A Modelica Library for High-Voltage AC Circuit-Breaker Modeling
Jörg Lehmann, Daniel Ohlsson, Hansjürg Wiesmann · Linköping electronic conference proceedings · 2009
The efficient simulation of the current interruption phase in high-voltage circuit breakers is routinely performed based on integral models for the gas dynamics and the arc physics.We present a Modelica framework for such a model.Based on Modelica.Media, a thermodynamic library for the required temperature and pressure range has been developed.Making use of the latest Modelica.Fluid library and the new streams concept, a library for the gas dynamics and the arc physics in such systems has been implemented.
