generator(s) can run slower than
system A.
• If the system A is the variable
system (i.e. generator), this
con󰈡guration is the maximum
allowed slip frequency then
generator(s) can run faster than
system B.
5712 Neg. freq. di󰆞erential CBA
(Negative frequency di󰈠erential CBA)
2 -0.49 to 0.00 Hz
[-0.18 Hz]
The prerequisite for a connect
command being issued for the CBA is
that the di󰈠erential frequency is
above the con󰈡gured di󰈠erential
frequency.
This setting is always in regards of
system A:
•
If the system B is the variable
system (i.e. generator), this
con󰈡guration is the maximum
allowed slip frequency then
generator(s) can run faster than
system A.
• If the system A is the variable
system (i.e. generator), this
con󰈡guration is the maximum
allowed slip frequency then
generator(s) can run slower than
system B.
5710 Voltage di󰆞erential CBA 2 0.50 to 20.00 %
[5.00 %]
The maximum permissible voltage
di󰈠erential for closing CBA is
con󰈡gured here.
Notes
If the di󰈠erence between system A
and system B voltage does not exceed
the value con󰈡gured here and the
system voltages are within the
operating voltage windows
(parameters
5800 / 5801 / 5810 /
5811), the command: "CBA close"
may be issued.
4.4.2.3.2 Phase Matching CBA
The following parameters are only valid if 'Synchronization CBA' (parameter
5730) is
con󰈡gured to 'Phase matching'.

The prerequisite for a connect
command being issued for the CBA is
that the leading phase angle between
system B and system A is below the
