Research on Digital Design of Intelligent Substation Based on Graph and Mould

With the development of the smart grid, the structure and technical of the secondary system of the smart substation have changed dramatically. The latest communication and information processing technology separate the physical layer and the logical layer, and the information in the logical layer is transmitted through optical cable, which makes it invisible. At present, the core problems of intelligent station design are that the design process is not systematic, and the design documents do not correspond to the engineering documents. The paper proposes effective solutions to these problems.
