No. Category Parameter Description Remarks
29 VRT active
power recovery
gradient
Species the recovery rate
when the active current
recovers to the value at the
moment before FRT.
-
30 Zero current due
to power grid
fault
Species whether to enable
the Zero current due to
power grid fault function.
-
31 Frequency
control
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.
-
32 Cuto frequency
of overfrequency
derating (Hz)
Species 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.
33 Cuto power of
overfrequency
derating (%)
Species the power threshold
for cutting o overfrequency-
caused derating.
34 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.
35 Quit frequency
of overfrequency
derating (Hz)
Species the frequency
threshold for exiting
overfrequency-caused
derating.
36 Power recovery
gradient of
overfrequency
derating (%/
min)
Species the power recovery
rate of the overfrequency-
caused derating.
37 Recovery delay
of frequency-
based active
power derating
Species the exiting delay
time after the frequency
reaches the quit frequency of
overfrequency-caused
derating.
