conformance-statement (MICS). The MICS provides the user with information for
the LNs provided within the IED; the PICS provides the user with information to
enable the IED to communicate with both SAS and other devices. See
Appendix:IEC61850 MICS, PICS, PIXIT and TICS
the user can obtain this information.
When TCP/IP operates, the IEDs can communicate with SAS computer, operator
workstation (OWS), engineering workstation (EWS), remote monitoring system, SNTP server.
In the SAS, the communication is served with the method of data transfer:
•
Report method of sending event messages like measurement, status, alarm and so on
•
GOOSE (Generic Object Oriented Substation Event) method of communication
between IEDs like interlock
•
Control method like controlling the circuit breaker (CB), the disconnector (DS), the
selector device (43), the transformer tap (TAP) and so on
