摘要

George worked with an owner's design team on a 40-mw hydro plant. The team was reviewing the water-to-wire contractor's second design for a vertical Francis turbine-generator. The contractor had accepted comments on the first design except for one comment on the generator rotor. Despite the design team's questioning of a flat, steel disc proposed as the connection between the generator shaft and rotor poles, the contractor left it in the design. The design team had questioned the selection of a disc to support the rotor poles, based on lack of precedent and suspicion that severe vibration problems would arise from the lack of rigidity between the shaft and rotor poles. Turbulent flow through the runner when the gates were partially open could induce vibrations in the disc, perhaps enhanced by harmonic interaction with vibrations emanating from the space between the runner and turbine head cover. The design team asked the contractor to provide a precedent for the design.
