Table 43: BCD-coded desired value
Setting desired value 1
1. Go to
Settings > Parameters > Grid > Control > Desired value
.
2. Enter the desired value.
3. Press the
Accept
button to save the modified parameter.
Bandwidth
You can use this parameter to set the maximum permissible deviation of the
measured voltage U
actual
from the desired value U
desired
.
In order to set the correct value, the transformer step voltage and nominal
voltage must be known. Note that a large bandwidth will result in a large
control deviation.
The bandwidth must always be greater than the following value:
