The admittance model represents a parallel
connection of a resistor and either a capacitor or inductor in each
phase.
The linear admittance connects the complex voltage
v
with the complex current
i
by v*Y = i
in each phase, using m
variable single-phase admittances. The admittances Y_ref
= G_ref + j*B_ref
are given as complex input signals,
representing the resistive and reactive components of the input
admittances. The resistive components are modeled temperature
dependent, so the real part 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
Zero crossings of the real or imaginary parts of the admittance
signals Y_ref
could cause singularities due to the
actual structure of the connected network.
