山地风电场水平外推不确定度计算方法的适应性研究
Adaptability of uncertainty calculation methods for horizontal extrapolation in mountainous wind farms
摘要
Abstract
The quantification of horizontal extrapolation uncertainty is crucial for wind resource assessment in mountainous wind farms.However,the applicability of the two commonly used quantification methods—the one based on horizontal distance and terrain acceleration ratio,and the other one based on spatial extrapolation distance and other comprehensive influencing factors—remains unclear under such terrain conditions.There-fore,this study evaluated the adaptability of these horizontal extrapolation uncertainty calculation methods in mountainous wind farms using measured data from 16 meteorological towers in mountainous areas.First,the two methods were described in detail.Then,horizontal extrapolation uncertainty under various operational conditions in mountainous wind farms was quantified using these approaches.The calculated extrapolation un-certainties were compared with the target uncertainties calculated by Meteodyn WT to assess the applicability of each method.The research findings indicate that the method based on horizontal distance and terrain accel-eration ratio is significantly influenced by the terrain acceleration ratio and tends to underestimate the uncer-tainty of horizontal extrapolation.Therefore,it is recommended to avoid its application in complex terrains.In contrast,the method based on spatial extrapolation distance and other comprehensive influencing factors is notably affected by vertical distance,demonstrating good applicability in mountainous wind farms with verti-cal distances ranging from 60 to 300 m.关键词
