Parameter Description
VRT active Specifies the recovery rate
power recovery when the active current
gradient recovers to the value at the
moment before FRT.
Zero current due Specifies whether to enable
to power grid the Zero current due to
fault power grid fault function.
Overfrequency If this parameter is set to
derating 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.
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 recovery Specifies the power recovery
gradient of rate of the overfrequency-
overfrequency caused derating.
derating (%/
min)
Recovery delay Specifies the exiting delay
of frequency- time after the frequency
based active reaches the quit frequency of
power derating overfrequency-caused
derating.
