Digital twin technology provides a new solution for the fault diagnosis and rapid self-healing of intelligent distribution networks. By constructing a digital mirror image of the physical power grid system, real-time monitoring and analysis of the power grid operation status can be achieved, thus improving the accuracy and response speed of fault diagnosis. This paper explores how to use digital twin technology to optimize the fault detection, location, and restoration processes of the distribution network, in order to reduce power outage time and enhance power supply reliability. This system can significantly improve the efficiency of fault handling in the distribution network and enhance the safety and stability of the power grid. This research provides a theoretical basis and technical support for the development of smart grids.
