Parameter
Description
Remarks
Active power
derating
threshold (%)
for voltage rise
suppression
The standards of certain countries and regions
require that the active power of the device be
derated by a certain slope when the output voltage
exceeds a certain value.
-
P-U
characteristic
curve
The device adjusts P/Pn (the ratio of the active
power to the rated power) in real time based on U/
Un(%) (the ratio of the actual power grid voltage
to the rated power grid voltage).
-
P-U
characteristic
curve
adjustment
time
Specifies the time from the response to the end of
the adjustment based on the P-U curve.
-
Frequency
regulation
The standards of certain countries and regions
require that if the power grid frequency fluctuates
around a certain value, the device needs to fine-
tune the active power output based on the
frequency regulation ratio to help stabilize the
power grid frequency. In this case, set this
parameter to Enable.
-
Adjustment
ratio of
frequency
modulation
control
Specifies the adjustment ratio of the active power
output.
This parameter is
displayed when the
Frequency regulation is
set to Enable.
Response
deadband of
frequency-
based control
Specifies the threshold for triggering the frequency
modulation control. For example, if this parameter
is set to 0.1 Hz, the frequency modulation control is
not triggered when the frequency is within reference
frequency±0.1 Hz.
-
Power change
gradient of
frequency-
based control
Specifies the active power change gradient of
frequency modulation.
-
Power change
limit of
frequency-
based control
Specifies the upper limit for active power
adjustment of frequency modulation.
-
Delay response
time of
frequency-
based control
Specifies the delay response time of frequency
modulation.
