Description

Technical Field

[0001] The present application relates to the technical field of JP cabinet fault warning, and particularly relates to a JP cabinet fault warning method, device, equipment and storage medium. Background Art

[0002] As a low-voltage power distribution device often used in a power distribution scenario, in practical applications, a JP cabinet (Junction and Protection Cabinet) usually has real-time load adjustment due to power distribution requirements. For example, adjusting the power distribution load according to peak-valley electricity prices, supplying factory equipment or medical equipment according to actual power demands, etc. However, there are indeed some potential safety hazards in this process.

[0003] For example, due to the frequent adjustment of the power distribution load of the JP cabinet, the heat generated by its internal electrical components may cause the cabinet temperature to be too high under high load conditions, thus affecting the normal operation of electrical equipment. If there are problems such as poor electrical connections and aging of insulating materials inside the JP cabinet, it may lead to a short circuit and then cause a fire.

[0004] In practical applications, relevant personnel will be configured to perform regular operation and maintenance on the JP cabinet. However, the same person needs to manage a relatively large number of JP cabinets at the same time, and since the specific actual load of the JP cabinet often changes at different time periods, it results in the relevant personnel being unable to timely discover the abnormal risks during the operation of the JP cabinet, thus causing economic losses and other situations to the JP cabinet.

Obviously, for those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

The realization of the purpose of the present application, functional characteristics and advantages will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0020] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] Refer to Figure 1 , Figure 1 It is a schematic flowchart of the first embodiment of the JP cabinet fault warning method of the present application.

[0022] In the first embodiment, the JP cabinet fault warning method includes the following steps: S10. Predict the target operating parameters of the target JP cabinet according to the JP cabinet digital twin model pre-run locally and the adaptive power distribution strategy preset for the target JP cabinet; It should be noted first that the execution subject of this embodiment is the central server, and the central server is used as the data connection between the cloud and multiple terminal JP cabinets. The central server can receive the data of each JP cabinet and perform functions such as collecting, processing, and analyzing the data of each JP cabinet in the central server.

[0023] Among them, a corresponding JP cabinet digital twin model is set on the central server side. Through this JP cabinet digital twin model, the operating effects of multiple JP cabinets (including the same-level and upper and lower power distribution structures) in the same power grid topology can be simulated, and according to this operating effect, the operating parameters of different JP cabinets can be predicted, etc.

[0024] In addition, the central server can serve as a processing terminal for predicting the operating status and fault warning of the JP cabinet. Relevant operation and maintenance personnel can directly monitor it on the central server side, avoiding the need for relevant operation and maintenance personnel to conduct multi-faceted on-site monitoring. With the digital twin model of the JP cabinet, accurate online analysis can be carried out to quickly determine whether there are faults in the JP cabinet and achieve other effects.

[0025] It can be understood that the digital twin model of the JP cabinet refers to an actual digital derivative model that can simulate the JP cabinet whose operating status needs to be monitored. This digital twin model of the JP cabinet includes the actual power grid topology structure, the upper and lower level power distribution structures, the connection status of each JP cabinet in the power grid, the actual hardware configuration parameters of each JP cabinet, the actual maximum load parameters of each JP cabinet in the power grid, etc. It should be noted that the target JP cabinet refers to the JP cabinet that needs to be monitored currently. This JP cabinet refers to any JP cabinet in the digital twin model of the JP cabinet (the actual power grid topology structure that needs to be monitored). Each JP cabinet in the power grid topology structure that needs to be monitored is configured with a corresponding adaptive power distribution strategy. Among them, this adaptive power distribution strategy can adaptively control the circuit connection effect according to the actual power load demand, and adjust the power load configuration by adaptively controlling the closing and opening effects of the circuit breaker.

