Abstract:
This article presents an original modelling of a high speed double stator permanent magnet synchronous machine (DSPMSM). When a turn-to-turn short-circuit fault occurs in the stator windings, the current flowing in the short-circuited turns can be much higher than the phase current. And the unbalance between the phases caused by the fault makes the phase voltage unmeasured. For overcoming this problem, a reconfiguration modelling method is proposed. The reconfiguration is a model which input line voltage rather phase voltage that can be measured correctly even if the machine is unbalanced. This advanced model is familiar with the classical d-q model. Therefore the traditional vector control algorithm is still available, the machine can be controlled by using the same signals (measured phase currents at the inverter level and DC bus voltage). A simulation of a DSPMSM variable speed drive shows the relevance of the model.
