The impedance model represents a series
connection of a resistor and either an inductor or capacitor in
each phase.
The linear impedance connects the complex voltage
v with the complex current
i by i*Z = v
in each phase, using m
variable single-phase impedances. The impedances Z_ref =
R_ref + j*X_ref are given as complex input signals,
representing the resistive and reactive components of the input
impedances. The resistive components are modeled temperature
dependent, so the real part R_actual = real(Z)
are determined from the actual operating temperatures and the
reference input resistances real(Z_ref).
Conditional heat ports are considered. The reactive components
X_actual = imag(Z) are equal to
imag(Z_ref) if frequencyDependent =
false. Frequency dependency is considered by
frequencyDependent = true, distinguishing two
cases:
imag(Z_ref) > 0: inductive caseX_actual are proportional to
f/f_refimag(Z_ref) < 0: capacitive caseX_actual are proportional to
f_ref/fZero crossings of the real or imaginary parts of the impedance
signals Z_ref could cause singularities due to the
actual structure of the connected network.
