Inverter reactive power setting: Cos(
Φ
) – P curve
The power related control mode cos
φ
(P) controls the cos
φ
of the output as a function of the active power output.
There are four coordinate points that can be adjustable in the curve as below figure.
The coordinate points are the active power as a percentage of Pn and the displacement factor cos
φ
.
Some grid company maybe requires two voltage thresholds as a percentage of Un to activate or deactivate the function.
The voltage thresholds normally call ‘lock-in’ and ‘lock-out ’voltage.
Activation threshold as a percentage of Un corresponds to ‘lock-in’ voltage
Deactivation threshold as a percentage of Un corresponds to ‘lock-out’ voltage
