ABSTRACT:
A turbomachine plant comprises a gas turbine, a synchronous electrical machine operable as a motor or generator, and a compressor all mounted on the same shafting and adapted to be coupled together for two optional operating modes. In a first operating mode, the gas turbine serves to drive the synchronous electrical machine for generation of electrical power and the compressor is not utilized. In the second operating mode, the synchronous electrical machine operating as a motor serves to drive the compressor for gas compression and the gas turbine is not utilized. When in the first operating mode the compressor is not disconnected by conventional clutch means from the gas turbine-synchronous electrical machine group but rather always remains connected to that group and is arranged by suitable valving so as to rotate in a vacuum type of operation with a power loss which is slight in relation to the gas turbine. If desired a permanent type of coupling can also be provided in the shafting between the gas turbine and synchronous electrical machine units in lieu of a disengageable clutch.
