Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a simple voltage-frequency-controller. The amplitude of the voltage is linear dependent (VNominal/fNominal) on the frequency (input signal u), but limited by VNominal (nominal RMS voltage per phase). An
m quasi-static phasor signal is provided as output signal y, representing complex voltages.
The output voltages may serve as inputs for complex voltage sources with phase input. Symmetrical voltages are assumed.
