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_refimag(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.