[0026] Among them, the adaptive power distribution strategy mainly includes a cost control strategy for controlling electricity costs, reducing the maximum load of the JP cabinet, and ensuring the service life of the JP cabinet in this embodiment. This strategy can be adaptively regulated by the microprocessor built in each JP cabinet, and this adaptive power distribution strategy will fine-tune its specific control time, control logic, etc. according to the historical operation requirements in the actual power grid topology structure. Specifically, for example, according to the peak and valley values of the electricity price, during a fixed time period when the electricity price is at the peak value, the maximum power load is reduced.

[0027] It can be understood that through the digital twin model of the JP cabinet and the adaptive power distribution strategy of the target JP cabinet, the adaptive power distribution adjustment plan of the target JP cabinet and the actual load and operating parameters of the target JP cabinet after actual adaptive power distribution adjustment can be simulated in different time periods. Based on this simulation plan, the target operating parameters of the target JP cabinet in the current time period can be predicted.

[0028] It can be understood that the target operating parameters refer to the target reasonable values of the load and operating parameter changes when the target JP cabinet operates according to the adaptive power distribution strategy. For example, when the electricity cost is the lowest in the current time period, according to the adaptive power distribution strategy, the target JP cabinet will tend to increase the power load to provide a high-power distribution output. At this time, the corresponding target operating parameters of the high load can be obtained through simulation.

[0029] In this embodiment, the step of predicting the target operating parameters of the target JP cabinet according to the adaptive power distribution strategy preset for the digital twin model of the JP cabinet pre-run locally and the target JP cabinet includes: Among them, the digital twin model of the JP cabinet includes the first simulated load data during the operation of other JP cabinets adjacent to the target JP cabinet, the second simulated load data during the operation of the superior substation of the target JP cabinet, and the historical load data of the target JP cabinet; according to the first simulated load data, the second simulated load data, the historical load data, and the adaptive power distribution strategy preset for the target JP cabinet, predict the load change trend and the adaptive load optimization result of the target JP cabinet; according to the change trend and the adaptive load optimization result, determine the target operating parameters of the target JP cabinet.

[0030] It should be noted first that in the actual application process of the JP cabinet, in addition to the adaptive adjustment according to the set control conditions such as the adaptive adjustment time or the specific electricity price, etc., it is also necessary to consider the actual dynamic balance adjustment of the JP cabinet in the power grid topology structure. For example, considering the global power change, after the load capacity of any one of the JP cabinets fails and decreases, the load originally borne by it needs to be borne by other adjacent JP cabinets, so that the load dynamic change effect is generated on other adjacent JP cabinets. Therefore, when simulating the target operating parameters of the target JP cabinet, it is necessary to not only consider the hardware parameters during the operation of the target JP cabinet itself and the optimization effect of the adaptive power distribution strategy, but also synchronously consider the global application effect of the target JP cabinet corresponding to the power grid topology structure.

[0031] Therefore, in the digital twin model of the JP cabinet, the simulated load data of each power node will be taken into account. When the target JP cabinet is determined, the first simulated load data of the JP cabinets adjacent to the target JP cabinet and the second simulated load data of the superior substation of the target JP cabinet will be included in the scope of consideration for simulation prediction, and combined with the three kinds of load data of the historical load data of the target JP cabinet, predict the load change trend and the adaptive load optimization result during the actual operation of the target JP cabinet, and determine the target operating parameters of the target JP cabinet based on this.

[0032] Among them, the load change trend refers to the load change trend of the target JP cabinet in the global load change of the power grid topology structure. For example, when the global load change trend decreases as a whole, the load of the target JP cabinet will also decrease. The adaptive load optimization result refers to the optimization result of the adaptive control of the load of the target JP cabinet according to the adaptive power distribution strategy. For example, adjusting the number of power distribution output branches of the JP cabinet, etc.

