Small Wind Turbines Analysis, Design, and Application
The aim of Small Wind Turbines Analysis, Design, and Application is to demonstrate that, a century later, small wind turbines can be designed and built to avoid many of the problems that faced Grim wade. This is not to say that small turbine technology is mature; there are still areas where it lags well behind current practice for large turbines. This lag is mirrored in the theme of this book which is to provide basic analysis and design guidelines to allow a group of, say, senior engineering undergraduates or junior engineers to design and build a small wind turbine. The approach follows the ‘‘Simple Load.

Small Wind Turbines Analysis, Design, and Application Content
There is no equivalent to the SLM in the IEC standard for large turbines. There are at least five areas where a student or other design group would need additional specialist advice:
• Finite element analysis (FEA) for detailed stress calculations of the critical components
• Electrical engineering advice on the generator and rectifier and possibly the inverter and grid connection
• Detailed dynamics analysis for more accurate stress calculations and fatigue analysis
• Foundation design, and
• Control engineering help in devising and implementing a control strategy
This book is a distillation of more than twenty five years experience working in small wind turbine research, development, and commercial isation. Over the years, my work supported by the Australian Research Council, the NSW Renewable Energy Research and Development Fund, the NSW Renewable Energy Development Program, and the Asia-Pacific Partnership on Clean Development. A very important year spent at NASA Ames Research Center was funded by the U.S. National Research Council.
Small turbines differ significantly from large ones in blade design and manufacture. The main differences are: low operational Reynolds numbers (Re), the need for good low wind performance at even lower Re, and the structural requirements of more-rapidly rotating blades. These issues covered in the first six Chapters and culminate in Chap. 7 on multi-dimensional blade optimisation and manufacture.
