ABSTRACT:
The power plant comprises a gas turbine module and a steam turbine having a high pressure portion with or without a medium pressure portion, and a low pressure portion mounted on a common shaft line driving an alternator disposed at the end of the line of shaft, the stator of the gas turbine being supported on a base integral with a foundation via supports having low stiffness in translation, and also being secured to the stationary portion of an abutment for the shaft line, wherein the shaft line is provided with an abutment whose stationary portion is mounted on the foundation and is disposed between the two fixing points on the foundation of the stators of the low pressure portion and of the high pressure portion, with or without a medium pressure portion. The invention is applicable to reducing expansion along the single shaft line, and to increasing efficiency.
