The method includes the content described in the following steps.

[0032] Step 21, collect the set of operating state information of the distribution network equipment.

[0033] In the embodiments of the present application, the set of operating state information of the distribution network equipment includes several groups of operating state information of the distribution network equipment (including but not limited to voltage state information, current state information, power consumption state information, etc., meter state information, transformer state information, etc.) that have a sequential order (continuous in time).

[0034] Step 22, use the set of operating state information of the distribution network equipment to determine the set of operating state information of the defective environment.

[0035] In the embodiments of the present application, the set of operating state information of the defective environment includes several groups of operating state information of the defective environment (including but not limited to equipment damage state information, equipment contamination state information, ambient temperature state information, ambient humidity state information, etc.) that have a sequential order.

[0036] In some possible examples, the use of the set of operating state information of the distribution network equipment to determine the set of operating state information of the defective environment described in step 22 can be implemented through step 221 and step 222.

[0037] Step 221, for each piece of operating state information of the distribution network equipment in the set of operating state information of the distribution network equipment, determine the first defective environment information set, the second defective environment information set, and the third defective environment information set through the operating state information optimization network.

[0038] In the embodiments of the present application, the operating state information optimization network is used to filter noise information, and the importance indices (ranging from 0 to 1) of the first defective environment information set, the second defective environment information set, and the third defective environment information set are different.

[0039] Step 222: Using the first defect environment information set, the second defect environment information set, and the third defect environment information set pointed to by each piece of distribution network equipment operation status information, determine the defect environment operation status information pointed to by each piece of distribution network equipment operation status information.

[0040] Designed in this way, by implementing Step 221 - Step 222, it is possible to determine the defect environment information set based on different importance indices, thereby ensuring the integrity and accuracy of the defect environment operation status information.

[0041] Step 23: Combining the set of distribution network equipment operation status information, determine the set of distribution network equipment status description distributions through the first status description mining subnet (which can be understood as a feature extraction subnet or a feature extraction module, etc.) covered by the distribution network equipment anomaly recognition network (such as a neural network model, including but not limited to CNN or LSTM, etc.).

[0042] In the embodiment of the present application, the set of distribution network equipment status description distributions includes several distribution network equipment status description distributions (which can be understood as the status feature maps of the distribution network equipment).

[0043] Step 24: Combining the set of defect environment operation status information, determine the set of defect environment status description distributions through the second status description mining subnet covered by the distribution network equipment anomaly recognition network.

[0044] In the embodiment of the present application, the set of defect environment status description distributions includes several defect environment status description distributions (which can be understood as the status feature maps of the defect environment / anomaly environment).

[0045] Step 25: Combining the set of distribution network equipment status description distributions and the set of defect environment status description distributions, determine the defect theme quantization possibility (this defect theme quantization possibility can be understood as the defect theme probability, for example, the defect theme quantization possibility A_0.6 can represent that the recognition probability of the defect theme "insulator damage" pointed to by the distribution network equipment operation status information is 0.6) pointed to by the set of distribution network equipment operation status information through the equipment defect recognition subnet (this equipment defect recognition subnet can be understood as a classification subnet, including but not limited to classifiers, support vector machines, etc.) covered by the distribution network equipment anomaly recognition network.

[0046] In some possible embodiments, the combination of the distribution set of the distribution network equipment state descriptions and the distribution set of the defect environment state descriptions described in step 25, and determining the quantization possibility of the defect theme pointed to by the distribution network equipment operation state information set through the equipment defect identification subnet included in the distribution network equipment anomaly identification network can be implemented through the technical solutions described in steps 251 to 254.

[0047] Step 251: Combine the distribution set of the distribution network equipment state descriptions, and determine a number of first array-type equipment state contents through the first equipment line structure local attention subnet included in the distribution network equipment anomaly identification network.

[0048] In the embodiments of the present application, each first array-type equipment state content (which can be understood as a feature vector, for example) is matched with a distribution network equipment state description distribution. Further, the equipment line structure local attention subnet can be understood as a spatial attention model or a spatial domain attention model.

