風車の運転方法の検討を目的としたリアムコンパクトによる数値風況診断 : 串木野れいめい風力発電所を例として

摘要

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 window risk assessment) was performed, has conducted studies safe windmill operating method In this paper, under the cooperation of Kyudenko new energy Co., Ltd., Numerical wind conditions diagnosis for the purpose of examination of windmill 10 Unit method of operation of the kushikinoreimei wind farm (start the operation from November 2012) since the was carried out, we report on the results.%最近になり、複雑地形上に建設された風力発電所に おいて、稼動率が当初の予想を下回る、すなわち、発電 出力が著しく悪い風車や、風車内外の故障(例えば、ョ 一モーターゃョーギアの故障、風車ブレードのクラックな ど)の問題が顕在化している。この主たる原因は、風車直 近の僅カゝな地形起伏の変化が起源となり、そこから発生 する風の乱W地形乱流)であると考えられる。
