Abstract A power plant includes a gas turbine coupled to an electric generator. The electric generator can be connected to a high-voltage network through a generator switch and can be operated as a motor for the start-up of the gas turbine. The electric generator can also be connected to a static starting device for the run-up of the gas turbine. The static starting device is connected to a medium-voltage network which is provided for the auxiliary service of the power plant. The auxiliary voltage, provided in another way, of the medium-voltage network, produces a variable supply voltage for the generator operated as a motor, thus circuitry can be predigested.
