(This table has been taken directly from the IEC 61850 Standard document)
 In a typical substation, all data attributes from each of the IEDs are desired at
the PLC.
 Data is desired at the Station PLC (for decision making) and at the SCADA
system
 Data gathered for Condition Based Monitoring purposes, to detect point of
degradation of an aging mechanism
 Examples of data needs: checking SF
6
gas insulation temperature
 Alarm data with high precision of accuracy needed, to determine which IED
alarmed (GOOSE’d) first
 Control of bay-level switchgear for interlocking and maintenance purposes
