Modelling method for complex induction machines used in naval applications using an advanced simulation concept

To be able to guarantee high availability of naval drives and power-supply systems, error scenarios have to be simulated. At this, the chosen set of differential equations has to model the physical behavior of complex induction machines used in naval applications, e.g. induction machines with 5- or 7-phases or with double-star stator windings including asymmetric faults which is not featured by any simplified single-phase ECD. After a brief introduction of the used simulation concept, an approach for modeling complex motor drives is presented. The excellent performance is demonstrated with the simulation of a three-phase induction machine emulating an failure occurring in one inverter phase leg.
