[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0033] Figure 1 A flowchart of a substation trip analysis method provided by an embodiment of the present invention is applicable to the scenario of substation trip analysis. The method can be executed by a substation trip analysis device, which can be implemented by software and / or hardware and integrated into a computer device with application development function.

[0034] like Figure 1 As shown, the substation tripping analysis method of this embodiment includes the following steps:

[0035] S110. When the substation alarm information of the substation is obtained, the switch state change information of the substation equipment in the substation is obtained.

[0036] The substation alarm information may be the total protection alarm information of the substation, which is used to indicate that a substation protection device or the like has failed. When the substation alarm information of the substation is obtained, the switch state change information of the substation equipment in the substation is obtained from the dispatching data network of the power grid. The switch state change information includes the switching of the switch associated with the substation equipment between the closed state and the open state.

[0037] S120. When the switch state change information is trip information, obtain a target device identifier of a target substation associated with the trip information.

[0038] Determine whether the switch state change information is from the closed state to the open state, if so, the switch state change information is trip information. It is necessary to obtain the target device identification of the target substation associated with the trip information, such as the name or number of the target substation, so that the target device identification can be used to further determine whether the trip information is fault trip information, that is, whether the trip is caused by a fault.

[0039] S130. Obtain target maintenance data of the target substation equipment in the equipment maintenance data warehouse according to the target equipment identifier, and determine the maintenance status of the target substation equipment according to the target maintenance data.

[0040] The equipment maintenance data warehouse stores the maintenance information of substation equipment being carried out in the power grid at the time when the tripping information is obtained. The maintenance information of substation equipment is used to eliminate tripping caused by equipment maintenance or protection inspection.

[0041] Substation equipment maintenance information can be obtained from the equipment maintenance data warehouse through the firewall, including the name, number and status of the maintenance switch and maintenance interval in the maintenance work order. The status of the maintenance work order is whether the maintenance event has been terminated. Substation equipment maintenance information can be obtained through automated fuzzy retrieval of maintenance work orders. The maintenance interval is the interval in the maintenance state. The interval is the substation equipment group in the power grid. A substation equipment group includes at least two substation equipment. When the substation equipment group is in the maintenance state, all equipment in the substation equipment group is in the maintenance state, and the switches associated with the substation equipment group are also in the maintenance state.

[0042] According to the target equipment identification, the target maintenance data of the target substation equipment is retrieved in the equipment maintenance data warehouse, and the maintenance status of the target substation equipment is determined according to the target maintenance data. The maintenance status includes maintenance and non-maintenance. When the equipment is in maintenance status, the tripping information is not considered to be fault tripping information. If it is not in maintenance status, it is necessary to further determine whether the tripping information is caused by normal switching and changes in the operation mode of the power grid.

[0043] S140. When the maintenance state is a non-maintenance state, the target operation state data of the target substation equipment is obtained in the equipment operation state data warehouse according to the target equipment identifier, and whether the tripping information is fault tripping information is determined according to the target operation state data.

[0044] The equipment operation status data warehouse includes the officially operated substation equipment group, that is, the normal operation status of each substation equipment in the equipment bay, and the equipment bay may include the incoming line bay, the outgoing line bay, the bus bay, and the main transformer bay, etc. This embodiment is not limited.

[0045] The target operation status data is used to exclude tripping caused by normal switching operation of substation operators or adjustment of grid operation mode by dispatchers, mainly including the switch status of associated switches of substation equipment under normal operation or adjustment of grid operation mode by dispatchers. For each substation, the name, number and status of the switch associated with the substation are recorded, and bound to the target device identification of the substation, so as to obtain the target operation status data of the switch associated with the target substation in the equipment operation status data warehouse through the target device identification. If the switch status in the target operation status data is different from the trip information, the trip information is fault trip information.

