| 摘 要： | 在建立反映风剪切、塔影效应因素的并网双馈发电机系统的数学模型的基础上,针对并网风力机输出功率中主要的闪变频率设计了闪变抑制控制器,控制器中PID参数采用遗传算法进行离线整定。仿真表明,该控制方法可以有效地抑制并网双馈风力机引起的电压闪变。

| Abstract: | The paper develops a mathematical model for grid-connected DFIG wind turbines by considering the wind shear and the tower shadow effects.A flicker mitigation controller is designed at the main flicker frequency in the output power of grid-connected DFIG wind turbines.It takes genetic algorithm on off-line tuning of PID parameters.The simulation results show that the ways and means are an effective means for flicker mitigation of grid-connected DFIG wind turbines. |
