The efficiency of accident handling is particularly important for the continuity of planned operations and the stability of distribution network operation. Therefore, it is very necessary to improve the efficiency of accident handling.

[0004] However, the current distribution network accident handling process is cumbersome. When the distribution network automation system or D5000 displays a fault alarm or the monitoring informs of fault information, the dispatcher needs to manually enter the fault log, notify the relevant units of the fault information by phone, maintain and push power outage information in real time, and verbally issue operating instructions and permissions. It involves many links, a long execution cycle, and great safety risks. The existing accident handling methods and systems can no longer meet the needs of dispatching work, and there is an urgent need to improve quality and efficiency through intelligent technology.

[0017] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Figure 1 A flow chart of a method for intelligent analysis and reporting of distribution network faults supported by power grid dispatching technology provided by an exemplary embodiment of the present application is shown. The method is described by taking the application of the method in a computer device as an example. The method includes: Step 101, obtaining accident information.

[0019] In the embodiment of the present application, the accident information corresponds to the target accident. Optionally, the target accident is an accident that causes a power outage in the power distribution environment.

[0020] Step 102: Generate an accident category and an accident log corresponding to the target accident based on the accident information.

[0021] In the embodiments of the present application, the accident category is used to indicate the specific type of the target accident. It should be noted that there is a corresponding relationship between the accident category and the template of the accident log. Therefore, in some embodiments of the present application, there is a sequential relationship between the determination of the accident category and the generation of the accident log.

[0022] Step 103: Generate outbound call information corresponding to the target accident based on the accident category.

[0023] The outbound call information can be implemented as communication information within the power grid, or as information sent to customers based on the power grid marketing system. This application does not limit the actual implementation form of the outbound call information.

[0024] Step 104, in response to the generation of the outbound call information, the process information corresponding to the target accident is obtained.

[0025] Optionally, after the outbound call information is generated, in an embodiment of the present application, the computer device will monitor the progress of on-site handling of the target accident in real time.

[0026] Step 105 , in response to the process information indicating that the target accident has been handled, an accident maintenance log corresponding to the target accident is generated.

[0027] Optionally, after the target accident is handled, the computer device fills in the accident maintenance log. In some embodiments, the accident maintenance log corresponds to a template of the accident maintenance log.

[0028] Next, for Figure 2 A flow chart of another method for intelligent analysis and reporting of distribution network faults supported by power grid dispatching technology provided by an exemplary embodiment of the present application is shown. The method is described by taking the application of the method in a computer device as an example. The method includes: Step 201, obtaining accident information.

[0029] In the embodiment of the present application, the accident information includes power grid dispatching system accident information, distribution automation system accident information and monitoring system accident information.

[0030] Step 202: Determine the fault phenomenon information, fault range information, and fault protection category information corresponding to the target accident based on the accident information.

[0031] Step 203: determine the category corresponding to the target accident based on the fault phenomenon information, the fault range information, and the fault protection category information.

[0032] Step 204: Generate an accident log corresponding to the target accident in combination with the category.

[0033] Step 205: Determine the grounding situation corresponding to the target accident based on the accident type and the accident log.

[0034] Step 206 , in response to the accident type and the accident log indicating that the grounding condition is a one-way line grounding, determining the grounding test completion condition information corresponding to the target accident.

[0035] Step 207 , in response to the completion of the grounding test, or in response to the grounding condition corresponding to the target accident being a non-unidirectional line grounding, an outbound call information corresponding to the target accident is generated.

[0036] Step 208, obtaining marketing system resource information.

[0037] Step 209: Generate information publishing instructions based on the marketing system resource information.

[0038] In the embodiment of the present application, the information release instruction is used to instruct to publish information associated with the target accident through communication means.

[0039] It should be noted that in the embodiment of the present application, the method for generating the accident handling operation ticket is to obtain typical ticket template information and network command technical information, and generate the accident handling operation ticket based on the typical ticket template and network command technical information.

[0040] Step 210 , in response to the process information indicating that the target accident has been handled, a power transmission instruction is generated, where the power transmission instruction is used to instruct the issuance of a power transmission notification.

[0041] Step 211 , in response to the process information indicating that the target accident has been handled, an accident maintenance log corresponding to the target accident is generated.

[0042] It should be noted that in the embodiment of the present application, before performing maintenance log scanning, the computer device needs to determine the change of the power outage range. Optionally, in response to the target accident not being handled, determine the change of the power outage range corresponding to the target accident; in response to the power outage range not changing, update the accident handling operation ticket; in response to the power outage range changing, update the information release instruction and the accident handling operation ticket.

[0043] That is, in combination with existing products of the power grid and actual marketing technology, in one example, the specific operation method involved in this application includes the following steps: (1) Based on the existing power grid dispatching technical support system, the distribution automation system and the D5000 system are actively connected to automatically receive the fault information of the above systems, including the start time, fault range, trip switch, protection and safety automatic device action, FA action, etc. The intelligent analysis and reporting system classifies the fault according to the fault range and related protection actions (full line tripping, branch tripping, busbar power failure, etc.), and automatically generates accident logs based on different types of fault templates.

[0044] (2) For accident information that the distribution automation and D5000 system cannot automatically push, such as single-phase grounding or voltage transformer fuse blowing, the dispatcher determines the type of accident based on the fault phenomenon reported by the monitoring system, generates an accident log based on the corresponding template, and allows the monitoring system to perform a single-phase grounding test operation or notify relevant personnel to check the corresponding equipment.

[0045] (3) After the accident log is entered and the single-phase grounding test is completed, the intelligent analysis and reporting system actively matches the faulty line and its substation, and automatically determines the target units to be notified, including the distribution operation and inspection branch, substation operation and maintenance team, electricity inspection team, etc. At the same time, the system notifies the relevant units of the fault information and line inspection scope at one time based on voice-to-text technology, realizing intelligent outbound calls for fault information.

[0046] (4) After the intelligent outbound call in step (3) is completed, the intelligent analysis and reporting system, in combination with the marketing system, accurately pushes outage information to the outside world through phone calls, text messages, etc., including the scope of the fault, the start time of the fault, and information about various types of users affected by the accident. At the same time, as the accident handling progresses, when the scope of the fault changes, the system updates the outage information to the outside world in real time.

[0047] (5) The system uses typical tickets, intelligent ticketing, and reversible operation tickets to accurately and quickly write accident handling operation tickets, thereby improving the efficiency of accident handling. It also uses network command technology to avoid the mistakes that may be caused by manual command issuance in previous accident handling, thereby improving the safety level of dispatching operations. At the same time, when the fault scope changes, return to step (4) to update the power outage information.

[0048] (6) After the accident is handled, a power supply notification is issued with one click, the number of households affected by the power outage is automatically counted, and the accident log is maintained in a timely manner.

[0049] To sum up, the method provided in the embodiment of the present application, during the process of target accident reporting, obtains the accident category of accident information and the accident log, and generates outbound call information, and generates an accident maintenance log after the target accident is handled. It combines automation technology to realize the networking and intelligentization of the accident handling process, effectively solves the operational risks that may be caused by oral commands for accident handling, and further improves the efficiency of scheduling work.

[0050] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
