Model of a three-phase balanced impedance.
If inductive=true, then the inductance is a
parameter, otherwise the capacitance is a parameter.
The boolean parameter star is used to select
whether the star (Y) or triangle (D) configuration is used to
connect the impedance. By default, the impedance is assumed to be
connected with a star configuration.
When the connection type changes from star to
triangle, the value of the impedance is recomputed in
such a way that the nominal power consumed by the impedance does
not change.
PhaseSystem.thetaRef out of
derivative operator as this is not yet supported by JModelica.
