Parameter
Description
P-U
The device adjusts P/Pn (the
characteristic
ratio of the active power to
curve
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
Specifies the time from the
characteristic
response to the end of the
curve
adjustment based on the P-U
adjustment time
curve.
Frequency
The standards of certain
modulation
countries and regions require
control
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
Specifies the adjustment ratio
of frequency
of the active power output.
modulation
control
Response
Specifies the threshold for
deadband of
triggering the frequency
frequency-based
regulation control. For
control
example, if this parameter is
set to 0.1 Hz, the frequency
regulation control is not
triggered when the frequency
is within reference frequency
±0.1 Hz.
Power change
Specifies the active power
gradient of
change gradient of frequency
frequency-based
regulation.
control
Power change
Specifies the upper limit for
limit of
active power adjustment of
frequency-based
frequency regulation.
