摘要
中小型水电站增效扩容技改过程中,水轮机的转轮选型很重要,既要考虑跟原机组的匹配,更要考虑改型后的效果。本文利用CFD分析,对改型前后两型水轮机的水流特性等做了对比,有针对性地提出了改型建议,对其他电站有一定的借鉴作用。
During the process of efficiency improvement and capacity expansion in small and medium-sized hydropower stations, it is very important to choose runners for a hydraulic turbine. We should not only concern about matching with original units, but also the influence of changing runners. This article used CFD Analysis, contracted water flow characteristics of two hydraulic turbines before and after changings, which may have a certain reference for other power stations.
