Figure 189: Control procedure in the SBO method
Local/Remote operations
The local/remote selection affects CBXCBR.
• Local: the opening and closing via communication is disabled.
• Remote: the opening and closing via LHMI is disabled.
•
AU_OPEN
and
AU_CLOSE
inputs function regardless of the local/remote
selection.
8.1.5 Application
In the field of distribution and sub-transmission automation, reliable control and
status indication of primary switching components both locally and remotely is in a
significant role. They are needed especially in modern remotely controlled
substations.
Control and status indication facilities are implemented in the same package with
CBXCBR. When primary components are controlled in the energizing phase, for
example, the correct execution sequence of the control commands must be ensured.
This can be achieved, for example, with interlocking based on the status indication of
the related primary components. The interlocking on substation level can be applied
using the IEC 61850 GOOSE messages between feeders.
