Polyarmonic model of synchronous generator for analysis of autonomous power generation systems

This paper presents the polyharmonic modelling of synchronous generator (SG) in machine variables. The simple geometry and windings physical layout has been used for inductance calculations of a salient-pole SG. The main advantage of this model is the ease of describing an autonomous power generation system (APGS) in terms of its topology and thus providing effective analysis at the static and dynamic states, both for normal and fault operations. Particularly, the model can be used to obtain SG voltage and currents for their more extensive harmonic analysis. Comparison of the simulation and measurement results has shown their good agreement, i.e., validating the elaborated polyharmonic model of SG.
