Multiphase linear impedance

Information

The impedance model represents a series connection of a resistor and either an inductor or capacitor in each phase.

The linear impedance connects the voltage v with the current i by v = Z*i in each phase, using m singlephase impedances. The resistive components are modeled temperature dependent, so the real parts 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:

(a) imag(Z_ref) > 0: inductive case
The actual reactances X_actual are proportional to f/f_ref
(b) imag(Z_ref) < 0: capacitive case
The actual reactances X_actual are proportional to f_ref/f

Multiphase linear admittance

Information

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 singlephase 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:

(a) imag(Y_ref) > 0: capacitive case
The actual susceptances B_actual are proportional to f/f_ref
(b) imag(Y_ref) < 0: inductive case
The actual susceptances B_actual are proportional to f_ref/f

Multiphase variable impedance

Information

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 singlephase 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:

(a) imag(Z_ref) > 0: inductive case
The actual reactances X_actual are proportional to f/f_ref
(b) imag(Z_ref) < 0: capacitive case
The actual reactances X_actual are proportional to f_ref/f

Note

Zero 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.
