摘要/Abstract

摘要： 针对机舱风速理论修正方法计算偏差较大的问题,根据风力发电机组控制策略对整个风速范围进行分区,通过高阶多项式拟合来确定机舱风速传递函数,建立一种基于测风塔测风数据的机舱风速修正方法。采用该方法进行风速修正不仅能够克服IEC机舱传递函数实用性较差的问题,而且较不分区的简单线性拟合又具有较高的拟合精度,通过引入过渡区间改进了分段机舱传递函数所存在的不连续问题。算例结果与数据分析表明了该机舱风速修正方法的优越性。

Abstract: In consideration that there are great calculation errors in theoretical correction of nacelle wind speed, the entire range of wind speed was divided according to changes of control strategies for wind turbine generation unit. The nacelle transfer function (NTF) was defined by higher-order polynomial fitting to identify a method for correcting nacelle wind speed based on wind measurements of the anemometer tower. It doesn’t only overcome problems like poor practicability of IEC standards NTF, but also has higher fitting precision than simple linear fitting without intervals. By introducing intermediate intervals, the problem about discontinuous NTF in different sections has been improved. The calculation example suggest that the above method is high advantageous in correcting nacelle wind speed.

Key words: wind turbine, nacelle wind speed, wind speed correction, nacelle transfer function
