<p>A hydroelectric power installation utilizes an array of turbine generators which are assembled at an elevated position above water and are moved as a unit to a submerged, operating position at the entrance of a discharge conduit. The assembled turbine generators and draft tubes are lowered to the submerged position along a track leading to the entrance of the conduit, and are placed in sealing relationship with the conduit in the submerged position to permit power to be generated from the full pressure head of the water.</p> |
