风力机设计软件WTD1．0气动设计性能分析

为了研究分析风力发电机设计软件WTD1．0（一套基于考虑了流动三维气动效应数学模型的设计软件）的性能，选取一实际的风力机为计算模型。对WTD在叶轮功率计算、叶片的安装角分布、风轮的转速、叶片翼型弦长分布、叶片扭转角分布设计等方面的功能进行了计算分析，并对WTD在叶轮的启动力矩、多叶片（叶片数超过6片）叶轮的气动计算和设计的功能等进行了分析研究。通过计算分析，发现设计软件WTD1．0在叶轮功率计算、叶轮结构尺寸设计、叶轮启动力矩计算及多叶片叶轮计算设计方面均有较好的表现，并能正确地反映风力机叶轮的气动理论，在一定程度上提高了风力发电机的气动设计水平。

STUDY OF THE PERFORMANCE OF AERODYNAMICS DESIGN OF WIND TURBINE DESIGN SYSTEM WTD1.0

The analyses were carried out in this paper of the functions of rotor power calculation,blade pitch angle design,rotor rotating speed design,blade chord distributing design,and blade twist distributing design of WTD.The studies were also made of the performance of rotor starting moment calculation and multi blade (over 6 blades) rotor design.In order to investigate the performance of aerodynamic design of wind turbine design system WTD1.0 with three dimensions flow modification,a real wind turbine was selected as a computing model.The analyses and studies show that WTD1.0 has quite a good performance at rotor power calculation,rotor and blade design,rotor starting moment calculation,and multi blade rotor design.It can predict aerodynamic characteristics of wind turbine fairly correctly.In brief,WTD has improved the contemporary design capabilities and efficiency of aerodynamic design of wind turbines.
