Study of Ethernet Technology in IEC61850

IEC 61850 is an unique substation automation standard which encompasses all the protection, control, measurement and monitoring functions. IEC61850 uses industrial Ethernet technology to provide services like Generic Object Oriented Substation Events (GOOSE), Manufacturing Message Specification (MMS) etc to be implemented at high speed. Using High speed Ethernet technology in GOOSE communication replaces point to point copper wiring between Intelligent Electronics Devices (IED). The study in this paper is conducted for understanding communication in GOOSE protocol using Ethernet technology. The Ethernet frame will analyzed in details in this paper.