[0049] Under some independently implementable design ideas, the combination of the distribution set of the distribution network equipment state descriptions described in step 251 and determining a number of first array-type equipment state contents through the first equipment line structure local attention subnet included in the distribution network equipment anomaly identification network may include the following: for each distribution network equipment state description distribution in the distribution set of the distribution network equipment state descriptions, determine the first individual refined state description distribution through the individual description refinement model included in the first equipment line structure local attention subnet; wherein, the first equipment line structure local attention subnet belongs to the distribution network equipment anomaly identification network; for each distribution network equipment state description distribution in the distribution set of the distribution network equipment state descriptions, determine the first group refined state description distribution through the group description refinement model included in the first equipment line structure local attention subnet; for each distribution network equipment state description distribution in the distribution set of the distribution network equipment state descriptions, combine the first individual refined state description distribution and the first group refined state description distribution, and determine the first global state description distribution through the moving average processing model included in the first equipment line structure local attention subnet; for each distribution network equipment state description distribution in the distribution set of the distribution network equipment state descriptions, combine the first global state description distribution and the distribution network equipment state description distribution, and determine the first array-type equipment state content through the first group description refinement model included in the first equipment line structure local attention subnet.

[0050] In the embodiments of the present application, the individual simplification corresponds to the max pooling process, and the group simplification corresponds to the average pooling process. Similar understandings can be made for the related simplification models, which will not be elaborated here. With such a design, the accuracy and feature recognition of the first array-type device status content can be ensured.

[0051] Step 252: Combine the defective environment state description distribution set, and determine a number of second array-type device status contents through the second device line structure local attention subnet covered by the distribution network device anomaly recognition network.

[0052] In the embodiments of the present application, each second array-type device status content is matched with a defective environment state description distribution.

[0053] For some independently implementable design ideas, the

[0054] Step 253: Perform a merging operation on the number of first array-type device status contents and the number of second array-type device status contents to obtain a number of target array-type device status contents.

[0055] In the embodiments of the present application, each target array-type device status content covers a first array-type device status content and a second array-type device status content. In addition, the merging operation can be understood as a splicing operation.

[0056] Step 254: Combine the number of target array-type device status contents, and determine the quantization possibility of the defect theme pointed to by the distribution network device operation status information set through the device defect recognition subnet covered by the distribution network device anomaly recognition network.

[0057] For some independently implementable design ideas, the combination of the number of target array-type device status contents described in Step 254 to determine the quantization possibility of the defect theme pointed to by the distribution network device operation status information set through the device defect recognition subnet covered by the distribution network device anomaly recognition network can be achieved through the following technical solution: Combine the number of target array-type device status contents, and determine the global array-type device status content through the device real-time demand local attention subnet covered by the distribution network device anomaly recognition network; wherein, the global array-type device status content is determined by using the number of target array-type device status contents and a number of time dimension importance indexes, and each target array-type device status content is matched with a time dimension importance index; Combine the global array-type device status content, and determine the quantization possibility of the defect theme pointed to by the distribution network device operation status information set through the device defect recognition subnet covered by the distribution network device anomaly recognition network.

[0058] In the embodiments of the present application, the device real-time demand local attention subnet can be understood as a time attention model or a time dimension attention model, and the globalized array-type device state content can be understood as a fused state feature vector, and the time dimension importance index can be understood as a time series weight. Thus, the quantization possibility of the defect theme can be determined based on the timeliness level, so as to ensure that the anomaly recognition will not be delayed as much as possible.

[0059] In some other possible embodiments, combining the above-mentioned several target array-type device state contents and determining the globalized array-type device state content through the device real-time demand local attention subnet covered by the distribution network device anomaly recognition network described in the above steps may include the following contents: combining the above-mentioned several target array-type device state contents and determining several first local array-type device state contents through the first local attention model covered by the device real-time demand local attention subnet; wherein, the device real-time demand local attention subnet belongs to the distribution network device anomaly recognition network; combining the above-mentioned several first local array-type device state contents and determining several second local array-type device state contents through the second local attention model covered by the device real-time demand local attention subnet; determining several time dimension importance indexes by using the above-mentioned several second local array-type device state contents; wherein, each time dimension importance index is matched with a target array-type device state content; determining the globalized array-type device state content by using the above-mentioned several target array-type device state contents and several time dimension importance indexes.

[0060] With such a design, through the divide-and-conquer idea and phased processing, the globalized array-type device state content can be determined completely and quickly.

