Part 1-Hydro turbine type and runner type
According to the power conversion methods of the runner, hydro turbine can be divided into reaction turbine(the hydraulic energy transfers to the runner with main enable power and kinetic power as supplement) and impulse turbine(the hydraulic energy transfers to the runner with full kinetic power).
