Parameter
Description
Cutoff frequency
Specifies the frequency
of overfrequency
threshold for cutting off
derating (Hz)
overfrequency-caused
derating.
Cutoff power of
Specifies the power threshold
overfrequency
for cutting off overfrequency-
derating (%)
caused derating.
Trigger
The standards of certain
frequency of
countries and regions require
overfrequency
the output active power of
derating (Hz)
devices to be derated when
the power grid frequency
exceeds a certain value.
Quit frequency
Specifies the frequency
of overfrequency
threshold for exiting
derating (Hz)
overfrequency-caused
derating.
Power drop
Specifies the decrease rate of
gradient of
the overfrequency-caused
overfrequency
derating power.
derating (%/s)
Power recovery
Specifies the power recovery
gradient of
rate of the overfrequency-
overfrequency
caused derating.
derating (%/
min)
Frequency
Specifies the frequency
detection filter
detection filter time.
time (ms)
Recovery delay
Specifies the exiting delay
of frequency-
time after the frequency
based active
reaches the quit frequency of
power derating
overfrequency-caused
derating.
Execution delay
Specifies the effective delay
of frequency-
time of overfrequency-caused
based active
derating when the frequency
power derating
reaches the trigger frequency
of overfrequency-caused
derating.
Hysteresis of
Specifies whether to enable
frequency-based
overfrequency-caused
active power
derating hysteresis.

Remarks
● This parameter is
displayed when
the power
derating caused
by overfrequency
is set to Enable.
● The parameter
setting should
meet the
following
condition: Quit
frequency of
overfrequency
derating ≤
Trigger
frequency of
overfrequency
derating <
Cutoff frequency
of overfrequency
derating.
