520 Reactive PwCtrl
Description
This function is available for
DK LVD
,
DE LVD
,
DE MVD
grids.
This function can be used to determine a separate cos φ for four
different power ratios P/P
n
(see Fig. 10.3 auf Seite 58).
P/P
n
is the ratio between the current active power and the rated
power of the solar power inverter. Power ratio and cos φ are
assigned to points in pairs. The power ratios for points A and D are
fixed at 0%/100%. For points B and C, the power ratios can be con-
figured within the predefined limits. The cos φ can be configured for
all four points.
For example, the parameters
B P/Pn ratio
and
B cos phi
belong to point B. The parameters
A P/Pn ratio
and
D P/Pn
ratio
are not displayed, since they are fixed at 0%/100%.
Power ratio point D = 100 %
