LARGE SINGLE-PHASE TURBINE-GENERATOR SETS FOR TRACTION POWER SUPPLIES

EINPHASEN-BAHNSTROMTURBOSAETZE GROESSERER LEISTUNG

Between 1951 and 1971 the unit ratings of turbine-generator sets for traction power supplies have increased twelvefold, especially due to the application of hydrogen cooling to single-phase generators. In the new sets, the gear required to reduce the turbine speed of 3,000 rpm to the generator speed of 1,000 rpm is not arranged between the turbine and generator but between the high-pressure and intermediate/low-pressure sections of the turbine. Hence it need not be designed for the full generator output. The 138- to 225-MVA hydrogen-cooled single-phase generators are derived from the field-proven air-cooled model for 62.5 MVA. Its typical design features have been retained.
