[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] According to an embodiment of the present invention, an embodiment of a processing method for a protection device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of a processing method of a protection device according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, in response to receiving the locking signal sent by the protection device, generating a patrol instruction of the protection device, and sending the patrol instruction to the protection signal master station and the production monitoring system.

[0031] The above-mentioned protection device can be used to monitor the operating status of power equipment in the power system. When an abnormal situation is detected, such as overcurrent, short circuit, overvoltage, loss of pressure or equipment failure, the fault can be isolated by tripping or locking to prevent the fault from expanding and ensure the safe and stable operation of the power grid. The power equipment that can be protected by the protection device can be transformers, lines, generators, etc. The power equipment is not limited here and can be determined as needed. When the protection device detects a serious fault or functional failure, it will automatically lock to prevent erroneous instructions or status from further affecting the safety of power equipment in the power system. After the protection device is locked, it can trigger operations such as automatic reporting of alarm signals, remote inspections, automatic restart attempts, or automatic power outages for maintenance, which can improve the efficiency and accuracy of fault handling, reduce manual intervention, and ensure the continuity and reliability of power system operation.

[0032] The above-mentioned lockout signal can be an emergency signal issued by the protection device when it detects a fault or functional failure. The lockout signal is completed and issued by the self-check mechanism inside the protection device. When the protection device detects that there is a serious fault in itself, the lockout signal can prevent the protection device from performing the protection action, avoiding the false tripping of the faulty device and causing unnecessary power outages. In addition, after the lockout signal is issued, the intelligent operation and maintenance process will be triggered. The operation and maintenance process can be implemented by the security master station, production monitoring system, power grid dispatching automation (Outage Coordination System, referred to as OCS) system, dynamic instruction control platform (Dynamic Instruction Control Platform, referred to as DICP) system, etc.

[0033] The above-mentioned patrol instruction can be a control instruction for checking and maintaining the status of the protection device. The patrol instruction can be issued to the security master station or the production monitoring system to check the protection device. Through the patrol instruction, the fault status of the protection device can be confirmed and the information of the protection device can be collected for subsequent fault handling strategies.

[0034] The above-mentioned security master station is usually deployed in the safety zone I of the power dispatching center to centrally manage and analyze data from the security substation on the substation side. The security master station can collect the telesignaling and telemetry data sent by the protection device on the substation side in real time, and monitor the communication status between the protection device and the security master station. The security master station can also conduct remote inspections of locked protection devices according to inspection instructions, check the working status of the protection devices, collect alarm information, etc. The security master station can report the collected protection device information, such as alarm information, locking status, communication status, etc., to the intelligent operation and maintenance server for further fault handling.

[0035] The above-mentioned production monitoring system is usually deployed in safety zone III for remote monitoring and maintenance of power equipment. In particular, the production monitoring system can dispatch patrol robots to conduct automated patrols and collect real-time status and environmental information of the equipment. The production monitoring system can receive data and images sent back by patrol robots, analyze whether they are operating normally and whether maintenance or repair is required, and then report the patrol results to the intelligent operation and maintenance server. The production monitoring system can also manage automated patrol tasks, including patrol robot scheduling, patrol route planning, patrol task execution and monitoring, etc.

[0036] Security Zone I is usually the area responsible for production control in the power system. Security Zone I may include systems such as power grid dispatching automation system, data acquisition and monitoring system, etc. These systems are used to process real-time data and do not allow unauthorized access.

[0037] Security Zone III is usually located inside the power system and connected to the external network. Security Zone III may include production monitoring systems, information systems, etc. Data transmission from Security Zone I to Security Zone III needs to pass through a forward isolation device, while data transmission from Security Zone III to Security Zone I needs to pass through a reverse isolation device to prevent reverse penetration of information from low security zones to high security zones.

[0038] In an optional embodiment, after receiving the locking signal, the locking signal can be analyzed to obtain locking information, and a patrol instruction can be further generated according to the locking information. Alternatively, the locking signal can be manually analyzed and configured through an interactive interface to obtain a patrol instruction. Alternatively, the locking signal can be analyzed by a server to remotely generate a patrol instruction.

