defined in the IED. Otherwise the default authority level, SuperUser, can handle the

Interlocking

Functionality

The interlocking functionality blocks the possibility to operate high-voltage
switching devices, for instance when a disconnector is under load, in order to prevent
material damage and/or accidental human injury.
Each control IED has interlocking functions for different switchyard arrangements,
each handling the interlocking of one bay. The interlocking functionality in each IED
is not dependent on any central function. For the station-wide interlocking, the IEDs
communicate via the station bus or by using hard wired binary inputs/outputs.
The interlocking conditions depend on the primary bus configuration and status of any
breaker or switch at any given time.

Logical node for interlocking SCILO

Identification

Function description
Logical node for interlocking
Functionality
The Logical node for interlocking SCILO function is used to enable a switching
operation if the interlocking conditions permit. SCILO function itself does not
provide any interlocking functionality. The interlocking conditions are generated in
separate function blocks containing the interlocking logic and provides SCILO its
input.
