摘要

针对风电机组在风切变、塔影效应的影响下，如何减缓叶根挥舞弯矩进行了研究。提出了基于单纯形法的独立变桨控制策略，在保证风电机组功率控制的基础上，实现减缓叶根挥舞弯矩及其1P分量载荷的目的；分别将该方法和传统PI控制的独立变桨控制策略应用于4.5MW风电机组模型，并在湍流风况下进行仿真，对比分析叶根挥舞弯矩及其功率谱密度、机组输出功率。通过4.5 MW风电机组模型仿真运行数据分析，表明基于单纯形法的独立变桨控制策略能够有效减缓叶根挥舞弯矩及其1P分量，且能稳定输出功率。

Abstract

This paper studies how to mitigate the blade root flap-wise moment of wind turbine under the influence of wind shear and tower shadow effect. An individual pitch control strategy based on simplex method is proposed to mitigate the blade root flap-wise moment and its 1p component load on the basis of ensuring the power control of the wind turbine. This method and the individual pitch control strategy of conventional PI control are applied to a 4.5 MW wind turbine model

and simulation is carried out under turbulent wind conditions to compare and analyze the blade root flap-wise moment

its power spectral density and the output power. The analysis of the simulation operation data of the 4.5 MW wind turbine model shows that

the individual pitch control strategy based on the simplex method can effectively mitigate the blade root flap-wise moment and its 1p component

and stabilize the output power.
