The influence of solidity and aspect ratio on power coefficient of H-type vertical axis wind turbine, and the change of attack angle with tip speed ratio were analyzed. 采用多流管模型分析了H型垂直风力机展弦比和实度对其功率系数的影响,并对叶片旋转过程中攻角随尖速比的变化进行了分析。
Simulation results show that the fuzzy Control System had tracked of the best tip speed ratio when the wind speed is low, and get a stable output power when the wind speed is high. 仿真结果证明,模糊控制系统在低风速时很好的跟踪了最佳叶尖速比(TSR),在高风速时得到了稳定的输出功率。
The control strategies under different wind speed have been analyzed and obtained the optimal tip speed ratio using the simplex algorithm. 分析了不同风速下的控制策略,应用单纯形加速法确定最优叶尖速比(TSR)。
Based on the model, the paper studies how to design wind turbine controller, enables the system operating in the vicinity of the maximum power point, when the wind speed below the rated wind speed. That is the tip speed ratio lies in the optimal value. 在建立的模型基础上,研究了当风速在额定风速以下时,如何设计控制器使得风力机运行在最大功率点附近,也就是说将叶尖速比(TSR)控制在最佳值。
The reliability of blade is directly related to the safe operation of the entire system, the rotational speed and tip speed ratio is a directly affects the performance of the wind turbine. 叶片的可靠性直接关系到整个系统的安全运行,叶片的转速、尖速比等直接影响风力发电机的性能。
