Gradient
0 – 200 [% Pref /
Hz] / 40 [% Pref /
Hz] / 1
F
Set gradient of power limitation function with increasing frequency.
This percentage relates to the nominal frequency of 50 Hz.
Determines the active power reduction subject to the frequency.
The active power is reduced by a gradient in %-P
ref
. In the event of a fre-
quency deviation of one Hz, the configured reduction of the output
power is carried out. The percentage value relates to P
ref
, the actual
power level at the time the frequency exceeds the configured activation
threshold (PM).
NOTE: A drop in the range of 2 % to 12 % corresponds to a
gradient in the range of 100 %/Hz to 16 %/Hz.
