No. Category Parameter Description Remarks
46 Initial delay in
the frequency
sensitive mode
Species the delay response
time of frequency regulation.
-
47 Overfrequency
derating
Overfrequency
derating
If this parameter is set to
Enable, the active power of
the device will be derated
according to a certain slope
when the grid frequency
exceeds the frequency that
triggers overfrequency-caused
derating.
-
48 Cuto frequency
of overfrequency
derating (Hz)
Species the frequency
threshold for cutting o
overfrequency-caused
derating.
● 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 <
Cuto frequency
of overfrequency
derating.
49 Cuto power of
overfrequency
derating (%)
Species the power threshold
for cutting o overfrequency-
caused derating.
50 Trigger
frequency of
overfrequency
derating (Hz)
The standards of certain
countries and regions require
the output active power of
devices to be derated when
the power grid frequency
exceeds a certain value.
51 Quit frequency
of overfrequency
derating (Hz)
Species the frequency
threshold for exiting
overfrequency-caused
derating.
52 Power drop
gradient of
overfrequency
derating (%/s)
Species the decrease rate of
the overfrequency-caused
derating power.
53 Power recovery
gradient of
overfrequency
derating (%/
min)
Species the power recovery
rate of the overfrequency-
caused derating.
54 Frequency
detection lter
time (ms)
Species the frequency
detection lter time.