[0061] It can be understood that through step 251-step 254, the corresponding feature vector can be determined by means of the device line structure local attention subnet, and the quantization possibility of the defect theme can be accurately determined based on the fusion of the feature vectors.

[0062] Under some independently implementable design concepts, the combination of the distribution set of the power distribution network equipment state description and the distribution set of the defect environment state description, and the determination of the quantization possibility of the defect theme pointed to by the power distribution network equipment operation state information set through the equipment defect identification subnet covered by the power distribution network equipment anomaly identification network can be achieved through the following technical solutions: Combine the distribution set of the power distribution network equipment state description, and determine a number of first array-type equipment state contents through the first group description reduction model covered by the power distribution network equipment anomaly identification network; wherein, each first array-type equipment state content is matched with a power distribution network equipment state description distribution; Combine the distribution set of the defect environment state description, and determine a number of second array-type equipment state contents through the second group description reduction model covered by the power distribution network equipment anomaly identification network; wherein, each second array-type equipment state content is matched with a defect environment state description distribution; Perform a merging operation on the number of first array-type equipment state contents and the number of second array-type equipment state contents to obtain a number of target array-type equipment state contents; wherein, each target array-type equipment state content covers a first array-type equipment state content and a second array-type equipment state content; Combine the number of target array-type equipment state contents, and determine the globalized array-type equipment state content through the equipment real-time demand local attention subnet covered by the power distribution network equipment anomaly identification network; wherein, the globalized array-type equipment state content is determined by using the number of target array-type equipment state contents and a number of time dimension importance indexes, and each target array-type equipment state content is matched with a time dimension importance index; Combine the globalized array-type equipment state content, and determine the quantization possibility of the defect theme pointed to by the power distribution network equipment operation state information set through the equipment defect identification subnet covered by the power distribution network equipment anomaly identification network.

[0063] Step 26, use the quantization possibility of the defect theme to determine the anomaly identification situation of the power distribution network equipment operation state information set.

[0064] In the embodiment of the present application, the anomaly identification situation can be determined by comparing the quantization possibility of the defect theme with a set probability. For example, if the probability 0.9 corresponding to the quantization possibility of the defect theme B_0.9 is greater than the set probability 0.8, it can be determined that the anomaly identification situation of the power distribution network equipment operation state information set is the defect theme "transformer breather defect" corresponding to the quantization possibility of the defect theme B_0.9.

[0065] Exemplarily, the anomaly identification of the equipment body defects in the present application mainly includes: transformer, CT / PT oil leakage identification, meter breakage identification, insulator breakage identification, transformer breather defect identification, equipment surface pollution identification, etc., but not limited thereto.

[0066] In summary, when applied to the embodiments of the present application, first, a set of operation status information of distribution network equipment is collected, then a set of operation status information of the defect environment is determined according to the set of operation status information of the distribution network equipment. Based on the set of operation status information of the distribution network equipment, a set of distribution of device status descriptions of the distribution network equipment is determined through the first status description mining subnet included in the distribution network equipment anomaly recognition network. And based on the set of operation status information of the defect environment, a set of distribution of defect environment status descriptions is determined through the second status description mining subnet included in the distribution network equipment anomaly recognition network. Then, based on the set of distribution of device status descriptions of the distribution network equipment and the set of distribution of defect environment status descriptions, the quantization possibility of the defect theme pointed to by the operation status information of the distribution network equipment is determined through the device defect recognition subnet included in the distribution network equipment anomaly recognition network. Subsequently, the anomaly recognition situation of the set of operation status information of the distribution network equipment is determined according to the quantization possibility of the defect theme.

[0067] Through the above technical solution, after obtaining the set of operation status information of the distribution network equipment, the set of operation status information of the defect environment can be further determined.

Further, by integrating different distributions of status descriptions and invoking the device defect recognition subnet, the quantization possibility of the defect theme pointed to by the operation status information of the distribution network equipment can be accurately located. In this way, the anomaly recognition situation corresponding to the set of operation status information of the distribution network equipment can be accurately located according to the quantization possibility of the defect theme, so as to analyze from both the device operation level and the defect environment level to improve the accuracy and credibility of the anomaly recognition of the distribution network equipment.
