The development of intelligent network urge automation of the transformer substations and control center. Information sharing and real-time communication is currently and urgently needed to research and solve the question. SCL is substation configuration language in IEC61850 standard, while CIM is the information model in IEC61970 standard which is used by control center. Their connection is very important for information sharing between substation and control center. Semantic network is a new concept and is a kind of knowledge representation method for artificial intelligence. It can show models internal connection and the connection between SCL and CIM. This paper uses semantic network to represent SCL, points out their similarities and differences, and puts forward mapping method for SCL and CIM. It will make the two models more convenient to share data and communication.
