低水头水电站机组的造价占电站总投资的比重很大,尤其是贯流式机组,如何简化机组的结构对节约投资是很明显的.我们设想将贯流式水轮机的活动导叶改为固定导叶,依靠转轮叶片调节流量进行了水力性能的试验研究,获得了较好的效果,並对不同类型导叶出口边流场分布进行了测试工作、为今后的导叶设计提供了参考依据.
The cost of low-head hydropower units accounts for a large proportion of the total investment in power plants, especially for the cross-flow units, so how to simplify the structure of the unit is very significant for saving investment.We envisage changing the guide vanes of the tubular turbine to a fixed guide The experimental results show that the flow field at the outlet of guide vane is tested by the experimental results of the hydraulic performance of the rotor blade. The experimental results provide a reference for the design of guide vanes in the future.
