摘要 为研究带非同步导叶(MGV)装置的水泵水轮机无叶区的压力脉动特性,以某抽水蓄能电站模型水泵水轮机为研究对象,基于分离涡湍流模型,针对水泵水轮机在低负荷工况下预开导叶对无叶区流动的影响,选取预开导叶分别为24,33 mm下的水轮机工况为研究对象, 并设计4种非同步导叶布置方案,通过全三维流道数值模拟分析得到机组在低负荷启动时振动的最优方案.结果表明:在预开导叶相对应位置的无叶区处,具有较大的压力脉动幅值;集中分布预开导叶对转轮振动的改善效果优于等间隔分布预开导叶方案;最终选择预开7#,8#和17#,18#这2对活动导叶组情况下对水泵水轮机机组振动的改善效果最为明显.

Abstract: In order to study the characteristics of pressure fluctuation at low load of pump turbine with the Misaligned Guide Vanes(MGV)in the vaneless space, the model pump turbine of a pumped storage power station served as the research object. Based on the detached eddy simulation method, we studied the flow in the vaneless space and analyed the influence of pre-opened guide vanes on the flow, besides a pump turbine with pre-opened guide vanes with angle 24° and 33° was modeled, and four MGVs were designed, in the hope of finding the most optimal solution to the vibration of the pump turbine at low load through fully three-dimensional numerical simulation of flow. The analysis results of the four pre-opening programs show that a region at the wake of pre-opened guide vanes and close to the pressure side of blade has a larger pressure amplitude. And equally-distributed guide vanes are better than centrally-distributed ones in improving pressure amplitude. It is concluded that the program of 7#,8# and 17#,18# two-pair guide vanes can most effectively mitigate the pump turbine vibration.