[0046] The equipment operation status data warehouse is initially manually compiled with equipment information and switch status for each interval of the power grid. Later, it is automatically updated based on the switching operation plan information of the maintenance and repair management module of the power grid management platform and the content information of the dispatching operation ticket of the dispatching area on the day. The day is the date when the tripping information is obtained.

[0047] S150: When the tripping information is fault tripping information, obtain fault diagnosis data of the target substation according to the target device identifier, and generate a tripping fault report according to the fault diagnosis data.

[0048] In the case where the tripping information is fault tripping information, the fault diagnosis data of the target substation equipment is obtained in a preset equipment monitoring data warehouse according to the target equipment identification, and a tripping fault report is generated according to the fault diagnosis data.

[0049] Fault diagnosis data may include working status diagnosis data, operation and maintenance status diagnosis data, weather condition diagnosis data, and data collected by at least one smart device.

[0050] The technical solution of this embodiment, by obtaining the switch state change information of the substation equipment in the substation when the substation alarm information of the substation is obtained; when the switch state change information is tripping information, the target device identification of the target substation equipment associated with the tripping information is obtained; according to the target device identification, the target maintenance data of the target substation equipment is obtained in the equipment maintenance data warehouse, and the maintenance state of the target substation equipment is judged according to the target maintenance data; when the maintenance state is a non-maintenance state, the target operation state data of the target substation equipment is obtained in the equipment operation state data warehouse according to the target device identification, and whether the tripping information is a fault tripping information is judged according to the target operation state data; when the tripping information is a fault tripping information, the fault diagnosis data of the target substation equipment is obtained according to the target device identification, and a tripping fault report is generated according to the fault diagnosis data. The technical solution of the embodiment of the present invention solves the problem that the current tripping fault analysis completely relies on manual inefficiency, and can perform tripping fault analysis through automation, quickly and accurately judge whether the tripping is a fault tripping and warn, improve the response speed of fault processing, and ensure the safety and stable operation of the power grid.

[0051] Figure 2 A flowchart of a substation trip analysis method provided in an embodiment of the present invention, this embodiment and the substation trip analysis method in the above embodiment belong to the same inventive concept, and further describes the process of fault trip information judgment. The method can be executed by a substation trip analysis device, which can be implemented by software and / or hardware and integrated into a computer device with application development function.

[0052] like Figure 2 As shown, the substation tripping analysis method of this embodiment includes the following steps:

[0053] S210. When the substation alarm information of the substation is obtained, the switch state change information of the substation equipment in the substation is obtained.

[0054] S220. When the switch state change information is trip information, obtain a target device identifier of a target substation associated with the trip information.

[0055] S230. Obtain target maintenance data of the target substation equipment in the equipment maintenance data warehouse according to the target equipment identifier, and determine the maintenance status of the target substation equipment according to the target maintenance data.

[0057] S250. Determine a target switch state of the target substation according to the on-site operation record information and remote dispatch control instruction information associated with the target substation in the target operation state data.

[0058] The on-site operation record information may be the closing and opening records of the switches associated with the target substation in the on-site operation records such as the work ticket and the operation ticket. For example, if the information recorded in the work ticket is that the closing state changes to the opening state, the target switch state of the target substation is the opening state.

[0059] S260, determining whether the trip information is the same as the target switch state, and if not, determining that the trip information is fault trip information.

[0060] If the target switch state is open, the trip information is the same as the target switch state, otherwise they are different, that is, if the target switch state is closed, the trip information is determined to be fault trip information.

[0061] S270: When the tripping information is fault tripping information, obtain fault diagnosis data of the target substation according to the target device identifier, and generate a tripping fault report according to the fault diagnosis data.

