10.3.3.9 Displacement Power Factor cos φ as a Function of Feed-In Power: PFCtlW
Mode
In the PFCtlW mode, the displacement power factor cos φ is set as a function of feed-in power. This dependency is
depicted by a configurable characteristic curve. The characteristic curve can be configured as increasing or
decreasing. The start and end points of the characteristic curve can be configured by means of parameters.
Figure 24: Characteristic curve for reducing reactive power as a function of active power
On the basis of a linear characteristic curve with an upper and lower cap, a displacement power factor cos φ can be
regulated depending on the active power currently being fed in. The start and end points of the characteristic curve
can be configured by means of parameters. The shape of the characteristic curve is determined by the start and end
points.
