Abstract
PurposeThe phase-domain synchronous machine model has advantages compared to the d/q model, as no transformation of currents is necessary at each time step in a network analysis. The purpose of this paper is to enhance the phase-domain model to calculate the current distribution of the damper bars, including the saturation.Design/methodology/approachThe new enhanced phase-domain model of the synchronous machine has been modelled using Matlab-Simulink. The parameters of the model have been calculated by using FEA software.FindingsIt is shown that the simulation results of the new model show very good accordance to the reference model during a three-phase short circuit.Originality/valueThe enhanced model includes the calculation of the currents in the damper bar and is able to include the harmonics of the inductances.
