Parameter
Description
Remarks
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).
-
Q-U characteristic
curve mode
Specifies the reactive power
compensation mode of the device
output.
-
Delay for Q-U
characteristic curve
to take effect
Specifies the delay time for Q-U
adjustment.
-
Power percentage
for triggering Q-U
scheduling
Specifies the reference apparent power
in percentage. 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.
-
Power percentage
for exiting Q-U
scheduling
Specifies the P/Pn when the device
exits the Q-U scheduling.
-
Minimum PF of Q-U
characteristic curve
Specifies the minimum power factor
for Q-U adjustment.
-
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).
-
PF-U characteristic
curve
The device adjusts the power factor in
real time based on U/Un(%) (the ratio
of the actual power grid voltage to the
rated power grid voltage).
-
PF-U voltage
detection filter time
Specifies the time for filtering the grid
voltage in the PF-U curve.
-
cosφ-P/Pn
characteristic curve
The device adjusts the output power
factor cosφ in real time based on P/
Pn(%).
-
cosφ-P/Pn triggering
voltage
Specifies the voltage threshold for
triggering reactive power
compensation based on the cosφ-P
curve.
