摘 要:
根据风速指数规律分布,采用三种计算过程,对风轮扫掠面积上的真实风功率做了定量计算.数值积分计算结果表明,在四类廓线指数、七种塔架高度情况下,风速梯度对气动设计影响甚微,采用风轮中心风速做为单一的设计风速是切实可行的.[著者文摘]

Abstract:
The power of the wind passing through the rotor swept area was analysed and calculated based on the wind velocity exponential distribution with three calculation methods. The result of numerical integration showed that wind velocity gradient had only a little influence on aerodynamic design of wind turbine. Thus, taking the wind velocity at the rotor center as its design velocity would be feasible for four wind shear exponents and seven tower heights.[著者文摘]
