VArCtlVolHystDb Specifies the
reactive power
depending on the
line voltage
(Q = f(U)
characteristic curve)
Q-VArNom Reactive power in
% − 100% … 100% ‒ 0%
Q-VArTmsSpnt* Time setting of the
characteristic curve
point 1 s … 60 s ‒ 10 s
Q-VArTmsVtg* Delay of line
voltage 1 s … 60 s ‒ 10 s
Q-VDif* Definition of the
voltage change that
leads to a reactive
power change. 0.1% … 10% The value
corresponds to the
nominal voltage
"VRtg". 1%
Q-VDifTm* Time span in which
a voltage change
must be present
before the reactive
power target value
"Q-VArGra"
changes. 0 s … 120 s ‒ 1 s
Q-VolNomP1* Voltage at point 1 80% … 120% ‒ 100%
Q-VolNomP2* Voltage at point 1 80% … 120% ‒ 100%
