Local/Remote operations
The local/remote selection affects CBXCBR and DCXSWI.
• 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.
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 and DCXSWI. 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.
