A NOVELYAWCONTROL METHOD FOR WIND TURBINES BASED ON PREDICTED WIND DIRECTIONS

提出一种基于风向预测的新型控制方案,该控制方案涉及一种新颖的控制结构,包含风向预测模型和新型偏航控制。在上述控制结构下,利用基于自回归综合移动平均线的卡尔曼滤波模型来预测风向,同时提出一种基于有限控制集的模型预测控制方法。为证明所提方案的可行性和优越性,开发一种新型偏航控制器并用工业数据进行仿真测试,然后将其性能与工业偏航控制器相比,结果表明新型偏航控制器具有更小的偏航误差,因此增加了最大风力获取能力。

A novel yaw control method for wind turbines based on predicted wind directions is proposed in this study.Specially,the proposed solution refers to a novel control structure that consists of a wind direction predictive model and a novel yaw control method.Under the proposed control structure,a hybrid autoregressive integrated moving average method-based Kalman filter model is used to predict the wind direction,and a novel model predictive control using a finite control set is proposed.To demonstrate the feasibility and the superiority of the proposed solution,the novel yaw controller is developed and tested through some simulation tests using industrial data.The performance is compared to the industrial yaw controller.Comparison results show that the novel yaw controller can reduce yaw error,and thus increase wind power extraction for the WTs.
