Improved Methodology For Considering The Frequency-Dependent Behaviour Of Electrical Machine Windings In Transient Simulation

Résumé

The development of electrical machine winding models capable of predicting the inter-turn voltage distribution has been widely reported in the literature. However, the existing models have difficulty in accounting for the frequency evolution of the winding parameters during transient simulation. The aim of this paper is to present an improved method for incorporating the high frequency-dependent behaviour of electrical machine windings in transient simulation. First, the proposed lumped parameter model of the winding is presented. The particularity of the model is that it includes the resistive and inductive coupling between the turns of the winding. The parameters of the winding model are estimated using the finite element method and analytical equations. The circuit model incorporates frequencydependent parameters through the utilization of behavioural voltage sources. The proposed equivalent circuit is then transformed into a reduced nodal admittance matrix in order to estimate the node voltage at a particular turn in the frequency domain. An inverse Fast Fourier Transform is then performed to calculate the node voltage in the time domain. As a first step in the validation of the proposed methodology, a series of comparison tests with previous models have been carried out.
