Design method for intelligent substation communication based on intelligent device physical port modeling

The invention discloses a design method for intelligent substation communication based on intelligent device physical port modeling. The design method is based on a substation configuration and description method of international electrotechnical commission (IEC) 61850, and includes building a connection relation model of intelligent device physical network ports, building a model for the intelligent device physical network ports, building physical and logical connection relations between a switch and an intelligent device through drawing of auto computer aided design (AutoCAD) graphs, and presenting the connection relations intuitionally in a graphical mode, so that the intuitive control for network communication conditions in a design process is guaranteed, the design for the network communication in the design process is guaranteed, and the complete design of a communication system of the intelligent substation is accomplished.
