Description
Specifies 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.
Specifies the P/Pn when the
device exits the Q-U scheduling.
Specifies the minimum power
factor for Q-U adjustment.
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).
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).
Specifies the time for filtering
the grid voltage in the PF-U
curve.
The device adjusts the output
power factor cosφ in real time
based on P/Pn (%).
Specifies the voltage threshold
for triggering reactive power
compensation based on the
curve.
Specifies the voltage threshold
for exiting reactive power
compensation based on the
curve.
Specifies the adjustment time for
the reactive power to reach the
target value during reactive
power adjustment.
