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.
