This work is basic study to show the effect of terrain for the performance evaluation of a wind turbine generator system (WTGS) in complex terrain. Since the wind energy captured by the rotor of WTGS is proportional to the 3rd power of wind speed, the exact estimation of the wind speed at wind turbine constructed point are needed. However, the definitive method for the wind speed estimation in complex terrain has not yet been established. In this study, the effect of slope at the upwind of turbine has been investigated by means of numerical simulation using k-ε turbulent model. The results of simulation have shown that the wind energy obtained by rotor plane considerably depends on the position and hub height of the turbine for the incline angle of the slope.
