老江底水电站水轮机水力稳定性分析

摘要

After putting into operation of 4 098 h, the outlet edge of runner blades in Laojiangdi Hydropower Station emerges a large number of cracks. The unit selection, blade material and operation mode are analyzed to find the reasons of blade cracking and the solutions are also proposed. The study can be as reference for the unit selection and design of similar hydropower stations.%老江底水电站投入运行4098 h后,水轮机转轮叶片出水边出现大量裂纹,为此对机组选型、叶片材料以及运行方式等进行了分析,研究产生叶片裂纹的原因,提出解决问题的方法,可供同行在机组选型设计以及电站运行中参考.
