Power Converters For Wind Energy Conversion Systems

This book focuses on modeling, control, and implementation of power converters for Wind Energy Conversion Systems (WECS). The book begins by introducing the fundamentals of wind energy systems, including their configurations and the role of power electronics in efficiently converting mechanical energy into electrical energy. It presents a detailed classification of power converters used in modern WECS, covering conventional two-level and three-level voltage source converters, current source converters, matrix converters, and passive converters associated with polyphase generators. The second part of the book focuses on the modeling and control of power converters, providing in-depth coverage of analytical methods and advanced control strategies such as Direct Torque Control (DTC), Rotor Flux Oriented Control (RFOC), and predictive control methods. Each control approach is illustrated with examples, equations, and simulation studies, enabling readers to understand the impact of control parameters on system performance. The final section demonstrates the practical implementation of a universal wind turbine emulator based on three-phase induction motor drives and various power converter topologies. It presents experimental results validating the effectiveness of the control strategies, including torque response, flux regulation, and harmonic performance. This book is particularly relevant for graduate students, researchers, and practicing engineers working on wind energy systems, power electronics, and advanced motor drives, offering them both foundational knowledge and innovative solutions.
