Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed accordin

IEC61400-1第三版 极限载荷外推-wind turbine load extrapolation for iec 61400-1,2005

风电塔架风速时程曲线与风荷载时程曲线模拟。本代码依据IEC 61400-1标准，用于模拟具有一定功率谱密度和自相关性的风速时程曲线，并计算叶片及塔架上的风荷载。方法为基于三角级数叠加的谐波合成法（Hansen，2008）和叶素动量法。功率密度谱采用Kaimal谱函数。-Curves of wind speed and wind load-time curve Cheng wind tower. The code according to
