Quasistatic Single Phase Impedance

Single phase linear impedance

Modelica Standard Library

	Description
	The Quasistatic Single Phase Impedance component connects the complex voltage $v$ with the complex current $i$ by $v = Z v$ , where $Z$ is complex. The model includes a Conditional heat port and temperature dependency of the real part of the impedance.

	Equations
	$i = i_{p} = - i_{n}$ $v = v_{p} - v_{n} = (R_{actual} + j X_{ref}) i$ $R_{actual} = R_{ref} (1 + α_{ref} (T_{hp} - T_{ref}))$ $ω = {\overset{&period;}{γ}}_{p}$ $γ_{p} = γ_{n}$ $P_{loss} = ℜ (v \overset{&conjugate0;}{i})$ $T_{hp} = {\begin{array}{c} T_{heatPort} & Use Heat Port \\ T & otherwise \end{array}$
