The Influence of Cross-Magnetic Saturation and Iron Losses on the Electromagnetic Characteristics of a Frequency-Regulated Synchronous Reactive Machine

Abstract

On the basis of experimental data on the change in the instantaneous values of the longitudinal and transverse inductances of a synchronous reluctance machine caused by cross-magnetic saturation, the electromagnetic characteristics of the machine were determined for its various methods of frequency control (linking the change in the stator flux linkage module, longitudinal and transverse projections of the stator current with the developed electromagnetic moment of the machine). Using these characteristics, a vector control system is proposed, in which the this saturation is taken into account and the effect of iron losses on the electromagnetic characteristics of the machine is compensated.
