No. Parameter Description Remarks
29 Underfrequency
rise power
The standards of certain countries
and regions require that when the
power grid frequency is lower
than the frequency threshold for
power raising, the device needs to
increase the active power output
to help increase the power grid
frequency. In this case, set this
parameter to Enable.
-
30 Power recovery
gradient of
underfrequency rise
power (%/min)
Species the power recovery rate
of underfrequency-caused raising.
This parameter is displayed
when Underfrequency rise
power is set to Enable.
31 Cuto frequency of
underfrequency rise
power (Hz)
Species the frequency threshold
for stopping underfrequency-
caused raising.
32 Cuto power of
underfrequency rise
power (%)
Species the power threshold for
stopping underfrequency-caused
raising.
33 Trigger frequency
of underfrequency
rise power (Hz)
Species the frequency threshold
for power raising.
34 Quit frequency of
underfrequency rise
power (Hz)
Species the exit frequency of
power raising caused by
underfrequency.
35 Limit value for
minimum PF of Q-
U characteristic
curve
Species the minimum power
factor for Q-U adjustment.
-
36 Power percentage
for triggering Q-U
scheduling
Species 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).
