cos
φ
(DI) procedure
In this procedure the displacement factor cos
φ
is used as control value.
The specified target value is provided by the grid operator as a digital input signal. This
is possible for example via a remote control system connected to the digital inputs of
the blue’Log. The digital signals are assigned to the specified control values via a
bitmask.
Step 1
In Step 1, the digital inputs used are configured. Digital inputs of the blue’Log are
assigned to the reactive power procedure in the process.
