[0027] In this embodiment, the circuit design diagram records the connection relationship information, model information, and protection information of each power component. The power components include cables, circuit node components, and circuit non-node components. The protection information includes protection response type and protection level. For example, when the cable's sheath includes an armored sheath, a corrosion-resistant sheath, a waterproof sheath, a high-temperature resistant sheath, a low-temperature resistant sheath, and an anti-ultraviolet sheath, the corresponding technical manual is retrieved according to the cable model to determine the protection level of the cable for each protection response type. The degradation record table is used to record the current abnormal degradation level, environmental degradation level, and cumulative degradation parameters of the power component. The degradation record table has built-in abnormal degradation algorithm, environmental degradation algorithm, and degradation parameter algorithm.

[0028] Specifically, all circuit design drawings of the area to be monitored are obtained to create a regional circuit model, so as to obtain the circuit connection status of each power component in the area to be monitored, facilitate subsequent analysis of the influence between each power component, determine the correspondence between the detection data and each power component, and associate each power component with a degradation record table for recording abnormal degradation level, environmental degradation level and cumulative degradation parameters, so as to facilitate quantitative evaluation of the degree of degradation of each power component.

[0029] Wherein, in step S10, it includes: S11: Obtain all circuit design drawings of the area to be monitored, analyze the circuit connection relationship between different circuit design drawings, and create a regional circuit model.

[0030] Specifically, all circuit design drawings in the area to be monitored are obtained, and the circuit connection relationship between different circuit design drawings is analyzed, so as to create a regional circuit model to simulate the overall circuit network operation status of the area to be monitored.

[0031] S12: Based on the model information of each power component in the regional circuit model, the corresponding degradation record table is associated, and the protection information of each power component is input into the degradation record table.

[0032] In this embodiment, the degradation record table records the performance parameters corresponding to the power components.

[0033] Specifically, based on the model matching of each power component in the regional circuit model, a corresponding degradation record table is prepared, wherein the degradation record table records the performance parameters corresponding to the power components. The protection information of each power component is input into the corresponding degradation record table to facilitate the subsequent evaluation of the cumulative degradation parameters based on the protection information and performance parameters of each power component.

[0034] Among them, the degradation record table records the rated parameter ranges, protection response types and corresponding protection levels of several electrical properties of the battery cell; for example, waterproof level, corrosion resistance level, high temperature resistance level, low temperature resistance level, and UV protection level; the corresponding protection parameter range is determined according to the protection level and corresponding technical documents, which is convenient for subsequent quantitative evaluation of the basic degradation rate and additional degradation rate of the cable under different working conditions.

[0035] S20: receiving a power anomaly report in real time, and updating information on a degradation record table of power components associated with the regional circuit model based on the power anomaly report to calculate an abnormal degradation level.

[0036] In this embodiment, the power anomaly report records the associated components, anomaly type, anomaly data, anomaly duration and anomaly degradation parameters; the power anomaly report is a report generated by extracting key information from the power fault event description reported by the user or power system inspectors.

[0037] Specifically, power anomaly reports are received in real time so as to be aware of fault phenomena occurring in the circuit system in real time, and information such as associated components, anomaly types, anomaly data, anomaly duration, and abnormal degradation parameters are obtained based on the power anomaly reports and input into the degradation record table of the associated power components to calculate the abnormal degradation level, so as to facilitate the subsequent evaluation of the additional degradation effects on power components such as cables caused by abnormal operation of the power network.

[0038] Wherein, in step S20, it includes: S21: receiving an abnormal power report in real time, retrieving a degradation record table affected by the abnormal power event based on the associated elements recorded in the abnormal power report, and inputting the abnormal type, abnormal data, abnormal duration and abnormal degradation parameters into the retrieved degradation record table.

[0039] Specifically, due to abnormal operating events occurring during the operation of the power network, such as short circuit faults, overload faults, mechanical damage and other faults, additional degradation of the cable will be caused beyond the natural aging of normal use. Therefore, the power anomaly report generated by monitoring the power network is received in real time, and all degradation record tables affected by the power anomaly event are retrieved based on the associated elements recorded in the power anomaly report. Data such as the anomaly type, anomaly data, anomaly duration and abnormal degradation parameters are input into the retrieved degradation record table to obtain the impact of the power anomaly event on each power component.

[0046] Specifically, when the natural environment in which the cables in the power network are located changes, for example, when natural disasters such as floods, typhoons, and freezing disasters occur, the cables will also suffer additional degradation beyond the natural aging caused by normal use, thereby having an additional impact on the degradation rate of the cables. Therefore, an environmental impact report generated by monitoring the environment of the monitored area is received in real time, and all degradation record tables in the monitored area are retrieved based on the environmental impact report. Data such as impact type, impact data, impact duration, and impact degradation parameters are input into the retrieved degradation record tables to obtain information on the impact of the environment of the monitored area on each power component.

[0047] S32: Process the performance parameter, impact type, impact data, impact duration, and impact degradation parameter based on the impact degradation algorithm built into the degradation record table, and calculate the corresponding impact degradation level.

[0049] S40: Calculating corresponding accumulated degradation parameters based on the abnormal degradation level and environmental degradation level of the target power element in each unit period.

[0050] Specifically, based on the abnormal degradation level and environmental degradation level of the target power element in each unit time period, the corresponding cumulative degradation parameters are calculated to improve the timeliness and scientificity of the cable degradation assessment through quantitative calculation.

[0051] Wherein, in step S40, it includes: S41: Determine target power components one by one, and determine the abnormal degradation level and environmental degradation level of the target power components in each unit time period.

[0052] Specifically, the target power elements are determined one by one, and the abnormal degradation level and environmental degradation level of the target power elements in each unit period are determined, so as to know the additional degradation speed of the target power elements in each unit period due to power abnormal events and surrounding environmental factors.

[0053] S42: Inputting the abnormal degradation level and the environmental degradation level into the degradation parameter algorithm built into the degradation record table to calculate the additional degradation parameters of each unit period.

[0054] Specifically, the abnormal degradation level and the environmental degradation level are input into the degradation parameter algorithm built into the degradation record table to calculate the additional degradation parameters of each unit period, so as to facilitate the quantitative analysis of the additional degradation degree of each power element.

[0055] S43: Calculating the accumulated degradation parameter of the target power element based on the basic degradation parameter of the target power element, a plurality of additional degradation parameters and the corresponding operation time.

[0056] Specifically, based on the basic degradation parameters of the target power element, several additional degradation parameters and the corresponding operation time, the accumulated degradation parameters of the target power element are calculated, so as to facilitate the determination of the current overall degradation status of each power element.