[0033] In this embodiment, before the step of predicting the target operating parameters of the target JP cabinet according to the adaptive power distribution strategy preset for the digital twin model of the JP cabinet pre-run locally and the target JP cabinet, the method further includes: Determine the power grid topology structure where the target JP cabinet is located, determine the load data of other JP cabinets adjacent to the target JP cabinet and the superior substation in the power grid topology structure, and obtain the historical operating status of the target JP cabinet, where the historical operating status at least includes the factory hardware configuration parameters of the target JP cabinet and the load change data of the target JP cabinet based on minute-level, hour-level, and seasonal levels; generate virtual load data of the JP cabinet in the target scenario according to the power grid topology structure, where the target scenario at least includes a scenario where the temperature and humidity of the JP cabinet operating environment are greater than a preset standard value and a scenario where there are partial equipment failures in the power grid topology structure; construct a digital twin model of the target JP cabinet according to the power grid topology structure, the load change data, the virtual load data, and the historical operating status.

[0034] It should be noted that the digital twin model of the JP cabinet includes multiple JP cabinets with power connection relationships in the same power grid topology structure, power distribution nodes such as the superior substation, etc. When simulating the power load change of any JP inside it, the global change situation of the power environment where the JP cabinet is located needs to be considered. Therefore, when constructing this digital twin model, not only the historical operating status of the target JP cabinet needs to be obtained to construct the digital model of the target JP cabinet, but also the load data of power nodes such as the superior substation in the power grid topology structure where there is a power connection relationship with the JP cabinet needs to be obtained, and the power grid topology structure where the target JP cabinet is located needs to be obtained to limit the distribution of global power nodes during the construction of the digital model, which is beneficial to the accuracy of subsequent simulation of the model.

[0035] It should be noted that the historical operating status in this embodiment includes the factory hardware configuration parameters of the target JP cabinet and the load change data of the target JP cabinet at different time periods. In order to ensure the accuracy of the data, the load change data is classified into three types of data: minute-level, hour-level, and seasonal. Thus, the load change data of the target JP cabinet is quantitatively classified at different time levels from different time dimensions, which helps to accurately capture the situation of the JP cabinet adjusting the power load according to the adaptive power distribution strategy.

[0036] In addition, after obtaining the actual operation data, in order to supplement the extremely negative data of the model, virtual load data in the corresponding target scenario is generated according to the power grid topology. This virtual load data actually refers to the fault data when equipment failures or abnormal loads occur in the power grid topology. The target scenario at least includes a scenario where the temperature and humidity of the JP cabinet operating environment are greater than the preset standard value (in this scenario, the load of the JP cabinet increases but its allocated power output decreases), and when some equipment fails, in order to balance such failures, the load of the adjacent JP cabinets near the faulty equipment increases.

[0037] Furthermore, after determining the power grid topology, load change data, virtual load data, and historical operation status, the digital twin model of the target JP cabinet can be constructed, and at the same time, the connection conditions between the target JP cabinet and adjacent JP cabinets and the corresponding power nodes of the upper-level substation in the power grid topology where it is located can be shown. In this embodiment, after the step of constructing the digital twin model of the target JP cabinet according to the power grid topology, the load change data, the virtual load data, and the historical operation status, the method further includes: Obtain user-defined state space parameters and action space parameters based on the power grid topology; construct a deep learning policy engine according to the state space parameters and action space parameters; and train the deep learning policy engine through the digital twin model of the JP cabinet to obtain an adaptive power distribution strategy.

[0038] It can be understood that the adaptive power distribution strategy refers to configuring the corresponding automatic control adjustment strategy in the JP cabinet according to the actual needs specified by the user. In the actual operation state, electrical components in the JP, such as circuit breakers, are controlled to control the power distribution effect of the JP cabinet. And this adaptive power distribution strategy will generate corresponding control tendencies according to the actual needs of the user. For example, to control the power usage cost, when the electricity price is high, reduce the power usage load, and when the electricity price is low, increase the power usage load, or to ensure the service life of the JP cabinet, balance the power loads of multiple JP cabinets from the global structure of the power grid topology and reduce the maximum power load of a certain JP cabinet.

[0039] Therefore, when formulating the adaptive power distribution strategy, the corresponding state space parameters and action space parameters can be constructed by means of deep reinforcement learning, and the corresponding reward function can be set according to the actual needs of the user, and then cooperate with the digital twin model of the JP cabinet for training to achieve the effect of quickly converging to obtain the adaptive power distribution strategy.

