Description
Specifies the power threshold for
stopping underfrequency-caused
raising.
Specifies the frequency threshold
for power raising.
Specifies the exit frequency of
power raising caused by
underfrequency.
Specifies the minimum power
factor for Q-U adjustment.
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.
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).
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 output
power factor cosφ in real time
based on P/Pn (%).
