大容量风力发电机组的设计

Design of large Wind Turbine

为了浓缩风能,把载有风力机翼的转动箱置入固定翼箱中(参照图1)。本文对扩散管(dif-fuser)作了特殊研究,以高效率的扩散管为设计基础,以内蒙古作为设计对象。由于风被浓缩后利用,地面风速为8m/s 时,风力机处的风速为12.6m/s,此时风力机的输出功率可以达到5180KW。当纵方向5台重叠时,总输出可以达到25MW。因为能达到大功率输出,所以每台风力机可以根据风速大小,用大小两台发电机发电,机组年运转率比其它类型风力发电机组高。

To concentrate the rare wind energy,I used a wind turbine which has a rotor cased out-side the windmill,In this paper,a plan which have a high efficiency diffuser,is suggerted andthe computing method for diffuser efficiency by using empirical data.Applying this plan inInner Mongolia,I designed a wind turbine which had a 5180KW electrical output capacitywhen wind velocity is 12.6m/s equal to ground velocity of 8m/s.Also I showed a 25MW gen-erating plant with piling up 5 of those units.This generating plant has two generators perone windmill.This generating plant produce a higher working ration than other similar units.
