摘要 在分析风能的特性、风速区域划分以及大型风力发电机组常用控制方法的基础上,指出当前控制中存在的滞后、大惯性等问题.针对这些问题,提出基于风速预测的新型变桨距协调控制方法,在高于额定风速的情况下,加入风速预测环节,从而克服风速测量滞后、桨距角调节惯性大等问题.这种控制方法将小波变换嵌入时间序列法中,用于建立ARMA模型进行风速预测,然后将预测的风速送入控制环节,具有较好的动态控制性能.最后,通过实例仿真验证了该设计方法的有效性. Based on analysis of the characteristics of wind energy, wind speed regionalization, and commonly used methods for control of large-sized wind turbines, this paper discusses the delay and significant inertia problems in control of wind turbines. To solve these problems, a new method for variable-pitch coordinate control based on wind speed prediction is proposed. In this method, performing wind speed prediction can overcome the obstacles caused by the delay of wind speed measurement and the inertia of the pitch angle above the rated wind speed. The ARMA model was established and the wind speed was predicted using the time series model through wavelet analysis, and then the predicted wind speed was transmitted into the control unit. The method was shown to have good dynamic control performance. The results of simulation show that this method is effective.