[0039] Furthermore, the patrol instructions can be sent to the Baoxin main station through the firewall. Alternatively, the patrol instructions can be sent to the production monitoring system through the forward and reverse isolation device. Alternatively, the patrol instructions can be sent to the Baoxin main station and the production monitoring system respectively according to the preset allocation rules.

[0040] Step S104, receiving the first inspection result sent by the Baoxin master station and the second inspection result sent by the production monitoring system.

[0041] Among them, the first inspection result is obtained by the Baoxin main station inspecting the protection device, and the second inspection result is obtained by the production monitoring system analyzing the inspection photos. The inspection photos are obtained by the production monitoring system controlling the inspection robot to inspect the protection device. The first inspection result includes: the communication status between the protection device and the intelligent operation and maintenance main station, and the alarm information of the protection device. The second inspection result includes: the operation status of the protection device.

[0042] The above-mentioned first inspection result can be obtained by the protection signal master station by inspecting the protection device based on the inspection instruction. The first inspection result may include but is not limited to: the communication status between the protection device and the intelligent operation and maintenance master station, and the alarm information of the protection device. The first inspection result is not limited here and can be determined as needed. The first inspection result can facilitate remote status monitoring, and can also be used for alarm information analysis, or for checking communication status.

[0043] The above-mentioned second inspection result can be obtained by the production monitoring system analyzing the inspection photos based on the inspection instructions. The inspection photos can be obtained by the production monitoring system controlling the inspection robot to inspect the protection device. The second inspection result may include but is not limited to: the operation status of the protection device. The second inspection result is not limited here and can be determined as needed. The second inspection result can facilitate the confirmation of the on-site conditions and the fault analysis.

[0044] In an optional embodiment, the first inspection result and the second inspection result can be obtained from the data platform. Through the data platform, it is convenient to uniformly manage and call the inspection results. The first inspection result is sent by the Baoxin master station and stored in the data platform, and the second inspection result is sent by the production monitoring system and stored in the data platform.

[0045] In another optional embodiment, the first inspection result and the second inspection result can also be obtained through a message queue mechanism. Using the message queue mechanism, the security master station and the production monitoring system send the first inspection result and the second inspection result to the message queue respectively, so as to read the message from the message queue and further analyze and process the results.

[0046] In another optional embodiment, data can also be shared through blockchain technology. The Baoxin master station and the production monitoring system encrypt the first inspection result and the second inspection result and write them into the blockchain respectively, so that the inspection results can be read through the blockchain node. The distributed ledger characteristics of the blockchain can ensure the immutability and transparency of the data.

[0047] Step S106: Determine whether to process the protection device based on the first inspection result and the second inspection result.

[0048] The above-mentioned processing uses the first inspection result and the second inspection result to analyze whether the protection device has a fault, so that the protection device can be handled in time when a fault occurs. If it is determined that the locking of the protection device is caused by a software fault, a temporary hardware fault or a communication fault, the protection device will be restarted. If it is determined that the locking of the protection device is caused by hardware damage or environmental factors, it can be inspected and repaired. If it is determined that there is a serious fault in the protection device, the faulty protection device can be switched from the operating state to the maintenance state by controlling the primary equipment for troubleshooting and repair. If it is determined that the locking of the protection device is caused by an outdated software version or a configuration problem, the software can be upgraded or the configuration can be adjusted.

[0049] In an optional embodiment, a machine learning or artificial intelligence algorithm can be used to analyze and determine whether to process the protection device. The first inspection result and the second inspection result are input into a trained fault classification model to identify the fault type and severity, thereby determining whether to process the protection device. This can reduce manual intervention and improve the efficiency and accuracy of processing.

[0050] In another optional embodiment, the first inspection result and the second inspection result can be input into an expert system, and the expert system automatically determines whether the protection device needs to be processed and what processing measures to take based on preset rules and knowledge base. This method combines the experience of professionals and the processing power of computers, and can provide more reliable decision support when dealing with complex or rare faults.

[0051] In another optional embodiment, a multi-level warning mechanism can be set up to automatically trigger warning signals of different levels based on the first inspection results and the second inspection results, and determine corresponding handling measures based on the severity and urgency of the fault, while promptly notifying relevant operation and maintenance personnel for repair and processing.

