History
Multiple protocols exist for substation automation, which include many proprietary protocols with custom communication links. Interoperation of devices from different vendors would be an advantage to users of substation automation devices. An IEC project group of about 60 members from different countries worked in three IEC working groups from 1995. They responded to all the concerns and objectives and created IEC 61850. The objectives set for the standard were:
- A single protocol for complete substation considering modelling of different data required for substation.
- Definition of basic services required to transfer data so that the entire mapping to communication protocol can be made future proof.
- Promotion of high interoperability between systems from different vendors.
- A common method/format for storing complete data.
- Define complete testing required for the equipments which conforms to the standard.

Famous quotes containing the word history:
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
“... that there is no other way,
That the history of creation proceeds according to
Stringent laws, and that things
Do get done in this way, but never the things
We set out to accomplish and wanted so desperately
To see come into being.”
—John Ashbery (b. 1927)
“While the Republic has already acquired a history world-wide, America is still unsettled and unexplored. Like the English in New Holland, we live only on the shores of a continent even yet, and hardly know where the rivers come from which float our navy.”
—Henry David Thoreau (1817–1862)
