摘要:

为有效的利用风力资源和土地资源,使风力机间的尾流影响降到最低。利用Fluent软件对同方向来流的两台风力机的风电场,在3个不同间距条件下模拟出风力发电机组运行工况下的流场,并分析不同间距条件下的风力机整机气动性能的特点和差异,以及尾流对下风向风力发电机组功率的影响,观察其叶轮表面以及整机的压强分布、流速分布、湍流强度、流速矢量等流态图,并对风电场风力机的布置提出建议。

For effective use of limited land where ample wind resources exist, and in order to reduce the wake interaction between wind turbines, a numerical simulation has been carried out to two turbines on the same direction flow in different spacing using software Fluent. The analysis of the aerodynamic performance and characters and the influence of the wake effect on the power of the downstream turbine is provided according to the pressure distribution, velocity distribution, turbulence intensity and velocity of the impeller and the whole wind turbine. At last, suggestions on the best arrangements of the wind turbines are presented.
