol system, it obtains the video data of the target substation within the second preset duration corresponding to the timestamp. For example, it obtains the visible light video within 1 minute before and after the tripping event inside and outside the target substation to assist in the fault analysis of the substation equipment fault tripping.

[0128] S408. The intelligent patrol system responds to the patrol instruction. Based on the mapping relationship between the switch identifier and the patrol point and the equipment interval, it controls the intelligent patrol equipment at the patrol point corresponding to the target switch identifier to patrol the equipment interval corresponding to the switch, and obtains the patrol data.

[0129] When receiving the patrol instruction, it will assign the intelligent patrol equipment at the patrol point corresponding to the switch identifier to work. The intelligent patrol equipment patrols the equipment interval corresponding to the switch (for example, temperature measurement, inspection), and returns the patrol data such as visible light and infrared photos to the intelligent patrol system.

[0130] S409. The tripping analysis system generates a fault tripping report for the switch according to the video data, patrol data, and system operation data within the first preset duration, and reminds the relevant personnel to perform fault handling by means of voice call or text message.

[0131] For the obtained video data, patrol data, and system operation data within the first preset duration, perform data cleaning, standardization processing, correlation integration processing, and key feature extraction and analysis. Based on the report template, automatically generate a fault tripping report. Push it to the relevant equipment responsible person through AI voice call, intranet text message, and email, reminding them to log in to the substation equipment fault tripping monitoring system to view and determine the specific alarm, and perform fault handling in a timely manner.

Additionally, the entire process is automated, improving the timeliness of data collection, shortening the fault troubleshooting time, and only deeply analyzing fault tripping events without operation and maintenance records to generate fault tripping reports, reducing the processing of redundant data, thereby improving the efficiency of fault troubleshooting, enhancing the response speed of fault handling, reducing the load loss and power outage time after a fault occurs, and ensuring the safe and stable operation of the power grid.
