Harnessing the Potential of High-Efficiency Synchronous Generators in Wind Energy Conversion Systems

Dual Excitation Generators (DESGs) are a potential improvement in high-efficiency generator technology, but optimizing performance and control techniques remains a difficulty. This work focuses on a detailed examination of a 1.5 MW DESG, with the goal of identifying important electrical features for optimal control implementation using an analytical sizing method. The project also intends to present and evaluate a novel control mechanism, the Fractional Order Proportional Integral (FOPI) controller. The inquiry begins with a comprehensive literature analysis that categorizes DESGs and describes their many uses. Using experimental data, a custom mathematical model integrating spatial harmonics is created to improve model precision. The FOPI controller is then introduced and tested using simulations with the NREL lab's Fatigue Aerodynamic Structure and Turbulence (FAST) program. The study's findings show significant development in wind energy control systems, notably in terms of improving power extraction and velocity tracking. The FOPI controller appears as a revolutionary technology, providing greater stability and robustness in DESG control over its operating range.
