No. Parameter Description Remarks
32 Cuto power of
underfrequency rise
power (%)
Species the power threshold for
stopping underfrequency-caused
raising.
33 Trigger frequency
of underfrequency
rise power (Hz)
Species the frequency threshold
for power raising.
34 Quit frequency of
underfrequency rise
power (Hz)
Species the exit frequency of
power raising caused by
underfrequency.
35 Limit value for
minimum PF of Q-
U characteristic
curve
Species the minimum power
factor for Q-U adjustment.
-
36 Power percentage
for triggering Q-U
scheduling
Species the reference apparent
power in percent. When the
actual apparent power of the
device is greater than the value of
this parameter, the Q-U
characteristic curve scheduling
function is enabled.
-
37 Q-U characteristic
curve
The device adjusts Q/S (the ratio
of the output reactive power to
apparent power) in real time
based on U/Un(%) (the ratio of
the actual power grid voltage to
the rated power grid voltage).
-
38 Q-P characteristic
curve
The device adjusts Q/Pmax (the
ratio of the reactive power to the
maximum active power) in real
time based on P/Pmax (the ratio
of the active power to the
maximum active power).
-
39 Cosφ-P/Pn
characteristic curve
The device adjusts the output
power factor cosφ in real time
based on P/Pn (%).
