流溪河电站水轮机改造的水力研究

The Hydraulic Research for Hydraulic Turbine Rehabilitation of Liuxibe Power Station

采用ＨＬ６３８型转轮的水电机组是我国生产较久、品种较多的机型。本文结合电站具体情况，系统地介绍了流溪河电站ＨＬ６３８机组增容改造的水力研究及试验结果，该成果与上马岭电站、龙亭电站的成功经验为我国ＨＬ６３８型机组的电站开发改造提供了可供借鉴的经验。

The hydraulic turbine fitted with runner HL638 have been applied to power station for many years in our country.According to specific situation of Liuxihe power station,the hydraulic research and test results for runner HL638 and their rehabilitation are introduced in this paper.This achievement and the successful experience in Shangmaling and Longting power station can be used for reference to reform the power station fitted with HL638 runner in China.
