| Abstract: | In this paper,the selection on the upgrade schema and the case of the implementation for Jiangkou hydroelectric power station unit 2 were introduced.The necessity and employability of reform capacity extension of hydropower units for Jiangkou unit 2 have been studied.And a comparison between the results of these two conditions was made.By not changing the rated speed,the rated voltage and the flow passage of turbine,but the turbine runner,the winding of stator,and dispelling the defects of the unit,the turbine efficiency increases 6.8% and the power output per year improves 3.8%. |
