ANSI/IEEE C37.2 device number: I<->0 CB
10.1.2 Functionality
The circuit breaker control function CBXCBR is intended for circuit breaker control
and status information purposes. This function executes commands and evaluates
block conditions and different time supervision conditions. The function performs an
execution command only if all conditions indicate that a switch operation is allowed.
If erroneous conditions occur, the function indicates an appropriate cause value. The
function is designed according to the IEC 61850-7-4 standard with logical nodes
CILO, CSWI and XCBR.
The circuit breaker control function has an operation counter for closing and opening
cycles. The operator can read and write the counter value remotely from an operator
place or via LHMI.
10.1.3 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 user must ensure that the control commands are executed in a correct
sequence. This can be achieved, for example, with interlocking based on the status
indication of the related primary components. An example of how the interlocking
on substation level can be applied by using the IEC61850 GOOSE messages between
feeders is as follows:
