[0032] Example 1

[0033] According to an embodiment of the present invention, an embodiment of a fault warning method for a cable line 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.

[0034] Figure 1 is a flow chart of a cable line fault warning method according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0035] Step S101, obtaining operation data of the cable line.

[0036] In the technical solution provided in step S101 of the present invention, the cable line can be used to indicate high-voltage cable lines in tunnels and various underground projects. The operation data of the cable line at least includes the operation environment parameters and electrical parameters of the cable line, wherein the operation environment parameters of the cable line may include temperature, humidity, etc., and the electrical parameters of the cable line may include current and voltage.

[0037] In this embodiment, a variety of sensors are deployed at key locations of the cable line, including but not limited to: temperature sensors, humidity sensors, vibration sensors, current sensors, voltage sensors, etc. These sensors can comprehensively monitor the operating environment and electrical parameters of the cable line, and collect the operating environment parameters and electrical parameters of the cable line. Among them, the sensors need to have high precision and high reliability, be able to adapt to the complex working environment of the cable line, and ensure the accuracy and real-time nature of the data.

[0038] Step S102: synchronously input the operation data into the digital twin model, and control the digital twin model to operate according to the operation data.

[0039] In the technical solution provided in the above step S102 of the present invention, the digital twin model is obtained by modeling the cable line in advance according to the digital twin technology. The digital twin model, as a physical entity mirror image of the cable line, can reflect the operating status of the cable line in real time.

[0040] In this embodiment, after the operation data is acquired through step S101, the operation data can be synchronously input into the digital twin model, and the digital twin model can operate according to the operation data to realize data sharing between the cable line and the digital twin model, so that the digital twin model can reflect the operation status of the cable line in real time.

[0041] Optionally, since there may be abnormal data or duplicate data in the operating data collected by the sensor, in order to further improve the accuracy of the operating data input into the digital twin model, the operating data can be preprocessed, and then the operating data can be input into the digital twin model, wherein the preprocessing at least includes outlier detection and processing of the operating data to remove noise in the operating data, and data format standardization operations on the operating data after noise removal to improve the accuracy of the operating data input into the digital twin model.

[0042] Step S103, determining the fault prediction result of the cable line according to the operating status of the digital twin model and the simulation result data under the target operating condition corresponding to the cable line operating data.

[0043] In the technical solution provided in the above step S103 of the present invention, the operating status of the digital twin model is at least used to reflect the operating status of the cable line, the simulation result data is used to indicate the normal operating status of the cable line under the target operating conditions, and the fault prediction result is used to indicate whether there is a fault risk in the cable line.

[0044] In this embodiment, the operating data of the cable line under different operating conditions are modeled and simulated in advance to obtain the normal operating status of the cable line under different operating conditions. Based on this, the simulation result data under the target operating condition corresponding to the operating data can be used as a reference to determine the fault prediction result of the cable line.

[0045] For example, the operating state of the digital twin model can be matched with the operating state of the cable line under the corresponding operating conditions obtained by simulation modeling to obtain a matching result, wherein the matching result is used to at least indicate the matching degree between the operating state of the digital twin model and the operating state of the cable line obtained by simulation modeling. If the matching degree is lower than the matching degree threshold, since the operating state of the digital twin model is used to display the operating state of the cable line, in this case, it can be determined that there is a risk of failure in the cable line. Conversely, if the matching degree is higher than the matching degree threshold, it means that the operating state of the cable line displayed by the digital twin model is relatively matched with the operating state of the cable line under the corresponding working conditions displayed by the simulation modeling results. In this case, it can be determined that there is no risk of failure in the cable line.

[0046] Step S104: in response to the fault prediction result indicating that there is a fault risk in the cable line, triggering an alarm message.

[0047] In the technical solution provided in the above step S104 of the present invention, if the fault prediction result determined in step S103 indicates that there is a fault risk in the cable line, an alarm message may be triggered, and the alarm message is used to prompt maintenance of the cable line.

[0048] Optionally, the alarm information can be sent to relevant managers and emergency response teams in real time through preset communication channels to ensure that relevant managers can initiate emergency plans in a timely manner and maintain the cable lines.

