【Abstract】 The development of intelligent electronic device has brought substation automation technology into a new stage which is called full digital substation.This paper introduces the actuality of nowadays Substation Automation Systems(SAS) at the beginning,and then the actual problems of establishing communication networks in the digital SAS are particularized and the solutions are also discussed based on the analysis of digital SAS’ features and structure.At last,an instance using fiber Ethernet implementing the communication between IED which belongs to process layer and bay layer respectively is presented. This project is supported by Chinese National Programs for High Technology Research and Development(No.2005AA001200).更多还原
