摘要

The generator (1) has a dual drive containing two drive machines (2,3) with at least one mechanical coupling (8,9,11,12) to the generator each and a slip ring arrangement (4), whereby the generator is mechanically coupled via a generator shaft (13b) to a slip ring shaft (13d). A first gearbox shaft (13c) of a gearbox is arranged between the generator shaft and the slip ring shaft and the second drive machine (3) is connected to a second gearbox shaft (13g). The first machine (2) is a gas turbine and the second a steam turbine
