Francis turbine-generator unit

The Francis turbine generator unit is a reaction type hydroelectric generating set (per IEC TR 61364 standard), the most widely adopted turbine solution for hydropower stations. Water flows radially into the runner circumference, turns downwards and discharges axially from the runner outlet. The flow drives the runner to rotate, converting hydraulic energy into mechanical energy, which further drives the generator to produce electric power. It is applicable for net head ranging from 20 m to 700 m.
