cos
φ
(P) procedure
In this procedure the cos
φ
displacement factor is used as control value.
Changing the displacement factor enables influencing the power fed in at the grid
connection point. The selected measuring device records the power P fed in at the grid
connection point and transfers the measurements to the data logger for this purpose.
The logger then assigns the cos
φ
control value to the relevant power, for example by
using a two-point characteristic curve.
Depending on the selected characteristic curve type, value pairs (interpolation points)
and the associated excitation types per interpolation point are needed in order to
produce the characteristic curve (line) for this procedure.
