Supervision of Communication Connections
SIPROTEC 5 devices offer extensive communication possibilities via fixed and optional interfaces. Beyond the
hardware supervision of the communication plug-in modules the transferred data must be monitored with
respect to their consistency, failure, or outage.
Supervision
With the supervision of the communication connections, every communication port is monitored selectively.
•
Failures are detected and indicated via the operational log. The device remains in operation!
•
Each port additionally is equipped with a separate communication log, with which details of the failures
(for example, error rate) are displayed.
Marking Fault Signals/Data
The signals/data affected by the failure are marked as invalid. In this way, the affected protection functions
can go into a secure state. In the following, some examples are named:
•
GOOSE signals can automatically be set to defined values in case of disturbed IEC 61850 communication.
•
Disturbed time-synchronization signals can lead to an automatic change of the source of time synchroni-
zation.
Normally, you can correct communication failures by checking the external connections or by replacing the
affected communication modules. In chapter to
in tabular form, of the error responses. Corresponding corrective measures can also be found there.