[0040] Among them, it should be noted that in this embodiment, the reward function for controlling power costs is mainly used as an example for elaboration. Specifically, the state space parameters corresponding to the deep reinforcement learning decision engine in this embodiment include, but are not limited to: the real-time load of the JP cabinet, electricity price, weather, equipment status (such as capacitor health), user priority tags (specifically referring to ensuring the usage priority of any power branch, etc.). The action space parameters corresponding to this learning engine include, but are not limited to: branch switch control, reactive power compensation switching, energy storage charge and discharge instructions, and demand response signals.

[0041] Among them, the reward functions that can be set in this embodiment include, but are not limited to: controlling electricity costs, equipment loss costs, and carbon emission costs from an economic perspective; controlling voltage deviation penalties and overload risk penalties from a safety perspective, and weighted deduction of points for the power supply interruption duration to users (such as factories) from a comfort perspective.

[0042] Among them, the training mechanism of this embodiment can be: offline pre-training: based on historical data + digital twin simulation environment to accelerate policy convergence, or online fine-tuning: adapting to real-time scenarios through transfer learning and updating the policy network every 24 hours. It should be noted that the dynamic scheduling algorithm corresponding to the user's custom priority tags mainly refers to elastic weight allocation: for example, critical loads (hospitals, data centers) are assigned fixed weights, and the weights of ordinary loads (charging piles, advertising light boxes) are dynamically adjusted according to electricity prices and grid status. Example: When the grid is in an emergency, the power of the charging pile is automatically reduced (the weight drops from 1.0 to 0.3) to give priority to ensuring the power supply to the operating room.

[0043] In addition, game theory optimization can be set in this embodiment: modeling the multi-JP cabinet coordination problem as a non-cooperative game, with each JP cabinet as an agent, and solving the global optimal strategy through Nash equilibrium.

[0044] S20. Obtain the real-time operation parameters of the target JP cabinet, and compare and analyze the real-time operation parameters with the target operation parameters; S30. Determine whether there is a fault in the target JP cabinet according to the result of the comparison and analysis. If so, output corresponding alarm information according to the result of the comparison and analysis.

[0045] It is understandable that the target operating parameters refer to the operating parameters of the target JP cabinet in the simulated state. However, in the actual power grid topology, when there are changes in the ambient temperature and humidity, or when there are power output or distribution failures in any JP cabinet or other substations in the power grid topology, the operating parameters will change. Therefore, when obtaining the target operating parameters through simulation, it is necessary to obtain the real-time operating parameters of the target JP cabinet, and compare and analyze the real-time operating parameters with the target operating parameters. The corresponding analysis results can be obtained to determine whether there are operating faults, etc. When it is determined that there is an operating fault, according to the results of the comparison and analysis, the corresponding alarm information can be output. For example, if the load data in the real-time operating parameters of the current JP cabinet in the results of the comparison and analysis is much smaller than the target operating parameters, it can be determined that the JP cabinet has not implemented the adjustment mechanism in the adaptive power distribution strategy. Since the alarm information can be output according to the load situation, relevant personnel can be prompted that there is a problem with the load capacity of the JP cabinet.

