Abstract Recently to become, in wind farm, which was built on the complex terrain, the operation rate is less than the initial expectations, ie, power generation output and significantly bad windmill, failure ...of windmill inside and outside (for example, failure of the yaw motor and Yogia, windmill blades cracks, etc.) of the problem of is actualized. The main cause is a change in the windmill most recent slight terrain relief becomes origin, I considered to be a disorder of the wind (terrain turbulence) generated from there. In response to this situation, in our group, precise numerical wind diagnosis by real terrain version RIAM-COMPACT® software (the wind risk assessment) was performed, has conducted studies safe windmill operating method^(1)). In this paper, Kyudenko Corporation under the cooperation of the New Energy Co., Ltd., as the target of the 10 Unit kushikinorei wind farm (operation started in November 2012), for the purpose of windmill optimal placement study that takes into account the wind turbine structural strength conditions, since it was carried out numerical wind conditions diagnosis, to report on the results.show more
