Abstract: A hydroelectric installation comprises an electric generator and associated hydro-turbine. The hydro-turbine comprises a runner rotatably mounted within a casing or passageway in which water flows between an upper elevation source in fluid communication with an inlet port and a lower elevation discharge region or outlet port. The turbine also includes a water closure component or head cover. The generator is laterally supported by a guide bearing attached to a turbine component thereby eliminating the use of generator guide bearing brackets, bridges and the like, and reducing the complexity of the concrete structures surrounding the unit.

Abstract: A hydroelectric power generating module comprises an upper housing section and a lower base section connected to the upper housing. The upper housing has a plurality of generators situated therewithin, and the lower base has a plurality of water flow paths extending therethrough. Each water flow path comprises an upstream water inlet, a downstream draft tube, and a distributor disposed intermediate the draft tube and the water inlet. The water inlets are defined by a plurality of horizontal members interconnected with a plurality of vertical members to form an array of water tubes having generally parallel axes. A plurality of turbines is provided wherein each turbine has a runner rotatably mounted within an associated water flow path downstream of an associated distributor. The runners are mechanically coupled to the generators for generating hydroelectric power by rotation of the runners when water travels through the water flow paths.
