Wind characteristics measurement was conducted at one of sites suitable for wind turbine generation in Japan using ultrasonic anemometers and cup anemometers. In particular, it is considered that ultrasonic anemometer is more suitable for analysis of turbulence and gust characteristics, because it does not have moving mechanisms. The reliability of NEDO Field Test data for turbulence intensity analysis used in the 1st report of this study was evaluated by this measurement data. Gust characteristics in wind models of the IEC 61400-1 (Ed. 3) were also analyzed, and those gust characteristics are compared with the current IEC gust model and new gust criteria obtained by integrating the new turbulence criteria proposed in the 1st report. As a result, it was found that the most drastic gust event measured in this study could be more severe than the Extreme Operation Gust (EOG) model in the current IEC 61400-1 (Ed. 3). It was also found that the amplitude of EOG model is adjusted by incorporating with the new turbulence criteria. Therefore, the conformity of the new turbulence criteria to other wind models was somewhat confirmed in this research.
