3.1.1 Bay control QCBAY
The Bay control (QCBAY) is used to handle the selection of the operator place per bay. The
function gives permission to operate from two main types of locations either from Remote
(for example, control centre) or from all (Local and Remote). The Local/Remote switch position
can also be set to Off, which means no operator place selected that is, operation is not
possible either from local or from remote.
For IEC 61850-8-1 communication, the Bay Control function can be set to discriminate between
commands with orCat station and remote (2 and 3). The selection is then done through the IEC
61850-8-1 edition 2 command LocSta.
QCBAY also provides blocking functions that can be distributed to different apparatuses
within the bay. There are two different blocking alternatives:
• Blocking of update of positions
• Blocking of commands
