摘　　要：混流式水泵水轮机要在水泵和水轮机两个方向运行,电站前期论证工作中很难有恰好合适的转轮与给定电站参数完全匹配。通过对以往抽水蓄能电站机组参数的统计,归纳总结出系列公式,在未获得与电站参数相匹配模型转轮条件下给出机组主要参数合理范围,并为电站模型开发提供方向性保障。The mixed-flow pump-turbine has two operation modes of pump and turbine,so in the preliminary study process,it's hard to find a complete matching runner for the given parameters.The present studies conclude the series of formulas based on the statistics of existing pump-turbine units and give a reasonable range of parameters when there's no matching model runner.The work gives direction guarantee to the model development of power generation stations.
