TDSC U0
You can use this parameter to set the desired value which is to be used
when the measured active power is 0.
1. Go to Settings > Parameters > Control > TDSC U0 .
2. Enter desired value at active power 0.
3. Press the Accept button to save the modified parameter.
TDSC Pmax/Pmin
You can use these parameters to set the maximum and minimum active
power value at which the maximum and minimum active power-dependent
desired value is to be used for regulation.
1. Go to Settings > Parameters > Control > TDSC Pmax/Pmin .
2. Enter active power for maximum/minimum 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:
| ± B | ≥ 0,6×
