No. Category Parameter Description Remarks
39 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).
-
40 P-U
characteristic
curve
adjustment time
Species the time from the
response to the end of the
adjustment based on the P-U
curve.
-
41 Frequency
modulation
control
Frequency
modulation
control
The standards of certain
countries and regions require
that if the power grid
frequency uctuates around a
certain value, the device
needs to
ne-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.
-
42 Adjustment ratio
of frequency
modulation
control
Species the adjustment ratio
of the active power output.
This parameter is
displayed when the
frequency regulation
control is set to
Enable.
43 Response
deadband of
frequency-based
control
Species the threshold for
triggering the frequency
regulation control. For
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.
-
44 Power change
gradient of
frequency-based
control
Species the active power
change gradient of frequency
regulation.
-
45 Power change
limit of
frequency-based
control
Species the upper limit for
active power adjustment of
frequency regulation.
