Activation threshold
with overfrequency
50.2 – 70 (Hz)
Activation threshold
with underfrequency
40 – 45 (Hz)
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.
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.
P(f) intentional delay
0 – 5000 [ms]
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.
Frequency of the max-
imum deactivation
threshold
45 - 50.2 (Hz)
Frequency of the min-
imum deactivation
threshold
45 – 50.2 (Hz)
Deactivation range lower limit:
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.
Deactivation range upper limit:
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.
P(f) deactivation time
0 – 3600 [s]
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) deactivation gradi-
ent
0 – 65534 [% / min]
If the available power is above the actual output at the time of deactiva-
tion, the power increase back to the maximum power is limited. The
limitation is implemented by an absolute power limitation that in-
creases with a continuous gradient up to the maximum power. The ac-
tual power of the inverter may vary freely below this limit due to a pos-
sible fluctuation in the available power or the target value, but at no
time increases above the absolute power limit.
