摘　　要：为了对比钢管格构式和圆筒式塔架对风力机尾流扰动特性,首先根据塔架的控制荷载,设计承载力和高度相同的直筒式塔架和钢管格构式塔架。然后在Fluent中,完成2种塔架风力机的流场计算,得出两者塔架近尾迹流场、远尾迹流场及风力机和塔架风荷载的特征。对比结果表明:1)钢管格构式塔架的顺风向风荷载和横风向风荷载的波动幅度远低于圆筒式塔架,有利于减小结构疲劳破坏风险并降低结构的风振系数;2)钢管格构塔架的尾流流速及湍流强度的恢复距离低于圆筒式塔架,有利于提高风力机的排列密度;3)钢管格构式塔架风力机的叶片阻力和功率与圆筒式塔架基本相同。To compare the disturbance properties of latticed and pipe tower on wake of wind turbines,firsty,a lattice and a circular pipe wind turbine tower are designed with th same height and loading capacity;Secondly,the fluid simulation is finished in the software Fluent and the properties of the near wake,far wake and wind load of the wind turbines with two types of towers is calculated.The comparsion showed that:1)The fluctiuation of the cross and down wind load of lattice tower is far less than those of the circular pipe tower,which helps to decrease the failure of fatigue and the wind vibration factor;2)the recovery length of velocity and turbulent intensity for the latticed wind tower is less than those of circular pipe tower;3)the down wind load of the blades and the power rate of the turbine of the latticed tower is slightly less than those of the circular pipe tower.
