Wind turbines are getting larger, and the rotor diameter of 10 MW class wind turbine is nearly 200 meters. The difference of wind speed between the highest position and the lowest position in large rotor diameter will be large and the effect to power generation or effect to the fatigue by large fluctuation of wind load might be ignored. In offshore area, wind shear is not larger than onshore area, but that effect is also important. Authors developed a scale model of wind turbine which can be controlled 3 blade pitch angles individually and carried out model test in wind tunnel with modified wind shear. Firstly, wind speed distribution with honey comb board was measured and strong wind shear was modeled. Secondly characteristics of model turbine were measured in wind shear. Finally, individual blade pitch control was applied and its effect was observed.
