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. In such a plant, reduced circuit complexity is achieved by the fact that the static starting device is designed in such a way or can be activated in such a way that, after the run-up of the gas turbine, the static starting device itself produces the auxiliary voltage of the medium-voltage network from the voltage delivered by the generator.