[0046] In this embodiment, the target operating parameters of the target JP cabinet are predicted according to the digital twin model of the JP cabinet pre-operated locally and the adaptive power distribution strategy preset for the target JP cabinet; the real-time operating parameters of the target JP cabinet are obtained, and the real-time operating parameters are compared and analyzed with the target operating parameters; according to the results of the comparison and analysis, it is determined whether there is a fault in the target JP cabinet. If so, according to the results of the comparison and analysis, the corresponding alarm information is output, that is, through the digital twin model of the JP cabinet preset locally and the adaptive power distribution strategy preset corresponding to the target JJP cabinet, the adaptive adjustment process of the operating parameters of the JP cabinet in the actual application of the adaptive power distribution process is simulated, and through the simulation method of this digital twin model, the target operating parameters of the target JP cabinet in the actual adaptive power distribution adjustment process are predicted. After predicting the target operating parameters, the real-time operating parameters of the JP cabinet can be obtained, and the real-time operating parameters can be compared and analyzed with the target operating parameters, so as to determine whether there is an abnormality in the actual operating parameters of the target JP cabinet, and thereby determine whether the target JP cabinet has achieved the actual adaptive power distribution effect in the adaptive power distribution process, and inversely deduce whether there is a fault in the target JP cabinet. When there is a fault, according to the results of the comparison and analysis, the corresponding alarm information is output, thereby realizing the rapid detection of whether there is a fault in the operating state of the target JP cabinet when the load changes. Therefore, through the above solution, the operating risk of the JP cabinet can be detected in a timely manner and relevant maintenance personnel can be prompted. As Figure 2 shown, based on the first embodiment, the second embodiment of the JP cabinet fault warning method of the present application is proposed. In this embodiment, step S20 specifically includes: S21, obtaining the real-time operating parameters of the JP cabinet; It is understandable that the real-time operation parameters mainly include multi-dimensional index parameters during the operation of the JP cabinet. For example, the input and output power during the operation of the JP cabinet, the connection status of the JP cabinet relay, the connection status of the grounding line of the JP cabinet, the temperature and humidity of the JP cabinet, and other parameters.

[0047] Among them, the real-time operation parameters can be obtained by means of sensors or detectors set in the target JP cabinet.

[0048] S22. Generate a defined range for determining abnormal operation parameters according to the target operation parameters. It should be noted that each parameter in the target operation parameters serves as standard value data, including but not limited to the standard values of temperature and humidity during the operation of the predicted JP cabinet, the input and output power during the operation of the JP cabinet, the grounding current, etc. Thus, by comparing the collected real-time operation parameters with the target operation parameters, it can be determined whether there are abnormal operation parameters during the current operation of the JP cabinet. That is, when there is a mismatch between the numerical values of the corresponding parameters of the real-time operation parameters and the standard values of the corresponding parameters of the target operation parameters, it is determined that an abnormality has occurred.

[0049] Among them, specific matching rules can be set. According to the target operation parameters, a defined range for determining whether there are abnormal operation parameters is set. For example, the value judgment of the defined range is set at percentage values such as 5% and 10% of the upper and lower fluctuations of the target operation parameters to determine the range value centered on the standard value. When the collected data falls within this range value, it is determined that the current operation is normal. If it exceeds this range value, it is determined that the current operation is abnormal.

[0050] Among them, when it is determined that there is an abnormality, taking the abnormal temperature value, normal humidity value, and normal voltage value as examples, the temperature value is defined as an abnormal operation parameter.

[0051] S23. Determine the abnormal operation parameters in the real-time operation parameters according to the defined range, and compare and analyze the abnormal operation parameters with the target operation parameters.

[0052] Among them, it should be further noted that the abnormal operating parameters also include the parameter deviation value between the temperature value and the standard temperature value during the operation of the JP cabinet (the parameter deviation value is obtained by normalizing the result obtained by subtracting the temperature value from the standard value. Since the units of the operating parameters are different, after obtaining different abnormal operating parameters, further normalization processing is required to calculate their parameter deviation values), and the number of abnormalities of the temperature value on the same day. For example, the detection component collects the temperature value of the JP cabinet during operation every hour, and at least 24 temperature values are generated in a day. If the temperature values during 3 collections are all outside the range of the kitchen standard value, the number of abnormalities is recorded as 3 times. At the same time, the information of the number of abnormalities also includes the time corresponding to the number of abnormalities generated.

[0053] In this embodiment, the step of comparing and analyzing the abnormal operating parameters and the target operating parameters includes: According to the target operating parameters, a multi-dimensional comprehensive evaluation is performed on the abnormal operating parameters to obtain an evaluation result; the historical operation record of the target JP cabinet is retrieved, and the evaluation result and the historical operation record are compared and analyzed.