[0062] The technical solution of this embodiment is to obtain the switch state change information of the substation equipment in the substation when the substation alarm information of the substation is obtained; when the switch state change information is tripping information, obtain the target equipment identification of the target substation equipment associated with the tripping information; obtain the target maintenance data of the target substation equipment in the equipment maintenance data warehouse according to the target equipment identification, and judge the maintenance state of the target substation equipment according to the target maintenance data; when the maintenance state is a non-maintenance state, obtain the target operation state data of the target substation equipment in the equipment operation state data warehouse according to the target equipment identification; determine the target switch state of the target substation equipment according to the on-site operation record information and remote dispatch control instruction information associated with the target substation equipment in the target operation state data; judge whether the tripping information is the same as the target switch state, and if not, determine that the tripping information is fault tripping information; when the tripping information is fault tripping information, obtain the fault diagnosis data of the target substation equipment according to the target equipment identification, and generate a tripping fault report according to the fault diagnosis data. The technical solution of the embodiment of the present invention solves the problem that the current tripping fault analysis relies entirely on manual labor and has low efficiency. The tripping fault analysis can be performed automatically, and it can quickly and accurately determine whether the tripping is a fault tripping and issue an early warning based on maintenance information and normal operating switch status, thereby improving the response speed of fault handling and ensuring the safe and stable operation of the power grid.

[0063] Figure 3 A flowchart of a substation trip analysis method provided in an embodiment of the present invention, this embodiment and the substation trip analysis method in the above embodiment belong to the same inventive concept, and further describes the process of obtaining fault diagnosis data. The method can be executed by a substation trip analysis device, which can be implemented by software and / or hardware and integrated into a computer device with application development function.

[0064] like Figure 3 As shown, the substation tripping analysis method of this embodiment includes the following steps:

[0065] S310. When the substation alarm information of the substation is obtained, the switch state change information of the substation equipment in the substation is obtained.

[0066] S320: When the switch state change information is trip information, obtain a target device identifier of a target substation associated with the trip information.

[0067] S330. Obtain target maintenance data of the target substation equipment in the equipment maintenance data warehouse according to the target equipment identifier, and determine the maintenance status of the target substation equipment according to the target maintenance data.

[0068] S340. When the maintenance state is a non-maintenance state, the target operation state data of the target substation equipment is obtained in the equipment operation state data warehouse according to the target equipment identifier, and whether the tripping information is fault tripping information is determined according to the target operation state data.

[0069] S350: When the tripping information is fault tripping information, first diagnostic data of the target substation equipment is obtained in a power grid real-time data monitoring data warehouse according to the target equipment identifier.

[0070] The data monitoring data warehouse includes working status data, operation and maintenance status data and weather condition data of the area associated with the target substation equipment obtained through real-time monitoring. The working status data, operation and maintenance status data and weather condition data of the area associated with the target substation equipment are used as the first diagnostic data, that is, the first diagnostic data includes working status diagnostic data, operation and maintenance status diagnostic data and weather condition diagnostic data of the area associated with the target substation equipment.

[0071] The working status diagnostic data may include SOE (Sequence of Events, time sequence record), such as the event sequence record of protection action and switch tripping, COS (Change of State), such as the closing and opening status of the switch, interval light signs, load data, protection information and intelligent recording data, etc.

[0072] Obtain weather condition data for each key focus area from the local meteorological bureau or power grid meteorological service system. Weather condition data includes weather information and lightning location information. The key focus area is the area where all substations are located and the power grid equipment and facility area of ​​the transmission channel corridor outside the station, that is, the main power transmission and transformation network of the power grid. Weather condition diagnosis data is the weather condition data of the area associated with the target substation equipment.

[0073] In an optional implementation process, the process of obtaining operation and maintenance status diagnostic data can be to obtain at least one operation and maintenance record data associated with the target device identifier based on the target device identifier, and use the operation and maintenance record data as operation and maintenance status diagnostic data; wherein the operation and maintenance record data includes work ticket data, operation ticket data, defect management data and maintenance and repair management data.

