风速和电功率之间的关系-功率曲线-在风电场的设计、管理和功率预测中是必不可少的。功率曲线是风力涡轮机的主要特性，并提出了一种方法来确定后，风力涡轮机安装和运行。该程序是基于计算和统计技术，在现场测量，机舱风速和操作数据。这可以作为国际电工委员会标准中完全基于现场测量的程序的替代或补充，减少这种做法的时间和成本。以一个运行一年以上的风电功率预测系统的预测误差来衡量一个更准确的功率曲线的影响，从而提出了数值现场校准的方法，并引入了理想功率曲线和机舱功率曲线的概念。验证的基础上安装在风力发电场在复杂的地形，在葡萄牙的风力涡轮机的数据，提供了一个真实的测试这里提出的技术。功率曲线对风电功率预测不确定性的贡献为均方根误差的10%~ 15%。版权所有© 2013约翰威利父子有限公司.
The relation between wind speed and electrical power—the power curve—is essential in the design, management and power forecasting of a wind farm. The power curve is the main characteristic of a wind turbine, and a procedure is presented for its determination, after the wind turbine is installed and in operation. The procedure is based on both computational and statistical techniques, in situ measurements, nacelle anemometry and operational data. This can be an alternative or a complement to procedures fully based on field measurements as in the International Electrotechnical Commission standards, reducing the time and costs of such practices. The impact of a more accurate power curve was measured in terms of the prediction error of a wind power forecasting system over 1 year of operation, whereby the methodology for numerical site calibration was presented and the concepts of ideal power curve and nacelle power curve introduced. The validation was based on data from wind turbines installed at a wind farm in complex topography, in Portugal, providing a real test of the technique presented here. The contribution of the power curve to the wind power forecasting uncertainty was found to be from 10% to 15% of the root mean square error. Copyright © 2013 John Wiley & Sons, Ltd.
