Description

Distribution Network Fault Comprehensive Processing System

technical field

The utility model relates to a processing system which collects fault information of a power grid through multiple channels, automatically predicts the fault information, pushes the prediction result to emergency repairs and users, and interacts with users, and belongs to the technical field of power grid management.

Background technique

The existing power grid automatic management system does not form a comprehensive processing of grid faults, and the processing of fault information collection, judgment, notification to users, and command of fault repairs are all isolated and lack of connection with each other, and the processing results cannot be interacted with users . The specific performance is as follows:

1. The collection of fault information is single and isolated

The existing power grid fault information collection methods include 95598 repair report, user smart meter fault report, distribution transformer acquisition terminal fault report, line on-line switch fault report, and substation outlet switch fault report. However, the fault information obtained through these channels is not It is stored separately in their respective business systems. For example, the fault information reported by 95598 is stored in the 95598 customer service system, and the fault reported by the smart meter of the user is stored in the power consumption information collection system (CSM). The fault information reported by the outlet switch is stored in the distribution automation management system (DMS). It can be seen that the channels for collecting fault information of various existing power grid business systems are isolated (operating independently), the information collected by various channels lacks a unified external channel, and there is no connection between the fault information collected by various channels, so Existing grid automation business systems cannot share fault information collected from various channels at the same time, thus failing to meet the requirements for comprehensive analysis and utilization of grid fault information.

2. Lack of early automatic prediction of fault information

For a long time, when a fault occurs in the power distribution network, before entering the on-site emergency repair after the fault is reported, the fault information cannot be analyzed and the fault source and related equipment information can be accurately located. That is, the type of fault and the range of influence cannot be accurately judged in time. As a result, there is a lag in accurately locating the source of the fault and related equipment information, accurately obtaining the type of fault and the scope of influence during the emergency repair of a power failure, and relying on the confirmation of the emergency repair personnel after arriving at the scene, thus affecting the progress of emergency repair and the scheduling of emergency repair resources .

3. Fault information and emergency repair recovery cannot be pushed to the user end. For a long time, users can only obtain power outage information through TV, newspapers and the Internet. Real-time grasp of grid fault power outage information and estimated restoration time information. Although the existing 95598 customer service system of the power grid itself has the function of querying and releasing information about power outages, 95598 customer service personnel usually do not actively release information about power outages to users, and only inform users when they make inquiries. Emergency repair progress and estimated power restoration time information. In addition, during on-site emergency repairs, the emergency repair personnel cannot interact with the fault emergency repair system in real time, and the emergency repair work cannot be effectively supervised.