[0054] It can be understood that after determining the target operating parameters and the abnormal operating parameters, a multi-dimensional comprehensive judgment needs to be made on the two. For example, considering the influence of temperature and humidity changes on the line power of the JP cabinet, or considering the influence of abnormal voltage values of multiple lines on the overall power of the JP cabinet, etc.

[0055] It should be noted that the evaluation result mainly evaluates the corresponding influence between multi-dimensional operating parameters and related state parameters, and the data on the functions that the JP cabinet can achieve under abnormal operating parameters.

[0056] It should be noted that in this embodiment, the historical operation record refers to the record generated naturally during the previous operation of the JP cabinet when there is no operation risk.

[0057] In addition, it should be further noted that during the process of comparing the evaluation result with the historical operation record, it includes the comparison of two aspects of data. On the one hand, each operating parameter and related state parameter are compared. For example, the temperature values are directly compared. On the other hand, the cumulative value of the influence values of the multi-dimensional comprehensive evaluation is compared, and the comprehensive comparison of the two aspects is used to determine whether there is a risk in the JP cabinet.

[0058] Among them, in this embodiment, the comparison results of both aspects need to be taken into account, and a corresponding comparison formula needs to be designed. Specifically, it is aX + bY, where X is the deviation of the parameter value comparison result, Y is the deviation between the cumulative values of the influence values, and a and b are coefficients whose sum is 1, and a is greater than b.

[0059] It is understandable that in this embodiment, two comparison schemes will be adopted, and the results of the two comparison schemes will be compared. According to the above formula, the calculation of the comparison result is mainly to compare the evaluation result with the received original data and historical operation records.

[0060] Therefore, when comparing, corresponding synchronous comparison rules are also set, that is, preset synchronous comparison rules. The preset synchronous comparison rules include two points. On the one hand, the time is the same, and on the other hand, the season is the same. Since the temperature and humidity changes in the JP cabinet working parameters will change with time and season, and at the same time, there are differences in the operating loads of JP cabinets at different times and seasons. Therefore, when comparing, taking the current time to be compared as 12:00 noon in summer as an example, data that is also in summer and at 12:00 noon needs to be extracted from the historical operation records as comparison data.

[0061] Among them, the time information corresponding to the evaluation result includes both date information and time information. The date information can lock the specific season, and the time information can find the comparison data at the precise time.

[0062] It is understandable that according to the above, in this embodiment, the comparison results of both aspects need to be taken into account, and a corresponding comparison formula needs to be designed. Specifically, it is aX + bY, where X is the parameter deviation value of the parameter value comparison result (the sum of the differences between multiple data and the corresponding standard values), Y is the deviation between the accumulated values of the influence values (the accumulated value of a single influence value), and a and b are coefficients whose sum is 1, and a is greater than b.

[0063] Specifically, the comparison result can be divided into two results. The first result is that the data deviation value between the evaluation result and the comparison data corresponding to the historical operation data is greater than the preset deviation value, and the second result is that the deviation value between the evaluation result and the comparison data corresponding to the historical operation data is less than the preset deviation value.

[0064] Among them, the preset deviation value can be a value preset by relevant personnel, and this value needs to be set according to the power parameters, temperature and humidity standards, etc. actually applied to the JP cabinet. In this embodiment, it can be set to 5.

[0065] In this embodiment, the step of performing a multi-dimensional comprehensive evaluation on the abnormal operation parameters according to the target operation parameters to obtain an evaluation result includes: Determine the multi-dimensional influence relationship between the target operation parameters and the abnormal operation parameters at the same moment according to the preset influence factors; perform a multi-dimensional comprehensive evaluation on the abnormal operation parameters according to the multi-dimensional influence relationship to obtain an evaluation result.

