Modelling and simulation of multiphase IM with sinusoidal flux distribution used in naval applications including torque calculation

To guarantee high availability of naval drives and power-supply systems, error scenarios have to be simulated. The chosen differential-equations set has to represent the physical behaviour of complex naval induction machines, e.g. with 5- or 7- phase or double-star stator windings including asymmetric faults which is not featured by any simplified single-phase ECD. After a brief introduction of used simulation concept and modelling approach for motor drives with sinusoidal flux distribution, the torque calculation for n stator and m rotor windings is presented. The performance is demonstrated with the simulation of a five-phase induction machine emulating a single-phase failure.
