基于变增益变桨的直驱型风电机组控制算法研究

Research on Direct Drive Wind Turbine Control Algorithm Based on Variable Gain Pitch Control

文中针对直驱风电机组,以在低风速最大风能捕获和在高风速额定功率维持为控制目标,提出利用MATLAB优化的变增益变桨控制策略。并在两种风况下进行仿真实验,与Bladed的结果进行对比,验证了控制算法不但能够有效抑制转速超调,而且可以增强机组对风速扰动的鲁棒性。

In this paper,a variable gain and variable paddle control strategy optimized by MATLAB is proposed for the direct drive wind turbine,in order to capture the maximum wind energy of the low wind speed and maintain the rated power of the high wind speed.The simulation experiments are carried out in two kinds of wind conditions.Compared with the results of Bladed,it is proved that the control algorithm can not only effectively suppress the speed overshoot,but also enhance the robustness of the wind turbine to wind speed disturbance.
