Mathematical modeling and numerical simulation of locomotives electrical drive systems in modelica

The main goal of the present paper is to show how the Modelica modeling language can be used for modeling a locomotive electric drive system. The key properties of the Modelica language are described while the components of the referred drive system are modeled. Among the drive components are a synchronous generator, induction motors, electronic power converters and associated controllers that are modeled by means of the Modelica language and OpenModelica standard components. All results were obtained with the OpenModelica simulation platform.
