AdmittancePolyphase linear admittance |
SystemModel["Modelica.Electrical.QuasiStatic.Polyphase.Basic.Admittance"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The admittance model represents a parallel connection of a resistor and either a capacitor or inductor
in each phase.
The linear admittance connects the voltage v
with the
current i
by i = Y*v
in each phase, using m
single-phase admittances.
The resistive
components are modeled temperature dependent, so the real parts G_actual = real(Y)
are determined from
the actual operating temperatures and the reference input conductances real(Y_ref)
.
Conditional heat ports are considered.
The reactive components
B_actual = imag(Y)
are equal to imag(Y_ref)
if frequencyDependent = false
.
Frequency dependency is considered by frequencyDependent = true
, distinguishing two cases:
imag(Y_ref) > 0
: capacitive caseB_actual
are proportional to f/f_ref
imag(Y_ref) < 0
: inductive caseB_actual
are proportional to f_ref/f
