| 摘 要： | 为提高风力机发电系统的风能利用效率、改善输出电能质量,针对变速变桨风力发电机组的控制问题,以混杂系统理论为核心,建立了应用于变速变桨风力机组的混杂自动机控制结构。同时,结合模糊控制理论,给出控制器的算法。通过对该控制结构和控制算法的仿真表明,与常规的控制方法相比,采用混杂自动机控制结构和控制算法控制变速变桨风力机组,既提高了风能的利用效率,又很好地改善了风力机输出电能质量,实际控制效果良好。

| Abstract: | In order to increase the utilization efficiency of wind energy of wind turbine power generation system,and improve the quality of output electric energy,with the chaotic system theory as the core,the control structure of chaotic automation used for variable speed and variable pitch wind turbine is established.In addition,combining with fuzzy control theory,the algorithm of controller is given.The simulation of the control structure and control algorithm shows that comparing with conventional control method,the variable speed and variable pitch wind turbine with chaotic automation control structure and under control algorithm reaches predicted target,the practical control effect is excellent. |
