Hengeve H.J., Lysen E.H., Paulissen L.M. Matching of Wind Rotors to Low Power Electrical Generators

Amersforst: Steering Committee for Wind Energy in Developing Countries, 1978. — 90 p.The aim of this publication is to give the reader guidelines to design a small-stale wind electricity conversion system. The emphasis lies on the electrical part of the system and its optimum matching to the rotor. The theory and the design of the wind rotor itself can be found in other publications.
In chapter two the basic components of a wind-electricity conversion system are summarized. Then the matching of wind energy supply and
electric energy demand is treated. The main charter on the conversion to electric power starts with a short summary of the characteristics of a wind rotor and subsequently treats the different existing electrical machines. This chapter concludes with the analysis of the matching of rotor and generator, As the S.W.D. programme focuses on rural applications in developing countries, the given examples relate to small-scale wind systems, generating DC power and equipped with some battery storage. The last chapter is devoted to the storage of electricity. . It is assumed that the reader has some knowledge of basic technical physics, As the understanding of electrical machines is essential for this publication the authors have devoted one appendix to "What happens in a generator?"
