[0028] The technical solution of the present invention is further described in detail below through specific embodiments.

[0029] Embodiment 1:

[0030] A method for rapid analysis of distribution network fault points based on 5G communication (see Appendix Figure 1), the power grid equipment operation data is detected by the corresponding sensor, the sensor is connected to the control console through the 5G communication network, the control console is connected to the mobile alarm terminal through the communication network, and the control console has a built-in GIS map, including the following steps:

[0031] Step 1: Initialize the GIS map and import the required monitoring targets and corresponding sensors and road data;

[0032] Step 2: configure the targets directly monitored by the sensor on the GIS map, and configure the targets monitored by combining the sensor detection data on the GIS map;

[0033] Step 3: Establish a fault detection model and configure the monitoring targets in the fault detection model on the GIS map;

[0034] Step 4: According to manual repair reports and sensor feedback, determine the power grid fault point and execute sub-steps including fault point navigation steps, equipment maintenance steps and fault point management according to needs.

[0035] In step 4, first determine whether the target directly monitored by the sensor has a fault. If there is a fault, obtain the fault point and mark it. Then determine whether the monitoring target monitored by the sensor detection data is faulty after being combined with each other. If there is a fault, obtain the fault point and mark it. Then, import the sensor data into the fault detection model, determine whether there is a fault according to the calculation of the fault detection model, and if there is a fault, obtain the fault point and mark it. Finally, all the fault points are fed back together. In step 4, the automation system fault information is studied and the full life cycle dynamic management of power outage faults is realized through fault information push, fault site location, fault process tracking, and fault problem archiving.

[0036] The original power outage repair mostly relies on the personal technical ability of the repair personnel. The repair process lacks records. The process is only organized through the recollections of key personnel afterwards, and typical cases are formed for dissemination, which restricts the dissemination efficiency of case analysis and experience analysis after the repair. This embodiment relies on manual on-site fault location and on-site picture and text feedback. It can also make the controller make a preliminary judgment on the fault based on the feedback of sensors (including meters). Then the relevant personnel can realize the dynamic management of the whole life cycle of fault repair through real-time communication, on-site command, result reporting, task archiving and auxiliary management through the fault repair task. When the sensor and manual repair are reported, a mobile terminal or monitor can be used to upload the on-site data and content in a combined manner. According to the on-site situation, the console can realize the on-site staff to carry out construction repair on the spot through the GIS map, and the backstage support personnel can cooperate in the backstage to achieve the repair goal. At the same time, the steps, content and gains and losses of the repair are recorded. The recorded content can provide further guidance in the next repair process, thereby forming a positive incentive. In this embodiment, the mobile terminal used can be a smart phone or other terminal device connected to the console. The connection between the terminal device and the console needs to be connected through a gateway. The terminal device needs to include at least voice call, photo taking and positioning functions.

[0037] The fault point navigation step includes the following sub-steps (see Appendix Figure 2 ):

[0038] A1. Read the fault point and fault type on the GIS map;

[0039] A2. Update the available roads on the GIS map according to the fault points and fault types;

[0040] A3. Determine the processing order according to the fault point and fault type, and then list all available roads between the fault points and the roads required to reach the first fault point according to the processing order to form several processing solutions;

[0041] A4. Comprehensively calculate the resources required for all treatment plans, select the one that requires the least resources as the navigation plan, and select the one that requires the second least resources as the backup plan.

[0042] The comprehensive calculation in step A4 refers to the weighted conversion data of the quantity of materials, route distance, and time required in the treatment plan. For example, in the treatment plan, it can be manually set that the weighted value of the quantity of materials required is 0.1, the weighted value of the route distance is 0.3, and the weighted value of the time spent is 0.6. The quantity of materials required is measured by weight. According to daily statistics, a conversion function is established with the average number of materials required for a single maintenance as the center. The result value range of the conversion function is set to 0 to 1. The average number of materials required for a single maintenance is 0.5. The conversion value of the materials required in the current plan is calculated and multiplied by the weighted value. Similarly, according to daily statistics, the average number of materials required for a single maintenance is used as the center. A conversion function is established with the distance of a single maintenance route as the center. The result value range of the conversion function is set to 0 to 1. The average value of the distance of a single maintenance route is 0.5. The conversion value of the required distance in the current solution is calculated and multiplied by the weighted value. According to daily statistics, a conversion function is established with the average time required for a single maintenance as the center. The result value range of the conversion function is set to 0 to 1. The average time required for a single maintenance is 0.5. The conversion value of the time required in the current solution is calculated and multiplied by the weighted value. The three weighted values ​​are added together and the data with the smallest value is selected. In the above scheme, the conversion function can be selected in the form of a normal distribution function, a bell-shaped membership function, etc.

[0043] The equipment maintenance step includes the following sub-steps (see Appendix Figure 3 ):

[0044] B1. Update the available roads on the GIS map according to the maintenance method of the monitoring target of this maintenance;

[0045] B2. According to the processing order of the monitoring targets of this maintenance, all available roads between the fault points and the roads required to reach the first fault point are listed in the processing order to form several processing plans;

[0046] B3. Comprehensively calculate the resources required for all treatment plans and select the one that requires the least resources as the maintenance plan;

[0047] B4. Update the monitoring target status of this maintenance on the GIS map according to the specific maintenance operations.

[0048] The fault point management includes fault point investigation, fault location positioning, fault repair and execution tracking, and fault archiving.

[0049] In this embodiment, based on the research and analysis of electronic map interaction under mobile GIS positioning technology, the electronic map interaction under GIS positioning technology is quickly realized to analyze and study the application technologies such as distribution network fault information interaction, emergency repair routes, and rapid planning. According to the fault information of the automation system, this project studies and realizes the dynamic management of the whole life cycle of power outages through fault information push, fault site location, fault process tracking, and fault problem archiving, and realizes fault point investigation feedback, fault location location, fault repair and execution tracking, and fault archiving.
