Activation threshold
with underfrequency:
40 – 50 [Hz] / 40
[Hz] / 0.01
Activation threshold
with overfrequency:
50 – 60 [Hz] /
50.02 [Hz] / 0.01
Activation threshold (f1) underfrequency:
Determines the frequency threshold for activating the function in case
of underfrequency incidents. The active power adjustment is activated if
the frequency falls below the configured value and mode 1 or 2 is activ-
ated.
In mode 2, the function is deactivated if the frequency rises above the
configured value.
Activation threshold (f1) overfrequency:
Determines the frequency threshold for activating the function in case
of overfrequency incidents. The active power adjustment is activated if
the frequency rises above the configured value and mode 1 or 2 is activ-
ated.
In mode 2, the function is deactivated if the frequency falls below the
configured value.
Deact. Range lower
limit [Hz]
40 – 50 [Hz] / 47.5
[%/Hz] / 0.01
Only evaluated in mode 1.
The function is deactivated if the frequency returns to the deactivation
range and remains in this range for the duration of the deactivation
time.
Deact. Range upper
limit [Hz]
50 – 60 [Hz] / 50.5
[%/Hz] / 0.01
P(f) deactivation time
0 – 6,000,000 [ms] /
0 [ms] 1
Only evaluated in mode 1.
The function is deactivated if the frequency returns to the range
between the minimum and maximum deactivation threshold and re-
mains in this range for the duration of the deactivation time.
P(f) intentional delay
0 – 5,000 [ms] / 0
[ms] 1
The activation of the function based on the activation threshold is
delayed by the configured time.
Note 1: This function is regarded as critical for the stability of the trans-
mission grid and is therefore prohibited by several national grid connec-
tion regulations.
Note 2: This function is stipulated as a requirement by some domestic
grid connection directives in order to prevent any negative impact on is-
land detection. However, P(f) has no negative impact on KACO's en-
hanced island detection.
P(f) settling time
200 – 2,000 [ms] /
200 [ms] 1
Determines the dynamic behaviour in the event of a change in the act-
ive power limit. In the event of a change in frequency, the active power
is altered subject to a PT-1 characteristic curve using a settling time of 5
Tau.
The settling time is overlaid with the increasing and decreasing gradient.

Specifies the dynamic response on changing the active power for power
increase and decrease. With a voltage change, the active power is
changed with the specified gradient.
Note:
The gradient is overlaid with the settling time.
