A Re-Engineered Modelling and Simulation Environment for Teaching Generalised Machines Theory

Abstract

CASED, a drive simulation tool, is re-engineered to allow non-specialist users to model and analyse complex drive systems. The shortfalls of the CASED system are overcome by re-engineering it to resemble the machines and drives domain with the use of visual interactive modelling while retaining the inherent strengths of the CASED simulation engine. Visual CASED's ease of use has been demonstrated through its use as a teaching aid for a Generalised Machines course at the Department of Electrical Engineering, University of the Witwatersrand. As an example of its use, the transient effects of a resistance starter on a 75 kW wound-rotor induction motor driving a conveyer load are investigated.
