Abstract

The invention discloses a power 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 centralcloud node and an application terminal. The edge nodes are used for determining the operation state of the power distribution network according to power distribution network information sent by a power distribution terminal connected with the edge node; and when it is determined that the operation state is that the power distribution network has a fault, the edge nodes are used for sending faultinformation to the central cloud node, the central cloud node is used for judging the fault information again according to the GIS system, and if the central cloud node judges that the power distribution network has a fault, the central cloud node is used for sending the fault information to the application terminal. Through the end-side-cloud management architecture design, data acquisition, dataprocessing and fault analysis can be carried out on site, and the data processing pressure and energy consumption of the central cloud node are reduced. Meanwhile, the power distribution network fault can be quickly positioned based on the GIS system, and the operation and maintenance efficiency is 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...
