摘要： 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.

摘要： A reclosing apparatus for the auxiliary systems of a plant, in particular a power station, has drive modules (81) for actuating electrical drives (23a, 23b, 33, 53a, 53b, 63, 73) of the auxiliary systems. Each drive module (81) of a reclosable drive (23a, 33, 53a, 63, 73) is assigned a reclosing module (82). When a voltage interruption occurs, the reclosing modules (82) switch the drives (23a, 33, 53a, 63, 73) by opening switches (22a, 32a, 52a, 62, 72). If the end of the voltage interruption is detected within a predetermined time, the reclosing modules (82) switch the drives (23a, 33, 53a, 63, 73) on again. Each busbar (2, 3, 5, 6, 7) which supplies a drive (23a, 33, 53a, 63, 73) provided with a reclosing module (82) is equipped with a microprocessor-controlled voltage monitoring device (21).
