The application discloses a distribution network fault diagnosis system and method. The system includes: at least two power distribution terminals, a GIS system, at least two edge nodes, a central cloud node and an application terminal, wherein the edge node is used to determine the distribution network according to the distribution network information sent by the power distribution terminal connected to it When it is determined that there is a fault in the distribution network, the edge node is used to send the fault information to the central cloud node, and the central cloud node is used to judge the fault information again according to the GIS system. The power grid does have a fault, and the central cloud node is used to send the fault information to the application terminal. Through the "device-edge-cloud" management architecture design, data collection, data processing, and fault analysis can be performed on-site, reducing the data processing pressure and energy consumption of the central cloud node. At the same time, based on the GIS system, faults in the distribution network can be quickly located and the efficiency of operation and maintenance can be improved.
Description
technical field [0001] The embodiments of the present application relate to the field of distribution network technology, and in particular to a distribution network fault diagnosis system and method. Background technique [0002] With the continuous improvement of the automation degree of the distribution network, the amount of data collected by the terminal acquisition device in the distribution network is increasing exponentially. The current analysis and processing of massive data usually adopts traditional centralized cloud computing, that is, all IoT terminals upload data to the cloud platform, and the cloud platform performs data collection, storage and analysis in a unified manner to determine faults and push alarm information . [0003] However, this method has many processing links, and there is a delay in the network, so it is difficult to guarantee real-time performance, which is not conducive to timely fault diagnosis and troubleshooting, and cannot meet the fu...