[0049] Optionally, the digital twin model and the operating status of the digital twin model can be visualized, and the operation and maintenance personnel can view and adjust the operation and maintenance strategy of the cable line in real time to improve the operation and maintenance efficiency of the cable line.

[0050] In the above steps S101 to S104 of the present application, a digital twin model of the cable line is constructed in advance. Since the digital twin model is a physical entity mirror image of the cable line, it can reflect the operating status of the high-voltage cable line in real time. Based on this, the acquired operating data of the cable line is synchronously input into the digital twin model of the cable line, so as to realize data sharing between the cable line and the digital twin model. Then, by observing the operating status of the digital twin model and combining the normal operating status of the cable line under the operating condition obtained in advance through simulation modeling, the possible fault risks of the cable line can be determined in time, and then, when there is a risk of failure in the cable line, timely alarm is issued, effectively avoiding failures in the cable line and affecting the safety and reliability of the power grid. Through the digital twin technology, comprehensive monitoring and fault warning of the cable line are realized, reducing the impact of cable line failures on the operation of the power grid, and solving the technical problem of untimely fault warning of the cable line due to the inability to monitor the operating status of the cable line in real time.

[0051] The above method of this embodiment is further introduced below.

[0052] As an optional implementation method, step S103 determines the fault prediction result of the cable line according to the operating status of the digital twin model and the simulation result data of the cable line under the target operating conditions corresponding to the operating data, including: determining the operating status of the cable line under the target operating conditions indicated by the simulation data results; determining the fault prediction result of the cable line based on the matching result of the operating status of the digital twin model with the operating status of the cable line under the target operating conditions.

[0053] In this embodiment, the simulation result data is used to represent the operating status of the cable line under different operating conditions calculated through simulation modeling. The simulation result data can be used to represent the operating status of the cable line under different operating conditions under normal circumstances, wherein different operating conditions can be used to indicate different operating environment states.

[0054] Optionally, the simulation result data is used as a reference and then combined with the operating status of the digital twin model to determine whether there is a fault risk in the cable line, thereby obtaining a fault prediction result for the cable line.

[0055] Optionally, the operating condition of the cable line can be determined based on the operating data currently running the digital twin model, and then the simulation result data corresponding to the operating condition can be determined, and then the operating status of the digital twin model can be matched with the normal operating status of the cable line indicated by the simulation result data, and then the fault prediction result of the cable line can be determined based on the matching results of the two.

[0056] In this step, the simulation result data under different operating conditions obtained in advance through simulation modeling are used as a reference, and compared with the operating status of the digital twin model in real time, thereby realizing real-time fault monitoring of the cable line.

[0057] As an optional implementation method, based on the operating status of the digital twin model and the matching result of the operating status of the cable line under the target operating conditions, the fault prediction result of the cable line is determined, including: in response to the matching result indicating that the operating status of the digital twin model and the matching degree of the operating status of the cable line under the target operating conditions is lower than the matching degree threshold, it is determined that there is a fault risk in the cable line.

[0058] In this embodiment, the operating status of the digital twin model is matched in real time with the operating status of the cable line under the target operating conditions indicated by the simulation results. If the matching result indicates that the operating status of the digital twin model matches the operating status of the cable line indicated by the simulation result data, the matching degree is lower than the matching degree threshold. In this case, it means that the operating status of the digital twin model is abnormal. Since the digital twin model is a physical entity mirror of the cable line, the operating status of the digital twin model can reflect the operating status of the cable line in real time. Based on this, when the operating status of the digital twin model is abnormal, it can be determined that there is a fault risk in the cable line.

[0059] Optionally, when there is a risk of failure in the cable line, a fault warning can be triggered, for example, a warning message is issued, wherein the warning message can be sent in real time to relevant managers and emergency response teams through preset communication channels, so as to promptly activate emergency personnel and ensure timely and effective response to the failure risk.

[0060] Optionally, if the matching result indicates the running state of the digital twin model, and the matching degree between the running state of the cable line indicated by the simulation result data is higher than the matching degree threshold, in this case, it means that the running state of the digital twin model is normal, that is, the running state of the cable line is normal, and there is no risk of failure of the cable line. In this case, the running state of the digital twin model can be continuously monitored to issue a timely alarm when the running state of the digital twin model is abnormal.

