Operating Manual
8.1.11 "VArCtlVol" Procedure
The reactive power is set depending on the line voltage. The reactive power target value is adjusted
in stages.
Figure 14: Characteristic curve for reducing reactive power depending on line voltage
If the line voltage changes by the parameterizable voltage difference "Q-VDif" for the configurable
duration of "Q-VDifTm", the reactive power target value is adapted by the value "Q-VArGr".
The parameterization of this function depends on the medium voltage.
