EPGS architecture with multi-channel synchronous generator and common field regulated exciter

摘要

A generator system includes a generator 52 haying a stationary portion 60 and a rotating 61. The generator includes an exciter field winding 62 disposed on the stationary portion. A first channel includes a first main field winding 72 and a first main field power converter 78 disposed on a rotating portion. The first main field power converter selectively delivers voltage from the exciter winding the first main field winding. A second channel includes a second main field winding 74 and a second main field power converted 80 disposed on the rotating portion. The second main field power converter selectively delivers voltage from the exciter winding to the second main field winding. A generator control unit is connected to the first channel and the second channel. The generator control unit monitors an output voltage at each of the first channel and the second channel and generates the first and second control signals based on the output voltage.