[0061] As an optional implementation method, the cable line fault warning method also includes: formulating an operation and maintenance strategy for the cable line based on the operating status of the digital twin model; and maintaining the cable line based on the operation and maintenance strategy.

[0062] In this embodiment, since the operating status of the digital twin model can represent the operating status of the cable line, based on this, in the process of real-time monitoring of the operating status of the digital twin model, an operation and maintenance strategy for the cable line can be formulated according to the operating status of the digital twin model, wherein the operation and maintenance strategy can be updated in real time according to the operating status of the digital twin model.

[0063] Optionally, the cable line is maintained according to the operation and maintenance strategy updated in real time to ensure the operational stability and safety of the cable line.

[0064] As an optional implementation manner, the cable line fault warning method also includes: visually displaying the digital twin model and the operating status of the digital twin model.

[0065] In this embodiment, the visualization display is used to indicate that the digital twin model and the operating status of the digital twin model are displayed in the visualization platform, so that the user can view the various operating parameters and environmental indicators of the digital twin model in real time.

[0066] Optionally, since the operating status of the digital twin model can be displayed visually, based on this, the user can adjust the operation and maintenance strategy according to the operating status of the digital twin model displayed on the visualization platform, and then maintain the cable line according to the adjusted operation and maintenance strategy.

[0067] In this step, since the digital twin model and the operating status of the digital twin model can be visualized, based on this, the user can adjust the operation and maintenance strategy of the cable line in real time, so as to promptly discover the operation problems of the cable line and improve the operation and maintenance efficiency and accuracy of the cable line.

[0068] As an optional implementation method, the fault warning method of the cable line also includes: obtaining operating data of the cable line under different operating conditions; based on the operating data under different operating conditions, modeling and simulating the cable line to obtain simulation result data of the cable line under different operating conditions.

[0069] In this embodiment, the operation data of the cable line under different operating conditions can be obtained in advance, wherein the operation data may include but is not limited to: the state of the transmission line, the information fed back by the high-voltage cable line depth monitoring sensor, and the information fed back by the grounding box, etc. After the operation data of the cable line under different operating conditions are obtained, modeling and simulation can be performed based on the operation data of the cable line under different operating conditions to calculate the operation state parameters of the cable line under different operating conditions. The operation state parameters obtained by simulation modeling can be used to characterize the normal operating state of the cable line under different operating conditions. Based on this, the simulation result data obtained by simulation can be used as a reference to determine whether the operation state of the digital twin model under the corresponding conditions is normal, so as to determine whether the cable line has a risk of failure.

[0070] As an optional implementation method, the fault warning method of the cable line also includes: obtaining alarm feedback information of the cable line, wherein the alarm feedback information is used to at least indicate the status monitoring data of the repaired cable line; based on the alarm feedback information, updating the digital twin model of the cable line to obtain an updated digital twin model; based on the updated digital twin model, performing fault monitoring on the cable line.

[0071] In this embodiment, when there is a risk of failure in the cable line, an alarm message can be triggered to remind relevant operation and maintenance personnel to maintain the cable line. After the cable line is maintained, an alarm feedback message can be triggered to indicate that the cable line has been repaired, and the alarm feedback information is used to at least indicate the status monitoring data of the repaired cable line.

[0072] Optionally, since the repaired cable line may have changed in some parameters, based on this, after receiving the alarm feedback information, the digital twin model can be updated based on the alarm feedback information, and then based on the updated digital twin model, the cable line can be monitored for faults to ensure the accuracy of real-time fault warning monitoring of the cable line through the digital twin model.

[0073] In this step, after the cable line fault is repaired based on the alarm information, the digital twin model of the cable line can be iteratively optimized according to the alarm feedback information, so that the iterative digital twin model can accurately feedback the operating status of the cable line, thereby improving the accuracy of the fault warning of the cable line through the digital twin model, and ensuring the long-term stability and reliability of the early warning system.

