In this paper the influence of the wave oscillation on the behavior of floating off-shore wind turbine is analyzed. Aerodynamic analysis of forces on wind turbine blade has been carried out as a function of the wind turbine tilt angle due to wave oscillation. This analysis has resulted in a theoretical model based on the variation of the angle of attack which allows the characterization of the turbine under the effect of the oscillation of the sea surface. The results obtained show the influence of the oscillation in a particular case and its impact on the generated power. Subsequently, a so-called “pitching compensation” system that allows eliminating the effect produced by the variation in the angle of attack and, therefore, minimizing the effect of oscillation on the power generated, is proposed.
