After the Deneng Xiangjiang Hydropower Station replaced the 4-blade runner with a 5-blade runner, the unit started experiencing severe vibrations, which eventually led to coupling vibrations in the powerhouse structure and posed significant safety hazards. This paper explores the vibration source and employs Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) methods for analysis. Finally, modal verification through actual measurements validates the relevant conclusions. The study reveals that the resonance is caused by the multiple frequency relationship between the runner blade rotational frequency and the natural frequencies of the powerhouse structure. The research on the vibration issue at this power station hold great practical value.

德能湘江水电站将4叶片转轮改为5叶片转轮后,机组产生剧烈振动,并与厂房结构耦合振动,引发较大安全隐患。因此,对振源进行探索,并采用有限元分析(FEA)与计算流体动力学(CFD)方法进行计算分析,最后利用实测模态验证了相关结论。研究表明,水电机组与厂房耦合振动的原因为水轮机叶片转频与厂房结构的固有频率呈倍频关系。该研究对解决类似电站振动问题具有重要的参考价值。

德能湘江水电站将4叶片转轮改为5叶片转轮后,机组产生剧烈振动,并与厂房结构耦合振动,引发较大安全隐患。因此,对振源进行探索,并采用有限元分析(FEA)与计算流体动力学(CFD)方法进行计算分析,最后利用实测模态验证了相关结论。研究表明,水电机组与厂房耦合振动的原因为水轮机叶片转频与厂房结构的固有频率呈倍频关系。该研究对解决类似电站振动问题具有重要的参考价值。

After the Deneng Xiangjiang Hydropower Station replaced the 4-blade runner with a 5-blade runner, the unit started experiencing severe vibrations, which eventually led to coupling vibrations in the powerhouse structure and posed significant safety hazards. This paper explores the vibration source and employs Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) methods for analysis. Finally, modal verification through actual measurements validates the relevant conclusions. The study reveals that the resonance is caused by the multiple frequency relationship between the runner blade rotational frequency and the natural frequencies of the powerhouse structure. The research on the vibration issue at this power station hold great practical value.
