Q(DI) procedure
In this procedure the reactive power Q is used as control value.
The specified target value is provided by the grid operator as a digital input signal, for
example via a remote control system connected to the digital inputs of the blue’Log.
The digital signals are assigned to the percentage 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.
