Title: Generator-stream turbine-turbocompressor string regulated by variation of a mains power supplied and by a live steam feed and method for operating the same

Abstract: A generator-steam turbine-turbocompressor-string is provided. The generator-stream turbine-turbocompressor-string includes a generator with variable frequency, a steam turbine and a turbocompressor which can be driven by the generator and/or the steam turbine. The generator and the steam turbine are coupled together to a shafting, wherein the generator may be electrically coupled to an electrical power supply system for power supply feeding and the steam turbine may be connected to a live steam feeding device for the feeding of live steam to the steam turbine, such that the generator-steam turbine-turbocompressor-string has a rotational speed which is controllable by varying the power supply feeding and/or by the live steam feeding.
