Research on distribution network damage sensing model and method to cope with typhoon disaster

In recent years, the frequent occurrence of disasters such as typhoons, earthquakes, and lightning strikes has had a significant impact on the power infrastructure and seriously threatened the stability of the power grid. Therefore, it has become very urgent to build a 'resilient distribution network' that can not only prevent disasters, but also quickly restore power supply after disasters. This paper focuses on typhoon disasters, proposes a line fault section identification method based on feeder end point and smart meter information. On this basis, a strategy of using drone to patrol the line is proposed to locate the exact location of the fault. Taking IEEE 33-node system as test objects, the validity and correctness of the proposed method are verified.
