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_refimag(Y_ref) < 0: inductive caseB_actual are proportional
to f_ref/fAdmittance, Resistor, Conductor, Capacitor, Impedance, Variable resistor, Variable conductor, Variable capacitor, Variable inductor, Variable impedance, Variable admittance