[0052] In an embodiment of the present invention, in response to receiving a locking signal sent by a protection device, a patrol instruction of the protection device is generated, and the patrol instruction is sent to the security main station and the production monitoring system; the first patrol result sent by the security main station and the second patrol result sent by the production monitoring system are received, wherein the first patrol result is obtained by the security main station patrolling the protection device, the second patrol result is obtained by the production monitoring system analyzing the patrol photo, and the patrol photo is obtained by the production monitoring system controlling the patrol robot to patrol the protection device, the first patrol result includes: the communication status between the protection device and the intelligent operation and maintenance main station, the alarm information of the protection device, and the second patrol result includes: the operation status of the protection device; based on the first patrol result and the second patrol result, it is determined whether to process the protection device. It is easy to notice that the automatic locking processing method is adopted, and the patrol instruction is automatically generated after receiving the locking signal to patrol the protection device, which reduces manual intervention, thereby using the first patrol result and the second patrol result to determine that the protection device is processed, and the purpose of timely processing the protection device is achieved, thereby achieving the technical effect of improving the processing efficiency of the protection device, and thus solving the technical problem of cumbersome and inefficient processing flow of the protection device in the prior art.

[0053] Optionally, the protection device is processed based on the first inspection result and the second inspection result, including: in response to the first inspection result that the communication between the protection device and the intelligent operation and maintenance main station is normal and the protection device does not generate an alarm message, and the second inspection result is that the protection device operates normally, determining not to process the protection device; in response to the first inspection result that the communication between the protection device and the intelligent operation and maintenance main station is abnormal, or the protection device generates an alarm message, or the second inspection result is that the protection device operates abnormally, determining to process the protection device.

[0054] This decision-making mechanism based on multi-source information can avoid unnecessary operations, reduce interference with protection devices, and ensure their normal operation.

[0055] In an optional embodiment, the protection device can be processed according to preset rules by the rule engine. The preset rules may include but are not limited to: if the first patrol result is that the communication between the protection device and the intelligent operation and maintenance main station is normal, and the protection device does not generate alarm information, and the second patrol result is that the protection device is operating normally, no processing is performed; if the first patrol result is that the communication between the protection device and the intelligent operation and maintenance main station is abnormal, or the protection device generates alarm information, or the second patrol result is that the protection device is operating abnormally, processing is performed. The preset rules are not limited here and can be determined as needed.

[0056] In another optional embodiment, the state machine can also automatically switch to the current state of the corresponding protection device according to the received first patrol result and the second patrol result, and generate a processing or non-processing instruction based on the current state. The current state may include but is not limited to: communication state, alarm state, and operation state. The current state is not limited here and can be determined as needed.

[0057] In yet another optional embodiment, a decision tree algorithm may be used to determine whether to process the protection device based on the characteristics of the first patrol result and the second patrol result.

[0058] Optionally, the protection device is processed, including: sending a restart instruction to a dynamic instruction control platform system, wherein the restart instruction is used to control the dynamic instruction control platform system to generate a restart operation file, and the restart operation file is used to control the measurement and control device to perform a restart operation on the protection device; in response to receiving a restart completion signal sent by the protection device, the protection device is processed based on the restart completion signal.

[0059] The restart instruction can be used to control the dynamic instruction control platform system to generate a restart operation file. The restart operation file can be used to control the measurement and control device to perform a restart operation on the protection device.

[0060] Through remote restart operations, abnormal states of protection devices caused by software failures or communication anomalies can be quickly restored, which improves the speed of fault recovery. In the operation and maintenance of smart grids, this method can significantly reduce the number of on-site maintenance and reduce operation and maintenance costs.

[0061] The dynamic command control platform system can be used to automatically generate operation tickets, generate operation steps according to the restart instructions, and send them to the OCS system, thereby controlling the measurement and control device to perform restart operations on the protection device. In the power system, the use of the dynamic command control platform system can improve operational efficiency, reduce human errors, and achieve remote and automated control.

