Steady-state analysis of a permanent-magnet-assisted salient-pole synchronous generator

This paper presents a simple mathematical model for the steady-state analysis of a permanent-magnet-assisted salient-pole synchronous generator (PMa-SG). The PMa-SG is a new type of salient-pole synchronous generator that has permanent magnets (PMs) between the adjacent pole shoes. The developed model takes into account the magnetic saturation and core loss and enables quantitative predictions of load characteristics from the no-load test data. The validity of the developed model is confirmed experimentally. The effect of the PMs on the performance characteristics of the PMa-SG is also investigated.
