能提供低成本风电的新型风力机(中文+外文共5000字)
【摘要】第一代商用扩散体增强型风力机(DAWT)在新西兰刚开始两年试运行,如果开发者的预期结果得以实现,这种新设计的风力机可促使风电成本大幅度降低。
   在距新西兰奥克兰南约100km的Waikaretu的一座小山顶上,一台革命性的新型风力机正在进行为期两年的试运行。这座风力机的外观与常规风力机相比完全不同,其高度为17m,很象一巨物蹲在山顶上,而常规风力机则为一细长体,高高地矗立在山顶上。
   这是投入运行的第一代商用扩散体增强型风力机(DAWT: diffuser augmented wind turbine),如果开发者的预期结果得以实现,将导致风力发电成本大幅度降低。在试验新的风力机技术的同时,也可以试验扩散体环罩的新材料、高强钢丝纤维加强的钢筋混凝土。此种风力机在当地被称为"混凝土风力机"。在商业上,它被称为Vortec7型风力机,因为它有一个7m直径的转子。

Low-cost wind power can provide a new wind turbine
Abstract: The first generation of commercial proliferation of enhanced wind turbine (DAWT) in New Zealand has just begun trial operation two years, if the developers to achieve the expected results, this new design of wind machines to be significantly reduced cost of wind power.
   New Zealand in the distance about 100 km Aokelannan the Waikaretu on top of a hill, a revolutionary new wind turbine is a two-year trial operation. The wind machines and the appearance of conventional wind turbine completely different compared to its height of 17 m, much like a Juwu squatted on the Peak, and the conventional wind turbine is a slender body, tall and towering over the top of the hill.
