Abstract:
1. A drive train for the transmission of a variable power at a variable input speed for a power generating station driven with a turbomachine, the drive train comprising: a power-split transmission for receipt of power from a single source, said power-split transmission having an input shaft, at least one first power branch, and at least one second power branch, wherein the first power branch drives an electric generator; a hydrodynamic circuit disposed at an output end of the power-split transmission, wherein the hydrodynamic circuit connects the first power branch and the second power branch and controls power flow so that the electric generator is driven at a speed that is substantially constant; and wherein the hydrodynamic circuit is a torque converter, the torque converter having a pump impeller connected to a rapidly spinning shaft of the power-split transmission, wherein the rapidly spinning shaft is an output shaft of the drive train to which the electric generator is connected, and wherein the rapidly spinning shaft is part of the first power branch.
