Abstract

The paper presents a simplified model of a switched reluctance motor (SRM) and its generic implementation in a popular electromagnetic transient program. The nonlinear flux linkage-current relationship at a given rotor angle is realized as the weighted sum of magnetic characteristics at two extreme rotor positions. The SRM model is interfaced with the rest of the network (modeled within the electromagnetic transients program) as a set of Norton current sources. Special measures are taken to mitigate numerical instabilities. A major benefit of the developed model is that it enables the simulation of one or several SRM drives embedded in a larger electrical network.
