Huawei SmartLogger3000 User Manual

Parameter Description Remarks
Voltage rise
suppression
The standards of certain countries and
regions require that when the output
voltage exceeds a certain value, the
inverter must suppress voltage rise by
outputting reactive power and reducing
active power.
-
Voltage rise
suppressing
reactive power
adjustment point
(%)
The standards of certain countries and
regions require that the inverter generate
a certain amount of reactive power when
the output voltage exceeds a certain value.
● This parameter is displayed
when Voltage rise
suppression is set to Enable.
● The value of Voltage rise
suppressing active power
derating point must be
greater than that of Voltage
rise suppressing reactive
power adjustment point.
Voltage rise
suppressing
active power
derating point
(%)
The standards of certain countries and
regions require that the active power of
the inverter be derated according to a
certain slope when the output voltage
exceeds a certain value.
Voltage rise
suppression P-U
curve
The standards of certain countries and
regions require that the P-U curve be set.
This parameter is displayed
when Voltage rise suppression
is set to Enable.
Voltage rise
suppression Q-U
curve
The standards of certain countries and
regions require that the Q-U curve be set.
Frequency
change rate
protection
Set this parameter to Enable to protect
the inverter when the grid frequency
changes too fast.
-
Frequency
change rate
protection
threshold (Hz/s)
Species the frequency change rate
protection threshold.
This parameter is displayed if
Frequency change rate
protection is set to Enable.
Frequency
change rate
protection
duration (s)
The inverter is protected when the grid
frequency change duration exceeds the
value.
Soft start time
after grid failure
(s)
Species the time for the power to
gradually increase when the inverter
restarts after the power grid recovers.
-
CT anomaly
detection
If this parameter is set to Enable, the
inverter automatically checks whether CT
cables are disconnected or connected in
reverse polarity and reports an alarm to
the SmartLogger.
