modelVariableConductor
Extends from Interfaces.TwoPlug (Two plugs with pin-adapter, reference connection and declaration of voltage and current), Modelica.Electrical.Polyphase.Interfaces.ConditionalHeatPort (Partial model to include conditional HeatPorts in order to describe the power loss via a thermal network).
Information
The linear resistors connect the complex currents i with the complex
voltages v by v*G = i,
using m single-phase variable Conductors.
The conductances G are given as m input signals.
The conductor model also has m optional
conditional heat ports.
A linear temperature dependency of the conductances is also taken into account.
