Huawei SmartLogger3000 User Manual

Parameter Description Remarks
Power derating
caused by
overfrequency
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 derating.
-
Cuto
frequency of
overfrequency
derating (Hz)
Species the frequency threshold for cutting o
overfrequency 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.
Cuto power of
overfrequency
derating (%)
Species the power threshold for cutting o
overfrequency-caused derating.
Trigger
frequency of
overfrequency
derating (Hz)
The standards of certain countries and regions
require that the output active power of devices be
derated when the power grid frequency exceeds a
certain value.
Quit frequency
of
overfrequency
derating (Hz)
Species the frequency threshold for exiting
overfrequency derating.
Power drop
gradient of
overfrequency
derating (%/s)
Species the decrease rate of the overfrequency
derating power.
Power recovery
gradient of
overfrequency
derating (%/
min)
Species the recovery rate of the overfrequency
derating power.
Frequency
detection lter
time (ms)
Species the frequency detection lter time. -
Recovery delay
of frequency-
based active
power derating
Species the exiting delay time after the frequency
reaches the quit frequency of overfrequency
derating.
-
Execution delay
of frequency-
based active
power derating
Species the eective delay time of overfrequency
derating when the frequency reaches the trigger
frequency of overfrequency derating.
-
Hysteresis of
frequency-
based active
power derating
Species whether to enable overfrequency derating
hysteresis.
