6.6 IEC 61850 Standard Introduction
IEC 61850 is primarily focused on electrical utility stations and substations.
Substations can be categorized as distribution or transmission substations.
Distribution substations generally have feeder equipment in the voltage range of
30 kV and under. The one or two incoming feeders are generally at a
transmission voltage level. A transmission substation would have feeder
equipment at a transmission voltage level, generally 100 kV and above.
Although IEC 61850 applications are primarily in electrical substations, there are
applications in the oil and gas industries as well (co-gen sites).
6.6.1 Integrating the Substation
The Logical nodes can inter-operate with other logical nodes by interpreting and
processing compatible services and data classes.
