摘要
Abstract
This study focuses on a hydropower plant(HPP)with a significant surplus water flow consistently throughout the year.The objective is to assess the feasibility of operating the turbine beyond its rated output,without any equipment modifications at this HPP,through numerical simulation computations.In the flow field analysis during turbine operation at three selected outputs beyond the rated capacity,the turbine exhibited a satisfactory internal flow state.Cavitation performance evaluation under these operating conditions confirmed compliance with requirements,considering the HPP's actual operating conditions of this HPP.Additionally,calculations involving pressure pulsation,rigidity,and strength under the maximum load operating condition at outputs beyond the rated output demonstrated the turbine's excellent stability and the alignment of the runner's rigidity and strength with the design requirements.关键词
