A conventional turbine driven generator is converted to a synchronous condenser. The generator has a generator shaft; the turbine has a turbine shaft axially aligned with the generator shaft. The turbine shaft is disconnected from the generator shaft and an extension shaft is mounted on the generator shaft. The extension shaft has a journal bearing adjacent an axially outer end of the extension shaft, a thrust bearing, and provision for balancing the extension shaft and generator (now synchronous condenser) rotor.

A method of making a synchronous condenser from an electric generator driven by a steam turbine, said generator having a generator shaft and said turbine having a turbine shaft axially aligned with said generator shaft, said turbine shaft being connected to said generator shaft when said generator is driven by said turbine, said method comprising disconnecting said generator shaft from said turbine shaft, mounting an extension shaft on an end of said generator shaft coaxially and concentrically with said generator shaft to project axially outwardly from said generator, journaling said extension shaft in a journal bearing mounted against axial and radial movement with respect to the extension shaft, said extension shaft being journaled adjacent its axially outer end, mounting a thrust bearing assembly on said extension shaft, providing on said extension shaft means for balancing said extension shaft and generator shaft, and balancing said extension shaft and generator shaft.
