4.8.10 "PFCtlW" Procedure
For the "PFCtlW" procedure, the power factor is set depending on the feed-in power. The dependency
is depicted by a parameterizable curve. The parameters of the curve may be set to either make it rise
or fall. The starting and end points of the characteristic curve can be set via parameters.
Figure 16: Curve for reducing reactive power depending on active power
On the basis of a linear characteristic curve with an upper and lower limit, a power factor can be
regulated dependent on the active power fed in at the time. The starting and end points of the
characteristic curve can be set via parameters. The course of the characteristic curve is determined
by the setting of the starting and end points.
