In recent years, there has been a rapid development of wind farm. It is important to investigate the wind turbine arrangement in wind farm, especially with a high turbulence intensity found in the complex terrain. Therefore, by varying turbulence intensity with active turbulence grid, a wind tunnel experiment with two model wind turbines was carried out. The velocity distribution of rotor wake and power output and blade flapping moment of wind turbine in the rotor wake are measured.These measurements show that as increase of turbulence intensity of the inflow the velocity in the rotor wake recovers rapidly and power output of the turbine in rotor wake recovers. Furthermore, the blade flapping moment of the rotor in wake becomes smaller as increase of turbulence intensity. Higher turbulence encourages the admixture of rotor wake and free flow and it weakens the velocity gradient at the edge of rotor.
