blockThreephaseSource
Basic single phase signal source
Extends from Modelica.Blocks.Interfaces.MO (Multiple Output continuous control block).
Information
This block allows to apply disturbances (steps) in frequency, amplitude and phase as well as
adding a negative sequence and/or a zero component to the three phase output signal y[3].
