To strengthen the application of digital twin technology in the power grid, the application of digital twin technology to substation grounding networks is studied. The corrosion state of the substation grounding network will affect the stable operation of the power system to a certain extent, so this paper proposes a non-destructive testing based on electrochemical corrosion detection technology to realize the corrosion process, and maps the detection results to the virtual model through digital twin technology. The results of engineering practice show that the method can be used to evaluate the corrosion tendency and corrosion rate of the substation grounding network and realize the long-term monitoring and automatic inspection of the grounding network operation and maintenance.