[0062] In an optional embodiment, a restart instruction can be sent to the dynamic instruction control platform system by calling an interface, or a restart instruction can be sent through a message queue, or a restart instruction can be sent through a middleware. The protection device sends a restart completion signal after completing the restart so that the protection device can be processed based on the restart completion signal. Optionally, the restart completion signal sent by the protection device can be received by monitoring signals, message queues, or service orchestration engines. Then, the restart completion signal is parsed to evaluate the restart effect, or threshold monitoring is triggered to monitor the operating parameters of the protection device. Alternatively, the corresponding processing operation can also be triggered by a state machine driver.

[0063] Optionally, the protection device is processed based on the restart completion signal, including: receiving a lockout signal detection result of the protection device sent by the dynamic command control platform system, wherein the lockout signal detection result is obtained by the dynamic command control platform system by detecting the lockout signal of the protection device after performing a restart operation on the protection device; in response to the lockout signal detection result being that the lockout signal is in an abnormal state, receiving a defect processing request sent by the power grid dispatching automation system; generating a maintenance processing instruction based on the defect processing request; and processing the protection device based on the maintenance processing instruction.

[0064] The lockout signal detection result can be obtained by the dynamic command control platform system after the protection device is restarted by detecting the lockout signal of the protection device. In the fault handling of the power system, the lockout signal detection result can be used as a key basis for judging whether the protection device has returned to normal. Through automated detection, the accuracy and efficiency of fault judgment are improved. By detecting the lockout signal, the effectiveness of the restart operation can be ensured, avoiding secondary faults caused by improper restart operation.

[0065] In an optional embodiment, the blocking signal detection result may be received through event subscription. Alternatively, the blocking signal detection result may be obtained by calling a service interface.

[0066] Furthermore, when it is determined that the blocking signal detection result is that the blocking signal is in an abnormal state, the workflow automation is triggered to generate a maintenance processing instruction based on the defect processing request after receiving the defect processing request sent by the power grid dispatching automation system, and then process the protection device based on the maintenance processing instruction. Alternatively, through event subscription, when it is determined that the blocking signal detection result is that the blocking signal is in an abnormal state, the defect processing request process is triggered.

[0067] Optionally, the protection device is processed based on the maintenance processing instruction, including: sending the maintenance processing instruction to the dynamic instruction control platform system, wherein the maintenance processing instruction is used to control the dynamic instruction control platform system to generate a maintenance operation file, and the maintenance operation file is used to control the measurement and control device to convert the operating state of the protection device into a maintenance state; receiving the processing result of the protection device sent by the power grid dispatching automation system, wherein the processing result is used to characterize whether the protection device has been successfully maintained, and the processing result is obtained by detecting the maintenance state of the protection device.

[0068] The above maintenance processing instructions can be used to control the dynamic instruction control platform system to generate maintenance operation files, which are used to control the measurement and control device to convert the operating state of the protection device into the maintenance state. And the processing result of the protection device can be determined according to the maintenance state.

[0069] With the help of maintenance processing instructions, the automatic conversion of the protection device status can be realized, providing a safe environment for subsequent troubleshooting and repair. In the maintenance of the power system, the automatic conversion of the protection device status can avoid human operation errors and improve the safety and efficiency of maintenance.

[0070] In an optional embodiment, the maintenance processing instruction can be sent through the application program interface, and the processing result of the protection device sent by the power grid dispatching automation system can be received. Alternatively, the maintenance processing instruction can be received and processed through the message queue, and then the processing result can be sent. Alternatively, a processing flow can be created through the service orchestration engine to send the maintenance processing instruction to the dynamic instruction control platform system, and then the processing result of the protection device sent by the power grid dispatching automation system can be received.

[0071] Optionally, the method further includes: in response to the locking signal detection result being that the locking signal is in a normal state, determining that the processing of the protection device is completed.

[0072] Through the detection results of the blocking signal, it can be ensured that the protection device returns to normal operation after processing, so as to facilitate the normal operation of the subsequent protection device. In the power system, the normal operation of the protection device is the key to ensuring the safety and stability of the power grid. Through automated detection and confirmation, the level of refinement of operation and maintenance management can be improved.