[0074] As an optional implementation method, the fault warning method of the cable line also includes: obtaining characteristic information of the cable line, wherein the characteristic information includes at least point cloud data of the cable line and status monitoring data of the cable line, and the status monitoring data includes at least line parameters of the cable line, environmental parameters of the cable line, and structural status parameters of the target scene in which the cable line is located; based on the characteristic information, constructing a digital twin model of the cable line.

[0075] In this embodiment, the characteristic information of the cable line at least includes the point cloud data of the cable line and the state monitoring data of the cable line, wherein the point cloud data of the cable line can be obtained by laser scanning, for example, by scanning underground projects such as tunnels with laser scanning equipment, the three-dimensional point cloud data of the underground cable line can be obtained. Among them, the three-dimensional point cloud data of the cable line can be used to at least represent the structural information, spatial layout and connection mode of the cable line. The state monitoring data of the cable line can be obtained by sensors. For example, various sensors can be deployed at key positions of the cable line to obtain the line parameters of the cable line, the environmental parameters of the cable line and the structural state parameters of the target scene where the cable line is located. Among them, the line parameters are at least used to represent the size information of the cable line and the current, voltage, etc. during operation, the environmental parameters of the cable line are at least used to represent the humidity and temperature of the environment where the cable line is located, and the structural state parameters of the target scene where the cable line is located are at least used to represent the structural state of the tunnel where the cable line is located. This is only an illustrative example, and the characteristic information of the cable line can also include other information, which is not exemplified here.

[0076] Optionally, after acquiring the characteristic information of the cable line, a digital twin model of the cable line can be constructed based on the characteristic information of the cable line.

[0077] As an optional implementation, a digital twin model of the cable line is constructed based on the feature information, including: preprocessing the feature information to obtain preprocessed feature information, wherein the preprocessing is used to at least indicate the removal of noise in the feature information and the standardization of the feature information; based on the point cloud data in the preprocessed feature information, a three-dimensional model of the cable line is constructed, wherein the three-dimensional model is used to represent the physical properties and spatial layout of the cable line; and combining the status monitoring data in the preprocessed feature information with the three-dimensional model to construct a digital twin model of the cable line.

[0078] In this embodiment, after acquiring the characteristic information of the cable line, since the data included in the characteristic information of the cable line may contain abnormal values ​​or repeated values, in this case, in order to ensure data quality and to perform accurate data analysis and modeling, the acquired raw data may be preprocessed.

[0079] Optionally, preprocessing may include an outlier detection and processing process, for example, detecting outliers in characteristic data and deleting the detected outliers to remove noise data in the characteristic information. This is only an illustrative example and does not limit the method of removing noise from the characteristic information of the cable line.

[0080] Optionally, after removing noise data from the characteristic information of the cable line, a standardization operation may be performed on the characteristic information after the noise is removed, so as to convert the data into a unified data format to facilitate subsequent data analysis.

[0081] Optionally, after preprocessing the characteristic information of the cable line, a digital twin model of the cable line can be constructed based on the preprocessed characteristic information, wherein the construction of the digital twin model of the cable line includes three-dimensional modeling and twin modeling. Among them, three-dimensional modeling can use three-dimensional modeling technology to process the preprocessed three-dimensional point cloud data to construct a high-precision, high-fidelity three-dimensional model of the cable line and its ancillary settings, wherein the three-dimensional model can truly reflect the physical characteristics and spatial layout of the cable line. Twin modeling can be obtained by combining the three-dimensional model of the cable line with the preprocessed status monitoring data to obtain a digital twin model of the cable line, wherein the digital twin model can truly reflect information such as the operating status and environmental changes of the cable line.

[0082] Optionally, an intuitive monitoring interface is provided for operation and maintenance personnel through a visualization platform, so that real-time monitoring of the operating status of the cable line can be achieved by monitoring the digital twin, and the operation and maintenance personnel can also view the various operating parameters and environmental indicators of the cable line in real time through the monitoring interface.

[0083] Optionally, the digital twin model can be used to diagnose faults in cable lines. For example, since the data of the cable line during its historical operation can characterize the operating status (normal or abnormal) of the cable line, based on this, by combining the data of the cable line during its historical operation and the operating data of the monitored digital twin model, the artificial intelligence algorithm can be used to diagnose faults in the cable line. That is, the abnormal operating status of the cable line can be automatically identified, and possible causes of the fault and solution suggestions can be given.

