A hydroelectric power generating apparatus includes a check dam mounted on a hilltop portion of a hillside to accumulate water of a river reach, a power generating device mounted on a hill bottom portion of the hillside to be driven by a kinetic energy carried by the water for power generation, a diversion pipe extending from the check dam to the power generating device and having at least one diversion duct which extends along the river reach to make a pipeline that converts gravitational potential energy of the water into the kinetic energy, and a surge tank disposed to stand uprightly from the diversion duct for balancing pressure in the diversion duct.

A hydropower generator includes: a driving shaft installed along a path through which a fluid flows; a plurality of blade assemblies installed along a lengthwise direction of the driving shaft; a spinning supporter connected to rotatably support the driving shaft; a power generator receiving a spinning force of the driving shaft and generating electricity; and a flow pipeline internally provided with the driving shaft along a lengthwise direction thereof and formed with a channel through which a fluid flows.

The present invention is a hydroelectric power generating system having a siphon component, a generator component, and an electronics and control component, which produces an inflow of water caused by a vacuum initially created within the system and further aided by hydrostatic pressure. The inflow is directed to a ramp where it drives a water turbine located within the respective electrical generating system to produce electrical power.

A gravity driven hydroelectric system, whereby hydroelectric power is developed from potential energy of dammed water driving a water turbine assembly. The hydroelectric power extracted from the water depends on volume and on a difference in height between a source and an outflow of the water. A penstock delivers the water to the water turbine assembly. The penstock has a housing secured by frame assemblies to a structure. The housing has electromagnetic coils that produce electricity from a rotation of turbine blades having magnets.
