cos
φ
(AI)
With this procedure, the displacement factor cos
φ
is used as the control
value. The AI requirement is provided by the grid operator as an analogue
input signal, e.g. analogue ripple control receiver and connected to the
analogue input of the PCU.
The value is provided by the grid operator as an analogue input signal (4 –
20mA).
The displacement factor is calculated from the analogue value via a linear
equation. For the configuration, the value pairs P1 and P2 are required,
which are at the end of the line. Furthermore, the excitation type per point is
required.

Note:
Feedback can be provided via the analogue output of the
PCU.
A simultaneous use of the analogue input for active/and
reactive power procedures is not possible.