[0084] Optionally, through the digital twin model and the fault diagnosis results of the cable line, the operation and maintenance strategy of the cable line can be optimized, and a reasonable preventive maintenance plan, fault response mechanism and emergency response plan can be formulated, thereby improving the operation and maintenance efficiency and response speed of the cable line.

[0085] As an optional implementation, the cable line fault warning monitoring method further includes: calculating the line parameters, environmental parameters and structural state parameters of the cable line under different operating conditions and the target scene in which the cable line is located based on modeling and simulation technology.

[0086] In this embodiment, different operating conditions may be composed of different environmental factors or different cable line depth factors, that is, modeling and simulation may be used to calculate the circuit parameters, environmental parameters of the cable line and the structural state parameters of the target scene in which the cable line is located under different cable line depths, or the circuit parameters, environmental parameters and structural state parameters of the cable line in different environments, thereby forming simulation calculation data under different operating conditions.

[0087] Optionally, after obtaining the simulation data, the simulation data can be stored in the computer of the digital twin model. In the visual interface of the digital twin model, the user can call the simulation data in real time and display the results of the retrieved simulation data. The timing of the call depends on the judgment of the real-time monitoring results of the cable line. When the depth of the cable line is found to be abnormal, the user can quickly call the set of simulation data corresponding to the fault and display the results on the digital twin to realize real-time fault diagnosis of the cable line.

[0088] Optionally, by integrating the simulation calculation data of the cable line under different operating conditions obtained by simulation modeling with the digital twin model of the cable line, the accuracy and real-time performance of high-voltage cable operating status monitoring are significantly improved, providing a strong guarantee for the safe operation of power projects.

[0089] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0090] At present, in traditional cable line monitoring, it is usually dependent on manual inspections or timed data collection, which cannot achieve real-time monitoring, resulting in a lack of rapid response in emergencies. There is a technical problem that the cable line fault warning is not timely due to the inability to monitor the operating status of the cable line in real time.

[0091] However, an embodiment of the present invention provides a cable line fault warning method based on digital twin technology. By performing digital twin modeling on the cable line, a digital twin model corresponding to the cable line is obtained, and then the operation data of the cable line is obtained, and data is shared with the digital twin model; the operation status of the cable line is monitored, and combined with the simulation calculation data, the cable line is fault detected, wherein the simulation calculation data is used to indicate the operation status data of the cable line obtained in advance through simulation modeling; when the cable line is monitored to have a fault risk, the warning information can be triggered, wherein the warning information can be sent to relevant management personnel and emergency response teams in real time through a preset communication channel, and the emergency plan is automatically started at the same time, ensuring that the cable line is maintained when the cable line fault does not occur, and ensuring the reliable operation of the cable line. That is, the digital twin technology realizes comprehensive monitoring and fault warning of the cable line, reduces the impact of the cable line fault on the operation of the power grid, and solves the technical problem of untimely fault warning of the cable line caused by the inability to monitor the operation status of the cable line in real time.

[0092] It should be noted that the existing application of digital twin technology in the electrical industry mainly focuses on the display of other environmental factors or substation modeling, and lacks monitoring and application examples for key parameters of the cable body. In order to expand the application of digital twin technology in the electrical industry, the present invention gives full play to the advantages of digital twin technology in data analysis, prediction, maintenance, etc., realizes real-time monitoring of the state of the electrical system, and conducts further analysis and application. By establishing a three-dimensional digital cable corridor model, using cable line multi-factor information monitoring and early warning as an application, and combining digital twin technology to build a three-dimensional digital transmission line high-voltage cable line monitoring visualization platform.

[0093] Next, the cable line fault warning method provided by the embodiment of the present invention is further introduced.

[0094] Figure 2 is a flow chart of a fault warning method for a high-voltage cable line based on digital twin technology according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0095] Step S201, digital twin modeling is performed on multi-factor information of the high-voltage cable line to form a digital twin.

