1. > Configuration > Parallel operation.
ð Parallel operation method.
2. Press or until circulating reactive current appears in the dis-
play.
3. Press .
ð The parallel operation method is set.
When using the circulating reactive current parallel operation method, you
have to set the parameters for the circulating reactive current sensitivity
and circulating reactive current blocking .
Setting circulating reactive current sensitivity
The circulating reactive current sensitivity is a measure of its effect on the
behavior of the voltage regulator. At a setting of 0 % no effect is present.
With circulating reactive current relating to the rated current of the current
transformer, if you set the value to 10 % for example, this would cause the
voltage in the voltage regulator to be corrected by 10 %. This correction to
the voltage can be increased or decreased with this setting to attain the opti-
mum value.
As soon as you change the circulating reactive current sensitivity value, the
value for the result changes in the help text in the display.
To set the circulating reactive current sensitivity, proceed as follows:
1. > Configuration > Parallel operation > Press until the
desired parameter is displayed.
ð
Stability.
2. Press to increase the value or to reduce it.
3. If necessary, press to highlight the decimal place.
ð The decimal place is now highlighted and the value can be
changed.
4. Press .
ð The circulating reactive current sensitivity is set.
Setting circulating reactive current blocking
You can use this parameter to set the limit value for the maximum permissi-
ble circulating reactive current. If, during parallel operation, the circulating re-
active current exceeds the set limit value, then the following event is activat-
ed:
▪
Problem with parallel operation
All devices operating in parallel are blocked. Depending on the set delay
time for the parallel operation error message, the signaling relay Problem
with parallel operation is activated.
