Abstract: A power plant and a method for operating such a power plant having at least one generator, which is cooled by a cooling gas cooled by a generator heat exchanger, and a closed cooling water system, to which the generator heat exchanger and additional heat exchangers of the power plant are connected, wherein the generator heat exchanger is a component of an additional cooling water circuit, which serves solely to cool the generator, which is connected to the cooling water system and can be selectively disconnected therefrom by at least one shut-off valve, and which has a pump and at least one refrigerating machine for cooling the cooling water flowing through the additional cooling water circuit.

Abstract: A gas turbine power plant and a method for operating a gas turbine power plant are provided. The power plant includes a gas turbine installation which may supply a mains supply network with electric power and includes a compressor and an associated first gas turbine. Differing from previous gas turbine installations, the compressor of the gas turbine installation and the first gas turbine of the gas turbine installation are decoupled from each other. A second turbine is provided which drives compressor. As a result, the compressor of the gas turbine installation is operated independently of the first gas turbine. Influences on the mains supply network side, such as generating deficiencies in the main supply network, which act upon the first gas turbine as a result of speed reduction, are also not able to have an impact upon the compressor which is decoupled from the first gas turbine.
