Abstract: The invention relates to a generator system for generating an increased braking power, in particular during the startup and/or powering down of a turbine, drivingly connected to a generator, of a turbine system, e.g. a CAES system. The generator system includes the generator, which for generating current is drivingly connected to the turbine, and a transformer, which is connected on the primary side to the generator and on the secondary side to an external current network. A means for frequency adaptation is disposed between the generator and the transformer and is expediently embodied as capable of being put on line. By putting the means for frequency adaptation on line during the startup and/or the powering down of the turbine system, the turbine is acted upon by a greater braking power. In this way, the development of ventilation in the turbine can be largely avoided.

Abstract: A steam power plant with retrofit kit has a steam generator (1) with superheater, a steam turbine set including condensation installations (11), connecting pipelines, auxiliary devices and a generator (10). The steam power plant (22) is distinguished by the fact that the retrofit kit includes a retrofit turbine module (25) which is designed for elevated temperature and for unchanged or modified pressure and is connected upstream of the existing steam turbine set or is exchanged for the high-pressure turbine of the latter. Furthermore, a method for retrofitting an existing steam power plant includes the following steps: connecting a retrofit turbine module (25) for high operating temperatures and unchanged or modified operating pressure upstream of the existing turbine set or exchanging the existing high-pressure turbine for the retrofit turbine module (25); providing a steam generator (1) and/or superheater (32) for high live steam temperature.

Abstract: In a method of manufacturing a plurality of steam turbines for use in various applications which differ in the respective thermodynamic parameters such as, for example, cooling-water temperature, ambient temperature, given boiler data, process-steam requirement, etc., the steam turbines in each case having at least one high-pressure part with first blading and a control-wheel stage for part-load operation, a simplification and cost saving is achieved owing to the fact that standard blading, which is identical for all the steam turbines, is used as first blading, and in that the adaption of the individual steam turbine to the thermodynamic parameters of the respective application is carried out by appropriate design or variation of the control-wheel stage.
