Energy saving in electric trains with traction induction motors

The real world processes involving energy and matter need to be linked to the technical and environmental engineering education, design and operation. Energy systems involving coversion chain processes are highly irreversible and, consequently, they could have low exergy efficiencies. In electric railway transportation systems, achieved energy provides a basis for increasing exergy efficiency, reducing both energy losses and environmental damage. Further on, achieved energy modeling can help in optimizing designs and making operating decisions.
