Abstract

Embedded Ethernet technology has been utilized increasingly widely as the communication mode in the substation automation system (SAS). This paper introduces the current applying situation about embedded Ethernet in SAS First. After analyzing the protocol levels used in SAS based on embedded Ethernet and the differences between the TCP and UDP, UDP/IP is selected as the communication protocol between the station-level and bay-level devices for its real-time characteristic. Then a new kind of implementation of the embedded Ethernet is presented based on hardware protocol stack. The designed scheme can be implemented easily, reduce cost significantly and shorten developing cycle.
