Distribution Network Fault Location Based on Time Reversal Considering Hybrid Power Network and Load

With the increasing attention to the power supply reliability of distribution network, the fault location method of distribution network as an important subject can be studied in depth. Traditional fault location methods, such as impedance method and traveling wave method, are limited due to the complex topology and many line types of distribution network. Based on the analysis of the limitations of impedance method and traveling wave method, this paper studies the fault location method of distribution network based on time reversal, focusing on the influence of hybrid power network and load on fault location method, Compared with the traditional fault location method, the distribution network fault location method based on time reversal has stronger adaptability.
