超低水头水轮发电机组优化选择

Optimum selection of water turbine generator units with ultra-low head

对于超低水头水电站应优先选用三叶片贯流式水轮机。必要时可加装增速齿轮箱,以提高发电机转速、降低建设投资。同时,要优化流道设计并从各个方面来提高超低水头电站的设计水平与设备采购能力,杜绝落后的设计方案与低价中标的采购方式。

As to ultra - low head hydropower stations, it is .preferable to select three - blade tubular turbines. Speed increasing gear cases can be, inst＇,dled （ if necessary. ） to boost generator speed and reduce construction cost. At the same time, it shall optimize flow passage in every aspect to improve the design of ultra - low head hydropower stations and procurement capability of equipment, in order to reject laggard design schemes and procuring manner of contract award by lower price.
