Comparative Study of Different Types of Wind Turbine and an Overview of Some Issues Related with Wind Energy (original) (raw)

As energy demand around the world is increasing day-by-day, wind energy is the good option for energy generation. The most common type of wind turbine is horizontal axis wind turbine (HAWT), but there exist other types. In this paper four different wind turbines are considered, three vertical axis wind turbines (VAWT): the Savonious, the Darrieus, the Giromill or H-rotor; and the HAWT. This study deals with the comparative study of these four different types of wind turbines from the most important aspects including design, construction, maintenance, blade profile. In this study it has been found that VAWT is more advantageous over HAWT in several aspects. Furthermore, different economic, environmental, technical and social issues related with wind energy are discussed. Keywords— Darrieus, Giromill, HAWT, H-rotor, Savonious, VAWT.
