Abstract

Determining the best geometric parameters for the blade of a wind turbine is criticalfor maximizing energy production. This paper considers howto determine the laws which governtwist to maximize electrical energy output for a rotor with two blades, with a 10m diameter, in agiven wind site.Optimum twist was obtained by applying the ‘blade element momentum theory’. Then twodifferent blade design methods were compared. The first, based on maximizing the power coefficient(at the average wind velocity, assuming an attack angle which maximizes the ratio of liftand drag coefficients); the second, based on maximizing the annual energy production for theturbine object of this study, in a given wind site.
