摘要
设计叶尖速比是风力机叶片设计中需要考虑的重要因素,文中分析了叶尖速比对叶片的弦长、载荷、气动性能、整机的功率和发电量等的影响,讨论了设计叶尖速比的选择。并分析得出增大设计叶尖速比,能够减小叶片弦长、载荷、成本,提高气动性能,但会使机组发电量有所下降的结论。
Design tip speed ratio has important role in wind turbine blade design. The influences of tip speed ratio to blade profile, load, power efficiency and power, energy output of wind turbine were analyzed. How to select TSR was discussed. The conclusion could be made that increasing design TSR could reduce chord, load, cost and so on, but could reduce energy output of wind turbine.
