Generators play a pivotal role in the harnessing of wind energy, serving as the heart of wind turbines in the conversion of kinetic energy from the wind into electrical power. This book provides a comprehensive exploration of generators used in wind energy conversion systems (WECS), covering their design, operation, and optimization. Beginning with an introduction to wind energy and the significance of efficient generator design, the book delves into the fundamentals of generator technology, including electromagnetic induction principles and various types of generators employed in wind turbines.
