详 情 说 明

The present thesis delves into various aspects of the control system design, analysis, and grid synchronization of a Doubly-Fed Induction Generator (DFIG) that is driven by a wind turbine. The DFIG is a unique type of induction machine that consists of two back-to-back converters. The first converter interconnects the stator of the DFIG with the grid, whereas the second converter is linked to the rotor of the machine through a DC-link capacitor.

The thesis presents a detailed account of the control system design, which is based on the stator-voltage and stator-flux oriented frames. It provides a comprehensive analysis of the control system that has been developed, which includes the mathematical modeling, simulation, and experimental results of the DFIG system. The thesis also explores different techniques that can be employed for grid synchronization of the DFIG, with a particular focus on the synchronization of the stator voltage with the grid voltage.

Moreover, the present work also discusses the potential applications of DFIGs in the field of renewable energy and power generation. It highlights the advantages of using DFIGs in wind turbines, as they offer higher efficiency, better power quality, and improved reliability as compared to other types of generators. Finally, the thesis concludes with a discussion on the future scope of research in this area, which includes further improvements in control system design and grid synchronization techniques.
