Figure 358: Control procedure in the SBO method
9.1.5 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, DCXSWI and ESXSWI. 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 the substation level can be applied using the IEC61850 GOOSE messages
between feeders.
