中文摘要：

机舱风速计测量功率曲线的误差较大,造成风电功率预测结果的不确定性。文章依托某风电场现场实验,研究了机舱风速-自由流风速的关系,探讨了大气湍流强度对机舱传递函数（NTF）的影响,提出了基于湍流的双NTF方法,并应用于机舱风速计测量功率曲线。在不同年平均风速情况下,采用未修正的机舱风速功率曲线、国际电工委员会（IEC）提出的单NTF方法修正后的机舱风速功率曲线和文章所提出的双NTF方法修正后的机舱风速功率曲线,分别评估年发电量,其误差范围分别为-8.8%~-0.5%,-2.4%~-0.2%和-0.2%~0.2%。研究结果表明,文章所提出的基于湍流的双NTF方法是可行的,其应用效果优于IEC提出的单NTF方法。

英文摘要：

The power curve measurement with nacelle anemometer has significant error, and it also brings the uncertainty in Wind Power Prediction（WPP）. Based on field experiment in a wind farm,this literature investigated the nacelle wind speed-free flow wind speed relationship,studied atmospheric turbulence intensity＇s effect on the Nacelle Transfer Function（NTF）, and then propoed a turbulence based dual-NTF method, which can be applied to power curve measurement with nacelle anemometer. For various annual mean wind speed conditions, the error ranges of calculated energy production based on no-corrected, the International Electrotechnical Commission（IEC） single-NTF method corrected and this paper＇s dual-NTF method corrected nacelle wind speed power curves were-8.8% ~ 0.5%,-2.4% ~-0.2% and-0.2% ~ 0.2%. The results indicated the turbulence based dual-NTF method proposed in this paper is feasible, and its application effect is superior to the IEC single-NTF method.
