| 摘 要： | 湍流强度是影响风电机组疲劳载荷和极限载荷的重要因素。文章基于云贵地区某风电场的实际测风资料,使用CFD(Computational Fluid Dynamics)软件Meteodyn WT计算风电场的湍流强度;对WT软件输出的湍流强度矩阵进行分析处理,将结果与IEC61400-1风机标准中正常湍流模型(NTM)进行对比,以判断湍流强度是否超出,从而评估风电场安全性。针对WT软件无法直接输出湍流代表值I ref的问题,提出了一种估算I ref的方法。

| Abstract: | Turbulence intensity has an important effect on fatigue load and ultimate load of wind turbine. Based on the wind measurement data of a wind farm in the Yunnan-Guizhou plateau, the turbulence intensity was calculated by CFD software Meteodyn WT. Turbulence matrix exported from WT was analyzed and the analysis result was compared with NTM of IEC61400-1 standard for wind turbine to assess turbulence intensity, thereby evaluating safety of wind farms. In addition, a method to calculate Iref is proposed regarding the problem that turbulence typical value Iref cannot be exported directly from WT. |
