Power plant assembly comprising a gas turbine, a generator and a steam turbine, and method for operating the same

摘要

The power plant (1) has a gas turbine (2), a generator (3) and a steam turbine (4) with a high pressure-part turbine (5), a medium pressure-part turbine (8) and a low pressure-part turbine (11), where the gas turbine and the steam turbine are coupled to the generator. A clutch (19) is arranged between the generator and the high pressure-part turbine. Another clutch (20) is arranged between the medium pressure-part turbine and the low pressure-part turbine. The former clutch and the latter clutch are formed as a switchable clutch. An independent claim is included for a method for operating a power plant.
