<p>A power generating unit (10) comprises a gas turbine (11') with an air intake section (12), a compressor (13), at least one combustor (14, 16) and at least one turbine (15, 17), and further comprises a gas-cooled generator (18), being driven by said gas turbine (11) and having a generator cooling system (20) comprising at least one cooler, through which cooling water flows, and which removes heat from said generator. A more flexible operation of the unit can be achieved by connecting said generator cooling system (20) to an air intake heat exchanger (30) arranged within said air intake section (12) of said gas turbine (11) in order to transfer heat from said cooling water flowing through said generator cooling system (20), to the air flowing through said air intake section (12).</p> |
