Characteristic of Taperless Blade Wind Turbine

Abstract

Presently, source of energy in Indone sia is still predominated by fossil energy. Since fossil energy is limited and not environmentally friendly, alternative of energy should be considered to be implemented. As consequences, research in renewable energy field has developed due to a bove reason. One of renewable energy source is wind energy. The potential of wind energy in Indone sia is estimate d 9.290 MWe, and presently, the installed capacity of wind energy conversion system (WECS) approxima tely is 1.1 MWe. Nevertheless, there is problem in development of utilize of WECS in Indonesia , due to most of the WECS, which available in market, are not designed for Indonesia wind condition. Based on this fact, it is reasonable if the WECS whic h operated in Indonesia not working properly (in performance point of view). Blades in a WECS are the main components, which have major influenced on the performance of WECS. In this research, design of blades will be carried out based on predetermined power capacity, using wind velocity condition in Indonesia. As an outcome this research, concept of blade based on aerodynamic design have been proposed and ready to be implemented.