[0074] The operation and maintenance status data of the target substation equipment can be obtained in the work ticket management, operation ticket management, defect management, maintenance and repair management, power grid risk, equipment ledger and other modules, and updated in real time to the substation equipment operation and maintenance data warehouse. The operation and maintenance status data can include the work ticket carried out in the station on the same day, namely the work ticket data, the operation ticket for the switching operation on the same day, namely the operation ticket data, historical defect conditions, namely the defect management data, maintenance and repair management data such as patrol maintenance records, N-1 power grid risks and basic information data, etc.

[0075] At least one type of operation and maintenance record data associated with the target device identification is retrieved from the substation equipment operation and maintenance data warehouse according to the target device identification.

[0076] S360. Obtain second diagnostic data of the target substation equipment in the intelligent inspection data warehouse according to the target equipment identifier.

[0077] The second diagnostic data includes collected data of at least one intelligent device associated with the target substation. The at least one intelligent device may include a drone, a robot, and a camera. The camera may include a camera inside the substation and a camera outside the substation. The collected data may include temperature measurement data and image data. The collected data of at least one intelligent device associated with the target substation may be the collected data of a preset time period associated with the acquisition moment or determination moment of the fault tripping information of the target substation. For example, for a camera, the preset time period associated with the acquisition moment may be image data 30 seconds before the acquisition moment and 30 seconds after the acquisition moment. For drones and robots, it may be that after the tripping information is determined to be the fault tripping information, the fault tripping information automatically triggers the patrol and / or temperature measurement behavior of the drone and robot, and obtains the collected image or temperature data of the patrol and / or temperature measurement behavior of the preset time.

[0078] In an optional embodiment, the second diagnostic data of the target substation is obtained in the intelligent inspection data warehouse according to the target device identification, and the target device ledger information of the target substation and the target device group ledger information of the target device group to which the target substation is located are obtained according to the target device identification; the target inspection point of at least one intelligent device associated with the target substation is obtained according to the target device ledger information and / or the target device group ledger information; the target inspection data collected by the intelligent device at the target inspection point is obtained in the intelligent inspection data warehouse, and the target inspection data is used as the second diagnostic data of the target substation, and the target inspection data includes temperature and / or image information.

[0079] The target inspection point of at least one intelligent device associated with the target substation may be a target inspection point associated with the target substation or with the ledger information of the target device group to which the target substation is located.

[0080] For example, the names, numbers and other ledger information of all substation equipment and off-site transmission towers are recorded, the identification and ledger of the substation equipment are bound according to the interval where they are located, that is, the target equipment group, the outgoing line interval ledger is bound to the off-site transmission tower, and the inspection points of cameras, drones and indoor and outdoor robots are bound to the ledger information of the transmission and transformation equipment. This makes it convenient for the system to index the inspection points of the corresponding smart terminals according to the name and number of the equipment to be inspected, and carry out special inspections of a single device or the interval where it is located, and to quickly obtain the video playback of the off-site transmission channel associated with the equipment to be inspected.

[0081] The power transmission and transformation cameras connected to the system are subject to network debugging, preset position acceptance and compilation management. The preset positions are bound to the substation equipment inventory, and the outgoing line interval inventory is bound to the transmission tower outside the station. The transmission channel cameras support video playback.

[0082] Carry out 3D real-life modeling of the substation, plan, split and manage the routes of the drones (or hangars) connected to the system. The drone routes are manually planned in the 3D real-life model of the substation, and the inspection points are bound to the substation equipment ledger. It supports route splitting (i.e. executing some inspection points of a route) and risk point verification, which automatically calculates the closest distance between the route path and the obstacles in the 3D real-life model, so as to determine whether the inspection is safe.

[0083] The substation's indoor and outdoor areas, i.e., outdoor high-voltage sites and indoor equipment rooms, are modeled using 2D radar and the inspection points of indoor and outdoor robots connected to the system are planned, connected, and managed. The indoor and outdoor robot inspection points are located by manually controlled robots and marked in the 2D radar model. The inspection points are bound to the substation equipment ledger, and support manual connection of inspection points into inspection routes.

