Calculation of a Current Vector Trajectory for Enhanced Operation of Synchronous Reluctance Generators Including Saturation

Autor: Alvaro E. Hoffer, Roberto H. Moncada, Boris J. Pavez-Lazo, Juan A. Tapia, Lasse Laurila

This article proposes a simple method to calculate a current vector trajectory for the enhanced operation of the electric power generation system based on a synchronous reluctance machine (SynRM). Owing to magnetic saturation and cross magnetization,
