Determines the dynamic behaviour in the event of a change in the acti-
ve power set value. With a voltage change, the active power is changed
according to a PT-1 characteristic curve with a settling time of 5 Tau.
Note: The settling time is overlaid with the increasing and decreasing
gradient.

Up to five nodes for voltage [V] and power [% Pref] are configurable.
The power value of the first and last value pair is also used as the maxi-
mum or minimum active power value that is valid across the limits of
the characteristic curve.

AVISO: Up to 5 characteristic curves can be configured independently

10.2.3 P(f)
Adjusting the active power P(f) in the event of overfrequency
Feed-in inverters must assist with frequency stability in the grid. If the grid frequency leaves the normal tolerance range
(e.g. ±200 mHz), then the grid will be in a critical state. In the event of overfrequency, there is a generation surplus, in the
event of underfrequency, there is a generation deficit.
PV systems must adapt their feed-in power relative to the frequency deviation. In the event of overfrequency, the power
adjustment is determined by a maximum feed-in limit. The actual power of the inverter may vary freely below this limit
due to a possible fluctuation in the available power or the target value, but at no time increases above the absolute po-
wer limit.

the reference power. In the case of PV inverters from KACO, P

is the specified activation th-
reshold.

Fig. 56: Equation 4
In some standards, the power adjustment is specified by a drop (s) instead of a gradient (g), as shown in equation 3 [Ver
figura 55] [
} Página 65]. The drop s can be transformed into a gradient g in accordance with equation 4 [Ver figura 56]
[ } Página 65].
The frequency f remains above the activation threshold
f
1
during an overfrequency incident. Consequently, the expres-
sion (
f

–
f
) is negative and ΔP corresponds to a reduction in the feed-in power.