[0084] The data collected by each smart device is stored in the smart inspection data warehouse, and the target inspection data collected by the smart device at the target inspection point is determined by retrieving the target device ledger information and / or the target device group ledger information, as well as the association between the target device ledger information and / or the target device group ledger information and the target inspection point.

[0085] In an optional embodiment, when the target equipment group is an equipment group for transmitting electric energy outside the substation, the target inspection point of at least one intelligent device associated with the target substation equipment is obtained based on the target equipment group ledger information, which may be the ledger information of the electric pole tower outside the substation associated with the target equipment group; and the camera point information associated with the target equipment group is obtained based on the ledger information of the electric pole tower outside the substation.

[0086] The target device group for transmitting electric energy outside the substation can be the outgoing line interval. The outgoing line interval ledger is bound to the electric pole tower outside the substation. According to the ledger information of the electric pole tower outside the substation, the camera point information associated with the target device group can be retrieved.

[0087] S370. Generate a tripping fault report according to the fault diagnosis data.

[0088] A trip fault report is generated based on the fault diagnosis data, and the trip fault report is sent to the target associated account based on the association between the target substation equipment's ledger information and the user account. The user of the target associated account can perform fault analysis based on the trip fault report to speed up fault handling.

[0089] The technical solution of this embodiment is to obtain the switch state change information of the substation equipment in the substation when the substation alarm information of the substation is obtained; when the switch state change information is tripping information, obtain the target device identification of the target substation equipment associated with the tripping information; obtain the target maintenance data of the target substation equipment in the equipment maintenance data warehouse according to the target device identification, and judge the maintenance state of the target substation equipment according to the target maintenance data; when the maintenance state is a non-maintenance state, obtain the target operation state data of the target substation equipment in the equipment operation state data warehouse according to the target device identification, and judge whether the tripping information is fault tripping information according to the target operation state data; when the tripping information is fault tripping information, obtain the first diagnostic data of the target substation equipment in the power grid real-time data monitoring data warehouse according to the target device identification, the first diagnostic data including working state diagnostic data, operation and maintenance state diagnostic data and weather condition diagnostic data of the area associated with the target substation equipment; obtain the second diagnostic data of the target substation equipment in the intelligent inspection data warehouse according to the target device identification, the second diagnostic data including the collection data of at least one intelligent device associated with the target substation equipment; generate a tripping fault report according to the fault diagnostic data. The technical solution of the embodiment of the present invention solves the problem that the current tripping fault analysis relies entirely on manual labor and has low efficiency. The tripping fault analysis can be performed automatically to quickly and accurately determine whether the tripping is a fault tripping, and obtain data including real-time monitoring status, maintenance, weather data and smart device collection to generate reports for early warning, which is convenient for staff to perform fault analysis based on the early warning information, improve the response speed of fault handling, and ensure the safe and stable operation of the power grid.

[0090] like Figure 4 As shown, in a specific substation tripping analysis method, real-time monitoring data of power grid operation, extreme weather data of key focus areas, and operation and maintenance data of tripping equipment are obtained through the equipment data acquisition module to assist in online monitoring and fault analysis of substation tripping.

[0091] The equipment data acquisition module includes the power grid operation data acquisition submodule, the weather data acquisition submodule and the substation equipment operation and maintenance data acquisition submodule. The power grid operation data acquisition submodule acquires the real-time monitoring data (including SOE, COS, interval light signs, load data, protection information, intelligent recording, etc.) of the power grid (excluding the distribution network) from the dispatching data network.

[0092] The weather data acquisition submodule obtains weather information and lightning location information of key focus areas from the local meteorological bureau or power grid meteorological service system. Definition of key focus areas: the areas where all substations are located and the power grid equipment and facility areas of the transmission corridors outside the substations, that is, the main power transmission and transformation network of the power grid.

