Purpose of the study is to develop a new and reliable method for the power curve measurement of wind turbine generator system in complex terrain. Since the power absorbed from the wind is proportional to the third power of the wind speed, essential problem in complex terrain is how to measure the real wind speed into the rotor plane of wind turbine. To take account of the effect of topography, a site calibration procedure based on the sectorwise two-poit correlation analysis has been performed. In this paper, the influence of wind characteristics and turbulent intensity for the power curve measurement of NEDO-500kW wind turbine is investigated and discussed. The measurement campaign has been perfomed in Tappi wind park from 1996 to 1998.
