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.
5700 Voltage di󰆞erential CBB 2 0.50 to 20.00 %
[5.00 %]
The maximum permissible voltage
di󰈠erential for closing CBB 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: "CBB close"
may be issued.
4.4.2.4.2 Phase Matching CBB
The following parameters are only valid if 'Synchronization CBB' (parameter
5729) is
con󰈡gured to 'Phase matching'.

Description
5703 Max. positive phase angle CBB 2 0.0 to 60.0 °
[7.0 °]
The prerequisite for a connect
command being issued for the CBB is
that the leading phase angle between
system B and system A is below the
con󰈡gured maximum permissible
angle.
5704 Max. negative phase angle CBB 2 -60.0 to 0.0 °
[-7.0 °]
The prerequisite for a connect
command being issued for the CBB is
that the lagging phase angle between
system B and system A is above the
con󰈡gured minimum permissible
angle.
5707 Phase matching CBB dwell time 2 0.0 to 60.0 s
[3.0 s]
This is the minimum time that the
system A/B voltage, frequency, and
phase angle must be within the
con󰈡gured limits before the breaker
will be closed.