[0096] In this embodiment, the multi-factor information of the high-voltage cable line covers multiple aspects such as the state of the transmission line, the feedback of the high-voltage cable line depth monitoring sensor, and the state of the grounding box. The digital twin is a physical entity mirror image of the high-voltage cable line, which can reflect the operating status of the high-voltage cable line in real time.

[0097] Optionally, based on the core requirements of digital twin technology, the present invention makes full use of the operation history data updated by the physical model and sensors, and realizes the accurate mapping of the whole life cycle of the physical equipment in the virtual environment by integrating complex simulation processes involving multiple disciplines, multiple physical quantities, multiple scales and multiple probabilities. This full life cycle concept covers the complete cycle from the design and development, production and manufacturing, operation and service, maintenance and recycling of physical equipment.

[0098] Optionally, Figure 3 is a schematic diagram of a generation process of a digital twin of a power transmission tunnel according to an embodiment of the present invention, such as Figure 3 As shown in the figure, when generating the digital twin of the transmission tunnel, it is mainly completed through the following process: extracting point cloud tunnel environment attribute data, preprocessing attribute data, collecting spatial data, collecting texture data, and generating the digital twin of the transmission tunnel.

[0099] For example, the present invention has carried out detailed replication modeling work based on the actual scenario of multi-factor information of high-voltage cable lines. The process is subdivided into two main parts: external scene and internal scene. As an example, the internal scene mainly includes key equipment such as transmission lines, depth monitoring sensor devices of high-voltage cable lines, and grounding boxes.

[0100] In the modeling practice, professional software platforms such as 3D modeling software Autodesk 3ds Max and Autodesk Maya and texture drawing software Substance Painter were used. These platforms can perform high-precision digital 3D twin modeling of multi-factor information of high-voltage cable lines based on CAD drawings or obj format model data. In particular, a 1:1 ratio was used to restore the digital twin modeling, thereby generating a digital twin that corresponds one-to-one with the entity. Figure 4 is a schematic diagram of details of generating a digital twin of a power transmission line in a tunnel according to an embodiment of the present invention, such as Figure 4 As shown, the digital twin includes cables, channels, brackets, equipment, etc. in the tunnel. Figure 5 is a schematic diagram of a local twin of a transmission line according to an embodiment of the present invention. Figure 4 and Figure 5 The application effect and value of digital twin technology in high-voltage cable line modeling are intuitively presented.

[0101] Step S202, obtaining real-time high-voltage cable line sensor data of multi-factor information of the high-voltage cable line, and sharing the real-time high-voltage cable line data with the digital twin.

[0102] In this embodiment, a universal submersible level transmitter is used to accurately obtain real-time depth data of multi-factor information of high-voltage cable lines. When local discharge occurs inside the cable, the high-frequency current will propagate along the ground wire to detect the local discharge. The Rogowski coil method is used to sense the high-frequency alternating electromagnetic field generated when the high-frequency current passes through the center of the magnetic core, thereby obtaining high-frequency partial discharge signal data. The temperature sensor is used to measure the operating temperature of the cable and its accessories. The cable will be affected by temperature during operation. The temperature sensor can monitor the cable temperature in real time to ensure that the cable operates within the allowable temperature range.

[0103] Specifically, at the high-voltage cable line multi-factor information monitoring project site, special high-voltage cable line monitoring modules were deployed. These modules can detect and record the depth data of the high-voltage cable line in real time, and then share this data with the digital twin in real time. Figure 6 It is a schematic diagram of feedback of simulation results of a high-voltage cable line affected by multiple factors according to an embodiment of the present invention.

[0104] In this step, not only is comprehensive monitoring of multi-factor information of high-voltage cable lines achieved, but it also ensures that the digital twin can reflect the actual status of the physical line in real time, thus providing a solid data foundation for subsequent data analysis, fault warning and decision support.

[0105] Step S203, modeling and simulating the multi-factor information of the high-voltage cable line, calculating the high-voltage cable line status data of the multi-factor information of the high-voltage cable line under different operating environment states, forming simulation calculation data, and integrating the simulation calculation data with the digital twin as a database.

