IEC 61850^[1] is a standard for the design of electrical substation automation. IEC61850 is a part of the International Electrotechnical Commission’s (IEC) Technical Committee 57 (TC57)^[2] reference architecture for electric power systems. The abstract data models defined in IEC61850 can be mapped to a number of protocols. Current mappings in the standard are to MMS (Manufacturing Message Specification), GOOSE, SMV, and soon to Web Services. These protocols can run over TCP/IP networks and/or substation LANs using high speed switched Ethernet to obtain the necessary response times of < 4ms for protective relaying.

Other mappings have been proposed but are not yet standardized as is the case of the ACSI-CORBA mapping.
