The grounding grid is an important part of the power system and plays a vital role in ensuring the safe operation of the converter station. In the traditional grounding grid construction process, the grounding design is mostly one-dimensional diagram, and due to the lack of effective welding coordinate positioning and grounding lead coordinate positioning, there are often problems such as construction defects, construction difficulty, and inconsistent acceptance standards, which increase the difficulties in the construction and acceptance process of the grounding grid and the process connection; The lack of visualization in the process of construction and operation and maintenance leads to the damage to the grounding system during the ground excavation process. With the continuous development of the power system, the requirements for the construction technology of the grounding grid are getting higher and higher, and the digital development has the basis for visualization research, so it is of great practical significance to carry out the research on the three-dimensional and mechanized construction of the grounding grid.