[0066] It should be noted that the target operating parameters include at least temperature and humidity parameters, power parameters and line conduction parameters, etc. These parameters are mainly the parameters of the JP cabinet during normal operation. After comparative analysis, some parameters in the real-time operating parameters of the JP cabinet will be identified as abnormal operating parameters when the JP cabinet is in an abnormal state.

[0067] In this embodiment, it is necessary to first determine the impact between abnormal operating parameters based on preset impact factors, and assign an impact factor between each two data (for example, the impact between temperature and power, or the situation where temperature increase affects the normal operation of certain electrical components), and based on the impact factor, comprehensively determine the impact value between each two data. The larger the impact value, the greater the abnormal situation.

[0068] The preset influencing factor is a factor of the degree of influence between different parameters pre-specified by relevant personnel.

[0069] The calculation scheme of the influence value is that the working state of the JP cabinet under certain conditions is predetermined by relevant personnel. For example, at a fixed temperature, the output power of the JP cabinet is a corresponding fixed value, and the proportional relationship between the two (the proportional relationship is the influence factor) is fixed. If there is a difference between the proportional relationship between the two parameters actually obtained and the influence factor, then the difference is the influence value.

[0070] Furthermore, after calculating the impact value between every two parameters, the impact values ​​can be accumulated to obtain the final multi-dimensional comprehensive evaluation result. The larger the accumulated value of the impact value, the higher the operational risk represented by the evaluation result.

[0071] This embodiment obtains the real-time operating parameters of the JP cabinet; generates a defined range for determining abnormal operating parameters based on the target operating parameters; determines the abnormal operating parameters in the real-time operating parameters based on the defined range, and compares and analyzes the abnormal operating parameters and the target operating parameters. After determining the parameter range actually used for evaluation, the defined range and the real-time operating parameters can be further compared to ensure the accuracy of the subsequent warning effect.

[0072] In addition, the present application also provides a JP cabinet fault warning device, referring to Figure 4 , the JP cabinet fault warning device comprises: A prediction module 10 is used to predict the target operating parameters of the target JP cabinet according to the locally pre-running digital twin model of the JP cabinet and the adaptive power distribution strategy preset and configured for the target JP cabinet; An acquisition module 20 is used to acquire the real-time operating parameters of the target JP cabinet, and compare and analyze the real-time operating parameters with the target operating parameters; A determination module 30 is configured to determine whether the target JP cabinet has a fault according to the result of the comparative analysis. If a fault exists, corresponding alarm information is output according to the result of the comparative analysis.

[0073] In this embodiment, the target operating parameters of the target JP cabinet are predicted according to the digital twin model of the JP cabinet pre - running locally and the adaptive power distribution strategy preset for the target JP cabinet; the real - time operating parameters of the target JP cabinet are obtained, and the real - time operating parameters and the target operating parameters are compared and analyzed; according to the result of the comparative analysis, it is determined whether the target JP cabinet has a fault. If a fault exists, corresponding alarm information is output according to the result of the comparative analysis. That is, through the digital twin model of the JP cabinet preset locally and the adaptive power distribution strategy preset for the target JJP cabinet, the adaptive adjustment process of the operating parameters of the JP cabinet in the actual application of the adaptive power distribution process is simulated. And through the simulation method of this digital twin model, the target operating parameters of the target JP cabinet in the actual adaptive power distribution adjustment process are predicted. After predicting the target operating parameters, the real - time operating parameters of the JP cabinet can be obtained, and the real - time operating parameters can be compared and analyzed with the target operating parameters, so as to determine whether the actual operating parameters of the target JP cabinet are abnormal, and thereby determine whether the target JP cabinet has achieved the actual adaptive power distribution effect in the adaptive power distribution process, and inversely deduce to determine whether the target JP cabinet has a fault. When a fault exists, corresponding alarm information is output according to the result of the comparative analysis. Furthermore, the operation status of the target JP cabinet when the load changes is quickly detected for faults. Therefore, through the above - mentioned solution, the operation risk of the JP cabinet can be detected in time and relevant operation and maintenance personnel can be prompted.