[0073] In an optional embodiment, the locking signal can be continuously detected through an event-driven mechanism, and when the locking signal detection result is confirmed to be in a normal state, it is determined that the processing of the protection device is completed. Alternatively, the locking signal detection result can be fed back to the workflow engine. Alternatively, the service interface can be called to confirm that the locking signal detection result is that the locking signal is in a normal state, thereby completing the processing of the protection device.

[0074] Optionally, the restart operation file and the maintenance operation file both include at least: an operation task and operation steps.

[0075] The above-mentioned restart operation file at least includes: operation tasks and operation steps. The operation file is not limited here and can be determined as needed. The operation task can be to restart the protection device. The operation steps can be the specific links and the order of each link to achieve the restart task, ensuring the clarity and executableness of the restart operation. For example, the restart operation steps may include but are not limited to: disconnecting the power supply, reclosing the power supply, monitoring the restart process, checking the status of the protection device, recording the restart results, etc. The operation steps are not limited here and can be determined as needed.

[0076] The above-mentioned maintenance operation file at least includes: operation tasks and operation steps. The maintenance operation file is not limited here and can be determined as needed. The operation task can be one of the following: switching the protection device from operation to maintenance, checking and reporting the status of the protection device, etc. The operation task is not limited here and can be determined as needed. The operation steps can be the specific links for implementing the maintenance task and the order of each link to ensure the clarity and executable nature of the maintenance operation. For example, when the operation task is to switch the protection device from operation to maintenance, the operation steps may include but are not limited to: confirming the status before the operation, disconnecting the primary equipment, isolating the protection device, setting protective measures, performing maintenance operations, testing the protection device, restoring the operating status of the protection device, and recording the status of the protection device. The operation steps are not limited here and can be determined as needed.

[0077] By restarting the operation file and overhauling the operation file, the accuracy and executability of the operation instructions can be ensured, avoiding misoperation caused by instruction errors. In the power system, the structured design of files is the basis for realizing remote operation and automated operation and maintenance, which can improve the standardization of operations and reduce operational risks.

[0078] In an optional embodiment, the restart operation file and the maintenance operation file can be obtained through manual text records. Alternatively, the restart operation file and the maintenance operation file and their specific contents can be displayed through a control interface. Alternatively, the restart operation file and the maintenance operation file can be generated by a preset configuration rule.

[0080] The power grid dispatching automation system sends the protection device locking signal to the intelligent operation and maintenance server. The intelligent operation and maintenance server sends a patrol instruction to the Baoxin master station. The Baoxin master station patrols the protection device based on the patrol instruction. Then, it determines whether the communication is normal, that is, whether the communication between the Baoxin master station and the protection device is normal. When the communication is normal, the Baoxin master station sends the first patrol result to the operation and maintenance master station, and then the operation and maintenance master station sends the patrol instruction to the production monitoring system; when the communication is abnormal, the operation and maintenance master station sends the patrol instruction to the production monitoring system. Further, the production monitoring system patrols based on the patrol instruction and sends the second patrol result to the operation and maintenance master station. The operation and maintenance master station generates a processing result based on the first patrol result and the second patrol result.

[0081] Then, determine whether the protection device needs to be restarted, and terminate the processing flow if restart is not required. In the case where the protection device needs to be restarted, the operation and maintenance master station sends the restart instruction to the dynamic instruction control platform. The dynamic instruction control platform generates and sends a first operation ticket. Then, the power grid dispatching automation system generates and sends a first operation instruction based on the first operation ticket, so that the measurement and control device performs a restart operation based on the first operation instruction. After the measurement and control device completes the restart of the protection device, it determines whether the locking signal is reset. If so, the process ends. Otherwise, the operation and maintenance master station sends a transfer maintenance instruction to facilitate the transfer maintenance operation, and then the dynamic instruction control platform generates a second operation ticket so that the power grid dispatching automation system receives and executes the second operation ticket. The power grid dispatching automation system sends a second operation instruction, and further, the measurement and control device completes the operation of the primary equipment based on the second operation instruction and ends the process.

[0082] According to another aspect of the present invention, a processing system for a protection device is provided. The processing system is used to execute the message processing method in the above embodiment, and the specific application scenario and preferred embodiment are the same as the above embodiment, which will not be described in detail here.
