Abstract: A hydroelectric power generation apparatus includes a braking force generation unit configured to apply a braking force to rotation of a hydraulic turbine, and a controller configured to control the braking force generation unit to repeat increasing and decreasing the braking force to vary a rotational speed of the hydraulic turbine. Varying the rotational speed of the hydraulic turbine helps to flow away debris and the like adhering to hydraulic turbine blades. Preferably, the braking force generation unit includes an electrical, mechanical or fluid type braking device configured to apply a braking force to a rotary shaft of the hydraulic turbine. Preferably, the braking force generation unit includes a power generator configured to generate power through rotation of the hydraulic turbine, and the controller increases/decreases the braking force by varying power extracted from the power generator.
