摘　　要：风力发电机组叶片在设计、制造、现场安装和实际运行过程中,可能造成实际最优桨距角不再是模型设计时的最优桨距角,降低了机组的性能。如何快速、有效地寻找最优桨距角来提升机组运行性能成为亟待解决地问题。文章提出了一种最优桨距角自寻优控制算法,构造了最优桨距角评价函数,来自动寻找模型的最优桨距角,并以国产某1.5 MW风力发电机组为例进行仿真验证。结果表明,所提出的自寻优控制算法能够自动寻找出实际的最优桨距角,验证了文中方法的可行性和有效性,为提高风力发电机组的性能提供了科学的依据。Wind turbine blades in the process of design,manufacture,installation and operation,may cause the really optimal pitch angle is no longer the best pitch angle of model design,and reduce the performance of wind turbine.How to quickly and effectively find the optimal pitch angle to improve the performance of wind turbine has become the urgent problem to be solved.The selfoptimizing optimal pitch angle control algorithm was presented in this paper,and constructed the optimal pitch angle evaluation function to automatically find the optimal pitch angle of model,Taking 1.5 MW wind turbine as an example,this algorithm was simulated based on the GH Bladed software in this paper.The simulation results show that the proposed self-optimizing control algorithm can automatically find the actual optimal pitch angle.It is easy to verify the feasibility and validity of the proposed method,and provide a scientific basis for improving the performance of wind turbine.
