Optimization of dual stator winding configuration for enhanced performance of synchronous reluctance generators

Abstract

This research presents a comparative analysis of dual stator winding configurations in synchronous reluctance generators (SRGs) aimed at enhancing energy efficiency and dynamic performance. Facing the growing demand for reliable and cost-effective generators, particularly for applications like diesel gensets and renewable energy integration, this study investigates single-layer versus two-layer stator winding arrangements. Through simulation analysis, the impact of varying the relative phase displacement between the main and excitation windings in the two-layer design is examined. Findings indicate that a two-layer configuration with an optimized two-slot phase shift significantly reduces torque ripple and output voltage harmonics while achieving a high efficiency of 92.5% for a 160kW SRG model.
