Abstract:

Leigongtan Hydropower Station is a low head one with reservoir of daily regulation performance, so the unit parameter and rated head of the hydraulic turbines in selection will directly affect the investment and the economic benefits of the project. By comprehensively considering the fact that the hydropower station is in a boundary water head zone, and through the analysis of the investment and energy characteristics of different units under different rated head solutions, we compared the running stability and economic benefits of the units in selection. Finally, the Leigongtan Hydropower Station adopts Bulb tubular turbine and the rated head is 14.53m.

Key words: boundary head, rated head, hydraulic turbine, low-head hydropower station, Leigong Hydropower Station
