摘要
采用多流管理论模型对风光能源复合发电装置项目中H型垂直轴风机参数进行优化设计,在多流管理论基础上建立模型并用Matlab软件进行计算、仿真。分析了H型垂直轴风力机叶片在旋转过程中不同叶尖速比时攻角的变化情况,以及叶尖速比、密实度对风力机风能利用系数的影响。通过各个参数大小的变化对功率系数的影响进行比较,得出最大功率时所对应的风机最佳参数。
The multi-stream-tube theoretical model is used to optimize the parameters of H-type vertical axis wind turbine in wind-solar composed power generation project. Based on the multi-stream-tnbe theory, a model is established, and calculated and simulated by using Matlab software. The changes of the attack angle of the vane of the rotating H-type vertical axis wind turbine under different tip speed ratio is analyzed. The influence of tip speed ratio and density on wind energy utilization coefficient is analyzed emphatically. Through comparing the influence of the changes of various parameters on the power coeffieient, the optimal parameters of wind turbine at uhimate power output are obtained.
