STUDY OF TRANSIENT AND STABILITY OF SYNCHRONOUS RELUCTANCE MOTOR USING COMBINED FEM-CIRCUIT MODEL CONSIDERING CROSS MAGNETIC SATURATION
electrical machines and drives
In this paper, a combined FEM-circuit model of the Synchronous Reluctance Motor (SynRM) is presented, in which the lumped circuit parameters are calculated numerically using FEM. The inductance cross-magnetic saturation is considered and used as lookup table in the circuit model. This model combines the advantages of both methods; the accuracy of FEM and ability to include geometrical and physical effects relevant to non-linearity, in addition to the speed of circuit models and ability of simulating controller/drive applications or simulating the effect of unbalanced/non-ideal supply. The dynamic operation and stability limits at supply voltage sag are also investigated to demonstrate the importance of including non-linear cross-magnetic effects in circuit models using the proposed approach.
