8.1.9 PFCtlW Procedure
For the procedure PFCtlW, the displacement power factor cos φ is set depending on the feed-in capacity.
The dependency is depicted by a parameterizable characteristic curve. The parameters of the characteristic curve may
be set as increasing or decreasing. The start and end points of the characteristic curve can be set via parameters.
Figure 23: Characteristic curve for reducing reactive power depending on active power
On the basis of a linear characteristic curve with an upper and lower limit, a displacement power factor cos φ can be
regulated dependent on the active power fed in at the time. The start and end points of the characteristic curve can be
set via parameters. The course of the characteristic curve is determined by setting the start and end points.
