 Abstract:

This paper developed an enhanced saturation model for synchronous machines based on simulation and experimental evaluation. The effect of taking account of cross-saturation is demonstrated. Local saturation factors are defined so as to adjust the flux-density distribution. The method of saturation modelling of dumper synchronous machine with and without cross-saturation is identified. Examples of numerical simulation are given to verify the model and its applications. Through experiments, it is shown that, by using the relationship between magnetizing current and flux as modelled in this paper, the nonlinear behavior of the synchronous machine is quite accurately estimated. Furthermore, the new model is compared with a classical model that neglects mutual saturation effects between a quadrature and direct axis windings.