[0106] In this embodiment, simulation technology is used to comprehensively model and simulate the multi-factor information of the high-voltage cable line. The model can accurately simulate the current characteristics of the high-voltage cable under different operating conditions and depths, and generate a series of high-precision simulation calculation data through algorithm analysis calculation results. This process pays special attention to the types of defects that may occur in high-voltage cables, such as poor contact, cable wear, increased dielectric loss caused by moisture, and material defects. Through meticulous simulation analysis, the impact of these defects on the depth data of the high-voltage cable line is recorded, and strictly compared with the simulation results under normal working conditions.

[0107] Furthermore, the transmission line cable data and high-voltage cable line data under normal operation and typical fault conditions are compared. In this comparison process, the impact of different load conditions and environmental conditions on the depth of the high-voltage cable line is fully considered, and corresponding boundary conditions and fault conditions are set according to common fault types to ensure the comprehensiveness and accuracy of the simulation data.

[0108] In order to give full play to the functions of digital twins, the above-mentioned simulation calculation data is deeply integrated with the digital twin. As a mirror image of a physical entity in a virtual environment, the digital twin can reflect the operating status of the physical entity in real time. However, the digital twins in the prior art are mainly limited to effect display. By integrating simulation calculation data, the present invention enables the digital twin to not only display the 3D model of the high-voltage cable, but also reflect the simulation results under different state conditions in real time, thereby realizing real-time monitoring and early warning of the operating status of the high-voltage cable.

[0109] Optionally, based on historical experience and pre-modeling simulation, a comprehensive modeling of various faults that have occurred in the multi-factor information of the high-voltage cable line is carried out, and at the same time, equipment simulation calculations when there is no fault are carried out as control group data. These simulation calculation data are stored as the data basis in the computer where the digital twin is established. On the digital twin interface, the user can call the above database in real time and display the results of a certain set of data retrieved. The timing of the call depends on the judgment of the real-time monitoring results of the physical entity of the equipment. When an abnormality is found in the depth of the high-voltage cable line on the surface of the physical entity, the user can quickly retrieve the set of simulation calculation data corresponding to the fault from the database and display the results on the digital twin to achieve real-time fault warning and diagnosis.

[0110] In this step, the accuracy and real-time performance of high-voltage cable operation status monitoring are significantly improved through the modeling and simulation of multi-factor information of high-voltage cable lines and the fusion technology of digital twins, providing a strong guarantee for the safe operation of power projects.

[0111] Step S204, monitoring the operating status of the multi-factor information of the high-voltage cable line, and performing fault monitoring and early warning on the multi-factor information of the high-voltage cable line based on the real-time monitoring data and the simulation calculation data.

[0112] In this embodiment, digital twin technology is used to construct a digital twin of multi-factor information of high-voltage cable lines. The digital twin can map and mirror the operating status of physical entities to achieve comprehensive monitoring of multi-factor information of high-voltage cable lines. By matching and comparing real-time monitoring data and simulation calculation data, the operating status of high-voltage cable lines can be accurately judged, and potential faults can be warned based on the comparison results. After the warning information is released, it can be sent to relevant managers and emergency response teams in real time through preset communication channels, and the emergency plan can be automatically started to ensure timely and effective response measures.

[0113] Optionally, Figure 7 is a schematic diagram of a high-voltage cable line multi-factor information monitoring digital platform according to an embodiment of the present invention, such as Figure 7As shown, the digital platform can visualize the status information of high-voltage cable lines, such as the water level value in the tunnel, access control status, temperature, and the content of various gases.

[0114] Furthermore, the real-time monitoring data is compared with the simulation calculation data of the high-voltage cable line under abnormal conditions to more accurately identify faults such as abnormal temperature rise of the high-voltage cable line. This comparison not only improves the accuracy of fault detection, but also helps to take corresponding measures in time to prevent the fault from further expanding.

[0115] Step S205, iteratively optimize the digital twin model according to the warning effect and the actual changes in the high-voltage cable line.

[0116] In this embodiment, iterative optimization of the digital twin model can improve prediction accuracy and ensure the long-term stability and reliability of the early warning system.

In addition, combined with the online monitoring function, the data is organically integrated with the digital twin kernel, further improving the accuracy of status assessment and fault prediction.
