9.21.2.1 Setting parallel operation method
You can use this parameter to set the parallel operation method. You can
select the following options:
Option Description
Master The device is designated as
the master.
Tap synchronization [►Sec-
tion 9.21.1.1, Page 217] par-
allel operation method
Follower The device is designated as
the follower.
Auto. tap sync. Automatic assignment of
master or follower.
If a master is not detected,
the device with the lowest
CAN bus address is auto-
matically designated as the
master. All other devices are
designated as followers.
Circulat. react. current Circulating reactive current minimization with CAN bus
communication [►Section 9.21.1.2, Page 218] parallel op-
eration method
Power factor Circulating reactive current minimization without CAN bus
communication [►Section 9.21.1.3, Page 220] parallel op-
eration method
Table70: Setting parallel operation method
Only change the parallel operation method when the on-load tap-changers
are not performing tap-change operations.
To select the parallel operation method, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Parallel operation
method.
2. Select the desired option.
3. Press the Accept button to save the modified parameter.
CAN bus address
You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. If the value is set to 0, then no communication takes place.
Circulating reactive current sensitivity
You can use this parameter to set the influence of circulating reactive current
on how the control deviation is calculated. The higher the set value, the
greater the calculated control deviation as a result of circulating reactive cur-
rent.
