Rotor design and analysis of stall-regulated horizontal axis wind turbine

Wind energy provides energy security at a time when decreasing global reserves of fossil fuel threatens the long-term sustainability of energy supply. The power performance of a wind turbine depends on the site´s wind speed distribution and the design characteristics of the wind turbine. Based on the relationship between the power performance and the rotor parameters, this paper addresses the design tip speed ratio, rated wind speed, rotor diameter, and blade geometry of a stall-regulated wind turbine. As a case study, a dedicated aerofoil is used for the design and analysis of a stall-regulated wind turbine blade based on a specific wind speed distribution.
