[0038] S101, obtaining original information of a distribution automation terminal, where the original information includes input information and output information of the distribution automation terminal.

[0039] In this step, original information of the distribution automation terminal is obtained, and the original information includes input information and output information of the distribution automation terminal.

[0040] Furthermore, distribution automation terminals are key equipment in the distribution automation system. They are installed in the distribution and are used to realize functions such as data acquisition, control and communication. Distribution automation terminals mainly include feeder terminals (FTU), station terminals (DTU) and distribution transformer terminals (TTU). In the distribution automation monitoring system, the distribution automation terminal is used to transmit information between the distribution automation master station and the protection and measurement and control device. In order to monitor the accuracy of information transmission of the distribution automation terminal, a monitoring device is set at the communication interface between the distribution automation terminal and the distribution network automation master station, and between the distribution automation terminal and the protection and measurement and control device to obtain the original information of the distribution automation terminal, wherein the original information includes the input information and output information of the distribution automation terminal.

[0041] Specifically, the input information is the information sent by the distribution automation master station to the distribution automation terminal, and the output information is the information sent by the distribution automation terminal to the protection and measurement and control device.

[0042] S102: Determine data information of the distribution network automation terminal based on the original information, where the data information includes first data information and second data information.

[0043] After completing the above step S101, in this step, data information of the distribution network automation terminal is determined based on the original information, and the data information includes first data information and second data information.

[0044] Further, Figure 2 A flowchart of the steps of determining the data information of the distribution network automation terminal based on the original information is shown, such as Figure 2 As shown, determining the data information of the distribution network automation terminal based on the original information includes the following steps:

[0045] S201, determining a timing tag of the original information.

[0046] In this step, the timing tag of the original information is determined.

[0047] Specifically, the time information when the monitoring device receives the data information is determined, and the time information is used to represent the receiving time of the data information, so as to distinguish the data information.

[0048] S202: Determine data information of the distribution network automation terminal based on the timing tag and the original information, where the data information includes first data information and second data information.

[0049] After completing the above step S201, in this step, the data information of the distribution automation terminal is determined based on the timing tag and the original information, and the data information includes the first data information and the second data information.

[0050] Specifically, after determining the time information when the monitoring device receives the data information, a time tag is added to all the information data, wherein the time tag is added to the input information to obtain the first data information, and the time tag is added to the output information to obtain the second data information.

[0051] S103: Determine fault information of the distribution network system based on the data information.

[0052] After completing the above step S102, in this step, the fault information of the distribution network system is determined based on the data information.

[0053] Further, Figure 3 A flow chart showing the steps of determining the fault information of the power distribution network system based on the data information is shown. Figure 3 As shown, determining the fault information of the distribution network system based on the data information includes the following steps:

[0054] S301, obtaining message information of the distribution network automation master station.

[0055] In this step, the message information of the distribution network automation master station is obtained, wherein the message information is used to represent the information sent by the distribution network automation master station to the distribution automation terminal.

[0056] S302: Determine an information combination based on the message information, the first data information and the second data information.

[0057] After completing the above step S301, in this step, an information combination is determined based on the message information, the first data information and the second data information.

[0058] Specifically, after acquiring the message information sent by the distribution network automation master station, the second data information received by the distribution automation terminal, and the third data information sent by the distribution automation terminal, they are sorted and arranged in the order of time tags, and the same time tags constitute an information combination.

[0059] S303: Determine fault information of the distribution network system based on the information combination.

[0060] After completing the above step S302, in this step, the fault information of the distribution network system is determined based on the information combination.

[0061] In the process of information transmission, in principle, the information sent by the distribution network automation master station and the information received and sent by the distribution automation terminal should correspond to each other. The contents of the message information, the first data information and the second data information in the information combination are compared to determine the missing or inconsistent relief, so as to find the fault information and locate the fault information.

[0062] In order to improve the accuracy of diagnosis, before obtaining the data information of the distribution automation terminal, the automatic diagnosis method of the distribution monitoring system defects also includes: obtaining the time information of the distribution automation master station, and synchronizing the time information of the distribution monitoring system based on the time information, so that the distribution automation master station and the distribution monitoring system have the same time information, avoiding the matching errors of the message information, the first data information and the second data information caused by different time information during the sampling process.

When the distribution automation terminal communication monitoring device receives data information from the monitoring device, it will add a time tag to all information data according to the unified time reference. The distribution automation terminal communication monitoring device will sort and sort the data information with the time tag, and send it to the intelligent analysis master station in a unified format. The intelligent analysis master station deploys a probe at the distribution network automation master station to monitor the interactive data between the distribution network automation master station and the distribution automation terminal, and the data is also marked with a time tag. The intelligent analysis main station sorts the collected data according to the unified time label, and compares and analyzes the three parts of the monitored data to find out the missing, erroneous and inconsistent links, so as to realize automatic fault location.
