Abstract: In an air-cooled high power generator (10) with static excitation means (19, 22, 24, 26), which static excitation means (19, 22, 24, 26) comprise a cooled rectifier bridge arrangement (26), design simplification, enhanced reliability and space savings are achieved by placing the cooled rectifier bridge arrangement (26) in a cooling air circuit (23) of said generator (10).

Abstract: In a power generating unit a high power generator (28) is connected to a main transformer (29) or grid by means of a generator bus bar (11). A plurality of main current carrying parts (12, 15, 17) and protection and/or excitation circuits (13,14, 16; 18-24) are arranged along the generator bus bar (11) between the generator (28) and the main transformer (29). A simplified and fault-protected assembly is achieved by integrating the main current carrying parts (12, 15, 17) and the protective and/or excitation circuits (13, 14, 16; 18-24) into one generator power module (10).