[0093] The submodule for acquiring operation and maintenance data of substation equipment obtains the work tickets carried out on the same day in the station related to the tripping equipment, the operation tickets for the same day's switching operations, historical defects, inspection and maintenance records, N-1 power grid risks, basic information data, etc. from the work ticket management, operation ticket management, defect management, maintenance and repair management, power grid risk, equipment ledger and other modules of the power grid management platform.

[0094] By running the maintenance pool module, the information on the current ongoing substation equipment maintenance, equipment status, and planned grid mode adjustment work is automatically recorded and updated, thereby shielding the substation equipment tripping monitoring and analysis system from false alarms caused by the corresponding switch position change (or tripping).

[0095] The operation and maintenance pool module includes the operation pool submodule and the maintenance pool submodule. The operation pool submodule contains the normal operation status of all equipment intervals that have been put into formal operation, and is used to eliminate the equipment switch position change (or tripping) alarm caused by the normal switching operation of the substation operator or the dispatcher's adjustment of the power grid operation mode. Each equipment interval records the name, number and status of the switch and the knife switches on both sides, and associates and binds them together. In the early stage of the operation pool submodule, the equipment information and operation status of each interval of the power grid are manually compiled. In the later stage, according to the switching operation plan information of the maintenance and overhaul management module of the power grid management platform and the content information of the dispatching operation ticket of the day in the dispatching area, the operation pool equipment status is automatically updated and the corresponding switch position change (or tripping) alarm is shielded.

[0096] The maintenance pool module contains the maintenance information of the substation equipment currently in progress in the power grid, and is used to eliminate the equipment switch position change (or tripping) alarm caused by equipment maintenance or protection inspection. The maintenance information of the substation equipment is packaged and obtained from the dispatching area through the firewall to obtain the maintenance work order, which contains the name, number and status of the maintenance equipment. The creation and update of the maintenance pool module are realized through automatic fuzzy retrieval of the name, number and status of the maintenance switch (or knife switch, interval) in the maintenance work order, and the status of the maintenance work order (whether it has been terminated).

[0097] The equipment tripping judgment module determines whether the equipment has tripped due to a fault based on the data of the power grid operation data acquisition submodule and the operation and maintenance pool module of the equipment data acquisition module.

[0098] When the power grid operation data acquisition submodule captures the substation protection general alarm information and the switch position change information within the station, the system automatically starts the equipment tripping judgment module and calls the data of the operation and maintenance pool module to eliminate the switch position change (or tripping) caused by the current substation equipment maintenance and equipment status, and planned adjustment of the power grid mode, so as to determine whether there is a fault tripping of the equipment.

[0099] The tripping analysis and alarm module collects equipment information, generates tripping reports, and displays and pushes alarms after determining that the substation equipment has tripped due to a fault. It also supports functions such as historical alarm storage, query, and playback.

[0100] When the equipment trip judgment module determines that the substation equipment has tripped due to a fault, the system automatically starts the trip analysis and alarm module, queries the information data of each submodule of the equipment data acquisition module according to the name and number of the faulty equipment, obtains the 1-minute visible light video of the corresponding substation inside and outside the smart terminal special patrol module before and after the trip, and sends the patrol task to the smart terminal special patrol module to carry out the patrol and temperature measurement of the faulty equipment interval to assist in the analysis of the cause of the trip. Finally, the trip briefing is generated by combining the information, pictures, and files returned by the equipment data acquisition module and the smart terminal special patrol module, and is pushed to the person in charge of the relevant equipment through AI voice calls or intranet text messages, reminding them to log in to the system to view and confirm the specific alarm.

[0101] Through the smart terminal special patrol module, according to the special patrol tasks and command information issued by the tripping analysis and alarm module, the corresponding smart terminal is dispatched to carry out patrol and temperature measurement of the interval where the faulty equipment is located, and obtain the pre- and post-tripping videos of the cameras inside and outside the relevant substation to assist in the fault analysis of the substation equipment tripping.

[0102] After receiving the faulty equipment interval inspection task instruction issued by the tripping analysis and alarm module, the intelligent terminal special inspection and temperature measurement module indexes the relevant inspection points of intelligent terminals such as cameras, drones, and indoor and outdoor robots according to the name and number of the faulty equipment, and dispatches intelligent terminals to inspect and measure the temperature of the interval where the faulty equipment is located, and finally returns the visible light and infrared photos to the tripping analysis and alarm module. Among them, the intelligent terminals include cameras, drones, indoor and outdoor robots in the substation, and cameras of the power transmission channel outside the substation.

[0103] The smart terminal special patrol and temperature measurement module includes a power transmission and transformation equipment inventory management sub-module, a camera preset position management sub-module, a drone special patrol line management sub-module, and an indoor and outdoor robot patrol point management sub-module.

[0104] like Figure 5 As shown in the figure, the "grid operation data acquisition submodule" of the "equipment data acquisition module" packages and obtains the real-time monitoring data of the power grid (excluding the distribution network) (including SOE, COS, interval light signs, load data, protection information, intelligent recording, etc.) from the dispatching area network through the firewall every 1 minute on average, and captures the total alarm information of the substation protection and the switch position change information in the station.

[0105] If the "grid operation data acquisition submodule" simultaneously captures the protection general alarm information and the station switch position change information of the same substation, the "grid operation data acquisition submodule" will send the captured substation protection general alarm information and the station switch position change information to the "equipment tripping judgment module", and the "equipment tripping judgment module" will query the data of the "operation and maintenance pool module" according to the name and number of the position change switch.

[0106] The "operation and maintenance pool module" sends the normal operation status of the position change switch and related maintenance work information to the "equipment tripping judgment module" to eliminate the switch position change (or tripping) alarms caused by the current substation equipment maintenance and equipment status, and planned adjustment of the power grid mode, so as to determine whether there is a fault tripping of the equipment.

[0107] If the "Equipment Tripping Judgment Module" does not find any substation equipment maintenance and planned adjustment of equipment status and grid mode for the position switch, it is judged that the position switch has tripped due to a fault. The "Equipment Tripping Judgment Module" sends the name and number of the position switch to the "Trip Analysis and Alarm Module". The "Trip Analysis and Alarm Module" queries the "Grid Operation Data Acquisition Submodule" of the "Equipment Data Acquisition Module" for monitoring data when the faulty equipment trips based on the name and number of the faulty equipment, queries the "Weather Data Acquisition Submodule" for weather information and lightning location information when the faulty equipment trips in the area where the faulty equipment is located, and queries the "Substation Equipment Operation and Maintenance Data Acquisition Submodule" for work tickets carried out in the station on the day related to the faulty equipment, operation tickets for the day's switching operations, historical defects, inspection and maintenance records, N-1 grid risks, basic information data, etc.

[0108] The "tripping analysis and alarm module" queries the "power transmission and transformation equipment inventory management submodule" of the "intelligent terminal special patrol module" for the interval inventory information of the faulty equipment according to the name and number of the faulty equipment (if it is an outgoing line interval, the inventory information of the transmission tower outside the station is queried at the same time) and the bound intelligent terminal inspection point information (if it is an outgoing line interval, the inspection point includes the camera preset position of the transmission tower outside the station), and retrieves the visible light video of the preset positions of the cameras inside and outside the substation bound to the faulty equipment 1 minute before and after the tripping. At the same time, the inspection points of the drone and indoor and outdoor robots are sent to the "drone special patrol line management submodule" and "indoor and outdoor robot patrol point management submodule" respectively to carry out post-tripping inspections and temperature measurement of the faulty equipment interval.

[0109] The "tripping analysis and alarm module" combines the information, pictures, files and other data returned by the "equipment data acquisition module" and the "intelligent terminal special patrol module" to generate a tripping briefing for the faulty equipment, which is pushed to the person responsible for the relevant equipment through AI voice calls or intranet text messages, reminding them to log in to the system to view and confirm the specific alarm.
